New micro/nano-manufacturing techniques are needed that can be combined with advances at the frontier of molecular engineering . To address this need, an innovative Integrative Graduate Education and Research Traineeships (IGERT) Program has been established at The Ohio State University to study Molecular Engineering of Micro-Devices (MEMD). The program is designed for high-achieving doctoral students interested in combining Engineering, Chemistry, and Physics using an interdisciplinary, team-based approach. Our goal is to equip the next generation of world-class researchers, teachers, and leaders in these emerging technologies.

Because the material structure must be controlled with high definition at the 10 nm scale, novel molecular engineering and miniaturization techniques are needed. These technologies will be achieved by integrating molecular self-assembly (the bottom-up strategy) with micro/nano-manufacturing (the top-down strategy) of polymeric and ceramic materials . A unifying molecular engineering protocol will be developed and applied to the design, fabrication, and testing of devices in two major areas: (a) polymer- and ceramic-based biomedical devices (i.e. BioMEMS) , and (b) high performance ceramic sensors, sensor arrays, and membranes for transportation/environmental applications . The devices may be at the micro-scale (particles and membranes) or at larger scales with micro and nano-scale features (chips and sensors). Although a few inter-center research projects have been conducted among these four centers, they are isolated cases having limited scope. The technical breadth and complexity of this integration, to our knowledge, has not been previously attempted on this scale. A natural outgrowth will be the development of a broad-based, cross-center educational program. Our vision is to integrate the latest research developments into a practical student curriculum, and to impart to doctoral students the necessary multidisciplinary skills and global awareness needed to catalyze broader impacts on society. The key elements of the inter-center education and training program include four to five new MEMD courses (multipurpose seminar course, overview course, sensor technology, nanotechnology and/or membrane science and technology); an interdisciplinary curriculum; dedicated research at two or more centers; industry internships and internships at national laboratories; travel to national and international meetings; tours and visits to research labs in the U.S. and abroad; and a web-based dissemination plan. Management and leadership training of an interdisciplinary nature will involve major industrial interactions, with the aim of imparting a wide range of skills needed to excel in the workplace. Four major interdisciplinary centers at Ohio State —the Center for Advanced Polymer and Composite Engineering (CAPCE), the Center for Industrial Sensors and Measurements (CISM), the Center for Automotive Research (CAR), and Biomedical Engineering/MicroMD and the Florida Advanced Center for Composite Technologies at FAMU/FSU, an historically black university, are collaborating in this effort.

However, major technical challenges impede the synthesis and characterization of high-definition nanostructured materials and micro/nano-manufacturing. Progress will require close collaboration among engineers, chemists, physicists, and biologists and is one of the most interdisciplinary endeavors facing society. Multifaceted partnerships in education involving academia, government, national laboratories and industries have been slow to emerge. The vision of the proposed program is to integrate the latest research developments into the student curriculum and to help students develop skills needed to establish career in this important area. Four major interdisciplinary centers at Ohio State—CAPCE, CISM, CAR-IT, and BME (MicroMD)—propose to collaborate in this effort. Both CAPCE and CISM are NSF Centers. Collectively these four centers house more than 15M worth of state-of-the-art equipment in synthesis and characterization of polymers, ceramics and biomaterials, micro- and nano-scale manufacturing, and device/sensor fabrication and testing. Their research programs are sponsored by more than 50 companies, and their annual budgets exceed 7M from federal funding agencies, the state of Ohio, and industry. Each center currently has expertise in focused areas of materials research including polymers, ceramics, and biomaterials. In addition, a very strong faculty team is assembled for this collaborative effort. It includes 5 center directors, 3 department chairs, the Associate Dean of the College of Engineering, 2 Distinguished University Professors, 4 Chaired Professors, and 5 winners of the prestigious OSU Distinguished Scholar Award. A thematic basis will integrate new techniques of molecular self-assembly (the “bottom-up” strategy) and micro-/nano-manufacturing (the “top-down” strategy) to extend materials beyond the present realm of applications. Because the material structure must be controlled with high definition at the 10 nm scale, novel molecular engineering and miniaturization techniques will be developed. The proposed IGERT-MEMD education and training program and the ensuing interactions with industry will ensure that students learn greater workplace skills. Multidisciplinary training, interpersonal skills, and high-tech internships will be emphasized. Research collaboration and enrichment of the student training will be carried out with historically black colleges and universities. Initial efforts will build on existing collaborations between CAPCE and Florida A&M University.

Expected Contribution of IGERT to this Research Thrust Area The unifying research theme for IGERT-MEMD is the integration of nanostructured material synthesis, design and fabrication of microdevices, and applications in the biomedical and transportation/environmental fields.The breadth and uniqueness of this theme makes it impossible for any single center or academic department to consider this challenge.We propose to develop a close collaboration between four multidisciplinary research centers and industry/national laboratories to accomplish the goals. Figure 1 depicts the research and application challenges involved in developing these highly complex devices from early concept to final product.The research challenges require that new micro/nano-manufacturing techniques be combine d with advances at the frontiers of molecular engineering, depicted on the left side of the diagram.The application challenges are represented by several examples in the middle of the diagram, such as medical diagnostics and controlled drug delivery in the biomedical field, and particulate and gas sensoring and filtering in the transportation/environmental field.The development of novel protocols for manufacturing microdevices leading to multi-billion dollar markets requires extensive cooperation among the four participating centers and close collaboration with industry and national laboratories, shown on the right side of the diagram. Figure 1.Research plan for IGERT-MEMD. The expertise of the participating faculty is a key element for effective advising of IGERT fellows on specific aspects of MEMD.However, equally important is the availability of extensive and sophisticated research equipment and facilities at the four centers.In the following sections, we first briefly introduce the status and infrastructure of the centers, followed with a more in-depth description of the two research areas with two examples each.The examples illustrate the rich infrastructure available to IGERT fellows for carrying out MEMD-related research. Brief Center Introductions The NSF Center for Advanced Polymer and Composite Engineering (CAPCE) is an Industry/University Cooperative Research Center (I/UCRC) at the Ohio State University .CAPCE offers a comprehensive and well-organized research program that combines the application-oriented research of over twenty member companies with more fundamental university-based research to enhance the commercialization of advanced polymer and composite materials.The research at CAPCE concentrates on manufacturing polymeric materials via melt, powder, and reactive liquid processing and forming from sheet and bulk materials.Currently, 10 faculty and more than 25 graduate students from chemical engineering, mechanical engineering, materials science and engineering, and industrial, welding, and system engineering are involved in CAPCE sponsored research projects.A major effort during the first five years of CAPCE was instrument modernization, leading to the establishment of seven laboratory facilities valued in excess of 6 million (some unique in North American universities) in injection molding, extrusion, rheological measurement, composite manufacturing, mechanical testing, analytical characterization, and microfabrication. CAPCE was funded for Phase I on October 1, 1997 .The five-year Phase I program (1.5 million annual budget from NSF, industry, the state of Ohio , and university) will end on September 30, 2002 .Starting October 1, 2002 , CAPCE will receive a Phase II I/UCRC award for five more years.Future research efforts will be more closely linked with CISM for sensor and membrane design, with CAR-IT for automotive component development, and with BME (MicroMD) for BioMEMS applications.As part of the PHASE II plan, CAPCE will expand to include the Engineering Polymer Industrial Consortium at the University of Wisconsin-Madison and the Florida Advanced Center for Composites Technology at Florida A&M University-Florida State University, a historically black university, as out-of-state research sites. Center for Automotive Research and Intelligent Transportation (CAR-IT) is an interdisciplinary university research center established in 1991.CAR-IT conducts fundamental and applied research in five major thrust areas: Automotive Electronic Systems; Heavy Duty Vehicles; Intelligent Transportation Systems; Noise, Vibration and Dynamics; and Powertrain Systems.CAR-IT operates advanced experimental facilities that include engine and vehicle laboratories fluid mechanics and combustion research facilities, and an automotive electronics and sensors laboratory.In conjunction with CISM, CAR-IT had been involved in the testing of prototype automotive NO x sensors developed at CISM.Laboratory flow bench testing of the sensors has shown promising results, as has the preliminary engine testing.One of the primary application s of this type of sensor is in engine NO x after-treatment systems. Approximately 15 faculty, 50 graduate students and 12 permanent staff are involved in the Center research programs.The Center is supported through grants and contracts originating from the automotive industry and federal agencies.Annual expenditures of the Center for fiscal year 2001 were over 3.2 million.The Center operates an Industrial Research Consortium.Current members include: DaimlerChrysler, Honda, Fiat, Ford, General Motors, ArvinMeritor, DelphiAutomotive System, Dow Automotive, Lear, LuK, Oshkosh Truck, the Edison Welding Institute, the National Renewable Energy Laboratory, ST Microelectronics, the Transportation Research Center, Inc., the US Army TACOM/National Automotive Center, and the US Army Yuma Proving Ground.Additional research support is provided by Hyundai, Visteon, Renault, Dana, Goodyear, M agneti Marelli, Owens Corning, Bosch and the National Highway Traffic Safety Administration. The NSF Center for Industrial Sensors and Measurement (CISM) is a State /Industry/ University Cooperative Research Center (S/I/UCRC) at the Ohio State University .CISM was funded for PHASE I on April 1, 1996 .The four-year Phase I program (4.8 million) ended on March 31, 2000 .CISM was selected for a Phase II award for four more years at 6.6 million starting April 1, 2000 . Currently, 13 faculty and 16 graduate students are involved in CISM \'s research activities.The ongoing developments in micro-ceramic devices and our entry into micro polymeric devices and membrane technology have positioned CISM in the forefront of non-Silicon micro-manufacturing and in Phase II we want to further exploit and expand this position.The emphasis on non-silicon sensors at CISM sets it apart from other center in the US .Current research focuses on the development of solid-state sensors along with artificial intelligence and neural-net methodology to analyze complex gas streams.Future research efforts will be closely linked with CAPCE on developing microdevices, and with CAR-IT, BME (MicroMD), and OSCAR on developing and testing sensors for automotive, biomedical, and coal combustion environments. Over the past several years, dedicated laboratories have been established at CISM to support development of solid state sensors.These facilities, worth more than 3M, include thick film fabrication by screen printing and spin coating, hybrid micro-electronics lab for BioMEMS, an Electronic Nose along with artificial intelligence and neural-net software, wide range of electrical (dc and ac) measurement equipment, a complete sensor measurement and testing facility with capability for controlled gas flow and mixing systems, and computer-controlled data acquisition and analyses with specially written software.Bulk ceramic and polymer processing and fabrication facilities are also available for sample preparation.Under a recent grant from the Ohio Board of Regents, a laboratory for novel microfabrication methods of non-silicon materials (ceramics and polymers) is currently underway.Among other equipment, this facility will include a multi-cathode dc/rf magnetron sputtering unit (Discovery 18 by Denton Vacuum), bench-top sputtering unit for electrode preparation, photo-electrochemical setup, surface profilometer, and a bench-top tape-casting unit. Biomedical Engineering Center (BME) and Ohio MicroMD Laboratory : BME is an interdisciplinary center funded by both the College of Engineering and the Medical School at OSU nearly 20 years ago.Currently, there are 15 faculty positions and about 50 graduate students.In recent years, BME has focused its research efforts on BioMEMS (Biomedical Micro-Electro-Mechanical-Systems) and bio-molecular engineering.BME is closely linked to a newly-established research facility, the Ohio MicroMD Laboratory.MicroMD represents an ongoing 27M investment from the state of Ohio and OSU.It bring s together the technology of microelectronic fabrication with the ever-increasing ability to control biological interactions.It is a unique facility designed to integrate micro-nanofabrication to support a broad range of activities, including silicon processing for MEMS applications, and ceramics and polymer synthesis and processing.The bioprocessing line is fully enabled for production of biological components and reagent ranging from engineering nucleic acid molecules to engineered proteins to transgenic eukaryotic cells, in addition to protein semisynthesis and bioconjugate capabilities. The integration of synthesis and bioprocessing capabilities in MicroMD allows production of an unprecedentedly-broad range of hybrid device architectures, ranging from fully synthetic materials and MEMS systems to semi-and fully-biological devices.The potential applications of these devices range from conventional materials, mechanical and electronic instrumentalities to hybrid devices that interface with living systems in diagnostic, therapeutic and other applications. Research Thrust Area 1: Molecular Engineering of Polymer/Ceramic Microdevices for Biomedical Applications (Participating faculty: Castro, Epstein, Fan, Ferrari, Hansford, Koelling, Lannutti, J. Lee, S. Lee, Rathman, Sandhage, Tomasko, Verweij, B. Wang) Background The demand for high-precision miniature devices for biomedical applications had grown rapidly in recent year . Current microdevices are largely based on silicon, owing to extensive development of micro-fabrication methods by the microelectronics industry.Unfortunately, the physical and chemical properties of Si-based materials (poor impact strength/toughness, lack of optical clarity, poor biocompatibility) are not appropriate for many biomedical devices.In contrast, polymeric and ceramic materials possess a number of properties that make them attractive for such devices.Certain polymers can exhibit high toughness, optical clarity, and recyclability, whereas certain ceramics possess excellent biocompatibility, dimensional stability, and stiffness.Properly designed polymer/ceramic composites can offer optimally-tailored combinations of properties for a variety of biomedical devices.Future markets for polymer/ceramic biomedical microdevices are enormous (tens of billions of dollars) and encompass applications inlab-on-a-chip, drug delivery, tissue engineering, cell immuno-protection, protein separation, and protection against biological warfare agents and biotoxins.These structures will incorporate biological macromolecules and structures as is appropriate to their individual functions. Current polymer and ceramic membranes used in biomedical devices possess nanopores with non-uniform size distributions that make it difficult to control the passage of drugs and immuno-globulins (~30-50 nm in size) through such membranes.Non-uniform porosity also requires the use of long torturous flow paths necessitating the use of thick membranes.Nano-scaled resistance to flow in such thick membranes is high, so that high applied pressures (~1-4 MPa) are needed, which further complicates use.These membranes also show incomplete virus retention. Appreciable worldwide activity is underway to develop cost-effective methods for manufacturing polymer and ceramic microcomponents with well-controlled nanoscale (10 2 -10 0 nm) features.Polymer-based microcomponents have recently been produced by combining various top-down lithography techniques with conventional manufacturing methods (e.g., injection molding, embossing, silicone rubber casting).However, these methods yield feature sizes >_0.1 um with relatively low aspect ratios.To p -down mass production of polymeric devices with well-defined nanoscale features and high aspect ratios remains a major challenge.To date, two general approaches have been pursued to fabricate nanoscale devices: i) top-down methods (e.g., patterning with high-energy X-rays, electrons, or ion beams) and ii) bottom-up methods (e.g., directed self-assembly of nanostructures).Patterning with high-energy x-rays, ion beams, and electron beams is relatively expensive, owing to the need for significant investment in capital equipments.Although such investment may be justified for very high-throughput manufacturing of a relatively limited range of products (e.g., for Si-based memory devices or microprocessors in the IC industry), beam-based patterning cannot quickly and easily adapt to the wide variety of materials (polymers, ceramics, composites) of interest for rapidly-emerging medical applications. The broad product needs, relatively short product lifetimes, and FDA specifications for biomedical devices require versatile and cost-effective mass production methods that can be applied to a wide range of non-Si-based materials.Bottom-up self-assembly can be an inexpensive rout e to highly-ordered nanostructures with simple forms (thin films, particles, or fibers).However, self-assembly alone cannot yet yield ordered nanostructures with the precise, complicated 3D geometries needed for many biomedical devices.It is also difficult to scale-up self-assembled nanostructures without introducing significant defects. Several synthetic and biomimetic processing routes have recently yielded self-assembled ceramic structures with nanoscale features.Indeed, mesocrystalline membranes containing nanoscale pores with well-ordered configurations have been produced through the directed self-assembly of silica particles.However, the SiO 2 -based membranes produced by such bottom-up processing are not biocompatible.These specific limitations to top-down and bottom-up processing have recently been addressed in several novel processes developed at The Ohio State University and the collaborating partners.These new methods enable the development of unique hybrid (top-down + bottom-up) manufacturing protocol for mass producing precisely-designed, miniature biomedical devices comprised of biocompatible, mechanically-robust, polymer/ceramic composites. Research Plan In this research thrust, we plan to develop a unifying, cost-effective, and robust molecular engineering protocol o microdevices for biomedical applications based on: i)precise and scalable micro-/nano-patterning of polymers (top-down processing), ii)self-assembly (bottom-up processing) of nanostructured polymers or ceramics in micro-/nano-patterned environment, iii)synthesis of biological macromolecules (proteins and nucleic acids) and their orthogonal conjugation to synthetic components, and iv)novel integration of the polymer, ceramic, and biological nanostructures into functional devices that can be applied to various biomedical applications. Figure 2 shows a representative research theme of this proposed new molecular engineering protocol, along with several biomedical device application s .Novel top-down patterning methods are used to produce precise channels within polymers for the transport and/or containment of desired fluids or biomolecules.Patterning and replication methods will include i) the sacrificial layer lithography method, and ii) the nanotip array resin imprinting method.These scaleable patterning methods yield feature sizes in the range of 0.1 to 100 um with high aspect ratios.Ceramic self-assembly will be used to produce nanoporous silica structures with well-controlled p ore sizes.Such bottom-up processing will include: i) a synthetic approach utilizing amphiphilic organic molecules to direct the assembly of silica particles at liquid/liquid interfaces, and ii) a biomimetic process using polypeptides to direct the assembly of silica particles.These processes can generate silica nanostructures with pores of controlled sizes in the 1 to 100 nm range.The directed self-assembly of nanoporous structures of relatively biocompatible materials, such as hydroxyapatite and diopside, has not yet been achieved.Recently-developed processes at The Ohio State University (OSU) and the Air Force Research Laboratory (AFRL) can address these limitations.These novel reaction processes can convert nanoporous SiO 2 into CaO or MgO with the same shape and nanoscale features.This can then be further converted into biocompatible nanoporous membranes to cover the polymer nanochannels for well-controlled filtration and/or separation.Assembly of the ceramic and polymeric structures will then yield micro/nanofulidic devices that are biocompatible and mechanically robust (rigid, stable), and that possess well-controlled nanofeatures (channels, pores).Transport, biochemical and mechanical properties of these devices will be measured experimentally and modeled theoretically. Since the proposed research deals with new synergistic technologies, an interdisciplinary team has been formed that consists of experienced researchers from CAPCE, CISM, and BME at OSU,and several research laboratories in Ohio such as the Ohio MicroMD Lab, the Biotechnology Group at the Air Force Research Laboratory (AFRL, Wright Patterson Air Force Base, OH), Cleveland Clinic, and the Pharmaceutical & Medical Products Group at Battelle Laboratory.A number of polymer, ceramic, and biotech companies will also participate in this effort.In addition to new technology development, critical scientific issues associated with each step of this hybrid manufacturing protocol also need to be addressed.A variety of initiatives are underway in this research thrust, with focus on microdevices for medical diagnostics and drug delivery.The following two examples show faculty involved and their contribution. Research Example: Biochips for medical diagnostics (Castro, Epstein, Hansford, Koelling, J. Lee, S. Lee, Tomasko, B. Wang) Professor James Lee of Chemical Engineering, the Director of CAPCE, is well known for his research on advanced polymer andcomposite processing, microfabrication, and polymer characterization.Together with Professor Koelling, Associate Director of CAPCE, and Professor Castro, Manager of Composite Processing Area in CAPCE, a polymer microfabrication lab has been established at OSU based on a 2.1M grant from the Ohio Board of Regents.They have developed several low-cost top-down microfabrication methods for polymeric materials based on the combination of photolithographic techniques and novel polymer molding techniques such as micro-injection molding, micro-embossing, and reaction injection molding.With funding from NSF and NASA-Ames, and technical collaboration with several biotech companies, they are applying these new techniques to the design, fabrication and packaging of various DNA/gene chips, PCR chips, enzyme assays, and immunoassays.A CD-like microfluidic platform, under development at OSU, is shown in Figure 3.This type of device is based on a set of micro- and nano-scale transport principles, and depends heavily on high precision micro-machining and micro-processing of polymeric materials [17-18].The feature dimension varies from nanometers (for immunoisolation on cell-based chips), sub-micron (for DNA fragmentation), to micron size (for microfluidics).Professor B. Wang, Chair of Industrial Engineering Department and Director of Florida Advanced Center for Composite Technologies at Florida A&M University-Florida State University, a historically black university, will collaborate with CAPCE in the micro-fabrication area. Figure 2.Proposed low cost, robust molecular engineering protocol of microdevices for biomedical applications. Professors Hansford and Stephen Lee of the Biomedical Engineering Center lead the micro-/nano-technology activities at the Ohio MicroMD Lab.Professor Hansford is developing novel bottom-up micro-nano-fabrication techniques for polymers based ona successful surface machining and sacrificial layer technique he and Professor Ferrari developed for silicon materials.He is the Principal Investigator of a recently granted 2M DARPA research grant to develop nanofluidic platforms and to analyze the associated nanofluidic behavior.Professor Stephen Lee is an expert in protein engineering and bioconjugate chemistry, including key molecular biology, gene expression and chemical protein synthesis techniques needed to engineer proteins and hybrid structures.H e ha s successfully designed and constructed multiple molecular devices including the commercially successful Bac-to-Bac molecular cloning system, a novel class of bioactive cytokinedendritic polymer bioconjugates.He is currently developing new semisynthetic nanodeivces in his laboratory, such as power systems to convert metabolic energy to electrical power and novel low-error FET sensors for detection of biohazards. Figure 3.(a) LabCD concept and (b) a micro-machined microfluidic LabCD platform. Professor Epstein of Physics/Chemistry, the Director of Center for Materials Research, is a world known expert in the field of conductive polymers.He and his collaborators have developed many novel polymers which can be used to control and modify the electric, optical, and pH properties of solid surface.H e is currently working with Professors Hansford and L.J. Lee to apply these polymers to biochip applications.The conductive polymers can be used to modify chip surfaces in order to manipulate fluid flow (i.e. electroosmosis and electrophoresis), protein-cell binding (by change surface charge and hydrophilicity) enzymatic reactions (by fast controlling of temperature and pH value [19]), and self-assembly of polymeric and ceramic materials.Modeling of transport phenomena of biomolecules in micro-and nano-scale channels under the influence of various surface forces will be carried out by James Lee and Hansford. Professor Tomasko of Chemical Engineering, also a faculty member of CAPCE, has used supercritical fluid (SCF) technology to deliver (as opposed to remove) functional molecules and impregnate them into a polymeric surface.Supercritical fluid solvents (such as CO 2 ) have been shown to be more effective than liquid solvents for surface modification of polymers.This is due to a much higher partition coefficient (2-3 orders of magnitude) for molecules distributing to the surface from a SCF compared to a liquid and the ability of supercritical CO 2 to reversibly sell polymeric matrices and therefore allow molecules to entangle with the polymer chains near the surface.Such a technique allows the modification of surfaces with very small amounts of functional molecules (hence saving cost) and results in a more durable treatment than that obtained from simple coating alone.Research at OSU has demonstrated the ability to impregnate small molecule surfactants, polymeric surfactants, and proteins into polyolefins and acrylates.Peptidic and proteinaceous tissue/cell/antigen targeting molecules, as well as biological macromolecular therapeutics, will be generated as needed under the supervision of Professor Stephen Lee, whose laboratory has the capacity to either identify appropriate molecules from the literature and express them or to derive novel targeting elements using phage display methodology. The microdevices developed from this research initiative will be tested and evaluated at Ohio MicroMD Lab, Cleveland Clinic, and several biotech companies such as Burstein Technologies, Inc., Nanogen, and ACLARA BioScience Inc. Research Example: Biocapsules, membranes, and particles for drug delivery (Ferrari, Hansford, Lannutti, J. Lee, S. Lee, Rathman, Sandhage, Tomasko, Verweij) Professor Ferrari of Biomedical Engineering, a founder of biomedical micro/nanotechnology program at OSU, and Professor Hansford have extensive experience on the use of nanoporous membrane structures for the encapsulation of pancreatic islet cells for the treatment of type I diabetes mellitus, known as an immunoisolation biocapsule.They have extended this research into the field of controlled drug delivery through specifically engineered membranes to control molecular motion.With funding and collaborative projects for iMEDD, Inc. (a start-up company in Columbus , OH ), they are working on commercial drug delivery systems based on nanoporous membranes.Professor Rathman of Chemical Engineering, also a faculty member in CAPCE, is an expert in supramolecular templating of nano (meso) porous silica films by self-assembled surfactant aggregates.He is currently working with Professors Sandhage of Materials Science and Engineering and a faculty member of CISM, James Lee, and Hansford on a project to combine these self-assembled porous membranes for a nano- polymer and ceramic composite with applications for biocapsule and drug delivery devices.An example is shown in Figure 4 where a silica-binding protein is deposited onto the walls of a micro-patterned polymer support, and silica nanospheres are synthesized within the channels of the polymeric support via the catalytic action of silaffin-like peptides.This program combines the top-down approach of polymer microfabrication techniques from Lee and Hansford with the bottom-up synthesis of the self-assembled membranes and a transformation process developed by Sandhage that allows the direct conversion of any structure from silica into other useful ceramic oxides, such as diopside or hydroxyapatite.Professor Verweij of Ceramic Engineering, the Director of CISM, is a world expert on nanoporous membrane technologies, as well as the formulation of monodisperse, uniform nanoparticles of ceramic materials for the formulation of these nanoporous membranes at low temperatures and in complex geometries.He will contribute to the design and synthesis of ceramic membranes and capsules for controlled drug delivery. Figure 4.(a) formation of a network of silica nanospheres on the walls of the polymer, (b) nanopatterning of biocatalytically formed silica [14]. Professor Hansford is working with iMEDD on polymer microfabrication techniques for the fabrication of biodegradable polymer microparticles for drug delivery to attack the neovasculature of tumorous regions, known as the Artificial Natural Killer Cell, as shown in Figure 5 .This work is funded (2.1M) by the National Cancer Institute.Professors Hansford and James Lee are also exploring the fabrication of these uniform and precise particles for pulmonary delivery of drugs with the Biomedical Products Division of the Battelle Memorial Institute.Biological macromolecules for targeting and therapeutic activity of Artificial Natural Killers will be generated in Professor Stephen Lee \'s lab.The polymer micro particle fabrication work will take advantage of the unique polymer microfabrication facilities in the Ohio MicroMD Lab and within CAPCE.Professor Lannutti of Material Science and Engineering, a faculty member of both CISM and CAPCE, has ongoing research in the synthesis of nanocrystals of ceramic material for the reinforcing of polymer structures for biocompatible strengthening of polymeric biomaterials.He and Professor Tomasko are combining supercritical fluids technology and biomaterials to produce micro- and nano-sized particles for the drug delivery that.Professor Fan of Chemical Engineering, a Distinguished University Professor, is a world known expert in particle technology and multi-phase fluidization.He has served as a consultant for companies that produce particles and inhaled aerosols for pulmonary disease.Professor Fan will team with other faculty to study the aerodynamics and deposition of particles in inhalation technology [21].

Expected Contribution of IGERT to This Research Thrust Area The above mentioned two research examples show a clear integration between the top-down of micro-patterning and the bottom-up of molecular self-assembly.Novel biomedical microdevices with nano-scale functions for medical diagnostics and drug delivery can be realized by this combined approach.Although this work is taking place in widely scattered laboratories, a comprehensive effort to develop a sustainable manufacturing protocol integrating material synthesis, surface modification, microdevice fabrication, and clinical testing is absent.IGERT funding will provide the opportunity to achieve thisgoal because of (1) the assembly of a large group of faculty and Ph.D. students from different research centers and academic departments under a well-organized program, and (2) a close collaboration between university, national laboratories, and industry over a relatively long time period.

Wang) Background There is a continuing need for the development of rugged and reliable sensors and membranes capable of making particulate and gas measurement/filtering in harsh industrial environments found in the steel, heat treating, metal casting, glass, ceramic, pulp and paper, automotive, aerospace, utility and power industries.The application of sensor and membrane filtering technology has resulted in many benefits including improved energy efficiency, better quality, lower scrap or off-specification products, and reduced emissions.The automotive industry is an excellent example, where increased use of sensor and filter technology has led to improvements in engine performance, higher energy efficiency, and reduced pollutant emissions.Tougher feral rules will continue to push technology development further in the near future.For example, the federal Environmental Protection Agency recently approved 2007-model diesel standards to prevent as many as 8,300 premature death and 17,600 cases of acute bronchitis in children each year.This requires much-improved diesel filter and sensors, and is expected to carry a worldwide market of around 1.5 billion by 2008 (Ben Dobbin, Associated Press, February 10, 2002 ). While low temperature sensors have been commercially successful, their higher temperature counterparts have been less so.This is mainly due to problems associated with sensitivity, selectivity, stability and reproducibility at higher temperatures.The lack of unit-to-unit consistency is often due to poor control over raw materials and fabrication conditions including forming, firing, and electrode attachment.A detailed understanding of the sensing mechanisms and microstructure-property correlations is needed to exploit the full potential of existing materials, or to find new systems with improved performance.There is a clear need to combine successful models developed at different length scales (atomic to mesoscopic) into an integrated framework that can be sued to drive new research, suggest critical experiments, and guide device development. Many important sensor and membrane concepts that rely on nanoscale phenomena have been proposed.However, progress is hampered because the manufacturing is rooted in conventional ceramic processing.Progress in transportation and protection of the environment is already crucial for the current world economy, but will become even more indispensable over the long term.The future technology development should be drive n by a unifying approach yielding higher added value products, in which: functionality is derived from bottom-up atomic and molecular structure, and design optimization is stretched to its limit by application of to-down high definition manufacturing Research Plan Figure 6 shows the molecular engineering protocol proposed for this research thrust, along with example sensor and membrane microdevices from both ends of the scale.Micro-patterning methods are used to produce precise patterns and structures that form the basis of sensor/sensor arrays and membrane filters.These scaleable patterning methods can yield feature sizes ranging of 0.1 to 100 um.Ceramic self-assembly will be conducted in the selected micro-environment to generate nanoparticles and films having controlled sizes in the 1-100 nm range.Novel oxide reaction processes can produce interparticle bonding and support adhesion. Finally, assembly of these ceramic structures into sensors, sensor arrays, and membrane packages must be followed by testing of their transport properties and selectivity.Molecular level of simulations of these structure-performance characteristics will also be carried out. Since the proposed research requires knowledge and expertise of advanced material synthesis, microfabrication, device integration, characterization, and molecular modeling, and interdisciplinary team has been formed that consists of experienced researchers from CISM, CAPCE, and CAR-IT at OSU, and several research laboratories in Ohio such as NASA-Glenn and OSCAR.Both ceramic and automotive companies will also participate in this effort.A variety of initiatives are underway in this research thrust, with focus on microdevices for automotive and environmental sensing/filtering.The following two examples describe our research plan, the involved faculty, and their contributions. Figure 6.Proposed robust molecular engineering protocol of microdevices for sensor/membrane applications Research Example: Ultrafast and reliable nano-particulate sensor arrays for automotive exhaust monitoring (Akbar, Dutta, Hansford, Lannutti, Ozkan, Patton, Rizzoni, Rathman, Snyder, Verweij) In-line monitoring of the composition of exhaust gas streams in harsh environments, such as automotive and power plant applications, requires sensor materials suitable for use at temperatures >500 o C.Examples of such materials are semiconductor oxides that, due to surface absorption of 0 2 , develop back-to-back Schottky barriers between adjacent particles.The presence of these barriers leads to an activated process for electron conduction.Reaction of surface oxygen with combustible gases causes release of electrons and a decrease in electrical resistance, correlated with the concentration of the combustible gas.This is the basis for the sensing mechanism, also shown in Figure 7.Catalyst particles can be added to promote selectivity.Major improvements in response time, sensitivity, selectivity, stability, and reproducibility are needed. Figure 7.Doped Ti)2 sensing mechanism. Until recently, it was not possible to prepare dense titania layers without significant grain growth.In a number of cases the processing temperatures needed for densification were such that an anatase-to-rutile grain-growth transformation was triggered.These processing problems all leased back to the fact that, apparently, the processes of titania particle preparation and deposition led to poor packing and/or rather inhomogeneous packing structures.The challenges we are facing in particle preparation and application are: Production of homogenous dispersions of isometric doped titania particles and catalysts with 0<10 nm without any clustering (agglomeration). Application of these mixtures on insulating substrates and consolidate them at very low processing temperatures, possibly in two-dimensional structures. In our research plan for this example, dispersions of amorphous spherical titania particles in decane with 0<10 nm could be formed using modified emulsion precipitation.The particles are well isolated from each other, enabling their deposition in high-definition 2D and 3D nano-particulate arrangements.Second and subsequent phase oxides can be introduced by making a dispersion of that oxide that is compatible with the titania dispersion such that final colloid-chemical stability is not affected.This is commonly achieved in the modified emulsion precipitation process by making dispersions in apolar media in which colloidal particle stabilization is obtained by adsorbed organic molecules. Figure 8.HRTEM image of ZrO2 precursor particles, prepared through the modified emulsion precipitation method [35]. Precursor anatase is normally formed with precipitation at not-too-low pH values, while precursor rutile particles can be made by adding SnCl 4 to the solution before precipitation.The first catalyst particles studied will be Fe 2 O 3 because their synthesis with the described morphology is well established like that of inert zirconia particles, shown in Figure 8.Micron-sized patterns of nano-particles can be made on a flat insulating ( a Al 2 O 3 ) substrate by: Lithographic pre-patterning and utilizing selective wetting by the processing liquid Micro-printing or micro-dispensing techniques. Partial or complete densification of the nano-particle compacts can be achieved at near-ambient conditions by nano-localized combustion of polymers adhered to the substrate and the particles.Two-dimensional particle arrangements will be assisted by self-assembly of molecules attached to the surface and dissolved in the processing liquid.Particle adhesion to the substrate will be promoted by application of inorganic polyanion adhesives.A Pt heater will be sputtered onto the back of the thin alumina substrate, completing the design of the sensor array. In applications involving large numbers of gases, the lock and key approach to selective sensing is difficult to implement.The problem of distinguishing between CO, CO 2 , O 2 , hydrocarbons (aromatic, aliphatic and functionalized), NO, NO 2 , H 2 ) in an automobile emission exhaust is similar in principle to analyzing the specific components of a perfume, which is typically a complex mixture of vapors.We suggest a novel approach to address sensitivity, selectivity and environmentalconsiderations via a technique based on Support Vector Machines (SVM).This proceeds by directly attacking the classification problem given the available data.T h e approach is firmly based on Statistical Learning Theory, which characterized the ability to generalize knowledge learned from a given set of data to unseen data.A break through development in SVM research occurred in 1992, when the original linear algorithm was generalized to the nonlinear case by employing a Kernel trick technique, which cleverly replaced a computationally prohibitive high-dimensional calculation with a simple evaluation of a low dimension kernel function.Since 1996, several fast implementation algorithms of SVMs have been proposed, and successful applications have occurred in different areas.We will test the sensor arrays with a series of solvent vapors, CO, H 2 , and CH 4 and use the data for developing the statistical pattern recognition algorithms.Real world testing of the sensor array will be done at CAR-IT to determine CO in a V-6 engine exhaust and correlated with data obtained from an on-line gas analyzer, as we have done this in the past. Professors Akbar of Materials Science and Engineering and Dutta of Chemistry took the initiative for the NSF-funded CISM program with 6.6M total funding in the field of high temperature sensors since 1996.Professor Akbar will bring in solid state electrochemistry and Professor Dutta will perform spectroscopic measurements of sensor activity.Professor Hansford will provide micro-patterning and suspensing techniques for sensor arrays.Professor Lannutti will bring in his well-established expertise in the field of nano-compaction and densification.Professor Ozkan of Chemical Engineering, one of the leading researchers in the heterogeneous catalysis field, will provide valuable new perspective on sensor-catalyst synergy from her chemical engineering background.Professor Patton of Physics has since long collaborated with Professors Dutta and Akbar in the field of molecular and sensor array modeling.Automotive application knowledge will be brought in by Professor Rizzoni of Mechanical Engineering, the Director of CAR-IT.Professor Rathman is an expert in the surfactant chemistry which is crucial in confined particle formation and controlled consolidation.Professor Snyder of Materials Science and Engineering is one of the pioneers in the application of advanced (in-situ) X-ray diffraction methods in the study of ceramics (processing) and known world-wide for the book series he wrote on the subject.Professor Verweij recently came to OSU and has seventeen years of industrial research experience at Philips Research, Eindhoven and 9 years in academia at the University of Twente in the Netherlands .In Twente, he developed the program of the Inorganic Materials Science group into one of the largest in the world with 3M annual funding in the filed of high-definition nano-particle preparation and processing. Research Example: Supported mono-layer inorganic microporous membranes with ballistic gas transport properties (Dutta, Fan, Hansford, Patton, Rathman, Verweij, Y. Wang) Molecular engineering of monolayer microporous membranes will make it possible to select gases of interest from complex gas streams.Coupling of such membranes with sensors to make integrated microdevices will increase selectivity of gas sensors (without affecting response time) and avoid sensor poisoning , making them particularly useful for harsh environment (automotive) application. Inorganic membranes can be made hydrophobic by introducing Si-CH 3 groups into the amorphous silica structure.This makes that membranes transport is no longer affected by selective adsorption of water vapor.In addition, large improvements in flux that maintain selectivity can be expected if these membranes are made with monolayer thickness.Aside from immediate application in hydrogen production, additional applications are in: Separation of CO2 from waste streams for sequestration. Purification of contaminated air.This can be used in reduction of unwanted plant emissions, air recycling within car and aircraft cabins, residential air cleaning and devices that protect against biological and chemical weapons. Figure 9.Schematic presentation of the process of molecular sieving by diffusional transport through supported amorphous silica membranes consisting of nearly linear silica polymers. The special gas transport properties of the silica membranes are based on a connected silica polymer micro-pore structure with a typical p o re diameter in the range of 0.2-0.4 nm, see Figure 9. The need for further improvement of membrane performance is illustrated with the following example: Industrial requirements with respect to air purification systems are that they must be able to purify 600m 3 /uur at a pressure difference of 50Pa.With the present membranes this would require a membrane surface of 145,000 m 2 and hence a minimal hollow fiber membrane module size of 14.5 m 3 .The diffusional membrane flux can possibly be improved by one or two orders of magnitude by further reducing membrane thickness.However, this is likely to be insufficient for most practical applications.If the mono-layer membrane structure become s such that it resembles a wire-mesh sieve, small molecules in the gas phase are able to pass unhindered though a micropore with a flux significantly higher than for diffusion transport.This ballistic process \' is represented as F1,J in Figure 10.Larger molecules will be blocked by size-exclusion.A calculation, based on gas collision frequency leads to a much more acceptable size for the air purification module of minimally 25 cm 3 . Figure 10.Well known diagram by R.M. Barrer in which various fluxes through a microporous surface are classified.The F1,J process is, what we call, the ballistic process in which a molecule may fly through the (micro)pore with a normal gas phase velocity and leave the membrane at the other side without any loss of kinetic energy. In our research plan for this example, we propose to study the formation of monolayer microporous silica membranes by hydrolysis-condensation polymerization of organo-silicon monomers.Monomers will be selected that exhibit preferential adsorption at the interface between an apolar liquid and a think micro-machined hydrophilic supporting membrane with straight pores, filled with water.Preliminary calculations have shown that monolayer membranes that span 1 um pores should be able to withstand a mechanical pressure difference of 1 Bar.We will use microseives with a high-density arrangement of 01-10 um holes.The material thickness will be chosen as small as possible between 0.5 and 5 um to minimize Knudsen diffusion resistance in one pore.The thin supporting membrane, in turn, will be supported by a metal honeycomb frame designed to optimize gas transport and mechanical strength. Methyl-tri-ethoxy-silane (MTES) will be chosen as the initial monomer.The CH 3 group of the MTES is expected to be directed towards the apolar liquid side while the ethoxy groups are expected to be at the hydrophilic (supporting membrane) side.The reactivity and surfactant action of the MTES molecules can possibly by adjusted by ligand substitution of the CH 3 and ethoxy groups by larger groups.If needed, mixtures of molecules or co-surfactants can be added to influence the result.Formation of the two-dimensional microporous network structure will be simulated by molecular modeling techniques.Morphological characterization of the membranes will be done at the university \'s Campuswide Electron Optics Facility by transmission electron microscopy of a thin cross-section of the membrane.In addition, the presence of the supported membrane and its properties will be studied by ellipsometry.The transport properties of the membranes will be determined in the pressure-controlled dead-end mode in the temperature range of 50 to 300 0 C.To obtain more insight in to the actual mechanism of ballistic small molecule transport through the thin membrane structure, this process will be simulated by molecular dynamics techniques.These gas-selective microporous membranes will be coupled with the sensor assemblies to make the next generation of microdevices suitable for operations in harsh environments. Professors Dutta and Rathman will work together on monolayer membrane formation by combing their expertise in zeolite chemistry and supramolecular templating of nano (meso) porous silica films by self-assembled surfactant aggregates Professor Hansford will provide micro-/nano-fabrication techniques for membrane supports based on his successful surface machining and sacrificial layer technique.Professor Fan of Chemical Engineering, founder of OSCAR, is an authority in the field of particulate chemical engineering.He will provide application knowledge for the field of fossil fuel utilization.Professor Verweij is regarded as one of the world \'s \' leading experts in the field of inorganic membrane technology.He took the initiative for several European cooperations in the field of microporous membrane reactor technology for clean and energy-efficient production.Three consortium projects are currently funded by the European community at 5M level.Professor Y. Wang of Materials Science and Engineering will provide molecular modeling background for the ballistic transport process. Expected Contribution of IGERT to This Research Thrust Area These examples clearly demonstrate the need for integration of the top-down micromanufacturing and bottom-up molecular control.The first approach is needed during the patterning, electroding and nano-localized burnout of sensor substrates and membrane support structure.The second approach becomes particularly important information of two-dimensional membranes by promoting adhesion and altering the hydrophobicity of the support structure.For sensor technology, molecular control is already exploited in well-dispersed particle preparation but becomes particularly important in selective wetting and organization of two-dimensional nano-particle consolidate.The project is in its formative stage and IGERT funding will strengthen existing efforts while providing opportunities for expansion.Specific new or enhanced components of the project made possible by IGERT include (1) a large-scale comprehensive research plan form material synthesis, microdevice fabrication, to in -field testing by a group of faculty and Ph.D. students with broad interdisciplinary expertise; and (2) a close collaboration between university, national laboratories, and industry.");arrFiles[11]=new Array("4Faculty.htm","IGERT - The Ohio State University","","","SEARCH:");arrFiles[12]=new Array("4Staff.htm","IGERT - The Ohio State University","","","SEARCH: Sheik A.
