30ProfessorFiber Materials EngineeringMutsumi KimuraDiscovering new functional materials through nanotech and realizing new functionalityby imitating the structure of living thingsDepartment of Chemistry and MaterialsI am pursuing research into high-efficiency conversion of the energy and chemicals found within living things by artificially imitating the detailed structures found in them. Specifically, my research includes the breaking down of hazardous substances found in the environment, chemical sensors that can detect trace amounts of substances, and solar panels made without silicon.Professor Kimura graduated from Tsukuba University in 1990 and from that university’s master's program in environmental science in 1992. He completed the Shinshu University Graduate School of Engineering’s doctoral research program in 1995. His area of specialization is functional material chemistry.I carry out research into environmental purication catalysts on the nano-scale, highly sensitive sensors that can detect trace amounts of chemical substances, and functional materials that allow the production of colorful solar panels. These materials are the keys to developing a society capable of sustainable growth.Outlook for researchGraduates go on to work primarily at chemical and material manufacturers, but some also work at electrical and machinery manufacturers.Outlook for students after graduationBy using materials at the nano-scale, it becomes possible to detect extremely low concentrations of gas (as part of the eort to develop articial olfactory sensors).A plant is a small chemical plant.This green solar cell imitates photosynthesis.ProfessorFiber Materials EngineeringHisanao UsamiDesign of photocatalytic reaction system with nm – µm scale architectureDepartment of Chemistry and MaterialsOur research targets are design and fabrication of photocatalytic reaction system with nm – μm scale architecture for degradation of pollutant and photochemical organic synthesis using uv-light bulb and sunlight. Photocatalytic reaction starts by absorption of a photon to produce a pair of hole and electron, which can serve as oxidation and reduction with organic compounds, respectively. We have designed a microporous glass reactor which serves as an efficient waveguide network, wide inner surface to deposit photocatalyst and a micro-channel network for efficient mass transport of substrate and products.joined Shinshu University as a research associate in 1992 and was promoted to full professor in 2012. His research topics are photocatalyst and photochemical reaction systems.Designing microporous glass reactors based on the science of photocatalyst derives intrinsic properties of each photocatalysts. The photocatalytic systems will be applied to photochemical synthesis of chemical resorces from CO2 using sunlight, which are expected to become important technologies for a sustainable society.Outlook for researchGraduate research in our laboratory supports our students to learn and utilize their knowledge of chemistry to solve scientic and technological challenges. Alumni are working in the elds of chemistry, electronics and machinery.Outlook for students after graduationTiO2 nano-tile with 3 nm thickness and 50 nm width, which can be controlled by adjusting pH, temperature and pressure.Cross sectional view of a porous glass reactor.
