29ProfessorFiber 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 UsamiPhotocatalytic Reaction SystemsSupported on Fibers and BeadsDepartment of Chemistry and MaterialsOur research topics are photocatalysts and photochemical reactors for controlled photocatalytic oxidation of aromatic compounds and photodecomposition of impurity in water. Photocatalyst nano-hybrids for the reactions are designed and fabricated by the Langmuir-Blodgett (LB) process and observed by waveguide spectroscopy. We developed a novel photochemical reactor with a network of light guide to deliver excitation light and microchannel to transfer substrate to each photocatalyst. Partial oxidation of benzene, water purification and self-cleaning textiles have been studied as some applications of the photocatalytic reaction systems.Research Associate in Shinshu University in 1992. Full professor in 2012. His research topics are photocatalyst, photo-catalytic microchannel reactors and functional textiles.Our photocatalytic reaction system has been applied to ecient organic photo-redox reactions, and will hopefully be applied to photocatalytic reactions to produce chemical resources from H2O and CO2 as an articial photosynthesis in the coming future.Outlook for researchResearch work in our laboratory has raised problem-solving ability of students, who work for companies in the elds of chemistry, chemical plant, electronics and machinery after graduating. Outlook for students after graduationLangmuir-Blodgett processNano-complex lm of soaps and ions are transferred onto the glass plate to fabricate nano-lm of hybrid photocatalyst.Photocatalyst particles on textilePhotocatalyst particles are deposited on protection coating of each berA photocatalyst reactor applied to an incubation plant of lettucePhotocatalytic reactor with a network of light guide coated with photocatalyst
