34Materials and Chemical EngineeringYasushi MurakamiProfessorBreaking new ground in materials, processes, and systems with the ultimate goal of energy self-sufficiencyDivision of Chemistry and MaterialsThe optical materials and inorganic nanofiber materials that my lab has developed are unique in the world, and they are actually being used. My current focus is energy self-sufficiency. If biomass could be dried without applying too much energy, it would be possible to utilize marine resources as well, and if electricity could be generated efficiently from heat, we would be able to convert the long wavelength range of sunlight into electricity.Professor Murakami joined the Faculty of Textile Science and Technology at Shinshu University in 1993 and took his current position in 2007. He spent ve years working as the lead researcher for the knowledge cluster creation project starting in 2007, during which time he spearheaded advanced collaboration between industry and academia. His area of research is material chemistry.A project develops into major research when a new and unprecedented vision is proposed. My hope for my students is that they will grow into researchers who can propose such visions.Outlook for researchIn the development of new materials, failure is more common than success. My goal is to foster the development of tough and resilient researchers.Outlook for students after graduationWe select only research that is truly necessary to solve society’s problems and strive to break new ground with our work.Titanium oxide nanober used as a photo catalystA highly active and long-life platinum/silica fuel cell catalystMaterials and Chemical EngineeringHisanao UsamiProfessorPhotoinduced redox reaction controlled by fine structuring of the reaction fields Division of Chemistry and MaterialsOur research targets are photoinduced reduction and oxidation controlled by fine structuring of nano-layers and their application to photo-to-chemical energy conversion and water purification. Organic dyes and metal oxide semiconductors are alternatively aligned by Langmuir-Blodgett method (photo in upper right). The dyes absorb light to be activated to their electronically excited state. The activated electron-hole pair can be separated by the layered structure and applied to the redox reactions. For scaling-up these reactions, a novel photochemical reactor with porous glass monolith has also been studied (photo in lower right).Research Associate in Shinshu University in 1992. He was promoted to full professor in 2012. His research topics are photochemistry and photocatalyst in nano- layers and microchannel reactors.Stacks of nanolayers of dye-metal oxide hybrid can be applied to promote the net redox reaction. Hybrid layers of metal oxides will be a model system of co-catalyst grafted on TiO2 photocatalyst for water oxidation and CO2 reduction. Porous glass reactor will be anticipated to be applied to water purication and solar reactor for synthesis of chemicals.Outlook for researchGraduation works in laboratories are very important to improve their aptitude to utilize the knowledge of chemistry from course works to solve scientic and technological challenge. Alumni are participating actively in the elds of chemistry, electronics and machinery.Outlook for students after graduationFabrication of nano-layred reaction eld composed of organic dyes and metal oxides.Application of porous glass photochemical reactor to hydroponic culture.Hydroponic culture of lettucePhotochemical reactor with porous glass monolith through which excitation light is delivered to the reaction site.Glass columnPorous glass monolith with photocatalystPuriedwaterlamprawwater
