Open-shell character based theoretical design of nonlinear optical materials in future photonics and of singlet ssion materials in highly ecient organic solar cellsChallenge to create a "Bio-Inspired Chemical Engineering“ by using nano- "Inter-Face" of liposome membrane (self-assembly system) as a platform of molecular recognition / conversion.(left) Burning methane hydrate, (right) Single crystal of structure-I hydrate11Department of Materials Engineering Sciencedimensional tissues from individuall cells, and design of biocidal materials and inactivation kinetics under heterogeneous systems.Collaborative Chairs/Area of Solar Energy Chemistry■Prof.：Takayuki HIRAI (Add.)■Assoc.Prof.：Yasuhiro SHIRAISHI (Add.)The Environmental Photochemical Engineering Group has the aim of advancing the research that will resolve the problems concerning energy resources and environmental pollution through the use of solar energy. This group researches the revolu-tionary technologies that use photochemical and pho-tocatalytic reactions towards the selective conversion of organic materials, development of uorescent and colorimetric chemosensors and probes for selective detection of hazardous ionic species and metal cations, as well as the development of novel nano-structured photofunctional materials.
