45Yuichi HirataAssociate ProfessorApplied Molecular ChemistryExamining the mystery of polymer membranes and using tiny holes in PET bottlesDepartment of Chemistry and MaterialsSynthetic resin polymer membranes, of which PET bottles are a leading example, have extremely tiny pores that allow gases to pass through them but not liquids. I am working to develop a barrier material for electronic materials that will make them 1 million times less permeable to gases. This area of research is currently garnering attention.Associate Professor Hirata took his current position in 2010 after working as a senior assistant professor at the Meiji University School of Science and Technology, as a doctoral researcher at the French National Institute for Agricultural Research, and as an assistant professor in the Faculty of Textile Science and Technology at Shinshu University. His principal areas of research include barrier lms, separation membranes, and dye chemistry.I am also researching polymers that will only allow specied substances to pass through them. This property could be leveraged to make it possible to extract only oxygen from the air, or pure water from the ocean. Medical applications are also possible, such as for dialysis.Outlook for researchIn addition to working for chemical manufacturers, graduates are active in a wide range of research domains that extends beyond any single industry.Outlook for students after graduationSalt water can be seen on the left and pure water on the right. A salinometer is being used to measure how much salt passes through the lm to the pure water side.Cellulose acetate is boiled in ammonia to examine polymer changes.Students are also engaged in the creation of membranes using surfactants.Tetsuya FujimotoAssociate ProfessorApplied Molecular ChemistryDeveloping novel organocatalysts for highly stereoselective synthesis of organic moleculesDepartment of Chemistry and MaterialsOrganic molecules sometimes come in a chiral form with an enantiotopic relationship. I am carrying out research focused primarily on the development of an asymmetrical catalyst to selectively synthesize one side of a chiral molecule. My goal in doing so is to create new catalysts that are highly selective and highly activated, that do not use rare metals, and that can be synthesized simply.Associate Professor Fujimoto rst completed a Shinshu University Graduate School of Engineering research course specializing in the study of functional polymers. His area of research is organic synthetic chemistry, and his work focuses on new methods for organic synthesis and the development of new catalysts.Expected applications include the functionalization of glycerin, a type of biomass, using the asymmetric esterication reaction and the easy supply of optically active alcohol and amine, in addition to the carbon-carbon bond-forming reaction that is important for organic synthesis.Outlook for researchGraduates have gone on to work for manufacturers of low- and high-polymer products and pharmaceuticals.Outlook for students after graduationAn asymmetric esterication solution designed based on atomic principles, and associated reactions. Esterication proceeds by dierentiating between the two symmetrical hydroxyls in the diol.A view of the lab. Numerous reagents, solvents, and glass containers are used to synthesize the target organic compounds, yielding substances whose structure can be conrmed using NMR.NNOPh2PCatalystRROHOHCatalystC6H5COCl, i -Pr2EtNRROCOC6H5OHUp to 94 % ee
