Through these efforts, we arechallenging the frontier of molecular integration chemistry.Outlook for students after graduationOutlook for researchI am also researching polymers that will onlyallow specified substances to pass throughthem. This property could be leveraged tomake it possible to extract only oxygen fromthe air, or pure water from the ocean.Medical applications are also possible, suchas for dialysis.Outlook for students after graduationadditionInchemicalto workingmanufacturers, graduates are active in a widerange ofresearch domains that extendsbeyond any single industry.Department ofChemistry and MaterialsDepartment ofChemistry and MaterialsIn 2020, he moved to ShinshuUniversity as an assistantprofessor.currentresearch interests include theself-assembly of amphiphiliccopolymersthefunctionaldevelopment ofpolymerforbiomedical applications.Associate Professor Hirata took hiscurrent position in 2010 after workingas a senior assistant professor at theMeiji University School of Science andTechnology, as a doctoral researcherInstitute forat the French NationalAgricultural Research, and as anassistant professor in the Faculty ofTextile Science and Technology atShinshu University. His principal areasfilms,ofdyeseparation membranes,chemistry.I try to provide an environment that will not only helpthem acquire experimental methods, logical thinking andpresentation skills, but also help them build their ownunique strengths that others do not have. I hope that theywill become active members of society.Hisandmaterialsresearch include barrierandCell-sized giant vesicles based on the self-assembly of amphiphilic block copolymersAn illustration of liposomes embedded artificial channels based on block copolymersSalt water can be seen on the left and pure water on the right.

However, thefabrication of desired molecular assemblies and control of the size of theseassemblies is difficult in practice. In our lab, we design various polymers andclarify how they self-assemble using quantum beams such as X-rays andneutrons, and electron microscopy, in order to develop methods for controllingthe structure and size of molecular assemblies. We are also investigating thefunctions that are expressed by the organization of the polymers. Furthermore,we are developing nano-bio materials such as biocatalytic reactors, artificial cells,and artificial molecular channels using molecular assemblies.Synthetic resin polymer membranes, of which PET bottlesare a leading example, have extremely tiny pores that allowgases to pass through them but not liquids. I am working todevelop a barrier material for electronic materials that willmake them 1 million times less permeable to gases. Thisarea of research is currently garnering attention.forDesign, understanding, and applications of macromolecular assembliesExamining the mystery of polymer membranes and using tiny holes in PET bottles
