37ProfessorFunctional Polymer ScienceMasahiro SuzukiCreating gels from numerous liquids throughout the world and investigating a wide array of applications for supramolecular gelsDepartment of Chemistry and MaterialsI am carrying out research into the development and application of low-molecular-weight gelling agents for gelling such liquids as oils, organic solutions, and water solutions. There is high demand for low-molecular-weight gelling agents in many fields, including oil-processing agents, cosmetics, medical and pharmaceutical applications, foods, writing supplies, paints and inks, electronic devices, and LCDs.Professor Suzuki took his current position in 2015 after working as an assistant professor and associate professor at the Shinshu University Interdisciplinary Graduate School of Science and Technology. His principal areas of research include low-molecular-weight gelling agents, functional polymer materials, and articial photosynthesis.Much research into applications for these materials focuses on low-molecular-weight gelling agents because they form nanobers within supramolecular gels. It is expected that low-molecular-weight gelling agents will permeate daily life in much the same way that polymers have.Outlook for researchGraduates are primarily employed by chemical manufacturers. Their skills as chemical researchers enable them to nd work in a wide variety of elds.Outlook for students after graduationA nano-structure formed in a supramolecular gel by a low-molecular-weight gelling agent, the gel electrolyte of a dye-sensitive solar cell, TiO2 cast production, and application as a cell-culture substrateSupermolecular gels formed from organic solutions using an L-amino acid-based low-molecular-weight gelling agent. We have created solid gels that do not fall out, even when held upside-down.Supermolecular gels from organic solutionsAcetoneSilicon oilEthanolTolueneNitrobenzeneGelling agent nano structureTiO2 nano berCulturing of broblastsDye sensitive solar cellSupramolecular gelFunctional Polymer ScienceNecklace-shaped supramolecules and cellulose/chitin nano-whiskersDepartment of Chemistry and MaterialsI am pursuing two principal areas of research. The first involves utilization of necklace-shaped supramolecules called polyrotaxanes in order to develop functional materials such as gels, fibers, and films through chemical modification. The second involves applications of nano-whiskers, that is, rod-like microcrystal particles of cellulose obtained primarily from trees and plants and those of chitin from crab and shrimp shells for use as reinforced nanocomposites.Jun ArakiAssociate ProfessorAssociate Professor Araki took his current position in 2012 after working as a JST-CREST postdoc researcher, a technical advisor to Advanced Softmaterials Inc., and an assistant professor under the Shinshu University Young Researchers Empowerment Project. His areas of specialization include supramolecular chemistry and polysaccharide chemistry.Polyrotaxane and cellulose/chitin nano-whiskers are both materials with diverse future potential. These carbohydrate-based, eco-friendly, and biodegradable components will nd wide application in society.Outlook for researchGraduates are employed primarily by chemical and material manufacturers.Outlook for students after graduationA certain polyrotaxane derivative, that is, a nano-sized necklace molecule with a width of 1 nanometer, can be used to form a exible lm that has been utilized to paint cell phones.Cellulose nano-whiskers from plants (left). These nano-sized bers have an elastic modulus higher than that of steel. They can form a liquid crystal that shows vivid birefringence between crossed polarizers (right).
