35Fiber Materials EngineeringMicrowave chemistryDepartment of Chemistry and MaterialsI am interested in creating and elucidating the physical properties of new materials using microwave irradiation. Microwave irradiation exploits "electric waves" in many everyday communications applications including terrestrial radio and TV, satellite broadcasting, cell-phones and Wi-Fi wireless LAN. These electric waves have also proven useful for a variety of other purposes, including most commonly cooking with household microwave ovens. My research goes one step further: by recognizing that electric waves, when used in cooking, ultimately change food's chemical properties, I am able to harness that power over a wide realm of chemistry applications.An image of natural allophane made using a scanning electron microscope. This material is found in great quantities in soil formed from volcanic ash and can break down endocrine disruptors at room temperature, under normal pressure conditions, and in the absence of light.A cutaway view of an allophane ball consisting of an allophane core surrounded by clay (left) and after sintering using microwaves (right).12mmTokihiro TakizawaAssistant ProfessorAssistant Professor Takizawa graduated from the Functional Polymer Science Course in the Faculty of Textile Science and Technology at Shinshu University. He took his current position after working in the Faculty as a research associate and assistant professor. His area of interest is general material properties.I carry out research based on the principle of thinking for oneself. By leveraging the research lab as a place for training, I empower graduates to respond appropriately to the demands that will be made of them in the real world.Outlook for researchGraduates develop into personnel who can proactively and specically propose processes (methods of making things) and systems (ways of using things).Outlook for students after graduationMaterials dissolve when cooledGenerally, materials dissolve by heating and/or adding solvents. HOWEVER, these material dissolve by cooling. Fibers and particles can be easily prepared.3D engineered tissue composed of cells and proteinsBy arranging cells (20-50 mm in diameter), various 3D tissues can be constructed. A new way to “Tissue Engineering”.Superhydrophobic nonwovens prepared from only amino acidsThe challenge is to reproduce the superhydrophobicity of lotus leaves without uorine, using just biocomponents.Fiber Materials EngineeringCreation of safe/secure materials from natural compounds for bio/environmental applicationsDepartment of Chemistry and MaterialsSafety and security are very important properties for medical and environmental materials. However, most materials used in biomedical situations are synthesized from oils, so developing truly safe and secure materials from bio-derived components is imperative. We are creating novel functional materials for use in biomedical and environmental applications by chemically-modifying natural compounds with good safety and security properties and then engineering and processing them appropriately. Hiroaki YoshidaAssistant ProfessorAfter completion of PhD work at Osaka University (2011), Prof. Yoshida worked as a researcher at the Georgia Institute of Technology and Osaka University before taking his current position (2014). Professional interests: Polymer Chemistry and Materials, Biomaterials.Developing novel functional materials, such as biomaterials for serious diseases and adsorption/separation materials for environmental pollution is essential to solve general problems in society today. As well, nding new materials is denitely linked to nding a new usage, and to design and develop materials to meet future challenges.Outlook for researchI believe students can choose a variety of career paths after graduation because of their wide knowledge and experience in various elds such as chemistry, biology and material science & engineering.Outlook for students after graduation
