43Tetsuya TanigamiAssociate ProfessorApplied Molecular ChemistryLining up sub-micron minute particles in an orderly manner to create photonic crystalsDepartment of Chemistry and MaterialsI synthesize minute particles at the sub-micron scale with identical diameters and line them up properly using electrophoretic deposition (colloid crystals). The particles have a strong electrostatic resistance and normally resist alignment. The members of my lab enjoy the challenge of researching numerous ways to overcome this issue.Associate Professor Tanigami joined the Faculty of Textile Science and Technology at Shinshu University in 1982. During his student years, he used X-rays to carry out research on the solid structure and characteristics of polymers. Currently, he is researching colloid crystals using visible light. A phenomenon common to both pursuits is Bragg reection.There is now a need for quantum computers. In order to fulll that need, it is necessary for components to allow only light of a certain wavelength to pass and to bend light at a right angle. One method for pursuing associated research is the use of colloid crystals.Outlook for researchMany graduates are employed by chemical manufacturers involved in polymers and bers.Outlook for students after graduationAn example of a material in which the color of light changes depending on the angle (polystyrene)In this research, from the right, minute particles of inorganic silica, organic polystyrene, and hydrogel are being formed into colloid crystals.2°15°30°50°2°35°50°Colloid crystalCameraLightYoshinori NishiiAssociate ProfessorApplied Molecular ChemistryUtilizing organic chemistry to solve biological phenomena: Searching for biologically active substances and developing new reactions and medicinesDepartment of Chemistry and MaterialsI use organic chemistry as a surgeon's knife to delve into life and biological phenomena. For instance, my lab successfully synthesized a natural substance with antiviral and blood platelet coagulation-inhibiting properties (that is, we synthesized a substance that is identical to a natural substance in a flask). We have also synthesized biologically active substances such as antibacterial and bactericidal substances and pheromones.Associate Professor Nishii took his current position in 2007 after serving as a doctoral researcher at the University of Pittsburgh and participating in the Special Postdoctorate Research Program at RIKEN. His principal areas of research include organic chemistry for natural substances, organic synthetic chemistry, and organic reactions.Exciting potential applications made possible by examination at the molecular level include development of medications that learn from natural substances, development of medicinal treatments for previously untreatable diseases, treatments for crop diseases, capture of harmful organisms using pheromones, and control of valuable organisms through the use of pheromones.Outlook for researchMost graduates are employed by pharmaceutical and chemical manufacturers. They are active in a wide range of research domains throughout society.Outlook for students after graduationMy lab has been successful in synthesizing several natural substances with antiviral and anti-HIV properties as well as blood platelet coagulation-inhibiting properties.OOOMeOMeOOOOOMeOMeOOMeOWe are conducting R&D work to create a bactericidal substance to help farmers deal with a disease that aects the trunks of pear and apple trees.We are also involved in research to uncover sh pheromones and explain their molecular structure and the relationship between structure and activity.
