Associate Professor / SHIRONITA Sayoko
Dr. Shironita is easy to talk to and familiar with us. She is a reliable teacher who will help us cordially if we have any problems with our research.In addition to the research content, the teacher talks to us.

Research Content

Materials that do not react with chemical substances are required for stable storage of chemical energy. Therefore, surface treatment of stainless steel is performed using nitrogen heat treatment and sputtering. Evaluate corrosion resistance by electrochemical measurement and use various analytical instruments to search for optimal conditions for surface treatment. Due to the high stabilization of stainless steel, it is expected to be used for stable storage of energy, specifically for current collector materials of lithium-ion cells and bipolar plates for polymer electrolyte fuel cells.

A Day in the Lab

We have English seminars that read and present English papers and general seminars that report the progress of research. At the seminar, we discuss with laboratory members and teachers. We sometimes discuss our research plan with teacher and decide on a research direction. We get along well regardless of our grade and enjoy drinking and playing sports.
