Chessadakorn Chantawong, a second-year master’s student in the Graduate School of Engineering, and Abbhiraj Singh, a fourth-year bachelor student in the Faculty of Engineering, received the Japan Society of Mechanical Engineers (JSME)’ Young Researcher Outstanding Presentation Award at the 2025 Annual Meeting of the Japan Society of Mechanical Engineers for their research presentations, “Enhanced mechanical reliability of Cu-included sintered Ag films for SiC die bonding in power electronics” and “Solid-state phase transformation of amorphous SiO2 into crystalline Si using a scanning electron microscope”, respectively.
Under the guidance of Professor Takahiro Namazu (Faculty of Engineering; specialization: nanomechanics, nanotechnology, and functional materials), Chessadakorn is conducting research on improving the reliability of nanosilver sintered joints. He discovered that adding copper particles to nanosilver paste improves both the mechanical properties and the long-term reliability of the joint. Abbhiraj has been actively researching the formation of silicon nanodots using electron beam irradiation, and has discovered that it is possible to form silicon crystalline nanodots by locally reducing silicon oxide films even at low accelerating voltages. These research results are expected to be useful in the implementation of power semiconductors and the development of new nanodevices.
Professor Namazu praised the students, saying, “I am pleased that their daily hard work has been recognized. Effort, perseverance, and enthusiasm are important for successfully completing research on technically challenging nanomaterials. I hope they will continue to work hard and lead the Nanomechatronics Laboratory at KUAS.”
