We are promoting studies to elucidate, predict, and control the phenomena in materials processing using laser and plasma based on the physics of the process by combining and making full use of an advanced measurement and a numerical simulation technology. Utilizing the knowledge obtained, we aim to develop a unprecedented process based on the universal truth.
To respond to technological demands for development of future society, mission of our lab is to aim at advancement in materials design and processing, baring in mind the nano-meter length scale structural/interface control at affordable MEGA-scale production. In particular, making the best of and advancing the knowledge “Plasma Materials Engineering”, we challenge to propose novel materials/processing that attain both high quality and low-cost, multi-functionality and low environmental load simultaneously. Current research targets include; control of plasma spray co-condensation for nano-composite materials production for next-generation all-solid state lithium-ion batteries, design of multi-functional interface and development of low-temperature nanoparticle-assisted sinter-joint for wide-bandgap power device, development of dissimilar material joints to proceed “multi-material” technologies.
To advance the material science research in welding/joining, 1) Clarifying the multi-scale material behaviors for visualization comprehension with atomistic approach, 2) Evolving the interfacial bonding for material science approach to advanced materials & processes, 3) Promoting the collaborative research in material mechanics process for comprehension & prediction of welding/joining phenomena. Our mission is to systematize the “Processing Metallurgy” for optimizing the welding/joining/repair/maintenance processes.
Process Metallurgy Area
Aiming to sophisticate the research of welding metallurgy, we are promoting (1) to clarify the metallurgical phenomena during welding and joining process, (2) to model it for prediction and control and (3) to improve the welded joint properties, cooperating with Welding and Joining Process Area.
For a low-carbon society, we develop biomimetic materials and manufacturing processes that weave together “engineering knowledge” and “biological knowledge” that humans and nature have accumulated. Our research consists of three main pillars; Development and application of nanomaterials that realize energy saving and energy creation through data science, Multi-materials technology that “connects and disconnects” materials with completely different properties, Nano/micro joining of electronic materials and advanced semiconductor packaging. By making full use of theory, experiments, and simulations of manufacturing process from atomic/molecular bonding to multi-materialization, we will evolve hybrid materials and manufacturing technologies that will bring about innovations in future manufacturing “Monodukuri”.
Aiming at technological innovations in processing of state-of-the-art semiconductor devices and biomaterials, we conduct research in plasma physics, plasma chemistry, and plasma-material interactions, using experiments, modeling, and numerical simulations. We perform multi-disciplinary collaborations with various research groups/institutes, including medical schools and private companies, in international research networks.
