Research Topics
Analysis of fine particles using a temporally and spatially resolved inductively coupled plasma optical emission spectroscopy
By focusing on the emission processes of particles within plasma and capturing these processes with temporally and spatially resolved measurements, we are developing an ICP-OES system that enables particle analyses-such as particle size distribution measurement and structural characterization?that were previously unattainable with conventional instruments.
Examples of Applications: Analysis of functional nanomaterials, Rapid and high-precision measurement of microplastics in liquids
Elucidating plasma-catalyst interactions and developing advanced technologies for environmental control and energy conversion
Purification of hazardous environmental pollutants (VOC, NOx, CO)
Ammonia synthesis and CO? utilization
Development of novel catalyst preparation methods using plasma
Development of multiscale environmental control technologies based on plasma discharges
By combining experimental and simulation approaches, we precisely visualize plasma discharge dynamics and reaction product formation, and translate these findings into environmental applications. Our work especially targets multiscale environmental control-such as advanced airflow manipulation and next-generation CO? conversion-through the integration of electrical engineering and fluid dynamics.
Development of photocatalyst-based technologies for environmental purification
In the field of photocatalytic water purification, we are especially advancing research related to drinking-water treatment. Beyond fundamental studies on the photocatalytic removal of water contaminants, we also conduct on-site investigations in infrastructure?limited regions of developing countries to evaluate the practical applicability of photocatalysts in real environments.
Development of environmentally friendly manufacturing processes based on microscale reaction fields
We are advancing application development for conductive yarn produced by silver plating nylon fibers, targeting uses such as wearable devices and signal cables. Conventional plating processes generate substantial volumes of waste solution, posing a major barrier to production scale-up. AIST’s femtoreactor-based plating technology overcomes this limitation by applying plating reagents directly onto the yarn through electrospray, thereby eliminating waste solution entirely. This method enables roll-to-roll continuous processing, including catalyst activation, silver film growth, and subsequent heating and drying.
Development of nanomaterials for environmental applications
Development of nanomaterials and nanoporous/membrane materials-such as graphene, carbon quantum dots, and mesoporous silica-and their applications for reducing environmental risks.
