Main disciplines: electrochemistry, analytical chemistry. Current research: lead-free solder plating, carbon-nanotubecomposite plating, and other plating technologies.Arai Laboratory is exploring a new world of plating technology for micro-and nano-size metal processing of new nanometaland metal-composite materials. Our lab is committed to the development of new functional materials for rechargeable battery electrodes vital to renewable energy systems, low-power and high-definition displays, low-wear coatings, high-performance heat dissipation, and other advanced applications, and to joint research with business and industry for their implementation.Plating technology is highly prized both by general electronics companies and companies specialized in plating. Graduates accordingly enjoy a wealth of employment opportunities in companies producing consumer devices, appliances, and componentsas well as chemical manufacturers.
