TUAT: Japan’s second “most-productive” university in terms of “Number of papers per academic-staff”. 教員あたりの学術論文数が国内2位(農工大)

Tokyo University of Agriculture and Technology (TUAT) is a university with many “high-research-producers”. The university has about 400 academic-staffs.

Japan’s second “most-productive” university in terms of “Number of papers per academic-staff”

UK-based QS announced the QS Asian University ranking 2018 (Oct. 2017), and TUAT ranked as the top 1% of universities in Asia. In particular, it became the second place in Japan as “the number of papers per academic-staff” which is an indicator of “research power”.

Magnetite nanoparticles have been prepared by electrooxidation of iron in water. Surface modifications have been conducted by coating the nanoparticles with silica by a one-step synthesis in dilute sodium silicate solution. The mean size of particles was approximately 10–30 nm for the uncoated particles and 9–12 nm for the coated particles. The results obtained from thermal gravimetric/differential thermal analysis (TG/DTA) revealed that the silica layer formed by the electrochemical method was stable and could serve as a protective layer. Annealing the nanoparticles at 550 °C converts magnetite into maghemite for the silica-coated particles, and it further converts the uncoated particles into hematite. The conversions cause the saturation magnetization to decrease for all samples.
