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,… Continue reading 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)

Hydrophilic and hydrophobic particle layers from a single candle. 一本のろうそくから親水性と疎水性粒子膜が作れます。

Using "soot" from a candle burning, we developed two assembly routes to form hydrophilic or hydrophobic layers of carbonaceous nanoparticles. ロウソク燃焼の「煤」を用いて、親水性または疎水性を有するナノ粒子膜の作製する方法を開発。5000年前に中国で開発された、従来の「墨」技術と同じかどうか?

Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

Short Introductions of /our papers/ Komatsuna plants were grown and exposed to ammonium sulfate (((NH4)2SO4), AS) submicron particles for 16 days (22.5 µg m−3 per day) in phytotrons. The amount of particles deposited on the leaf  decreased over time, because AS particles deposited on the leaf deliquesced, allowing ions such as SO42− in the solution… Continue reading Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

An Electric Field Mill in Koganei Campus. 大気電場多点観測

学芸大学(鴨川研究室)の主催で、レンゴロ研究室は大気電場多点観測ネットワークに協力することになりました。研究の目的としては、多摩地区では落雷や降雹、ゲリラ豪雨を伴った積乱雲が数多く発生することが報告されています。これらの現象は雷雲が作り出す電場の変動と密接な関係があると考えられ、レーダー観測と合わせることで雷雲の電気的な構造を明らかにしていきます。大気電場測定装置を小金井を中心とした半径5km以内の領域に集中展開します。他の設置場所候補として、JAXA筑波宇宙センター、調布航空宇宙センター、調布飛行場があります。Organized by Gakugei University (Kamogawa laboratory), Lenggoro laboratory has cooperated within the atmospheric electric field multipoint observation network. It is reported that in Tama area many thunder clouds accompanied by lightning strikes, hail, and "quick" heavy rain are generated. These phenomena are thought to be closely related to the fluctuation of electric field which thunder cloud… Continue reading An Electric Field Mill in Koganei Campus. 大気電場多点観測
