親水性表面への数μmのエアロゾル液滴の沈着 Micrometer-sized aerosols/ droplets on a hydrophilic surface

Droplet generator: Ultrasonic nebulizer (1.7 MHz). Micrometer sized sprayed droplets include silica nanoparticles (average particle diameter of 145 nm). A single substrate with areas having different “level” of hydrophilicity was used as a model surface. A low-pressure analysis method (electron-microscope SEM) and ordinary (1 atm) pressure methods (Raman spectroscopy and X-ray fluorescence) analytical results indicated…

“Old” and “new” students

After three years with us, Y. Hogaki and S. Azuhata, two master-course graduates entered the industries (Hitachi Chemical 日立化成, and Daikin Industries ダイキン工業) and other two fellows (without master-thesis), Y. Asanuma and N. Yoshida, continued to the doctoral course, still with our research group. 2名が博士課程進学 >> Current Members. >> Alumni.

Prof. Lenggoro’s interview, on the new department. 化学物理工学科について

In my research group, a student and I design the thesis research theme that student want to do, together. This “design process” may take several months, but I think the students have the power they need in an era where problem setting is more important than problem solving. 研究室では、学生がやりたい卒論研究テーマについて学生と一緒に設計していきます。この「設計」が数カ月かかる作業になったりしますが、問題解決能力より課題設定能力が大事と言われる時代において求められる力を身に着けていると思います。

微粒子工学の展開:”Fast”先端材料から”Slow”農学系研究へ (Talk) From “Fast” Electronic Materials to “Slow” Agricultural Studies

農学系研究のスピードは「遅い」であった。有機的、学際的プロジェクトは、工学系学生がミクロとマクロのスケールでシステムを学び、物質のbadとgood側面を考えるための良い媒体である。 The speed of agricultural research was “slow”. An organic, interdisciplinary project is a good medium for engineering students to learn a system in micro- and macro-scales and to consider the “good” and “bad” sides of the matter.
