PAPER: A flow system for positioning submicron particles on (40 deg. C) surface. 流体の制御で40℃の表面に微粒子を集積させた

Why 40 deg. C ?  This study considered the deposition of submicron particles on living-cell or “human-body”-modeled surface. Why a fluorescence microscope? Because other analytical tools such as SEM, work in low pressure or vacuum, which is not matched with living-system. An aerosol flow system has been constructed to mimic the delivery of particles to the air-liquid interface. A colloidal suspension of submicron fluorescent core-shell … Continue reading PAPER: A flow system for positioning submicron particles on (40 deg. C) surface. 流体の制御で40℃の表面に微粒子を集積させた

Where are our graduates now? (Lenggoro Lab TUAT)卒業生は今どこに?

In April 2018: Six students (D/M/B) graduated, after year(s) worked with us. Here is the updated data of our lab’s 40+ graduates, 11 years after the lab started. Because “diversity matter” is our lab’s keyword, the graduates’ positions also have diversity. Only one company (Toray Industries) has two graduates. Four graduates changed the job places. // Former Members (Their names)  // Doctoral Thesis. 学位(博士)論文 // Continue reading Where are our graduates now? (Lenggoro Lab TUAT)卒業生は今どこに?

PAPER: Spraying water-soluble particles to komatsuna leaves. 小松菜に水溶性微粒子を散布したら・・

Short Introductions of /our papers/


Free-access (until Dec. 1, 2017): elsevier.com

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 to be absorbed into the leaf. 葉表面に堆積した粒子の量は時間とともに減少した。サブミクロン硫酸アンモニウム(AS)粒子が葉表面に堆積し、脱離溶液中のSO42−などのイオンが葉に吸収される可能性が高い。
