PAPER: Effect of water-soluble particles on the growth of plants (2 years)…植物に水溶性微粒子を与えていたら?

JOURNAL: Atmospheric Environment (2014)
http://www.sciencedirect.com/science/article/pii/S1352231014000405

Effects of 2-years exposure to (sub-micron) ammonium sulfate particles on growth and gas exchange rates of Fagus crenata (ブナ), Castanopsis sieboldii (スダジイ), Larix kaempferi (唐松) and Cryptomeria japonica (スギ) seedlings

•No significant effect of the particles on growth was observed after 2 years.
•Net photosynthetic rates of 3 species were not significantly changed.
•Net photosynthesis of Cryptomeria japonica was relatively sensitive to (NH4)2SO4.
•Both increase and reduction in net photosynthetic rate were observed in C. japonica.

4種類の植物のうち、スギの光合成速度は硫酸アンモニアの散布に影響を受けていることを見出した。

Four Japanese forest tree species were exposed to submicrometer (NH4)2SO4 particles.

Student as a project leader in a MEXT/TUAT program, 学生が研究代表者

Masao Gen, a doctoral student got a grant for his project on advancing a sensor technology to detect pesticide on-site. Sponsor = Innovation Advancement Organization (IAO), based on a TUAT/MEXT project.
博士課程後期の学生(玄)が申請した研究プロジェクトが採択されました。
The program includes few-days training at SRI (Stanford Research Institute, California) and Cornell University.

[イノベーション推進機構より]
本プロジェクトは、文部科学省実践型研究リーダー養成事業「ニーズ展開実践型高度研究人材養成モデル化事業」の一環として、博士学生に対して専門分野の枠を越えた研究活動、インターンシップ、並びに産業界との連携を包括的に支援、促進することによって、事前学習で習得した知識や技術を実践し、研究リーダーに求められる能力、資質を磨いていくことを目的としています。博士後期課程学生については、研究代表者として自ら研究チームを組織し、企業等の課題を解決できる企画・提案を実践していくとともに、その後共同研究等に発展することを奨励することとし、これに必要な経費を支援します。

TRANSPORT AND ASSEMBLY OF LIQUID-PHASE NANOPARTICLES VIA GAS-PHASE (in pdf)

An open article, by Wuled Lenggoro (2008, 2009)

* Possible applications
– For Environment & Energy: Selective-deposition method for liquid-phase nanoparticle
– For Healthcare – Measuring the non-spherical nanoparticles in the gas-phase

* Potential impact on the environment :
– Development of the “world-first” and “the only” thermal analysis method for nanoparticle
– Direct assembly method of nanoparticle layer with high-crystallinity
– Direct-patterning of nanoparticle without using a vacuum system

* Expected impact on society
