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。 http://www.tuat.ac.jp/~innovate/student/collect.html#2 A reference of our Pesticide Detector (Gen et al., 2011) Continue reading Student as a project leader in a MEXT/TUAT program, 学生が研究代表者

PAPER: Measuring particles from mixed gases, ガス由来微粒子の計測

Measurement of Model Aerosols Containing Two Metal Components Formed via Cooling and Dilution Routes, Journal of Aerosol Research (2011) >> Abstract >> jstage　>> Full article, PDF. 火力発電所等の燃焼過程から生成すると考えられる混合排気ガスを実験室内で模擬した。軽金属（アルカリ）と重金属系の粉末の昇華による混合ガス成分とその後の冷却・凝縮による粒子化の挙動を計測した。 The emission of alkali and heavy metals in combustion processes is an important contributor to environmental load. We investigated experimentally in the laboratory the generation of particles from model exhaust gases derived from NaCl and CdCl2.
