Iinoya Award to a student (30th. Symposium on Aerosol). 院生が学会賞受賞

Iinoya Award 2013 for Masao Gen
Doctoral student: MASAO GEN got the 2013 IINOYA AWARD
during 30th SYMPOSIUM ON AEROSOL SCIENCE & TECHNOLOGY (held in Kyoto Univ.)
(Supplementary prize = cash prize of 100,000 Yen)


“Development of a portable sensor system based on aerosol particles to detect pesticide residues”


(東京農工大学・大学院博士後期課程)玄 大雄

The award selection was based from a “special session” (5 min. presentation and more than 10 min. Q/A). This session is the only session running; few hundred attendees were the judges. Not only graduate students, but senior researchers also join this session. 【井伊谷賞】ほとんどのシンポジウム参加者が審査員..特別セッションでの優れた発表を対象.エアロゾルに関する萌芽的な研究,問題点の指摘,新しい分野の開拓,未来志向の夢のある話題など,学会の発展・活性化に寄与するものについて,遊びとゆとりの気持ちを持って発表.(エアロゾルとは、気相中に浮遊する固体または液体)
