Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

Other "intro" of papers from our lab >> /tag/paper/ Our results suggest that epicuticular wax crystals affect distribution of particles on needles. Densely distributed epicuticular wax crystals might prevent the deposition of sub-micron particles on the surfaces of needles to retain the function of stomata. 電界放出型走査電子顕微鏡(FE-SEM)によるスギ(代表的な針葉樹種)の葉表面に人工的に散布されたサブミクロンサイズの炭素系粒子の局在を調べました。気孔の機能を保持するために、密に分布されたエピクチクラワックス結晶は、気中からの微粒子の付着を防止する役割があるかもしれません。 Elucidation of the mechanism of adsorption of particles suspended in the… Continue reading Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

22 November 2012 COMSOL CONFERENCE TOKYO 2012 http://www.kesco.co.jp/conference/2012 Presenter: Masao Gen 冷却後の希釈器内における混合ガス由来のモデルエアロゾルの計測 Measurement of model aerosols derived from gas mixtures after cooling in a diluter 燃焼由来の重金属を含む粒子状物質は環境負荷の原因の一つとして懸念されている。発生ガスから粒子化は冷却ならびに希釈を経て起こるとされているが、未だに詳細なメカニズムは明らかになっていない。そこで本研究ではモデルガスから生成した粒子のオンライン計測を行った。また、ガスから粒子化へのプロセスの把握のため、流体と伝熱のシミュレーションを行い、実験結果との比較を行った。 The emission of particles involving heavy metals in combustion process is a contributor to environmental concerns. However there is little study on the mechanism by which gas-to-particle conversion occurs… Continue reading Invited to COMSOL Conference Tokyo 2012 (22 Nov.)
