TRANSPORT: From gas-phase to substrate. 大気中微粒子は「特殊」基板へ沈着する

植物の葉に大気中に浮遊する微粒子がどのように沈着するか?
実験室でのモデル化は、どの程度まで自然現象を再現できるか、挑戦しています。

Charged gas-phase particles can be deposited onto both sides of a substrate. 平板のウラとオモテ面に気中の帯電微粒子が付着できる

We discovered that: More hydrophilic surface, more charged particles were trapped.見出しました・・・親水性の高い表面には正に帯電された微粒子が沈着しやすい
