【医療機器】40℃の表面に気中微粒子を沈着させた流体制御 Can aerosol particles move/deposit, from 25 to 40 ℃ surface?

閉鎖空間における沈着を考慮したエアロゾルフローシステムを構築した。沈着効率が悪い従来法に代わって本手法を気液界面細胞曝露に応用できれば有用である。An aerosol flow system has been constructed to mimic the delivery of particles to the air-liquid interface. Potentially be applied for the deposition and analysis of submicron particles on various types of substrate without the need for vacuum imaging analysis..

【環境計測技術】表面電位顕微鏡で大気中から捕集した粒子の帯電状態を調べたCharging state of particles collected from the air by K-F Microscope.

呼吸により人体に入る微粒子の帯電状態が注目された。本研究では大気中に浮遊する微粒子の帯電状態を評価できる手法を考案。The importance of electrostatic charging state to particle deposition in the human airways has been suggested. We developed a measurement method of electrostatic charging state of individual ambient aerosol particles

【環境技術】薄板の裏側まで微粒子が沈着？Are the particles deposited to the back of a sheet?

Simultaneous deposition of submicron aerosols onto both surfaces of a plate substrate by electrostatic forces We demonstrate one-step deposition of submicrometer-sized particles suspended in the gas-phase onto a plate type substrate using an electrostatic-assisted spray system. The particles were deposited on plate-type metallic surfaces, on both front and rear sides of the substrate. This “both-side”…
