Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

Short Introductions of other papers: /paper/ Komatsuna plants were grown and exposed to ammonium sulfate (((NH4)2SO4), AS) submicron particles for 16 days (22.5 µg m−3 per day) in phytotrons. The amount of particles deposited on the leaf  decreased over time, because AS particles deposited on the leaf deliquesced, allowing ions such as SO42− in the… Continue reading Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

PAPER: Fine particles on bio-composite surface. ココナツ殻由来素材の表面に微粒子を集積

Other "intro" of papers from our lab >> /tag/paper/   HIGHLIGHTS: * Physical treatment on the biocomposite increases the surface roughness. * Single bond COOH network on the treated biocomposite promotes the particle deposition. * The network reduces the particles repulsion during the deposition process. # Bio-composite(バイオコンポジット)is a composite material formed by a matrix (resin) and… Continue reading PAPER: Fine particles on bio-composite surface. ココナツ殻由来素材の表面に微粒子を集積
