一般描述
硒粉是一种细小的粉末状物质,由硒元素的小颗粒组成,通常通过氧化硒的还原来生产。硒粉是灰色或银白色的,可能有淡红色的金属光泽。该产品以100目筛网处理,这表明颗粒较小,直径约为150微米或更小,这确保粉末细小且易于处理。
应用
硒用于 CdSe 的合成,从而通过改变半导体纳米结构的大小和形状来调节量子点太阳能电池的光响应。[1]

We herein report a facile strategy to prepare triggered degradable block copolymer nano/macro-objects, ranging from typical micelles, worms, jellyfish, and vesicles to rarely achieved spongosomes, cubosomes, and hexosomes via RAFT-mediated polymerization-induced self-assembly (PISA). The morphological transitions from a simple spherical

Surface modification of argon-plasma-pretreated poly(ethylene terephthalate) (PET) films via UV-induced graft copolymerization with acrylic acid (AAc) was carried out. Galactosylated surfaces were then obtained by coupling a galactose derivative (1-O-(6'-aminohexyl)-D-galactopyranoside) to the AAc graft chains with the aid of a
