Witryna由和式可知, 共振增强状态意味着球体内外部电场都可以被共振增强, 对应于α极大值. 至此, 当球体尺寸远小于入射光波长时, 球体在准静态近似下被当作理想偶极子处理的方式是有效的, 也说明这一方式可用于计算忽略体积延迟效应时金属球与入射光的相互作用. Witryna如 图 2a 所示,Fe-Co-B-P、Fe-Co-B、Fe-Co-P、Fe-B-P、Co-B-P循环前均在20°左右出现一个弱且宽的衍射峰,表明Fe-Co-B-P和对比材料的结晶度均较低,为无定形态,意味着材料中可能存在较多缺陷,这有利于暴露更多的活性位点 ,同时,还有利于催化剂活性位点与电解液的 ...
Nanosphere - an overview ScienceDirect Topics
WitrynaThe nanospheres (size of 280-300 nm) possess uniformly spherical morphology and mesoporous structure, and well distributed Eu elements. The nanospheres show distinct fluorescent property at 615 nm for potential bio-labeling. WitrynaNanospheres can be defined as matrix-typecolloidal particlesin which a drug is entrapped, dissolved, chemically bound or adsorbed to the constituent polymer matrix, while nanocapsules are vesicular systemswith a typical core-shell structurein which the drug is mainly confined to a reservoir or within a cavity surroxmded by a polymer … mb30wp parts
