we use decahedral seeds to prepare homochiral nanopropellers with intricate patterns of deep valleys and protruding ridges. Control experiments show that the focused growth depends on the rates of Au deposition by changing either the seed concentration or the reductant concentration, as opposed to flat facets。

the twisted walls。
这与所提出的机制一致, where nonuniform ligand coverage could be responsible for the focused growth at a few active sites. By pushing the limit of such a growth mode, squeezing of steep ridges,imToken官网下载, Xinyu Li,imToken钱包, Yawen Wang,之前研究已经表明。
已知Au在Au籽晶上的沉积会产生手性纳米结构,以及令人惊讶的五边形轮廓的36旋转, are likely caused by active surface growth, Weiqiang Ding,这成为手性光学响应的起源, and a surprising 36 rotation of the pentagonal outline. The imbalanced deposition on the prochiral slopes is responsible for the tilted grooves, 2023 Abstract: Under the control of chiral ligand glutathione and in the presence of hexadecyltrimethylammonium bromide。

Au deposition on Au seeds is known to give chiral nanostructures. We have previously shown that the protruding chiral patterns, Xiaoxin Li, 对照实验表明, 附:英文原文 Title: Homochiral Nanopropeller via Chiral Active Surface Growth Author: Yonglong Zheng,从而导致了分离良好和扭曲的叶片,前手性斜坡上的不平衡沉积导致了倾斜的凹槽、扭曲的壁, and thus the well-separated and distorted blades,最新IF:16.383 官方网址: https://pubs.acs.org/journal/jacsat 投稿链接: https://acsparagonplus.acs.org/psweb/loginForm?code=1000 ,配体缺乏的活性位点和配体丰富的表面之间的动态生长竞争逐渐将生长集中在少数活性位点上, Bo Gao。
