Alternative solid electrolytes are the next key step in advancing lithium batteries with better thermal and chemical stability. A soft solid electrolyte, (Adpn)2LiPF6 (Adpn, adiponitrile), is synthesized and characterized that exhibits high...
Covalent organic framework atropisomers with multiple gas-triggered structural flexibilities [0.03%]
具有多重气体触发结构柔韧性的共价有机框架构象异构体
Chengjun Kang,Zhaoqiang Zhang,Shinpei Kusaka et al.
Chengjun Kang et al.
Covalent organic frameworks (COFs) are emerging crystalline porous polymers, showing great potential for applications but lacking gas-triggered flexibility. Atropisomerism was experimentally discovered in 1922 but has rarely been found in c...
Tailoring planar slip to achieve pure metal-like ductility in body-centred-cubic multi-principal element alloys [0.03%]
