Zhejiang Daxue xuebao. Lixue ban, 1999 用INDO方法研究了氮杂与硼杂碳笼CnX(n=59,69;X=N+,B-)的电子结构和光谱,表明CnX与C60,C70相比将发生结构畸变,氮杂碳笼比硼杂碳笼稳定,C70中靠近极附近的两种C原子易被杂原子置换.本文在对电子跃迁进行理论指认的同时,讨论了光谱红移的原因.

Segmented block copolymers based on dimerized fatty acids and poly(butylene terephthalate) [PDF]
, 1993 Segmented block copolymers based on dimerized fatty acids and poly(butylene terephthalate) (PBT) have been synthesized in the melt. Branched C36, C44 and C70 dimerized fatty acids with a low degree of unsaturation were used.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents
Advanced Functional Materials, Volume 36, Issue 26, 30 March 2026.Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Kekule Structures of Fullerene C70
Croatica Chemica Acta, 2006 Despite that, besides Buckminsterfullerene C-60, fullerene C-70 is the next most stable structure, there are considerable differences in structural properties of these two most common fullereties. The paper reports on numerous mathematical properties of the set of Kekule structures of C-70. Of over 50, 000 Kekule structures of fullerene C-70, only 2780
