We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...
