The electrochemical oxygen evolution reaction (OER) by efficient catalysts is a crucial step for the conversion of renewable energy into hydrogen fuel, in which surface/near‐surface engineering has been recognized as an effective strategy for enhancing the intrinsic activities of the OER electrocatalysts. Herein, a facile quenching approach is demonstrated that can simultaneously enable the required...
Chemically robust single‐molecule magnets (SMMs) with sufficiently high blocking temperatures TB are among the key building blocks for the realization of molecular spintronic or quantum computing devices. Such device applications require access to the magnetic system of a SMM molecule by means of electronic transport, which primarily depends on the interaction of magnetic orbitals with the electronic...

Three‐dimensional spirobifluorene‐based carbiyne nanospheres (SBFCY‐NSs) are prepared by Jinchong Xiao, Jianjiang He, Changshui Huang, and co‐workers in article number 2106328. The rationally designed chemical structure contributes to the formation of an ion diffusion pathway protected by a robust solid electrolyte interface film in a lithium ion battery.
Fused‐ring electron donors boost the efficiency of organic solar cells (OSCs), but they suffer from high cost and low yield for their large synthetic complexity (SC > 30%). Herein, the authors develop a series of simple non‐fused‐ring electron donors, PF1 and PF2, which alternately consist of furan‐3‐carboxylate and 2,2′‐bithiophene. Note that PF1 and PF2 present very small SC of 9.7% for their...
Transition‐metal oxides with a strain effect have attracted immense interest as cathode materials for fuel cells. However, owing to the introduction of heterostructures, substrates, or a large number of defects during the synthesis of strain‐bearing catalysts, not only is the structure–activity relationship complicated but also their performance is mediocre. In this study, a mode of strain introduction...
Organic molecular catalysts have received great attention as they have the merits of well‐controlled molecular structures for the development of catalytic chemistry. Herein, the electronic distribution of active sites is regulated by asymmetrically introducing S‐heterocycle on one side of the molecular core. As a result, the asymmetric as‐PYT and as‐BNT show higher oxygen reduction performance than...
Li metal is regarded as a promising anode for high‐energy‐density Li batteries, while the limited cycle life and fast capacity decay caused by notorious Li dendrite growth seriously impedes its application.

Metal‐free carbon nanozymes could be promising with the unique features of intrinsic catalytic ability, structure diversity, and strong tolerance to acidic/alkaline media. However, to date, the study of metal‐free carbon nanozymes fell far behind metal‐based nanomaterials, in which, the majority reported much more peroxidase‐like activity than other enzyme‐mimicking behavior (e.g., oxidase). Thus,...
