Back Cover: A Molybdenum Disulfide Nanozyme with Charge‐Enhanced Activity for Ultrasound‐Mediated Cascade‐Catalytic Tumor Ferroptosis (Angew. Chem. Int. Ed. 11/2023)

Abstract

BTO/MoS2@CA , with the integration of charge‐enhanced enzymatic activity, pH‐responsive CA release‐mediated H2O2 self‐supply, and GSH depletion, enables out‐of‐balance redox homeostasis, leading to effective tumor ferroptosis. As demonstrated by Yawei Lv, Xin Yu, Jing Liu, Chunying Chen et al. in their Research Article (e202217448), charge is one of the important contributing factors for nanozyme activity, which has not been mentioned previously.

Ultrafine Fe2C Iron Carbide Nanoclusters Trapped in Topological Carbon Defects for Efficient Electroreduction of Carbon Dioxide

“…Besides the regulation of coordination environment, the rational construction of metal-based electrocatalysts with tailored size is of great significance for achieving the targeted activity in CO 2 RR electrocatalysis. [31][32] In this context, we envisage that fabricating nanoscale iron carbide clusters cannot only expose unsaturated carbon that leads to the Normally, the CO 2 reduction reaction (CO 2 RR) on Fe-based materials is unfavorable due to the poisoning of reaction sites by CO products. By modulating the electronic structures of Fe sites via carbonization, the CO binding strength can be optimized to facilitate the CO 2 RR.…”

Transient regulation of gel properties by chemical reaction networks

“…Materials are inevitably damaged and destroyed during usage, so endowing them with good self-healing ability is essential for achieving sustainable development of materials. 22,[81][82][83][84][85] Inspired by biological systems (such as the healing of human skin, the regeneration of lizard tails, and so on), researchers have designed a series of new intelligent self-healing materials, and have detailed the healing mechanisms, preparation method, and development trends of the materials. 20,[86][87][88][89] Using CRNs to temporarily control the dynamics of covalent or coordination bonds, systems chemistry has recently shown great promise to reconcile the contradiction between the kinetic inertness and healing ability of gel materials.…”

Regulating the electronic structure of single-atom catalysts for electrochemical energy conversion

“…In particular, the Co 3 O 4 carrier modulates the unoccupied 5d state of Pt SAs by EMSI and weakens the hydrogen adsorption at Pt SAs, thus greatly improving hydrogen production. [63][64][65][66][67][68][69][70] Therefore, some strategies, e.g., adjusting the central atoms or structure of substrates, doping heteroatoms, and changing the strain, have been achieved to regulate the coordination environment of SACs. 9,[71][72][73][74] The uniform and well-dened structural characteristics of SACs are benecial for investigating the electrocatalytic mechanism.…”
