Direct Sequential Block Copolymerization of a Highly Polarity-Mismatched Monomer Pair

Yifan Tian, Xule Yang, Weijia Fan, Qiuyu Zhang

Abstract Access to smaller phase domain dimensions requires reducing the degree of polymerization, which weakens segregation and increases the importance of strong segmental incompatibility; however, the same chemical contrast can impede direct sequential block copolymerization through differences in solvent affinity. Here, we …

Incorporation of Graphdiyne‐Based sp‐Carbon Into the First Coordination Sphere of a Metal Complex for the Electrocatalysis of Nitric Oxide to Ammonia

Jiahao Ma, Jieyu Liu, Changhong Wang, Chuanqi Cheng et autres

ABSTRACT Although metal‒carbon bonds are prevalent in organometallics, integrating carbon donors alongside nitrogen, oxygen, and sulfur heteroatoms into the first coordination sphere of metal complexes poses a considerable challenge. Here, graphdiyne‐based sp‐carbon atoms are incorporated into the first coordination sphere of the …

Synergistic Dual Activation: Phenanthrenequinone-Polymer-Driven Photo-self-Fenton/Peroxydisulfate Integrated Process for Efficient Antibiotic Degradation

Penghui Dong, Junjian Xie, Guoxian Zhang, Suning Mei et autres

Abstract Antibiotic pollution poses severe environmental risks, necessitating efficient advanced degradation technologies. While photo-self-Fenton and photoactivated persulfate systems show promise, they still suffer from limitations such as the need for external additives and inefficient oxidant utilization. Herein, we develop a phenanthrenequinone-based conjugated …

Hydrophobic fluorinated superacid resins for water‐tolerant C‐C coupling to high‐density bio‐jet fuels

Junjian Xie, Xinquan Zeng, Junhao Yu, E Xiu‐tian‐feng et autres

Abstract Upgrading biomass to high‐performance fuel offers an effective solution to energy crisis and carbon neutrality goals, however, most value‐added reaction suffers from byproduct water‐induced deactivation of acid catalysts and consequent side reactions. Herein, novel hydrophobic oleophilic mesoporous fluorinated sulfonic acid resins …

Room‐Temperature Rapid Synthesis of Crystalline Ag─C Coordinated MOFs for Highly Efficient Acidic CO 2 Electroreduction

Ying Guo, Yingzhe Feng, Haojie Yang, Xiao Zhang et autres

ABSTRACT The acidic CO 2 electroreduction reaction (eCO 2 RR) shows great promise in addressing carbonation issues encountered under neutral/alkaline conditions. However, it remains challenged by low selectivity arising from high proton availability, as well as catalyst degradation due to the corrosive …

Network Pharmacology Reveals the Potential Mechanism of Ketamine in Improving Cognitive Impairment in Patients With Depression

Lei Yang, Qiuyu Zhang, Ying Zhang, Kaifang Yao et autres

Background: Ketamine may have antidepressant and anti-suicidal effects. However, the mechanism underlying ketamine-mediated improvement in cognitive impairment in patients with depression remains unclear. To improve patient cognition in depression using molecular docking and network pharmacology, we examined ketamine's key targets and identified …

Cobaltocenium-Based Metallo-polyampholyte for Friction Reduction and Antiwear via Hydration Lubrication

Shida Hou, Ping Peng, Feiran Sun, Yuankang Liu et autres

Water-based lubricants offer cost-effective, non-flammable, and environmentally friendly complements to conventional oil-based lubricant systems. However, their practical application is often limited by inadequate tribological performance. In this study, we present a cobaltocenium-based zwitterionic polymer (PGMA-Co+S-) as a high-performance additive for water-based lubrication. …
