Summary: This study reports a highly efficient three-dimensional Co-N-C nanocuboids catalyst synthesized through co-pyrolysis of cobalt benzimidazole frameworks and graphitic carbon nitride (g-C3N4). The distinct porous nanocuboids and g-C3N4 play a vital role in improving the oxygen reduction reaction (ORR) performance by fully exposing Co-N active sites, increasing the electron-transfer efficiency, and facilitating the mass transport. The CoN/CNCs-800 catalyst exhibits superior catalytic performance towards the ORR, with values close to the standard of commercial Pt/C. Evaluation: 8

Summary: In this study, HaGST-8 was successfully immobilized on glutaraldehyde-activated APTES functionalized silica nanoparticles to form SiAPT-HaGST-8 nano-conjugates, which showed higher specific activity compared to free HaGST-8. The pH range for activity of the nano-conjugates was extended from 8.0 to 9.0, while the free enzyme had a pH optimum of 9.0. Both forms of the enzyme had an optimum temperature of 30 degrees C, with improved stability for the nano-conjugates lasting 10 days longer than the free enzyme. These findings suggest the potential use of silica nanoparticle-based systems for stable enzyme conjugation and effective removal of pesticides from aqueous media.

Summary: In this study, Mg and cellulose nanocrystals were doped into zinc oxide nanoparticles to synthesize products with efficient photocatalytic and bactericidal activities. Various characterization techniques were used to analyze the doped nanostructures, which showed optimal performance in basic medium and significant bactericidal efficacy against bacteria, particularly G +ve strains. Molecular docking studies suggested the potential inhibitory effects of the CNC-doped ZnO nanocomposites against beta-lactamase, DHFR, and FabI.

Summary: The cooperation of biocatalysis and chemocatalysis in a catalytic cascade reaction has been widely studied. However, practical applications are hindered by enzyme fragility, poor compatibility between carriers and enzymes, and limited catalytic efficiency. In this study, a biomimetic cascade nanoreactor (GOx@COFs@Os) was developed, integrating glucose oxidase (GOx) and Os nanozyme with covalent organic framework (COF) capsules. The GOx@COFs@Os capsule provided a spacious microenvironment to retain GOx activity and protect it from incompatible environments. The COF capsule also improved substrate affinity and mass transfer efficiency, resulting in significantly improved catalytic efficiency compared to the free cascade system. Moreover, the biomimetic cascade capsule was successfully used for glucose monitoring, glutathione sensing, and bisphenol S detection. This strategy provides a new avenue for improving biocatalytic cascade performance and expanding its applications in various fields.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
