Summary: In this study, the effects of IVA-group (C, Si, and Ge) atom doping on the structural, electronic and magnetic properties of bismuthene monolayer were investigated using first-principles calculations. It was found that C and Si doping can induce significant magnetism, either in the form of half-metallic or magnetic semiconductor characters. On the other hand, Ge doping metallizes the bismuthene monolayer. These findings suggest that C and Si doping can be an efficient approach to functionalize non-magnetic bismuthene monolayer, while Ge doping can introduce metallicity. This expands the family of 2D d(0) magnetic materials for spintronic applications.

Summary: This study demonstrates a bimetallic ion co-catalyzed electrochemical glucose detection by introducing Co(II) and Cu(II) into an alkaline solution. By using nitrogen-doped carbon nanotubes loaded on carbon cloth as the working electrode, the system achieves high sensitivity, low detection limit, good selectivity, and stability. Through systematic electrochemical and structural analysis, the mechanism of Co(II) and Cu(II) co-catalysis in glucose detection is elucidated.

Summary: An innovative strategy was developed in this paper to construct a well-aligned nitrogen-doped carbon nanotube array electrode integrated with multiple electrocatalytically active components for the hydrogen evolution reaction. Through various characterizations and density functional theory calculations, it was found that synergistic coupling interactions exist among NCNTs, CoSAs, Co, and MC, contributing to the enhanced HER performance.

Summary: The integration of heteroatom doped carbon nanotubes and cobalt phosphide through simultaneous phosphorization and carbonization method demonstrates an effective bifuctional oxygen reduction and evolution catalysis. The in-situ generated Co2P weakens the catalytic graphitization effect of metallic Co during carbonization, leading to the formation of more pyridinic-N species. The resultant Co2P/doped-CNTs catalyst shows outstanding ORR and OER performances, making it a promising air-cathode catalyst for rechargeable zinc-air batteries.

Summary: Research efforts to develop an effective soot oxidation catalyst have increased due to the awareness of the harmful effect of soot particles. This study optimized the potassium loading in the ferrierites to develop a cheap and environmentally friendly catalyst. It was found that potassium doping enhanced the catalyst's activity, while the effect of nitric oxide depended on the presence of potassium and the formation of nitrate species on the catalyst's surface.

Summary: An artificial nanozyme N-CNTs@Co with efficient oxidase-mimicking activity was developed in this study, showing a higher activity compared to iron-centered nanomaterials. It can catalyze oxygen to produce reactive oxygen species, leading to a favorable antibacterial effect against Staphylococcus aureus and Escherichia coli. The nanozyme exhibited high antibacterial efficiency without the development of resistance in bacteria and was further confirmed in wound healing experiments in vivo.

Summary: Researchers have proposed a unique Co-based catalyst by utilizing tubular-structured N-doped carbon substrates derived from dicyandiamide to confine Co nanoparticles, forming N-doped carbon nanotubes (CNT) with bamboo-like morphology. This CoCNT catalyst exhibits significantly higher catalytic activities than Co3O4 for activating monopersulfate (MNP) to degrade BPA.

Summary: The selective hydrogenation of nitrobenzene to aniline with formic acid over carbon-based metal-free catalysts was achieved. Excellent catalytic performance was observed using a catalyst prepared at 900 degrees C. This superior performance was attributed to the synergistic effect between graphitic nitrogen and pyridinic nitrogen.

Summary: Mechanical stacking of two dissimilar materials can lead to unexpected changes in behavior of heterostructures. A study of the heterostructure formed by the topological crystalline insulator Pb0.24Sn0.76Te and graphene reveals the formation of a 2D electron gas due to the contact between a polar and a nonpolar surface. The study also observes spin-momentum locking at lower temperatures that transitions to regular spin channel transport around 40K.

Summary: In this study, N-doped Co/graphite C composites were successfully fabricated, showing high wave absorption performance and lightweight characteristics. By investigating the effects of phase composition and morphology on electromagnetic parameters and absorption performance, it was found that the graphite C content was higher than the Co content, resulting in a larger contribution of dielectric loss to energy dissipation.

Summary: A simple method for the direct carboxylation of resorcinols, phenols, and indoles has been reported. The use of supercritical carbon dioxide as an electrophile and solvent under basic conditions yields moderate to high amounts of products. This method eliminates the need for solvents and metals, and avoids the cumbersome exclusion of air or water.
