Summary: Carbon-based nanomaterials have become widely used in industries due to their unique properties, attracting increasing attention. However, their toxicity and environmental effects, especially on aquatic biota, require careful study. This research investigated the toxicity of oxidized multi-walled carbon nanotubes (Ox-MWCNTs) on freshwater bivalves and evaluated their impacts on antioxidant defenses. The results showed a concentration-dependent response of antioxidant enzymes in the bivalves exposed to different concentrations of Ox-MWCNTs, suggesting potential risks to aquatic ecosystems and human health if contaminated animals are ingested.

Summary: Copper and its oxides are key catalyst materials in promoting hydrocarbon formation from electrocatalytic CO2 conversion. A novel method for preparing carbon-doped copper oxide catalysts through thermal treatment of copper-containing deep eutectic solvents has been described. The catalyst prepared from galactose-urea DES with copper nanoparticles and calcined for 60 minutes in air showed enhanced selectivity towards C2 and C3 products. The electrocatalytic activity of the prepared materials exhibited higher product concentrations compared to commercial CuO, with ethanol, n-propanol, and ethylene formation rates of 7.4, 6.0, and 10.4 μmol h(-1) cm(-2) at -1.7 V vs. Ag/AgCl.

Summary: This study demonstrates the use of methyltransferases in multi-enzyme cascades in vitro, including the generation of SAM in situ, to achieve regioselective diversification of THIQs. Regioselectivities of the methyltransferases depend on the group at C-1 and the presence of fluorine in different THIQs. Additionally, catechol methyltransferases used in the study show interesting dual activity.

Summary: Chitin, the most abundant amino polysaccharide in Nature, has various applications. However, eco-friendly processing of this biopolymer remains a challenge. Lytic polysaccharide monooxygenases (LPMOs) are of interest due to their ability to degrade recalcitrant chitin and cellulose. In this study, a coupled enzyme system utilizing choline oxidase from Arthrobacter globiformis for controlled H2O2 generation was investigated, demonstrating efficient LPMO-catalyzed degradation of chitin. This system offers a potential solution for choline-based bioprocessing of chitin in deep eutectic solvents.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
