Electrosynthesis of Organonitrogen Compounds via Hydroxylamine-Mediated Cascade Reactions.

Hydroxylamine (NH2OH) is a key intermediate in the formation of numerous high value-added organonitrogen compounds. The traditional synthesis of NH2OH requires the use of precious metals under high temperature conditions, which leads to high cost, high energy consumption, and environmental pollution. The NH2OH-mediated cascade reaction integrates the electrochemical synthesis of NH2OH and the chemical synthesis of organonitrogen compounds, offering a facile, green, and efficient alternative.

CircArid4b: A novel circular RNA regulating antibacterial response during hypoxic stress via apoptosis in yellow catfish (Pelteobagrus fulvidraco).

The intricate interaction among host, pathogen, and environment significantly influences aquatic health, yet the influence of hypoxic stress combined with bacterial infection on host response is understudied. Circular RNAs with stable closed-loop structures have emerged as important regulators in immunity, yet remain ill-defined in fish. In this study, we systematically explored the circRNA response in yellow catfish subjected to combined hypoxia-bacterial infection (HB) stress.

W/Mo/Cr Doping Modulates the Negative-Positive Inversion Gas Sensing Behavior of VO(M1).

The anomalous gas sensing behavior has garnered significant attention from researchers, prompting a re-evaluation of the gas sensing theory. This work focuses on inversion gas sensing behavior induced by element doping. W/Mo/Cr-doped VO(M1) samples are synthesized, and their sensing behaviors are investigated.

Solvent induced self-assembly of a dinuclear Eu(III) helicate and emergent strong CPL.

Herein, we report the influence of solvent on the self-assembly of a dinuclear helicate, (NMe)[Eu(LR)]. A multiple species mixture with the chemical composition of [Eu(LR)] present in CHCN can be transformed into a helicate upon increasing the content of CHCl, accompanied by a significant enhancement in circularly polarized luminescence activity.

Well-Defined PtCo@Pt Core-Shell Nanodendrite Electrocatalyst for Highly Durable Oxygen Reduction Reaction.

The rational design of efficient electrocatalysts with controllable structure and composition is crucial for enhancing the lifetime and cost-effectiveness of oxygen reduction reaction (ORR). PtCo nanocrystals have gained attention due to their exceptional activity, yet suffer from stability issues in acidic media. Herein, an active and highly stable electrocatalyst is developed, namely 3D PtCo@Pt core-shell nanodendrites (NDs), which are formed through the self-assembly of small Pt nanoparticles (≈6 nm).
