Article Abstract

A simple one-pot synthesis of Ni nanoparticle/ordered mesoporous carbon composite electrode materials is demonstrated for electrosynthesis for the first time. The obtained nanocomposites have uniform mesopore sizes (3.0-3.7 nm), large specific surface areas (506-633 m g), high pore volumes (0.28-0.38 cm g), well-graphitized carbon frameworks, and uniformly dispersed Ni nanoparticles (7-15 nm) embedded in the carbon pore walls. The prepared materials show very high performance in the selective (∼84%) electrocatalytic reduction of aromatic ketones into alcohols (∼79%).

Developing low-temperature gas sensors for parts per billion-level acetone detection in breath analysis remains challenging for non-invasive diabetes monitoring. We implement dual-defect engineering via one-pot synthesis of Al-doped WO nanorod arrays, establishing a W-O-Al catalytic mechanism. Al doping induces lattice strain to boost oxygen vacancy density by 31.

In this study, a one-pot hydrothermal synthesis method was used to synthesize a novel gold-yttrium trimesic acid metal-organic framework (Au-Y-TMA MOF), demonstrating significant improvements over conventional single-metal MOFs, that is, yttrium trimesic acid (Y-TMA), in both supercapacitor applications and electrochemical antibiotic detection. The X-ray diffraction patterns of Au-Y-TMA confirmed the presence and impact of Au in the Y-TMA matrix, while field emission scanning electron microscopy (FE-SEM) images revealed a heterogeneous combination of gold nanoparticles (AuNPs) and Y-TMA, suggesting a nonuniform distribution and possible interaction. The developed half-cell supercapacitor exhibited a remarkable capacitance value of 1836 F/g at a current density of 5 A/g by galvanostatic charging-discharging (GCD) measurement.

A one-pot strategy was developed for the synthesis of α-substituted 2-benzofuranmethamines from salicylaldehydes, phenylacetylenes, and cyclic secondary amines using CuFeO as a bifunctional catalyst. The reaction proceeds at 80 °C in 1,4-dioxane using CsCO as a base, enabling sequential A-coupling, 5--dig cyclization, and 1,3-allylic rearrangement in a single operation. Unlike previous methods, this protocol employs non-precious metal catalysts and mild reagents, operates under moderate conditions, and provides direct access to α-substituted 2-benzofuranmethamines in good yields (80-96%) with broad substrate compatibility.

Strangles, a highly contagious disease caused by subspecies (), significantly impacts horse populations worldwide, with Iceland as the only exception. This disease poses serious threats to equine health and results in considerable economic losses. Consequently, the accurate, sensitive, and rapid detection of from clinical samples is essential for early warning and effective disease management.
