The electrochemical oxidation of 5-hydroxymethylfurfural (HMF), derived from biomass, offers a sustainable route to valuable chemicals like 2,5-furandicarboxylic acid, used for the production chemicals, polymers, and biofuels. Cobalt-based catalysts, especially Co3O4, have shown promise HMF electrooxidation, but their poor conductivity limits applicability. To address this issue, we synthesized compared catalytic activity Au–Co branched core–shell nanoparticles. We demonstrate that...
Creating high surface area nanocatalysts that contain stacking faults is a promising strategy to improve catalytic activity. Stacking can tune the reactivity of active sites, leading improved performance. The formation branched metal nanoparticles with control fault density synthetically challenging. In this work, we demonstrate varying branch width by altering size seed grows off an effective method precisely in Ni nanoparticles. A across branches was found lower energy barrier for...
3D interconnected structures can be made with molecular precision or micrometer size. However, there is no strategy to synthesize dimensions on the scale of tens nanometers, where many unique properties exist. Here, we bridge this gap by building up nanosized gold cores and nickel branches that are directly connected create hierarchical nanostructures. The key approach combining cubic crystal-structured hexagonal in multiple steps. morphology controlled tuning at each synthetic step. These...
The presence of defects can significantly improve catalytic activity and stability, as they influence the binding reactants, intermediates, products to catalyst. Controlling in structures nanocrystal catalysts is synthetically challenging.

Nano zero-valent metals (nZVMs) have been extensively utilized for decades in the reductive remediation of groundwater contaminated with chlorinated organic compounds, owing to their robust reducing capabilities, simple application, and cost-effectiveness. Nevertheless, there remains a dearth information regarding efficient defluorination linear or branched per- polyfluoroalkyl substances (PFASs) using nZVMs as reductants, largely due absence appropriate catalysts. In this work, various...
We develop highly robust and stretchable conductive transparent electrodes based on silver nanowires (AgNWs) deposited functionalized chitosan biopolymer substrates. 11-aminounde-canoic acid is introduced as a surface modifier for enhancing the chemical bond. The chemically AgNW films achieve low sheet resistance of 12.2 ohm/sq with high transmittance 88.9%. In addition, alternating current-driven electroluminescent devices heaters have been fabricated AgNW/chitosan thin-films which can be...
The abundance of applications alginates in aqueous surroundings created by their interactions with water is a fascinating area research. In this paper, computational analysis was used to evaluate the conformation, hydrogen bond network, and stabilities for putative intermolecular between alginate dimers molecules. Two structural forms (alginic acid, alg, sodium alginate, SA) were evaluated density functional theory (DFT-D3) method at B3LYP basis set 6-31++G** chosen calculating data....

The development of Pt on Ni nanoparticles is critical for the improvement water splitting reactions. Here, growth small, below 2 nm islands crystalline branched was investigated by tuning size using a slow seeded-growth synthesis. Smaller island results in greater shift hydrogen binding energy sites, as characterized underpotential peak position voltammogram. This indicates weakening to hydrogen, which leads enhanced alkaline evolution reaction activity with smaller size.
