Tailored synthesis of NdMnFeO perovskite nanoparticles with oxygen-vacancy defects for lithium-ion battery anodes.

In this study, we synthesize nanostructured NdMnFeO perovskites using a facile method to produce materials for the high-working-efficiency anodes of Li-ion batteries. A series of characterization assessments (e.g.

Binding Mechanism and Surface-Enhanced Raman Scattering of the Antimicrobial Sulfathiazole on Gold Nanoparticles.

A combined study using the surface-enhanced Raman scattering (SERS) technique and quantum chemical calculations was carried out to elucidate the adsorption behavior of sulfathiazole, an antibiotic drug, on gold nanoparticles. The tetrahedral Au cluster was used as a simple model to mimic a nanostructured gold surface. Computations using density functional theory with the PBE functional were performed in both the gas phase and aqueous medium using a continuum model.

In situ magnesiothermic reduction synthesis of a Ge@C composite for high-performance lithium-ion batterie anodes.

Metallothermic, especially magnesiothermic, solid-state reactions have been widely applied to synthesize various materials. However, further investigations regarding the use of this method for composite syntheses are needed because of the high reactivity of magnesium. Herein, we report an in situ magnesiothermic reduction to synthesize a composite of Ge@C as an anode material for lithium-ion batteries.

Development of Vang Danh anthracite as a cost-effective anode for sodium-ion batteries through a heat-treatment process.

This study focuses on the effects of the chemical process and heating time at 900 °C on pristine anthracite coal (provided by Vang Danh coal, Quang Ninh province, Vietnam) and explores its structure and electrochemical performance when used as an anode in Na-ion batteries. After chemical treatment with NaOH and HSO, the impurity content in the raw material decreased significantly (, ash content dropped from 4.4% to 0.

Emerging 2D/0D g-CN/SnO S-scheme photocatalyst: New generation architectural structure of heterojunctions toward visible-light-driven NO degradation.

Enhancing and investigating the photocatalytic activity over composites for new models remains a challenge. Here, an emerging S-scheme photocatalyst composed of 2D/0D g-CN nanosheets-assisted SnO nanoparticles (g-CN/SnO) is successfully synthesized and used for degrading nitrogen oxide (NO), which causes negative impacts on the environment. A wide range of characterization techniques confirms the successful synthesis of SnO nanoparticles, g-CN nanosheets, and 2D/0D g-CN/SnO S-scheme photocatalysts via hydrothermal and annealing processes.
