Published: October 2020

The effect of fluoride coatings, an effective approach to suppress HF corrosion, on the cycling stability of NCM523 cathodes is systematically studied. It is the first study to reveal that fluoride coatings significantly restrain interfacial reactions when, simultaneously, the fluoride suspension possesses an appropriate pH (near 4.0) and there is a small cation ionic radius.

Although fluorescence analysis methods are widely used in pesticide residue detection, improving their sensitivity and selectivity remains a challenge. This paper presents a novel ratio fluorescence sensor based on the molecular imprinting polymers (MIPs) and metal-enhanced fluorescence for visual detection of dicamba (DIC). Calcium fluoride (CaF) quantum dots (QDs) were immobilized on the surface of Ag@MIPs, resulting in a blue fluorescence response signal (Ag@MIPs-CaF).

Atomic layer deposition (ALD) is a popular method of coating battery electrodes with metal oxides for improved cycling stability. While significant research has focused on the interaction between the reactive metal alkyl precursor and the electrode materials, little is known about the reactivity of the precursor toward other components of the battery electrode, such as the polymer binder. This study presents a combined computational and experimental investigation of the reaction between the popular polyvinylidene (PVDF) binder and the trimethylaluminum (TMA) precursor commonly used for coating AlO by ALD.

The use of supercritical carbon dioxide (ScCO) as a replacement for volatile organic solvents in coatings has the potential to reduce air pollution. This paper presents the findings of a molecular dynamics simulation study investigating the dissolution behavior of polyvinylidene fluoride (PVDF) in ScCO assisted by five co-solvents. On the basis of solubility parameters, interaction binding energy, and radial distribution functions, the impacts of temperature, pressure, and co-solvents on the compatibility of ScCO and PVDF were investigated at the microscopic level.

Bacterial infections are a common cause of clinical complications associated with the use of orthodontic microimplants. Biofilm formation on their surfaces and subsequent infection of peri-implant tissues can result in either exfoliation or surgical removal of these medical devices. In order to improve the properties of microimplants, hybrid coatings enriched with silver nanoparticles, calcium, and phosphorus were investigated.

Functionalized Polyethylene Separators with Efficient Li-Ion Transport Rate for Fast-Charging Li-Ion Batteries.

ACS Appl Mater Interfaces

January 2025

School of Materials Science and Engineering, Xihua University, Chengdu, Sichuan 610039, China.

Fast-charging lithium-ion batteries (LIBs) are the key to solving the range anxiety of electric vehicles. However, the lack of separators with high Li transportation rates has become a major bottleneck, restricting their development. In this work, the electrochemical performance of traditional polyethylene separators was enhanced by coating AlO nanoparticles with a novel green binder.
