Interface Engineering in Solid‐State Sodium Batteries: Advances in Materials Design, Interfacial Strategies, and Multiscale Characterization

Interdisciplinary Materials, EarlyView.
Since solid‐state sodium batteries (SSSBs) are a promising solution for advancing sodium‐based energy storage, it is necessary to systematically summarize the development process of SSSBs. It focuses on the role of interface engineering in addressing challenges such as materials design, interfacial strategies, and multiscale characterization.

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

Particle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Regulating TGO Nucleation and Growth of MCrAlX Coatings via Femtosecond Laser Remelting: The Role of Reactive Elements in the Oxidation Resistance

Rare Metals, EarlyView.
ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser
