Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Smooth boundary topology optimisation applied to an electrostatic actuator

, 2008
Smooth boundary topology optimisation in conjunction with the continuum design sensitivity analysis avoids many of the problems encountered by conventional cell-based systems coupled with material homogenisation or the density method.

Excitation of VLF quasi-electrostatic oscillations in the ionospheric plasma

Annales Geophysicae
A numerical solution of the dispersion equation for electromagnetic waves in a hot magnetized collisionless plasma has shown that, in a current-free ionospheric plasma, the distortion of the electron distribution function reproducing the downward flow of

Hydrogen bonding, spectroscopic (FT-IR and FT-Raman), UV−Vis, and Mulliken charge analysis of Guanosine-5′ -Diphosphate: insight from DFT and molecular docking

Bibechana
Hybrid functional B3LYP has been used for quantum chemical calculation of Guanosine-5′ -Diphosphate (GDP) from DFT approach. The intra-molecular hydrogen bonding in the title molecule was rendered from Quantum theory of atoms in molecule (QTAIM).

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Electron Beams Generated by the Electron Kelvin‐Helmholtz Instability at a Quasi‐Perpendicular Shock

Geophysical Research Letters
Electron beams are considered to be important free energy sources for the excitation of various plasma waves at quasi‐perpendicular shocks. In this article, we perform a two‐dimensional particle‐in‐cell simulation of a low‐plasma‐β quasi‐perpendicular ...
