Silicon (Si) is considered the most promising anode material for next-generation high-energy lithium-ion batteries. To enable use of pure Si anodes, patterning essential to reduce electrode degradation caused by volume changes during cycling. The authors herein report a facile and scalable Cu electrodeposition (Cu-ECD) process tailor topography current collectors directed formation columnar ano...

A scalable strategy for three-dimensional (3D) assembly of dissimilar materials with nanometer resolution is key to harness the full potential of physical properties expected within the quantum-confined or interface-dominated size regime. Chemical synthesis methods yield layered and coaxial nanowires and branched nanocrystals, while physical vapor deposition (PVD) techniques are particularly ef...

This article introduces a continuous, gas-phase method for depositing thin metallic coatings onto (nano)particles using a type of physical vapor deposition (PVD) at ambient pressure and temperature. An aerosol of core particles is mixed with a metal vapor cloud formed by spark ablation by passing the aerosol through the spark zone using a hollow electrode configuration. The mixing process rapid...

Plasma spray-physical vapor deposition (PS-PVD) is an emerging technology for the of uniform and large area coatings. As characteristics plasma jet are difficult to measure in whole chamber, computational fluid dynamics (CFD) simulations could predict temperature, velocity pressure fields. However, as PS-PVD generally operated at pressures below 500 Pa, a question rises about validity CFD predi...

The results of research aimed at the gas sensing nanowires (NWs) engineering are presented. Structurally modulated SnO2 NWs were obtained at 900С in the modified vapor-solid process, allowing that NW morphology could be encoded in a programmable way along its length. PVD technique was used for Ti/Au electrical contacts deposition and gas sensitive nanoscale chemiresistors formation. Created nan...

Recent research has shown that KCl:Eu²⁺ has great potential for use in megavoltage radiation therapy dosimetry because this material exhibits excellent storage performance and is reusable due to strong radiation hardness. This work reports the authors' attempts to fabricate 2D KCl:Eu²⁺ storage phosphor films (SPFs) using both a physical vapor deposition (PVD) method and a tape casting method. X...

SAM formation of undecanethiol (UDT) and mercaptoundecanoic acid (11-MUA) on Au(111) and on gold foils, using wet chemical preparation methods as well as physical vapor deposition (PVD) in UHV, has been studied by means of thermal desorption spectroscopy (TDS), low energy electron diffraction (LEED), and Auger electron spectroscopy (AES). The main aim of this study was to explore the possible a...
