Summary: Molybdenum oxide is a material with high bandgap, work function, and other interesting properties. Using Pulsed Laser Deposition, researchers were able to deposit high transparency MoO3 layers from stoichiometric MoO3 and metal Mo targets at different temperatures and oxygen pressures. Optical properties were accurately tracked using Photothermal Deflection Spectroscopy and Spectral Ellipsometry, while crystallinity and surface morphology were monitored using X-ray diffraction and Scanning Electron Microscopy. Increasing temperature led to smoother, denser layers, narrowing bandgap, and increased sub-gap absorption, with crystallization occurring above 400 degrees C. Sub-gap absorption around 1000 nm depended on temperature and weakly on oxygen pressure.

Summary: Samarium doped ceria thin films were successfully deposited on Si (100) substrates at 500 and 600 degrees C using Pulsed Laser Deposition. X-ray Diffraction confirmed the presence of Samarium Doped Cerium Oxide crystalline compound in the films. Atomic Force Microscopy and Scanning Electron Microscopy revealed high quality films with low roughness, especially for the sample deposited at 600 degrees C. X-ray Photoelectron Spectroscopy showed an increased proportion of Ce3+ in the deposited films compared to the target. Spectroscopic Ellipsometry analysis calculated a refractive index under 2.2 in the visible and near-infrared domain. Nanoindentation tribometric measurements indicated a decrease in elasticity modulus and hardness with increasing substrate temperature. These films show potential as electrolyte materials for new generation electrochemical devices.

Summary: The paper investigates the fretting and wear behavior of pure copper and pure titanium coatings achieved through cold spray, finding that materials with low porosity and high strength exhibit high resistance to wear damaging. The hardness of the coatings varies based on distance from the substrate and thickness, influencing the response to wear damaging. Coatings with greater thickness demonstrate better wear resistance due to deformation hardening, but also exhibit brittle fracture at higher loads.
