The adsorption/absorption of hydrogen at room temperature by palladium, 16% silver-palladium and 5% ruthenium-palladium foils was studied using thermal desorption spectroscopy. Hydrogen readily diffused in the palladium and desorbed as one broad peak at about 650 K. Hydrogen also diffuses in the 16% silver-palladium foil and in the 5% rutheniumpalladium foil but with a smaller diffusion constan...

A brief status report on bearing technology and present and near-term future problems that warrant research support is presented. For rolling element bearings a material with improved fracture toughness, life data in the low A region, a comprehensive failure theory verified by life data and incorporated into dynamic analyses, and an improved corrosion resistant alloy are perceived as important ...

We are reporting the results of studies on issues related to the injection stripping foil in the Spallation Neutron Source (SNS) accumulator ring. The problems related to foil heating and foil lifetime, such as current density distribution and temperature distribution in the foil, are investigated. The impact of injection errors on the beam losses at the foil is studied. The particle traversal ...

Among efforts to improve techniques for the chemical vapor deposition of large-area and high-quality graphene films on transition metal substrates, being able reliably transfer these atomistic membranes onto desired substrate is a critical step various practical uses, such as graphene-based electronic photonic devices. However, most used approach, wet etching process based complete remains grea...

The analysis of construction curves limiting deformations metals is carried out in the work. It established that traditional test methods, such as deposition and stretching cylindrical specimens, do not ensure constancy stress state, therefore contribute to history deformation curves. During deposition, there an increase state due curvature lateral surface sample (barrel formation), which cause...
