Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment
Materials and Corrosion, EarlyView.Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Stability of High-Level Radioactive Waste Forms [PDF]
, 2001 High-level waste (HLW) glass compositions, processing schemes, limits on waste content, and corrosion/dissolution release models are dependent on an accurate knowledge of melting temperatures and thermochemical values. Unfortunately, existing models for predicting these temperatures are empirically-based, depending on extrapolations of experimental ...

Modified Fisher distribution model for fracture orientations with antipodal symmetry
Shuiwen dizhi gongcheng dizhiThe statistical characteristics of structural plane orientations in fractured rock mass are usually described by Fisher distribution model, which maps the normal direction determined by dip angle and dip direction to random points on a unit sphere.

Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles
Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.
