Adhesion, friction and Auger spectroscopy analysis of a commercial cobalt base aircraft turbine shroud alloy [PDF]
A commercially used cast cobalt base alloy was investigated as a turbine shroud material which revealed a surface enriched with tungsten and carbon suggesting a surface layer of tungsten carbide. Adhesion and friction of this segregated surface layer are

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry
Advanced Materials, EarlyView.Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

Microstructural Evolution Dynamics in Rapid Joule Heating Densification of High‐Nickel Cathodes
Advanced Materials, EarlyView.Introduction of high‐temperature rapid Joule heating combined with two‐step sintering drives full densification while suppressing grain coarsening in high‐Ni cathodes. By activating lattice and grain boundary diffusion over surface diffusion, this approach achieves dense microstructures without excessive grain growth, offering insights into the ...

Advanced Materials Interfaces, EarlyView.Silicon clathrates are a promising class of materials with a unique, cage‐like structure that differs from the conventional cubic diamond crystalline silicon (c‐Si) structure. Type I silicon clathrates are metallic, while type II clathrates are semiconductors with a wide bandgap, which can exceed 1.9 eV.
