Ion Beam Sputtering Deposition to Prepare Pt/ZrO2 Active Layer for Hydrogen Evolution and Oxidation Reaction

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Pt@ZrO2 thin films are fabricated by ion beam sputtering as compact, binder‐free electrodes with low Pt loading (0.0475 mg·cm−2). The intimate mixing between the noble metal and the ceramic support enhances intrinsic catalytic activity toward alkaline hydrogen evolution, allowing a significant reduction in precious metal loading while maintaining ...

Tool Life of PM-HSS Cutting Tools when Milling of Titanium Alloy [PDF]

, 2017
Machining of titanium alloys meets with poor life of a cutting tool. It is caused by a low thermal conductivity and by a high strength-to-weight ratio of the alloys. Various approaches for cost-effective and productive machining titanium alloys are still

Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

Investigation of Structural, Mechanical and Electrochemical Properties of Temperature‐Dependent Dual AlN/TiAlN Coating Synthesized by CVD Process

Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,
