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,

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

Small, Volume 22, Issue 26, 8 May 2026.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Local Structure and Vacancy Distribution in Transition Metal Carbides: Results From High‐Resolution 13C NMR Spectroscopy

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...
