Microstructure characterization of multilayered TiSiN/CrN thin films

, 2014
Monolayered TiSiN and multilayered TiSiN/CrN coatings were synthesized by a cathodic arc deposition process. The chromium and Ti/Si (80/20 at.%) alloy targets were adopted as the cathode materials, altering the ratio of cathode current (/([TiSi])/1([Cr]))

Multilayer Architecture of PVD/HVOF Coatings Enables Transition in Wear Mechanism and Enhanced Tribological Performance

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT TiN films deposited by physical vapor deposition (PVD) are widely used as protective films due to their high hardness and wear resistance. However, their application under high‐load conditions is limited by poor load‐bearing capacity and susceptibility to spalling on soft substrates.

Microstructure and thermoelectric properties of CrN and CrN/Cr2N thin films [PDF]

, 2018
CrN thin films with an N/Cr ratio of 95% were deposited by reactive magnetron sputtering onto (0001) sapphire substrates. X-ray diffraction and pole figure texture analysis show CrN (111) epitaxial growth in a twin domain fashion.

Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Disentangling Sources of Uncertainty in CLM5 Model Predictions: Water, Energy, and Carbon Fluxes at European Observation Sites

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Land surface models (LSMs) such as the Community Land Model version 5 (CLM5) are central to climate–carbon assessments but exhibit persistent biases relative to site‐level observations. It remains unclear to what extent model‐data mismatches arise from uncertainty in meteorological forcing, soil properties, or vegetation traits, and to what ...

Surface analysis of electrochemically stripped CrN coatings

, 2013
CrN multilayer coatings are possible replacements for hard chromium because of their good mechanical and chemical properties. This paper focuses on X-ray photoelectron spectroscopy (XPS) to study the mechanism of electrochemical stripping of multilayered

X-ray residual stress analysis on CrN/Cr/CrN multilayer PVD coatings deposited on different steel substrates

, 2006
Hard physical vapour deposition (PVD) coatings as CrN, TiN and NbN have been successfully exploited for wear and corrosion protection. One limit to their performances under service is caused by the presence of large residual stresses, which adversely ...

DHCR24 Alleviates DNA Damage in Senescent Vascular Endothelial Cells via ENKUR/Ca2+ Signaling

Aging Cell, Volume 25, Issue 9, September 2026.
In senescent vascular endothelial cells, DHCR24 deficiency triggers ENKUR‐dependent Ca2+ overload, which in turn induces endoplasmic reticulum stress and mitochondrial dysfunction, ultimately exacerbating oxidative stress and DNA damage. ABSTRACT DNA damage is considered one of the major contributors to aging.
