Investigating CMAS corrosion in ultrahigh temperature Hf6Ta2O17‐based thermal barrier coatings: A mechanism by which corrosion products hinder corrosion resistance

open access: yesMaterials Genome Engineering Advances, EarlyView.
During the corrosion of Hf6Ta2O17 by CMAS, stable corrosion products—CaTa2O6 and HfSiO4 form at the interface, which hinder further corrosion of Hf6Ta2O17 by CMAS. This mechanism successfully explains the excellent CMAS corrosion resistance of the Hf6Ta2O17 thermal barrier coating.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

From Pigeons to Raptors: Avifauna Across the Early Upper Paleolithic Sequence of Manot Cave, Israel

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Avian exploitation during the Early Upper Paleolithic (EUP) is frequently interpreted as a marker of socioeconomic intensification across Europe and the Levant. However, the specific character of avian exploitation in the Levant has remained unexplored due to the scarcity of detailed zooarchaeological analyses. This study addresses this gap by

Impact of Electrolyte Temperature on Solution‐Combustion Synthesized NiO/Ni Nanoparticles as Oxygen Evolution Reaction Electrocatalyst

open access: yesChemistryOpen, EarlyView.
Electrolyte temperature significantly affects electrocatalyst performance in water splitting reactions. Catalysts synthesized by solution combustion synthesis were evaluated for oxygen evolution activity at different temperatures. Elevated temperatures reduced overpotential and increased current density, reflecting enhanced reaction kinetics and ...
