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

open access: yesAdvanced Materials Interfaces, EarlyView.
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,

Vegetation databases augment but do not replace species distribution atlases in species richness assessment

open access: yesEcological Indicators, 2023
Mapping of species richness (SR) patterns is pivotal for biogeography and nature conservation. Vegetation plot databases serve as a new source of information, but they are inherently affected by the methodological background of data collection.
