Thermal contact resistance for stationary and moving heat sources in angular contact ball bearings
Tribology and Materials, 2023 Sliding friction is a common tribological effect that occurs between the contact surfaces of the inner components (inner race, outer race and balls) of a spindle rolling bearing during operation.

A contact analysis for unconventional mounting processes of angular ball bearings
International Journal of Mechanics and Materials in Design, 2023 AbstractRigorous protocols must be followed when mounting ball bearings to avoid structural damage and subsequent malfunctioning or unexpected failures. Unconventional mounting procedures may produce excessive contact pressures between the elements of the bearing, therefore the whole process must be well-understood and modelled to prevent unwanted ...

Advanced 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,

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement
Advanced Materials Interfaces, EarlyView.Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.
