Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Impacts of Device Geometry and Layout on Temperature Profile during Large‐Area Photonic Curing

Advanced Engineering Materials, EarlyView.
The study investigates how gate geometry affects peak curing temperature during photonic curing of solution‐processed indium zinc oxide thin‐film transistors. Using 3D simulations and experimental validation, it reveals that larger gate areas and smaller aspect ratios increase curing temperature and thus improve transistor performance. Findings provide
