Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

Advanced Materials Interfaces, EarlyView.
ABSTRACT 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

Wire Electrical Discharge Machining of Micro-Involute Gears.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994
Micro-involute spur gears with a module of less than 0.1 are fabricated by wire electrical discharge machining instead of conventional rack cutting since rack cutters with a fine module are very difficult to fabricate. This paper shows that undercutting of involute tooth profile occurs when the module of the microgear is small because the width of ...

Roll‐to‐Roll Manufacturing of Flexible Thermoelectric Semiconductors Using Low‐Level Direct‐Current Sputtering

Advanced Materials Technologies, EarlyView.
Roll‐to‐roll direct‐current sputtering enables room‐temperature manufacture of flexible bismuth telluride thermoelectric films. By identifying a low‐power deposition window that suppresses charge‐induced arcing, this work links sputtering conditions to film structure, charge transport, and thermoelectric performance, achieving a room‐temperature figure
