Respirable Dust Exposure in Western Australian Mining: Trends, Variability, and Implications for Occupational Health

American Journal of Industrial Medicine, Volume 69, Issue 7, Page 540-547, July 2026.
ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.

An Integrated Chemicals‐Free Circular Model for Lithium Recovery From Spent Batteries to Direct Lithium Extraction From Brines

Battery Energy, Volume 5, Issue 3, May 2026.
A simple, chemical‐free method based on a 5‐min microwave treatment and using only water enables the synthesis of Li/Al layered double hydroxides (LDHs) from waste lithium‐ion batteries. These Li/Al LDHs can then be used for lithium extraction from primary resources, supporting a truly sustainable circular economy for lithium.
