Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Artisanal and Small-Scale Gold Mining

, 2021
Artisanal gold mining occurs informally and therefore relies on low technologies and extraction methods lacking pollution controls. As a result, despite the fact that artisanal gold mining produces only twenty percent of the world’s gold, it releases more mercury than any other sector and represents the largest source of mercury emissions.
