Geochemical evaluation and driving factor analysis of soil salinization in Northeast China Plain

open access: yesFrontiers in Environmental Science
IntroductionThe Songnen Plain in Northeast China is considered as one of the world's three major saline-alkali land regions. However, the evaluation of the extent and degree of saline-alkali land has primarily been mainly obtained via remote sensing ...

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

open access: yesAdvanced 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

A Reusable Polymeric Sensor Based on Green‐Synthesized CQDs@ZIF‐8 for the Rapid Detection of Nitro‐Explosive Picric Acid

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents the rational design and synthesis of a highly luminescent polymeric nanocomposite. Initially, highly fluorescent carbon quantum dots (CQDs) are synthesized via a facile hydrothermal method using citric acid and β‐alanine as precursors, followed by rigorous purification through centrifugation and filtration.
