Ultrasound field distribution and ultrasonic oxidation desulfurization efficiency

Ultrasonics Sonochemistry, 2013
Ultrasonic oxidation desulfurization (UODS) has been considered a promising method for deeply desulfurization technology since it can be carried out using mild conditions. During the last few decades many experimental investigations have been carried out on optimizing the reaction condition such as ultrasonic irradiation time, oxidizing reagents amount,

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

Advanced Science, Volume 13, Issue 22, 17 April 2026.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...

Sustainable KCl‐Assisted PbI2 Recycling for High‐Performance Quantum Dot Solar Cells

Advanced Science, Volume 13, Issue 19, 2 April 2026.
An additive‐assisted lead recycling strategy is developed by introducing trace KCl during PbI2 recrystallization from spent lead‐acid batteries. KCl regulates crystallization and impurity removal, yielding high‐purity PbI2 and enabling the formation of colloidally stable PbS and CsPbI3 quantum dots.
