The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Sulfur Vacancy Engineering of Coralloidal Bi2S3@In2S3 Heterojunction for Enhanced Photocatalytic Removal of Cr(VI)/Antibiotic Mixed Pollutants

open access: yesRare Metals, EarlyView.
ABSTRACT Defects can tune the band structure of semiconductors, thereby reconfiguring the corresponding heterojunctions. In this study, coralloidal Bi2S3@In2S3 heterostructures rich in sulfur vacancies were successfully developed via a one‐step hydrothermal method with content regulation of the sulfur source.
