Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Journal of Forensic Sciences, EarlyView.Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Contact Dermatitis, EarlyView.Nail charms are increasingly popular additions to traditional nail treatments. Nickel release was detected in 38.5% of nail charm products by DMG spot test and 67.5% of products by XRF. Nail charms may represent an underrecognized source of consumer exposure in the United States.
