Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, Volume 14, Issue 8, August 2025.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

International Journal of Cosmetic Science, Volume 47, Issue 4, Page 604-625, August 2025.The protein carbonylation biomarker is validated as reliable molecular damage marker to monitor hair oxidative damage (chemical and photo oxidation). It is slightly more sensitive than the cysteic acid in the case of photochemical oxidation and allows to geolocate qualitatively and quantitatively the oxidation within the hair fibre substructures ...

Biotropica, Volume 57, Issue 3, May 2025.Shade houses serve as effective scientific tools for ex situ cultivation and orchid conservation in tropical forests. A comparison of the floral scent chemistry of Cyrtorchis letouzeyi between shade houses and natural populations in Cameroon revealed the same dominant compound, identical qualitative compositions across sites, but variations in emission
