Parabens in male infertility—Is there a mitochondrial connection? [PDF]
Parabens are widely used as preservatives in many foods, cosmetics, toiletries, and pharmaceuticals due to their relatively low toxicity profile and to a long history of safe use. Parabens are alkyl esters of p-hydroxybenzoic acid and typically include methylparaben, ethylparaben, propylparaben, butylparaben, isobutylparaben, isopropylparaben and ...

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...
