Advances in organic UV filters for sunscreens over the past decade
Photochemistry and Photobiology, EarlyView.Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2013 In this study, several derivatives of amines were diazotized and coupled with 3-aminocrotonitrile to give 2-arylhydrazon-3-ketiminocrotononitrile. The synthesized components were then refluxed with hydrazine hydrate in ethanol to give a series of dyes 5 ...

Experimental and Computational Elucidation of Protic Redox Reaction Mechanisms
ChemElectroChem, Volume 13, Issue 13, 2 July 2026.Comparing quantum chemical calculations of redox potentials against experimental data provides a powerful and cost‐effective method for validating proposed protic redox reaction mechanisms, provided that computational and experimental uncertainties are robustly quantified. Molecular design of redox‐active species for applications such as redox sensing,

The Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3593-3617, July 2026.Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

ChemistryOpen, Volume 15, Issue 7, July 2026.Epoxy Clerodane Diterpene (ECD) significantly reduces adipocyte hypertrophy and lipid accumulation in human mesenchymal stem cell (hMSC)‐derived adipocytes. ECD improves mitochondrial membrane potential (ΔΨm), increases thermogenic regulators (UCP‐1, PPARγC1α), decreases adipogenic markers (C/EBPα, PPARγ), and reduces inflammatory mediators (TNF‐α, NF ...
