Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives
ChemPhotoChem, EarlyView.The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.

ChemPhotoChem, EarlyView.Photoprotection is a current and relevant topic; therefore, the development of new sunscreens is necessary. To this end, nature is examined for molecules such as mycosporine‐like amino acids and gadusol. Through rational design, this study has successfully synthesized new UV filters and evaluated their photoprotective and antioxidant properties ...

Exploring Acrylic Acid as an Oxirane Nucleophile: Direct Access to Poly(β‐Hydroxy Acrylates)
ChemSusChem, EarlyView.Within, we present a scalable, solvent‐free route to β‐hydroxy acrylate monomers using acrylic acid (AA) as a nucleophile with various oxiranes. Once polymerized, the resulting polymers are optically transparent, thermally stable, and range from brittle to ductile. This straightforward method underscores AA's potential in sustainable, bio‐based polymer

European Journal of Lipid Science and Technology, EarlyView.Nanoemulsions were obtained by ultrasonication using lemon oil, and the effects of lemon oil nanoemulsions at a nanoscale on certain quality characteristics of both raw and thermally treated fish meat were investigated. It is recommended that thermal treatment be applied prior to the incorporation of lemon oil nanoemulsion, ensuring optimal results in ...
