Controlling Selectivity at the First Hydrogenation Level: Synthesis of 3-Hydroxyisoindolines by Heterogeneously Silver-Catalyzed Monohydrogenation of Phthalimides. [PDF]
Adv Sci (Weinh)3‐Hydroxylactams are obtained from phthalimides through a heterogeneous catalyzed chemoselective hydrogenation, able to stop the process at the first hydrogenation level. By using a rationally designed [Ag/Al2O3] recyclable solid nanocatalyst, a wide range of cyclic hemiamidals are accesed through a full atom‐economical reaction that preserves (hetero ...

Development of Efficient Supramolecular Photostabilizer for Carotenoids and Retinoids: Analyses and Application Research. [PDF]
J Cosmet DermatolABSTRACT Background Carotenoids and retinol are well known for their potent antioxidant and biological properties in pharmaceuticals, foods, and cosmetics. However, their poor photostability presents a significant challenge that cannot be effectively addressed through simple formulation strategies such as encapsulation.

Liposomal Delivery of Cell Impermeable Phototoxic Ru(II) Complexes. [PDF]
ChembiochemPeptidoliposomes surface decorated with cell‐penetrating octaarginine peptide carry cell‐impermeable photocytoxic 1,10‐phenanthroline‐5,6‐dione derivatives of Ru(II) into live cells. Uptake mechanism and localization were found to be cell‐line dependent.

Plasma-Tunable Metasurfaces for SERS Nanosensing of Hazardous Chemicals. [PDF]
SmallOne‐step oxygen plasma sculpting of copper into vertically aligned oxide nanosheets is reported via energetic ion bombardment and defect‐mediated growth. Magnetron‐sputtered silver nanoparticles decorate these sheets to yield a plasmonic metasurface whose network of hot spots amplifies multi‐wavelength SERS signals for explosive and related hazardous ...
