Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Investigation of the Optical and Morphological Properties of PS/POMA Blends Hybridized With Erbium Oxide (Er2O3)

Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
ABSTRACT Polymeric blends (PB) represent a rapid and cost‐effective strategy for the development of materials with tailored properties. In this study, blends of polystyrene (PS) and poly(o‐methoxyaniline) (POMA) containing 7.5 wt/wt% of POMA were prepared and hybridized with erbium oxide (Er2O3) at concentrations of 0.5, 1.0, and 3.0 wt/wt%.

Fragmentation Pathways of Diaminomaleonitrile: Automated Discovery and High‐Level Energetics Under Laser‐Driven Conditions

ChemPhysChem, Volume 27, Issue 6, 27 March 2026.
Laser irradiation of a 2,3‐diaminomaleonitrile (DAMN) molecule (white) induces decomposition into the highlighted products (yellow). The laptop denotes a computational simulation designed to mimic the laser ablation experiment. We investigate the fragmentation chemistry of 2,3‐diaminomaleonitrile (DAMN), a key hydrogen cyanide (HCN) tetramer in ...
