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 ...

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting T g,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior T g of 135°C ...

(+)‐Trans‐Cannabidiol Is an Agonist at Human CB2 Receptors

Pharmacology Research &Perspectives, Volume 14, Issue 5, October 2026.
ABSTRACT (−)‐trans‐Cannabidiol ((−)‐CBD) is a principal phytocannabinoid from Cannabis sativa. (−)‐CBD has complex pharmacology but is a relatively weak inhibitor of CB1 and CB2 receptor signaling. Cannabidiol has two chiral centres and thus four stereoisomers.

Supramolecular Behaviour of Heterochiral Dipeptides With Ile

Journal of Peptide Science, Volume 32, Issue 10, October 2026.
This study describes the supramolecular behaviour and gelation of heterochiral, aliphatic dipeptides d‐Ile‐l‐Xaa (Xaa = Ala, Val, Leu or Ile) in various solvents and buffered water at neutral pH. Metastable gels rapidly crystallised. X‐ray diffraction analysis was conducted to unveil the dipeptides' packing modes in amphipathic layers.
