New Transparent Rare‐Earth‐Based Hybrid Glasses: Synthesis, Luminescence, and X‐Ray Imaging Application

Aggregate, EarlyView.
A desolvation method below 140°C was reported for a rapid synthesis of RE(NO3)3(C5H2N4)2 hybrid glasses within an hour. The glasses containing the whole library of rare‐earth ions exhibited a high transparency, which provided an ideal matrix for the energy‐transfer investigation between organic linker and rare‐earth ions.

Sequence Control in Sulfur‐Containing Ring‐Opening Co‐ and Terpolymerisations

Angewandte Chemie International Edition, Accepted Article.
Sulfur‐containing polymers uniquely expand the catalogue of accessible material properties compared to current commodity materials, yet their synthesis remains underdeveloped. Combining sulfur‐ and oxygen‐containing monomers in ring‐opening copolymerisation leads to a reshuffling reaction of the sulfur centres, which has been challenging to control — a

Preparation, Characterization, and Antimicrobial Activities of Ceragenins Incorporated Into Polyvinyl Alcohol/Gelatin/Sodium Alginate‐Based Hydrogels for Treatment of Burn Wounds

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Ceragenins are synthetic molecules that mimic antimicrobial peptides (AMPs) in the human immune system. They feature a bile acid‐based structure with appended positively charged groups that disrupt bacterial cell membranes, leading to microbial cell death or inactivation.
