Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Dual‐Emission Carbon Dot Nanozymes Mitigate Salt Stress and Enhance Photosynthesis for Crop Germination and Growth

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Dual‐emission carbon dot nanozymes are synthesized via microwave method. The nanozymes enhance photosynthesis corn seedlings through spectral‐matched light conversion. Their superoxide dismutase‐mimetic activity scavenges salt stress‐induced reactive oxygen species and circumvents energy‐intensive stress responses.

Synthesis of Functional Materials Using N‐heterocyclic Amines Beyond Melamine

Advanced Science, Volume 12, Issue 40, October 27, 2025.
Melamine has long enabled supramolecular assemblies, polymers, and carbon nitrides, yet related N‐heterocyclic amines remain underexplored. This review highlights advances with melamine analogues such as 6‐phenyl‐, 6‐methyl‐triazine diamines and 2,4,6‐triaminopyrimidine, focusing on how structural variation governs reactivity, condensation, and ...

Progress on the development of Class A GPCR‐biased ligands

British Journal of Pharmacology, Volume 182, Issue 14, Page 3249-3300, July 2025.
Class A G protein‐coupled receptors (GPCRs) continue to garner interest for their essential roles in cell signalling and their importance as drug targets. Although numerous drugs in the clinic target these receptors, over 60% GPCRs remain unexploited. Moreover, the adverse effects triggered by the available unbiased GPCR modulators, limit their use and
