Sulfation‐Tunable Peptide‐Glycosaminoglycan Hydrogels for Hematopoietic Stem and Progenitor Cell Expansion

Advanced Functional Materials, EarlyView.
Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

A Naphthalimide‐Based NIR‐Emissive AIE Photosensitizer for Synergistic Apoptosis/Ferroptosis‐Mediated Antitumor Therapy and Broad‐Spectrum Bacterial Inactivation With Rapid Wound Healing

Advanced Healthcare Materials, EarlyView.
An ionic naphthalimide AIE photosensitizer (PS), TPAPV‐NIM‐M, anchors to cellular and bacterial membranes, emits in the far‐red/near‐infrared (NIR) region, and efficiently generates reactive oxygen species (ROS) under white light. Its membrane‐localized photodynamic action drives apoptosis/ferroptosis‐mediated tumor suppression and broad‐spectrum ...

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.
