Integrating Vibrio natriegens for Photon Manipulation in Living Lighting Devices

open access: yesAdvanced Materials, EarlyView.
Rationalization of genetic and material engineering tools has enabled the engineering of fluorescent Vibrio natriegens (V. natriegens) to fabricate straightforward, highly emissive and stable V. natriegens‐silicones color filters for the first red‐emitting bacteria‐hybrid light‐emitting diodes. This pinpoints V. natriegens as a high‐performance protein

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

open access: yesAdvanced 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.

Engineering Free Volume within Frontal Ring‐Opening Metathesis Polymerization via Pendant Plasticization

open access: yesAdvanced Materials, EarlyView.
Norbornene‐based copolymers with tunable n‐alkyl pendant length provide control over matrix free volume, enabling elastomeric materials via frontal ring‐opening metathesis polymerization (FROMP). ABSTRACT Frontal ring‐opening metathesis polymerization (FROMP) enables rapid, energy‐efficient access to high‐performance thermosets and thermoplastics, but ...

Microenvironment Modulation‐Based Nanomaterial‐Loaded Hydrogel Dressings for Diabetic Foot Ulcers: Research Progress and Future Perspectives

open access: yesAdvanced Materials Interfaces, EarlyView.
xx xx. ABSTRACT Diabetic foot ulcer (DFU) is a chronic complication of diabetes, primarily caused by hyperglycemia, peripheral vascular disease, and neuropathy. Characterized by persistent hyperglycemia, impaired perfusion, inflammation, and infection, DFUs pose significant challenges to healing and are associated with high morbidity and amputation ...
