Dynamic Disulfide Ionogels for Self‐Healing, Transparent, and Elastic E‐Skins

open access: yesAdvanced Materials Technologies, EarlyView.
A dynamic covalent ionogel is designed via polymer–ionic liquid interaction control. The interplay between ionic liquid compatibility, viscosity, and concentration governs polymer segmental dynamics, which in turn regulates disulfide exchange kinetics and mechanical durability.

A New Series of Bis (Thiosemicarbazone) Derivatives: Synthesis, Spectroscopic Characterization, and Antioxidant Activities

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
New bis (thiosemicarbazone) derivatives (1-5) were obtained from thiophene-2,5-dicarbaldehyde and numerous thiosemicarbazides. The thiosemicarbazides were prepared various isothiocyanates and hydrazine monohydrate.

Should I Stay or Should I Go—Leveraging an Overlooked Feature of Click‐to‐Release Chemistry for Affinity Labeling

open access: yesAngewandte Chemie, EarlyView.
Click‐to‐release (C2R) chemistry is redirected from payload liberation toward ligand‐directed covalent protein labeling through a transient dihydropyridazine methide (DHP‐methide). This concept opens the way to dual‐functional systems combining covalent target engagement with controlled effector release.

Sustained Delivery of a Shingles Subunit Vaccine Overcomes Age‐Related Declines in Humoral and Cellular Immunity Relative to Shingrix

open access: yesAdvanced Science, EarlyView.
Sustained delivery of a shingles subunit vaccine from an injectable polymer–nanoparticle hydrogel enhanced the potency, durability, and breadth of immune responses in aged mice while minimizing inflammatory cytokine production and reactogenicity. This strategy decouples immunogenicity from reactogenicity and offers a promising approach to improve ...

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

open access: yesAngewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

open access: yesAdvanced Science, EarlyView.
Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

open access: yesAdvanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.
