Oligomerization‐Induced Supramolecular Glass with Superior Processability and Optical Functions

Advanced Optical Materials, EarlyView.
Oligomerization‐induced supramolecular glass (BGG) is formed via a catalyst‐free melt‐quenching strategy from benzoguanamine. The in situ formation of diverse oligomers suppresses crystallization, enabling glass formation. BGG exhibits a high Tg (100.1 °C), polymer‐like modulus, and bright aggregation‐induced emission, and is readily processed into ...

Fully Plant‐Based and Optically Transparent Wood Substrates with Improved Thermal Insulating Properties

Advanced Sustainable Systems, EarlyView.
The combination of an eco‐friendly bleaching procedure with the use of a new commercial bio‐based resin used to develop transparent wood (TW) result in a transparency level of 91% at 550 nm, alongside remarkable stability and a ≈50% reduction in thermal conductivity compared to standard glass (≈1 W m·K−1), highlighting its potential as energy‐efficient

Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome

Advanced Science, EarlyView.
Shear‐activated nanoparticles carrying nitroglycerin selectively target high‐shear stress collateral vessels during ischaemic stroke, enhancing blood flow to at‐risk brain without systemic side effects. This novel approach significantly improves outcomes in animal models, outperforming conventional nitroglycerin delivery.

Smart Gated Hollow Mesoporous Silica Hydrogel for Targeting Endoplasmic Reticulum Stress and Promoting Periodontal Tissue Regeneration

Advanced Science, EarlyView.
The hollow mesoporous silica loaded with quercetin (HM‐QU@PEG) is combined with a thermosensitive anti‐bacterial matrix (TF127) to prepare HQUP@TF127. HQUP@TF127 effectively eliminates excessive ROS, alleviates endoplasmic reticulum stress, relieves mitochondrial calcium overload, and blocks the p53‐dependent apoptotic cascade. Furthermore, it enhances
