Breaking the Toughness‐Stretchability Trade‐Off in Hydrogels with Dynamic Hydrogen Bonding

Advanced Science, EarlyView.
A novel nanocomposite hydrogel architecture overcomes the inherent conflict between toughness and stretchability by integrating uniformly dispersed aminopropyl‐hybrid‐phyllosilicate nanosheets within a polyacrylamide matrix. This design leverages a dynamic hydrogen‐bonding network to facilitate efficient energy dissipation and self‐recovery.

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Characterization of Biominerals in Cacteae Species by FTIR

Crystals, 2020
A biomineral is a crystalline or amorphous mineral product of the biochemical activity of an organism and the local accumulation of elements available in the environment. The cactus family has been characterized by accumulating calcium oxalates, although

La synthèse thermique des silicates de calcium

, 1953
The work described here was carried out in order to determine the action of CaO on SiO2 by raising the temperature of mixtures of these oxides. For this, samples containing CaCO3 and amorphous SiO2, or, Ca(OH)2 and amorphous SiO2 were prepared.

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

Advanced Science, EarlyView.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.
