Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...
