Advanced Materials, EarlyView.A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Al2O3 Ring Array by Infiltration Synthesis in Polystyrene Antidot Template
Advanced Materials Interfaces, EarlyView.Different morphologies, such as full dots for genuine PS‐b‐PMMA, residual dots for the PS antidot array (resulting from an Acetic Acid (AA) last PS‐b‐PMMA), and rings for the modified PS antidot array (derived from an O2 plasma last PS‐b‐PMMA), originated from SIS process in PS‐b‐PMMA BCP array, due to the different reaction sites for the TMA precursor

Advanced Materials Technologies, EarlyView.A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.
