Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes
Advanced Functional Materials, EarlyView.Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Air Permeability of Pantyhose Fabric.
Sen'i Kikai Gakkaishi (Journal of the Textile Machinery Society of Japan), 2000 To clarify differences in air permeability of the hose cloth of different types of pantyhose on the market in Japan, cylindrical model experiments and wearing experiments were conducted. The former was made to determine fundamental performance of the air permeability, and the latter, to evaluate the practical performance of worn pantyhose.
