Red‐to‐Blue Upconversion Nanoparticles Catalyze Aqueous Radical Polymerization

open access: yesAdvanced Optical Materials, EarlyView.
Encapsulation of a red‐to‐blue upconversion pair into polymer nanoparticles gives water‐stable heterogeneous nanocatalysts with distinguished stability. Red light irradiation of these nanocatalysts initiates aqueous polymerization of a series of acrylates with high conversion yields.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.
