Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

open access: yesAdvanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

Adaptive anti-jamming scheme based on meta-surface antenna

open access: yesDianxin kexue
Aiming at the problem that traditional anti-jamming schemes cannot choose suitable anti-jamming strategies according to different types of jamming forms, an adaptive anti-jamming scheme based on meta-surface antenna was proposed.

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.
