Self‐Healing and Reprocessable Soft Robots Using 3D Digital Light Printing

open access: yesAdvanced Science, EarlyView.
This work advances 3D digital light printing of soft robots made from self‐healing, recyclable elastomers enabled by dynamic covalent bonds. With the introduction of room‐temperature healing, these robots recover their mechanical performance (94.5% static, 87.5% dynamic) after damage and maintain their functionality.

Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

open access: yesAdvanced Science, EarlyView.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Comparing Nutrient Intake by Wolf Spiders (Hogna carolinensis) Consuming Frogs (Acris blanchardi) and Crickets (Gryllodes sigillatus)

open access: yesEcology and Evolution
Herbivores and omnivores have been shown to regulate their intake of nutrients to a balance that maximizes fitness. Predators were traditionally believed to have less need for dietary regulation than herbivores, given the higher nutritional quality of ...

XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.
