Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Monolithic 3D Printing of Origami‐Inspired Soft Robotics from Sustainable Bio‐Based Resin

Advanced Science, EarlyView.
This work develops a photocurable, bio‐based resin from soybean oil for the monolithic fabrication of sustainable soft robots via Digital Light Processing. An origami‐inspired, vacuum‐actuated soft gripper is designed and fabricated, enabling reliable operation despite the material's lower elongation.

Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery

Advanced Science, EarlyView.
This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...
