چکیده
Abstract Harvesting electricity from ubiquitous atmospheric moisture has drawn growing research attention. Despite great advances, generators still suffer performance decay during long‐term service. Recently, self‐oscillating actuators driven by humidity gradience have attracted interests, which may give a clue to harvest energy persistently via electromagnetic induction. In order combine high electric conductivity with actuators, bimorph composites of 2D conductive MXene liquid metal (i.e., EGaIn) are designed. presence marine alginate, EGaIn droplets can be encapsulated nanosheets in their suspension. And simple liquid‐casting produce biomorph actuating films top MXene‐rich layer and bottom EGaIn‐rich self‐sintered droplets. When exposing (e.g., 20% cm −1 ), this actuator oscillate an speed ≈260° s frequency ≈0.5 Hz, while without any human intervention. Under magnetic field intensity T), behavior generate alternating faradic current amplitude at least 1360 µA m −2 . Thus, study not only provide alternative pathway for producing but also offer new strategy persistent moisture.

Microstructure and property of TiB-reinforced Ti alloy composites by laser metal deposition
TiB-reinforced Ti alloy composites have been laser deposited with pre-alloyed Ti-6Al4V-1B powder. The microstructure of the as-deposited and heat treated composites have been characterized in detail using scanning electron microscope (SEM). A homogeneous dispersion of needle-like TiB precipitates is formed in the Ti-6Al-4V α/β matrix. TiB precipitates promote formation of small near equaxed α/β...

15 صفحه اولMechanochemical Mechanism for Fast Reaction of Metastable Intermolecular Composites Based on Dispersion of Liquid Metal
A new mechanism for fast reaction of Al nanoparticles covered by a thin oxide shell during fast heating is proposed and justified theoretically and experimentally. For nanoparticles, the melting of Al occurs before oxide fracture. The volume change due to melting induces pressures of 1–2 GPa and causes dynamic spallation of the shell. The unbalanced pressure between the Al core and the exposed ...
