The improved low‐field electro‐actuation of dielectric elastomer composites regulated by entirely‐inorganic BaTiO 3 @ TiO 2 core‐shell construction

Abstract Dielectric elastomer (DE) as an important electro‐active polymer (EAP), is capable of providing a large elastic deformation under an external electric field. However, the excellent electro‐actuated performance is usually obtained under high…

Efficient industrial-current-density acetylene to polymer-grade ethylene via hydrogen-localization transfer over fluorine-modified copper

Abstract Electrocatalytic acetylene semi-hydrogenation to ethylene powered by renewable electricity represents a sustainable pathway, but the inadequate current density and single-pass yield greatly impedes the production efficiency and industrial…

Direct Observation of Transition Metal Ions Evolving into Single Atoms: Formation and Transformation of Nanoparticle Intermediates

Abstract Understanding the dynamical evolution from metal ions to single atoms is of great importance to the rational development of synthesis strategies for single atom catalysts (SACs) against metal sintering during pyrolysis. Herein, an in situ…

Hybrid infrared-visible multiview correlation to study damage in a woven composite complex-shaped specimen

In this study, a cyclic tensile test on a notched butterfly specimen made of woven glass fiber composite was performed on a modified Arcan fixture. During the mechanical test, the sample was monitored with a hybrid stereoscopic system comprised of…

4D full-field measurements over the entire loading history: Evaluation of different temporal interpolations

Standard Digital Volume Correlation (DVC) approaches are based on pattern matching between two reconstructed volumes acquired at different stages. Such frameworks are limited by the number of scans (due to acquisition duration), and time-dependent…
