Shape‐Changing Multiphase Microparticles from Complex Liquid Crystal Emulsions

Advanced Functional Materials, EarlyView.
Liquid crystalline network (LCN) microparticles are prepared from single, double (Janus), and triple emulsions through a simple and scalable bulk‐emulsification strategy. Under heating, the particles exhibit robust, reversible, large‐amplitude deformations that depend both on the morphology and the liquid crystals director field configuration.

A Second Order Perturbation Solution of a Non-Collinear Crack And Its Application to Crack Path Prediction of Brittle Fracture in Weldment

A Second Order Perturbation Solution of a Non-Collinear Crack And Its Application to Crack Path Prediction of Brittle Fracture in Weldment
Stress intensity factors are analyzed for a non-collinear crack by using a second order perturbation method. The method is extended to obtain an approximate representation of stress intensity factors at the tip of a straight crack with a slightly branched and curved extension.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding

Advanced Functional Materials, EarlyView.
A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...
