Scientists developed a device capable of controlling magnetism at a lower current level than conventional spintronics devices. The new device was fabricated by combining a solid electrolyte with a magnetic material, and enabling insertion/removal of ions into/from the magnetic material through application of voltage.

Washington State University researchers have developed a unique, multifunctional smart material that can change shape from heat or light and assemble and disassemble itself. This is the first time researchers have been able to combine several smart abilities, including shape memory behavior, light-activated movement and self-healing behavior, into one material.

Smart materials that can react to external stimuli, like light or heat, have been an interesting novelty and look almost magical as they mysteriously fold and unfold themselves...

~Clue to development of light-weighted, flexible, high-contrast lighting. An international joint research group succeeded in developing a novel thermally activated delayed fluorescence (TADF) material which displays emission of light in colors from green to deep-red through Intersystem Crossing from the singlet to the triplet excitons, a world first. The results will contribute to R&D in white TADF light emitting devices for indoor and outdoor use through combination with TADF materials that emit light in shorter wavelengths (deep blue to yellow).

Over the last few decades, research on organic light-emitting diodes (OLEDs) has greatly advanced...

Rutgers University engineers created unique elastomeric rotary actuators based on pneumatically driven peristaltic motion. Using silicone-based wheels, these motors enable a new class of soft locomotion — not found in nature — that can withstand impact, traverse irregular terrain and operate in water. For soft robotics, this innovation represents progress toward providing torque without bending actuators. Credit: Xiangyu Gong

Rutgers engineers, in a breakthrough, create a soft motor that could power versatile soft robots. A small, squishy vehicle equipped with soft wheels rolls over rough terrain and runs under water...
