Bowtie-shaped Nanostructures may advance development of Quantum devices. Made of silver, these may help bring the dream of quantum computing and quantum information processing closer to reality. They greatly simplify the experimental conditions for studying quantum phenomena and may one day be developed into crucial components.

Led by Prof. Gilad Haran of Weizmann’s Chemical Physics Department the team manufactured 2D bowtie-shaped silver nanoparticles with a minuscule gap of about 20 nanometers in the center...

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...

Thermally Activated Delayed Fluorescence Process in OLED Devices Credit: Osaka University

~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...
