World's Fastest Photo-Exfoliation

World's Fastest Photo-Exfoliation Osaka City University discovers world‘s fastest exfoliation of material with potential use for photoactuator production. Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the compound peels off into micrometer sized crystals at a world’s fastest speed of 260 microseconds. As the material returns to its former molecular structure when exposed to visible light, the exfoliation method positions itself as a candidate for photoactuator manufacturing. Look at any piece of machinery and you will see a complex network of moving parts, or actuators, each with its own function, all working together for a common goal. From this perspective, the way most machines differ is in the way their actuators are powered: excavators rely on compressed liquid (hydraulic), the brake system in a car uses compressed air (pneumatic), and a printer has electricity.
