Confined nanoscale sound controls light in a microresonator

When traversing a solid material such as glass, a light wave can deposit part of its energy in a mechanical wave, leading to a color change of the light. This process, called "Brillouin scattering," has important technical ...

How to program materials

Ali Gooneie simulates on his computer what holds the world together right at its very core: atoms, molecules, molecular chains and bundles—then lumps and fibers, which emerge from these. With his calculations, the Empa ...

Simulating and optimizing industrial spinning processes

Spinning polymer filaments, for example for personal care articles, is highly complex: simulating the processes involved is too much for currently available computing power to handle. Fraunhofer researchers have successfully ...

'Exotic' genes may improve cotton yield and quality

Cotton breeders face a "Catch-22." Yield from cotton crops is inversely related to fiber quality. In general, as yield improves, fiber quality decreases, and vice-versa. "This is one of the most significant challenges for ...

New quick-fix wrap can repair and reinforce existing structures

By protecting concrete pillars with a ready-to-stick wrap developed by Nanyang Technological University, Singapore (NTU Singapore) and JTC, existing structures can be easily repaired and reinforced to extend their lifespan. ...

Lobster's underbelly is as tough as industrial rubber

Flip a lobster on its back, and you'll see that the underside of its tail is split in segments connected by a translucent membrane that appears rather vulnerable when compared with the armor-like carapace that shields the ...

Anti-fatigue-fracture hydrogels

Hydrogels are polymer networks infiltrated with water, widely used for tissue engineering vehicles of drug delivery and novel platforms for biomedical engineering. Emerging applications for new hydrogel materials call for ...

A sustainable and recyclable thermoelectric paper

Thermoelectric materials, capable of transforming heat into electricity, are very promising for converting residual heat into electrical energy, as they convert hardly usable or nearly lost thermal energy in an efficient ...
