The average, everyday person might not be familiar with gallium nitride, also known as GaN, but there is a good chance they've heard of silicon, a semiconductor that's been used for decades and found in every computer and most electronics.
When oil mixes with or enters into water, conventional methods of cleaning the water and removing the oil can be challenging, expensive and environmentally risky. But researchers believe they may have developed a better method.
The endothelial cells that line blood vessels are packed tightly to keep blood inside and flowing, but scientists have discovered it may be possible to selectively open gaps in those barriers just enough to let large molecules through - and then close them again.
Instead of using a train of soliton pulses in an optical fiber, researchers generated continuously circulating optical solitons in compact silicon nitride optical microresonators. These continuously circulating solitons lead to broadband optical frequency combs.
Researchers have found that crystallization can be facilitated at a lower temperature than the traditional transition temperature if an amorphous material is agitated at a certain frequency. Thus, agitation represents a possible alternative to temperature for controlling the crystallization of materials.
Scientists have developed new imaging methods that allows them to track the individual protein molecules on the surface of cells. The results offer unprecedented insight into how cells sense and respond to their environments.
Researchers have for the first time discovered magnetism in the 2-D world of monolayers, or materials that are formed by a single atomic layer. The findings demonstrate that magnetic properties can exist even in the 2-D realm - opening a world of potential applications.
A research team has made the first images of half-light, half-matter quasiparticles called exciton-polaritons. The discovery could be an early step to developing nanophotonic circuits that are up to 1 million times faster than current electrical circuits.
