Foam offers way to manipulate light

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by scientists is able to block particular wavelengths of light, a coveted property for next-generation ...

An overlooked piece of the solar dynamo puzzle

A previously unobserved mechanism is at work in the Sun's rotating plasma: a magnetic instability, which scientists had thought was physically impossible under these conditions. The effect might even play a crucial role in ...

Theory reveals the nature of silicon carbide crystals defects

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide ...

Scientists develop filter to suppress radio interference

Researchers from Siberian Federal University and Kirensky Institute of Physics have proposed a new design for a multimode stripline resonator. The use of such resonators allows scientists to create miniature band-pass filters ...

Nanogenerator's 2500% stretchability sets new record

By stretching like a rubber band to more than 25 times its original length, a new nanogenerator has set a new stretchability record. The triboelectric nanogenerator's 2500% stretchability represents a significant increase ...
