What do you get if you combine nanotextured 'Cassie' surfaces with the Leidenfrost effect? Highly water-repellent surfaces that show potential for developing future self-cleaning windows, windshields, exterior paints and more.
There's a lot of stuff you'd expect to find in baby formula: proteins, carbs, vitamins, essential minerals. But parents probably wouldn't anticipate finding extremely small, needle-like particles. Yet this is exactly what a team of scientists recently discovered.
Researchers have directly detected the Peltier effect in graphene. They showed that the effect can be switched from heating to cooling by tuning the type and density of the charge carriers inside the material.
A new electronic material created by an international team can heal all its functions automatically even after breaking multiple times. This material could improve the durability of wearable electronics.
Scientists describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.
Researchers have programmed polarization into compact holograms. These holograms use nanostructures that are sensitive to polarization (the direction in which light vibrates) to produce different images depending on the polarization of incident light.
