Physicists from MIPT have predicted the existence of transparent composite media with unusual optical properties. Using graphics card based simulations, scientists studied regular volume structures composed of two dielectrics with close parameters, and found that the optical properties of these structures differ from both those of natural crystals ...

Metamaterials don't exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a world of possibilities. Formed by nanostructures that act as "atoms," arranged on a substrate to alter light's path in ways no ordinary ...

Magnetic balls provide exciting avenues for exploring many fundamental phenomena in physics. They can be assembled by hand into chains and more complex structures and used to model the properties of unstretchable materials that, like paper, crumple under certain loading conditions. Magnetic balls stacked on top of each other into vertical chains remain stable ...

There have been many attempts to modify this stubborn little enzyme, but none have succeeded. Until now. With new findings from Chalmers University of Technology, the fatty acid synthase (FAS) enzyme has started to produce sustainable chemicals for biofuels. The results were recently published in the journal Nature Chemical Biology ...

Polymer nanocomposites mix particles billionths of a meter (nanometers, nm) in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer ...

Georgia Institute of Technology researchers have demonstrated an optical metamaterial whose chiroptical properties in the nonlinear regime produce a significant spectral shift with power levels in the milliwatt range. The researchers recently demonstrated properties of ...

A fusion reactor is essentially a magnetic bottle containing the same processes that occur in the sun. Deuterium and tritium fuels fuse to form a vapor of helium ions, neutrons and heat. As this hot, ionized gas -- called plasma -- burns, that heat is transferred to water to make steam to turn ...

If someone asks you to hand them a wrench from a table full of different-sized wrenches, you’d probably pause and ask, “which one?” Robotics researchers from Brown University have now developed an algorithm that lets robots do the same thing — ask for clarification when they’re ...

The bubbles that form on a heated surface create a tiny recoil when they leave it, like the kick from a gun firing blanks. Now researchers at the University of Illinois at Chicago, under funding from NASA, have shown how this minuscule force can be harnessed to mix liquid coolant around ...
