Nanophotonics may usher in a host of radical advances, including powerful “hyperlenses” resulting in sensors and microscopes 10 times more powerful than today’s and able to see objects as small as DNA; computers and consumer electronics that use light instead of electronic signals to process information; and more efficient solar collectors. Spaser stands for surface …
1. Magnetic Silicon Fullerene A magnetic metal-encapsulating silicon fullerene, Eu@Si20, has been predicted by density functional theory to be by far the most stable fullerene-like silicon structure. The Eu@Si20 structure is a regular dodecahedron with Ih symmetry in which the europium atom occupies the center site. The calculated results show that the europium 10 atom …
A robot, smaller than one millimeter, has been built by Korean scientists to travel through blood vessels Once inside a blocked artery, it is able to release drugs to dissolve blood clots, which are often the cause of heart attacks. The robot has three short front legs and three longer back legs which are attached …
