Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give .
The Horse Head Nebula is a cloud of ionized- hydrogen in the constellation Orion. The clouds are lit from within by young hot stars. The interstellar dust absobs the light from part of ionized cloud creating this beautiful contrast
