Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging

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 robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Graphene layers dramatically reduce wear and friction on sliding steel surfaces

Scientists at Argonne National Laboratory have recently discovered that they could substitute one-atom-thick graphene layers for oil-based lubricants on sliding steel surfaces, enabling a dramatic reduction in the amount of wear and friction.

How Could Light-emitting Monolayers Benefit Soldiers?

U.S. Army scientists want to make sense of the fascinating properties of novel layered materials that can exist in a single or a few atom-thick layers, such as graphene.

The tiny red spot in this image is one of the most efficient star-making galaxies ever observed, converting gas into stars at the maximum possible rate. The galaxy is shown here in an image from NASA's Wide-field Infrared Survey Explorer (WISE), which first spotted the rare galaxy in infrared light.
