New experiments confirm for the first time that the hydrogen bonds that hold together groups of water molecules possess part of the identity of the bonds that exist within a water molecule. The first microscopic images, in real space, of a superconductor near the precise moment at which it loses its ability to carry current without electrical resistance. Changes in the polarization of reflected light can reveal the stresses between interacting disks in a two-dimensional granular material. Stacked organic LEDs can now produce full color. False-color image of turbulence in a soap film.
Newton rings reveal laser ablation on a picosecond scale.
A transistor based on a single, nanometer-scale molecule composed of carbon atoms. In this image, electron waves are seen to be breaking around two atom-sized defects. A computer simulation of the view down a boron-nitride nanotube. A transistor that exploits an electron's ability to pass through normally insurmountable energy barriers. A microscope determines whether nanoscopic tubes of carbon are metallic or semiconducting.
