Left: Electrons moving through a short, narrow nano wire experience this as a trip through a mountain pass. Right: Electron microscope image of the device with an adjustable nano wire. Electrons move from left to right under the surface of a semiconductor (dark). The precise shape of the nano channel can be set by applying an electrical voltage to the electrodes on the surface.

This mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the scene from the rover's position on the 376th Martian day, or sol, of the mission (Aug. 27, 2013). The images were taken right after Curiosity completed the first drive during which it used autonomous navigation on unknown ground.

Size Matters as Nanocrystals Go Through Phases: Berkeley Lab Researchers at the Molecular Foundry Reveal Fundamental Size-Dependence of Metal Nanocrystals Undergoing Phase Transitions

Understanding what happens to a material as it undergoes phase transformations - changes from a solid to a liquid to a gas or a plasma - is of fundamental scientific interest and critical for optimizing commercial applications. For metal nanocrystals, assumptions about the size-dependence of phase transformations were made that now need to be re-evaluated.

48048.jpgPalladium nanocubes interacting with hydrogen gas were directly observed through in situ luminescence to reveal that size can make a much bigger difference on phase transformations than scientists previously believed.
