• Nanowires grown on graphene have surprising structure
  

  When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for m more

• Secret of the crystal's corners
  

  New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with somethin more

• Parallelogram shaped nanowires control light in two dimensions

  A novel zinc oxide microwire optical resonator with parallelogram-shaped cross section has been made by chemists. The material can effectively control light in two dimensions, and could play the part of a building block in the development of optoelectronic devices.   more

• Low-Cost SnSx Counter Electrodes for Dye-Sensitized Solar Cells

  SnS nanosheets (NSs), SnS nanowires (NWs) and SnS2 nanosheets were synthesized and investigated as counter electrode (CE) catalysts in a I3-/I- based dye-sensitized solar cells (DSCs) system for the first time. It is found that the SnS NSs based DSCs show comparable power-conversion efficiency (Eff more

• Nanoscale Piezoelectric Response of ZnO Nanowires by a Nanoindentation Technique

  We report the piezoelectric properties of ZnO nanowires (NWs) obtained by using a nanoindenter with a conductive boron-doped diamond tip. The direct piezoelectric effect was measured by performing nano-indentations under load control, and the generated piezoelectric voltage was characterized as a fu more

• Unusual growth direction and controllable wettability of W-catalyzed AlN nanowires

  Metal W is firstly employed as an efficient catalyst to grow the AlN nanowires. High-density nanowires have been synthesized with W catalyst cap at the tip. Transmission electron microscopy further reveal that the W-catalyzed AlN nanowires have an unusual [1 0 1] growth direction. The growth process more
