Abstract

One gram of tungsten nanowires - equivalent to 5 billion single wires - was produced by electrochemically processing a directionally solidified eutectic NiAl-W alloy. Their release is realised by selective dissolution of the matrix with a yield beyond 98%. The nanowires are single crystals, homogeneous in diameter, and have extremely high aspect-ratios (>1000!). A multitude of potential applications are feasible - including sensing, probing, and high temperature nanotechnology.
