Mechanical behavior and magnetic separation of quasi-one-dimensional SnO₂ nanostructures: A technique for achieving monosize nanobelts/nanowires
(Georgia Institute of Technology, 2005-03-25)
The as-synthesized nanowires and nanobelts usually have a large size distribution. We demonstrate here a ball milling technique for narrowing the size distribution of oxide nanobelts and nanowires. High-resolution scanning ...
Controlled synthesis and manipulation of ZnO nanorings and nanobows
(Georgia Institute of Technology, 2005-01-19)
An experimental procedure is presented for the controlled synthesis and manipulation of ZnO nanorings and nanobows at high purity and large yield. Atomic force microscopy manipulation of the nanostructures demonstrates ...
Integration of metal oxide nanobelts with microsystems for nerve agent detection
(Georgia Institute of Technology, 2005-01-31)
We have assembled tin dioxide nanobelts with low-power microheaters for detecting dimethyl methylphosphonate (DMMP), a nerve agent simulant. The electrical conductance of a heated nanobelt increased for 5% upon exposure ...
Nanoarchitectures of semiconducting and piezoelectric zinc oxide
(Georgia Institute of Technology, 2005-01-21)
Semiconducting and piezoelectric zinc oxide has two important structure characteristics: the multiple and switchable growth directions: 010, 20, and 0001; and the {0001} polar surfaces. The fast growth directions create ...
Carbon Nanotubes: Chemical Vapor Deposition Synthesis and Application in Electrochemical Double Layer Supercapacitors
(Georgia Institute of Technology, 2005-03-08)
Carbon nanotubes (CNTs) have become a popular area of materials science research due to their outstanding material properties coupled with their small size. CNTs are expected to be included in a wide variety of applications ...
