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 ...
Nanoscale mechanical behavior of individual semiconducting nanobelts
(Georgia Institute of Technology, 2003-08-04)
Nanobelts are a group of materials that have a rectangle-like cross section with typical widths of several hundred nanometers, width-to-thickness ratios of 5–10, and lengths of hundreds of micrometers. In this letter, ...
Thermal conductivities of individual tin dioxide nanobelts
(Georgia Institute of Technology, 2004-04-05)
We have measured the thermal conductivities of a 53-nm-thick and a 64-nm-thick tin dioxide (SnO₂) nanobelt using a microfabricated device in the temperature range of 80–350 K. The thermal conductivities of the nanobelts ...
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 ...
