Grain size dependence of magnetic properties in shock synthesized bulk Pr₂Fe₁₄B/α-Fe nanocomposites
(Georgia Institute of Technology, 2004-09-15)
The structural and magnetic properties of the melt-spun Pr₂Fe₁₄B/α-Fe nanocomposite powders consolidated via shock-wave compression and subjected to postshock thermal treatment were investigated. Shock compression results ...
Manganese-doped ZnO nanobelts for spintronics
(Georgia Institute of Technology, 2004-02-02)
Zinc oxide (ZnO) nanobelts synthesized by thermal evaporation have been ion implanted with 30 keV Mn+ ions. Both transmission electron microscopy and photoluminescence investigations show highly defective material directly ...
Temperature driven in-situ phase transformation of PbWO₄ nanobelts
(Georgia Institute of Technology, 2011-06-23)
Monoclinic raspite PbWO₄ nanobelts were synthesized by a facile composite-salt-mediated method. By in situ heating to above 538 °C inside the chamber of a transmission electron microscope, the raspite nanobelts transformed ...
Structural colors from Morpho peleides butterfly wing scales
(Georgia Institute of Technology, 2009-10-12)
A male Morpho peleides butterfly wing is decorated by two types of scales, cover and ground scales. We have studied the optical properties of each type of scales in conjunction with the structural information provided by ...
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 ...
Interface and defect structures of Zn–ZnO core–shell heteronanobelts
(Georgia Institute of Technology, 2004-01-01)
Interface and defect structures of Zn–ZnO core–shell nanobelts have been investigated using high-resolution transmission electron microscopy. Most of the nanobelts can be classified into two types from their growth directions: ...
