Structural and chemical disorder near the Y₂BaCuO₅/YBa₂Cu₃O₇-δ interface and its possible relation to the flux-pinning behavior in melt-textured YBa₂Cu₃O₇-δ
(Georgia Institute of Technology, 1993-03-01)
Transmission-electron microscopy and energy-dispersive x-ray spectroscopy were used to study the microstructure of the YBa₂Cu₃O₇-δ (1:2:3) region adjacent to the Y₂BaCuO5/YBa₂Cu₃O₇-δ (2:1:1/1:2:3) interface. It is found ...
Plasmon energy shift in mesoporous and double length-scale ordered nanoporous silica
(Georgia Institute of Technology, 1999-05-03)
Electron energy-loss spectroscopy studies are reported on three different types of structures: solid silica spheres, mesoporous silica, and the double length-scale ordered (DLSO) porous silica. The mesoporous silica has ...
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: ...
Effects of Microstructure on Crack Initiation in AA6451 and Crack Propagation in AA3xxx
(Georgia Institute of Technology, 2020-03-31)
Aluminum alloys have been enjoying the spotlight in recent years as the next generation alloy for a wide variety of applications. Their potentially waste-free recyclability, excellent corrosion resistance, and desirable ...
