In vitro Biomimetic Construction of Hydroxyapatite–Porcine Acellular Dermal Matrix Composite Scaffold for MC3T3-E1 Preosteoblast Culture
(Georgia Institute of Technology, 2011-02-26)
The application of porous hydroxyapatite–collagen (HAp-Collagen) as a bone tissue engineering scaffold is hindered by two main problems: its high cost and low initial strength. As a native 3-dimenssional collagen framework, ...
Combined polarized Raman and atomic force microscopy: In situ study of point defects and mechanical properties in individual ZnO nanobelts
(Georgia Institute of Technology, 2009-08-04)
We present a method, polarized Raman (PR) spectroscopy combined with atomic force microscopy (AFM), to characterize in situ and nondestructively the structure and the physical properties of individual nanostructures. ...
Erratum: Effects of piezoelectric potential on the transport characteristics of metal-ZnO nanowire-metal field effect transistor
(Georgia Institute of Technology, 2009-08-03)
Collective oscillations in a single-wall carbon nanotube excited by fast electrons
(Georgia Institute of Technology, 2001-08-31)
Electron energy loss spectroscopy is a well adapted tool for the investigation of the valence excitations of individual nanometer-size particles. The interpretation of the loss spectra of such small particles, however, ...
Plasmon excitations in graphitic carbon spheres
(Georgia Institute of Technology, 1998-06-15)
Electron energy loss spectroscopy in a high-resolution transmission electron microscope has recently been used with success to characterize the electronic properties of closed cage nanometer-size graphitic particles. In ...
Ordered Self-Assembling of Tetrahedral Oxide Nanocrystals
(Georgia Institute of Technology, 1997-09-29)
Self-assembling of size, shape, and phase controlled nanocrystals into superlattices with translational and even orientational ordering is a new approach for engineering nanocrystal materials and devices. High purity ...
Analysis of Cation Valences and Oxygen Vacancies in Magnetoresistive Oxides by Electron Energy-Loss Spectroscopy
(Georgia Institute of Technology, 1998)
Magnetic oxides of (La,A)MnO₃ and (La,A)CoO₃ have two typical structural characteristics: cations with mixed valences and oxygen vacancies, which are required to balance the charge introduced by cation doping. The ...
Plasmon excitations in carbon onions: Model vs. measurements
(Georgia Institute of Technology, 1998-03)
Non-relativistic local dielectric response theory has proven successful in the interpretation of Electron Energy Loss data of nanometer-size isotropic particles of different geometries. In previous work, we have adapted ...
Microstructural effects on surface mechanical properties of ion-implanted polymers
(Georgia Institute of Technology, 1993-04)
Tefzel, a copolymer of tetrafluoroethylene and ethylene, was implanted simultaneously with 400 keV boron, 700 keV nitrogen, and 600 keV carbon to a dose of 3 X 10¹⁵ ions/cm² for each ion. The implanted layer was examined ...
Optimum experimental conditions for quantitative surface microanalysis by reflection electron energy-loss spectroscopy
(Georgia Institute of Technology, 1991-04)
Experimental conditions for obtaining high quality core-shell ionization edges in reflection electron energy-loss spectroscopy (REELS) are investigated. Under the (600) specular- "mirror" reflection conditions and using ...
