The Synthesis And Luminescence Properties Of Lanthanide-based Nanoparticles For Biological Application
(Physics, 2008-09-17)
Lanthanide-doped nanoparticles have great potential as a new kind of luminescent material. In this thesis, we report the synthesis of Cerium-doped LaF3 nanoparticles in dimethyl sulfoxide (DMSO) using chemical reaction at ...
Plasmonic Nanostructures: Fabrication And Optical Characterization
(Physics, 2008-09-17)
Resonant light localization by metal nanostructures has potential for applications in cavity quantum electrodynamics (e.g. single-photon sources, quantum gates etc) and nonlinear optics.
In this thesis we present the ...
Semi-empirical Studies Of Solar Supergranulation And Related Phenomena
(Physics, 2008-09-17)
In recent years, solar observations have moved from ground-based
telescopes to observatories on Earth orbiting satellites, such as
SOHO. They provide us with a clear and uninterrupted view of the
solar disk. One instrument ...
A Search For The Higgs Boson In Its Associated Production With A W Vector Boson in p¯p Collisions at √s = 1.96 TeV
(Physics, 2008-04-22)
We present the results of a search for the Standard Model Higgs boson in its associated
production with a W vector boson in p¯p collisions at √s = 1.96 TeV using the complete Run
IIA dataset with an integrated luminosity ...
Silicon Carbide Nanotubes: Promises Beyond Carbon Nanotubes
(Physics, 2008-09-17)
First-principles calculations for the electronic and geometric structures of three different types of armchair and zigzag silicon carbide nanotubes from (3, 3) to (11, 11) and (3, 0) to (11, 0) have been performed using ...
First-principles Study On Hard/soft SmCo5/Co(Fe) Nanocomposite Magnetic Materials
(Physics, 2008-09-17)
More than a decade ago, exchange-spring permanent magnets containing soft and hard magnetic phases have been proposed to enlarge maximum energy product values through exchange coupling between the magnetically soft and ...
Germanium Based Nanotubes: Fact Or Fiction?
(Physics, 2008-09-17)
Unlike carbon nanotubes, nanostructures of Ge, a group IV semiconductor, have not been fully explored. In particular, there is limited data available on Germanium-based nanotubes. The aim of this thesis is to explore the ...
Probing The 5f Electrons: A Relativistic DFT Study Of Americium Surfaces
(Physics, 2008-09-17)
Surface chemistry and physics have been and continues to be very active fields of research because of the obvious scientific and technological implications and consequent importance of such research. One of the many ...
Rapid thermal annealing of FePt nanoparticles
(American Institute of Physics, 2008-07-11)
We report a systematic study on rapid thermal annealing (RTA) of FePt nanoparticles. FePt particles with an average size of 8 nm were synthesized by a chemical solution method, and then annealed using RTA and conventional ...
First-principles prediction of enhanced magnetic anisotropy in FeCo alloys
(American Institute of Physics, 2008-02-04)
The structural, electronic, and magnetic properties of FeCo alloys were studied by first-principles calculations. It has been found that the alloys prefer chemically noncubic geometries in a wide composition range. This ...
