Fabrication Of Superparamagnetic And Ferromagnetic Nanoparticles
(Physics, 2009-09-16)
Monodisperse magnetic nanoparticles with controlled size and geometry have drawn great attention in the last decade for fundamental scientific studies and for their potential applications in advanced materials and devices ...
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 ...
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 ...
First Observation Of Dijet Events With An Antiproton Tag At [square root]s = 1.96 TEV Using The DØ Forward Proton Detector
(Physics, 2007-08-23)
The Forward Proton Detector (FPD) is a new sub-system of the DØ detector, a 5000 ton particle physics detector located at the Fermilab Tevatron proton-antiproton collider. The FPD was implemented for the Tevatron Run II ...
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 ...
First Direct Measurement Of The Energy Spectra Of Individual Auger Cascade Steps In Solid MnO, Ag And Pd
(Physics, 2007-09-17)
We present the first direct measurements of energy spectra of electrons emitted in the later steps of the Auger cascade processes in solids. Measurements were carried out for the L-->MV-->VVV and L-->MM-->MVV-->VVVV Auger ...
Study Of Oxide Surfaces Using Time Of Flight Positron Annihilation Induced Auger Electron Spectroscopy
(Physics, 2007-08-23)
Transition metal oxides (TMOs) exhibit a rich collection of interesting and intriguing properties which can be used for wide variety of applications. In this dissertation, I will discuss the first PAES measurements on ...
Electron Emission From Surfaces Resulting From Low Energy Positron Bombardment
(Physics, 2009-09-16)
Measurements of the secondary electron energy spectra resulting from very low energy positron bombardment of a polycrystalline Au and Cu (100) surfaces are presented that provide evidence for a single step transition from ...
Simulations Of High-latitude Ionosphere-magnetosphere region plasma density structures and the Alfvén waves effects
(Physics, 2009-09-16)
O+ density structures in the polar cap ionosphere-magnetosphere region near 6000 km altitude have been observed with numerous spacecraft, with O+ densities ranging from above 10 cm-3 to lower than 0.01 cm-3. Regions with ...
