Anisotropic nanostructured magnets by magnetic-field-assisted processing
(American Institute of Physics, 2010-04-15)
It has been a great challenge to produce anisotropic nanocrystalline bulk magnets. In this paper, we report our recent work in preparing anisotropic bonded magnets consisting of SmCo5 nanocrystalline particles. The work ...
Effects of particle size and composition on coercivity of Sm–Co nanoparticles prepared by surfactant-assisted ball milling
(American Institute of Physics, 2010-04-15)
The correlation between the recoil loop openness and the activation volume has been studied for the SmCo5/α-Fe nanocomposite powder material prepared by mechanical alloying. The α-Fe phase content in the nanocomposite ...
Cutoff Frequencies For Alfven Waves In The Solar Atmosphere
(Physics, 2014-12)
Propagation of linear Alfven waves in the isothermal and non-isothermal solaratmosphere is investigated numerically and analytically. It is shown that thetwo wave variables, the velocity and magnetic field perturbations, ...
Investigating The Global Geospace Response To A Period Of Solar Wind High Speed Streams Using The Lyon-Fedder-Mobarry MHD Simulation
(Physics, 2014-12)
As the solar wind flows past the Earth, it interacts with the Earth's magnetic field and transfers energy and momentum to the geospace environment. During times when the solar cycle is near a minimum, there is a tendency ...
Evidence Of A Positron Bound State On The Surface Of A Topological Insulator
(Physics, 2014-12)
We describe experiments aimed at probing the sticking of positrons to the surfaces of topological insulators performed at university of Texas at Arlington using the Positron Annihilation induced Auger electron Spectrometer. ...
THEORETICAL PREDICTION OF MATERIALS FOR EFFICIENT CONVERSION OF SOLAR ENERGY
(2015-12-07)
Our present work represents a systematic theoretical and computational research to find an affordable material for solar energy application using density functional theory (DFT) and post-DFT such as DFT+U and DFT-HSE06. ...
Bimetallic-waveguide coupled sensors for tunable plasmonic devices
(2015-12-01)
Surface plasmon resonance (SPR) has been a widely used optical technique for the real time and label free sensing applications in biomedicine, homeland security, food safety, environmental monitoring, etc. Surface plasmons ...
THE SEARCH FOR EXOMOON RADIO EMISSIONS
(2015-12-07)
The field of exoplanet detection has seen many new developments since the discovery of the first exoplanet. Observational surveys by the NASA Kepler Mission and several other instrument have led to the confirmation of over ...
A Density Functional Theory Guide To High Quality Modification Of Mixed Metal Oxides Used For Photocatalytic Water Splitting
(Physics, 2015)
Phase stability and charge transport of pristine and transition metal alloyed bismuth titanate (Bi2Ti2O7, a.k.a. BTO), a photocatalytic water splitter, has been studied using the generalized gradient approximated density ...
Biological Damage Of UV Radiation In Environments Of F-type Stars
(Physics, 2014-07-14)
I investigate the general astrobiological significance of F-type main-sequence stars with special consideration to stellar evolutionary aspects due to nuclear evolution. DNA is taken as a proxy for carbon-based macromolecules ...
