Propagation And Generation Of Waves In Solar Atmosphere
(Physics, 2010-03-03)
The fact that the temperature increases with height in the solar atmosphere has been known for many years. To maintain this temperature increase, sources of heating must be present in the atmosphere. One of the most ...
Search For Standard Model Higgs In Two Photon Final State At Atlas
(Physics, 2010-11-01)
The Standard Model of particle physics describes very precisely the nuclear strong and weak forces and the eletromagnetic interaction, by the exchange of vector bosons. It also describes all matter as composed of quarks ...
The Role Of The Y-component Of The Interplanetary Magnetic Field In Transpolar Saturation And Ring Current Response As Found In Data And Simulation
(Physics, 2010-07-19)
Energy is transferred into the magnetosphere of Earth through merging of magnetic fields (Dungey cycle and lobe cell convection) and through momentum transfer across the magnetopause (viscous interactions). These processes ...
Synthesis Of Cdte And Pbs Semiconductor Quantum Dots And Their Biological And Photochemical Applications
(Physics, 2010-07-19)
Semiconductor quantum dots are inorganic nanoparticles with unique photophysical properties. In particular, water soluble quantum dots which have been synthesized by colloidal chemistry in aqueous environment are highly ...
Tracking Stellar Activity Enhancements Due To A Close-in Giant Planet In The HD 179949 System
(Physics, 2010-07-19)
We monitored CaII H and K lines (3933Å and 3968Å) of the HD 179949 system to study Planet Induced Emission (PIE) as an effect of star-planet interaction. We obtained high resolution spectra (R > 50,000) with high signal-to-noise ...
Fabrication of bulk nanocomposite magnets via severe plastic deformation and warm compaction,
(American Institute of Physics, 2010-03-10)
We demonstrate that a SmCo/FeCo based hard/soft nanocomposite material can be fabricated by distributing the soft magnetic α-Fe phase particles homogeneously in a hard magnetic SmCo phase through severe plastic deformation. ...
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 ...
