Electrical Properties Polyaniline X-rays
2010/10/15
Recent development and studies of physical and chemical properties of the conducting polymers have been calling the interest of many scientists. Among this group of materials, the polyaniline (PANI) d...
Great Geomagnetic Storms in the Rise and Maximum of Solar Cycle 23
Great Geomagnetic Storms the Rise and Maximum Solar Cycle 23
2010/10/26
Geomagnetic storms are intervals of time when a sufficiently intense and long-lasting interplanetary convection electric field leads, through a substantial injection of energy into the magnetosphere-i...
Electron Cyclotron Emission Simulation from TCABR Plasmas
Electron Cyclotron Emission TCABR Plasmas
2010/10/27
Electron cyclotron emission due to electrons described by a particular distribution function has been studied. The latter presents an extended tail generated by the interaction of the Lower Hybrid wav...
Collisional Electron Detachment of Atomic Anions by Noble Gases: Universal Behavior at Intermediate Velocities
Collisional Electron Detachment Atomic Anions Noble Gases Intermediate Velocities
2010/10/25
Anions with atomic number lower than 18 had their total electron detachment cross sections measured in the 0.3-1.5 a:u: velocity range (40 keV-1.4 MeV) for He, Ne, and Ar targets with a experimental m...
Heteroisotopic molecular behavior. The Valence-Bond Theory of the Positronium Hydride
Heteroisotopic molecular behavior The Valence-Bond Theory the Positronium Hydride
2010/10/26
We develop an adiabatic valence-bond theory of the positronium hydride, HPs, as a heteroisotopic diatomic molecule. Typical heteronuclear ionic behaviour comes out at bonding distances, yielded just b...
Unified Study of Electrical Resistivity of Simple and Non-Simple Liquid Metals
Electrical Resistivity Simple and Non-Simple Liquid Metals
2010/10/26
A model potential depending on an effective core radius but otherwise parameter free is used for the comparative study of electrical resistivity of simple and non-simple liquid metals. In the present ...
Study of the Electron-Positron Annihilation Coincidence Peak Two-Dimensional Profile
the Electron-Positron Annihilation Coincidence Peak Two-Dimensional Profile aluminum Ge detectors
2010/10/26
Positron annihilation radiation profile in aluminum was observed with a pair of Ge detectors in coincidence. 22Na was used as a source of positron and the two-dimensional gamma energy spectrum was fit...
Electronic Structure of the n-Type Doped AgInO2 and CuAlO2 Delafossites: Similarities and Differences
Electronic Structure the n-Type Doped AgInO2 and CuAlO2 Delafossites Similarities and Differences
2010/10/21
We performed the first-principles band-structure calculations for a pure and a Cd-doped AgInO2 delafossite compound. The results are carefully analyzed and compared with the results obtained for a pur...
