Citation analysis Nonextensive statistical mechanics Web of science Tsallis q-exponential distribution
2010/7/5
In this paper we studied the research activity of Brazilian Institutions for all sciences and also their performance in the area of physics between 1945 and December 2008. All the data come from the W...
Physicochemical Characterization of Orally-Active Meglumine Antimoniate/Beta-Cyclodextrin Nanoassemblies: Non-Inclusion Interactions and Sustained Drug Release Properties
cyclodextrin antimony meglumine antimoniate sustained release nanobiotechnology
2010/7/5
b-cyclodextrin (b-CD) is widely used as a component of pharmaceutical formulations, classically to improve the solubility and oral bioavailability of poorly water-soluble drugs through formation of dr...
Surface Characterization of Titanium Based Dental Implants
Titanium implants Dental implants Surface morphology
2010/9/29
The study of dental implant surfaces is relevant in order to better understand the interaction of the titanium
surface and the surrounding tissues. Clinical success is achieved not only because of im...
Characterization of the Main Frequency Shifts for the Brazilian 133Cs Atomic Beam Frequency Standard
the Main Frequency Shifts the Brazilian 133Cs Atomic Beam Frequency Standard
2010/10/15
In order to evaluate an atomic clock, it is important to determine the main frequency shifts caused by external fields, device imperfections, etc. Scanning the frequency of the main oscillator, the Ra...
Synthesis and Characterization of Co-Pb/SBA-15 Mesoporous Catalysts
Mesoporous materials SBA-15 Lead Cobalt Catalyst
2010/4/12
Pure SBA-15 and Co and/or Pb incorporated SBA-15 have been prepared by direct synthesis. The synthesized samples were characterized by powder X-ray diffraction and N2 adsorption isotherms. It is obser...

Experimental Characterization of a Low-Current Cutting Torch
Experimental Characterization a Low-Current Cutting Torch
2010/10/26
An experimental characterization of a low-current (30-40 A) cutting torch is presented. To avoid contamination of the plasma arc by removed anode material, a rotating steel cylinder was used as the an...
Epilayers of Sn1¡xEuxTe (0 < x < 0:03) were grown by molecular beam epitaxy on freshly cleaved
BaF2(111) substrates and their structural, electrical and optical properties were investigated. Th...
Characterization of PbTe p-n+ Junction Grown by Molecular Beam Epitaxy
PbTe p-n+ Junction Molecular Beam Epitaxy
2010/10/22
In this work we investigate the electrical properties of PbTe p ¡ n+ junction. Mesa diodes were fabricated from p ¡ n+ PbTe layers grown on (111) BaF2 substrates by molecular beam epitaxy....
