In this work, the optical properties dependence of Multi-Walled Carbon Nanotubes (MWNT) on concentration was discussed. MWNT samples were prepared in polypyrrole by an electrochemical polymerization of monomers, in the presence of different concentrations of MWNTs, using Sodium Dodecyl-Benzen-Sulfonate (SDBS) as surfactant at room temperature. The nonlinear refractive and nonlinear absorbtion i...
To test the hypothesis that brain oxidative metabolism is significantly increased upon adequate stimulation, we varied the presentation of a visual stimulus to determine the frequency at which the metabolic response would be at maximum. The authors measured regional CMR(O2) in 12 healthy normal volunteers with the ECAT EXACT HR+ (CTI/Siemens, Knoxville, TN, U.S.A.) three-dimensional whole-body ...
In 1993 LEP performed a scan at three energy points around the Z 0 mass, with the primary aim of substantially improving the errors on M Z and ? z. The results of the preliminary lineshape analyses of the 4 LEP experiments are presented here, together with the combined LEP averages. The Z 0 mass and width are determined as M Z = 91:1899 0:0017 exp 0:004 lep Gev and ? z = 2:4971 0:0027 exp 0:002...
