DC and AC Conductivity of Carbon Nanotubes–Polyepoxy Composites
The dc and ac conductivities of carbon nanotubes-polyepoxy composites have been investigated from 20 to 110 °C in the frequency range 10-10 Hz as a function of the conductive weight fraction p ranging from 0.04 to 2.5 wt %. The frequency dependence of the measured conductivity obeys the universal dynamic response (UDR): a dc plateau followed, above a critical frequency ωc, by the ω power law wi...
متن کاملa comparative move analysis of the introduction sections of ma theses by iranian and native post-graduate students
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
15 صفحه اولDipole-quadrupole degeneracy in kinematic dynamo models with homogeneous conductivity
We discuss and prove dipole-quadrupole degeneracy in kinematic dynamos with homogeneous conductivity and certain very natural symmetry properties. In the case of 2-dynamos, symmetric and antisymmetric modes have the same conditions of excitation and the same real growth rates. For non-vanishing velocity field, i. e. 2!-dynamos (including a possible poloidal flow), symmetric and antisymmetric mo...

متن کاملHopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
