The ionic conductivity of LiSO3CF3 complexed with wax-like solids of the general form H-(CH2)32 (CH2CH2O)10-H were investigated. The conductivity of the waxes studied in this work should be dependent on the shape of the domains. Conductivity measurements were made perpendicular, σ⊥, and parallel, σ, to the direction of molecular orientation. Depending on the size of the conducting domains, an...

We analyse the consequences of Quincke rotation on the conductivity of a suspension. Quincke rotation refers to the spontaneous rotation of insulating particles dispersed in a slightly conducting liquid and subject to a high DC electric field: above a critical field, each particle rotates continuously around itself with an axis pointing in any direction perpendicular to the DC field. When the s...

–Expressions are obtained for the thermal conductivity of some ABO3 type displacive ferroelectrics in paraelectric phase, using Kubo formalism and double time thermal Green’s function technique. The total thermal conductivity obtained for these perovskites which is sum of two terms contributed by optical and acoustical phonons, is in agreement with the experimental results of Steigmeier. The va...

The total electric resistance R is theoretically linearly increasing function of the conductive wire length L because the electric conductivity K or electric resistivity r is independent on L. It was found out that dependence of electric resistance R on L is highly nonlinear for yarns containing the conductive metal fibers. The main aim of this paper is creation of the simple mechanistic model ...

Knowledge on rheological properties of sludge is important for the design of pumping and transport facilities and as a tool in process control during treatment. Concentrated activated sludge is known to behave as a non-Newtonian material. The contribution to nonNewtonian behaviour is believed to originate from the colloidal properties of solids more than from the molecular properties of the sus...
