A Direct Method

The room temperature transmission spectra of Agx TaS2 and Agx TiS2 have been measured in the energy range from about 1.3 to 2.8 eV for various values of x. A rigid band model, where charge transfer from the silver cation to the lowest d conduction band of the host macro-anion occurs, can explain the changes in the spectra. These changes in the transmission spectra provide a direct method for monitoring staging and the intercalation rate of the silver ions.

Calculations have been made using the Fletcher and Butcher method in a three conduction band model to fit a wide range of experimental transport data for n-type samples of GaSb: viz. Hall coefficient and electrical conductivity as a function of temperature and as a function of pressure at room temperature, magnetoresistance as a function of magnetic field at different temperatures, and Nernst–Ettingshausen coefficients as a function of magnetic field. Various energy gap parameters and scattering coefficients have been taken as adjustable and values determined for these which give good fits to all of the experimental data. Values of mobility for each of the Γ, L, and X bands have then been calculated as a function of temperature.

A Direct Method

AbstractWe report hereby the first method of direct treatment of a wet soil containing toxic polychloroderivatives. Using a system with metallic Ca and 5% Rh fixed on charcoal in methanol, soil samples artificially polluted with fly ash containing polychloro-dibenzodioxins (PCDDs), polychloro-dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (co-PCBs), and having 69.2% to 84.6% moisture content, were successfully treated and decontaminated. This treatment afforded excellent hydrodechlorination yields for the 29 most toxic congeners of PCDDs, PCDFs and PCBs (98.3% degradation yield based on toxic equivalent quotient — or TEQ) after a 24 h treatment, at room temperature.

The thermoelectric powers of the intermetallic compounds V3Ge, V3Si, V3Ga, and V3Sn have been measured from their superconducting transition temperatures to room temperature. It is found that the thermoelectric coefficients are all positive and about 10 μv/° K at room temperature. The coefficients for V3Si, V3Ga, and V3Sn are monotonically increasing functions of the temperature, whereas for V3Ge there is a pronounced maximum at about 60° K. The results are discussed in terms of a two-band model consisting of a conduction band and a d-band.
