In the present work, we provide the information on the variation of electrical conductivity of NaOH, KOH and LiOH(1 to 6N) with temperature (room temperature to 70掳). It is observed that specific conductance increases with temperature and concentration. The rise is predominant at higher ...
As can be seen thermal conductivity did not show any predictive trend with total number of carbons (Fig. 10a). The thermal conductivity measured in the solid-state at room temperature for the PCMs, alkanes, and sugar alcohols fit in an apparent sigmoidal curve as a function of the number ...
At each temperature the complex impedance displays a perfect semi-circular arc that represents the grain-interior conduction. Under the experimental conditions, electrical conductivity exponentially increases with increasing temperature and slightly decreases with increasing pressure; however, the effect of ...
The variations in thermal conductivity are empirically correlated with the present experimental data by the equation K( T) = AT m, where A and m have different values before and after the glass transition temperature. Similarly, heat capacity also increases with temperature and then reaches a ...

Traditionally, metals have a constant thermal conductivity with increasing temperature. The notable exception is the conductivity of iron, which rapidly decreases with increasing temperature until about 1100K when it slowly increases (Powell et al., 1966). Minerals have the general trend of having a...
We conclude that hydrogen enhances the electrical conductivity of pyrope-rich garnet and its effect increases with pressure but decreases with temperature. At a typical pressure and temperature in the upper mantle, the influence of water is substantial. 展开 关键词: Electrical conductivity Pyrope ...
The probe method was used to measure thermal conductivity of beef through a temperature range of 30–120°C. Thermal conductivity of beef increases with temperature up to 70°C followed by a decrease during the denaturation of proteins and subsequent loss of water. The thermal conductivity of bee...
1.56 MHz and 2.3 MHz constant frequencies change of electric conductivity depending on temperature is observed with the least speed (Fig. 3). As it is seen from figure minimum natural logarithm value of electric conductivity at high frequency range is “−17”. It increases up to “−12”...
We investigate the scalability of the temperature- and electric field-dependence of the conductivity of disordered organic semiconductors to ‘universal’ curves by two different but commonly employed methods; by so-called universal scaling and by using
