One of the characteristics of solid organic compounds and especially organic explosives is thermal behavior and kinetic of thermal decomposition. The activation energy, Arrhenius constant and model of solid state reaction as kinetic triplet can be obtained by study thermal decomposition kinetic in a solid state reaction. In the present work, the non-isothermal differential thermal analysis (DTA...

Thermal conductivity of superconducting MgB 2 was studied in both the superconducting and the normal state region. The latter is almost equally determined by the electronic-and the lattice contribution to the total thermal conductivity. In the superconducting state, however, the lattice contribution is larger. The electronic thermal conductivity below T c was derived from the experimental data ...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simultaneously using transient plane source technique. The temperature dependence of thermal transport properties is studied in the temperature range 83-303 K. Different relations for the estimation of thermal conductivity are also tested. T...

Electricity has been considered as a pivotal product for sustainable development. As Iran has access to the high level of fossil fuel resources, the major proportion of Iranchr('39')s power generation belongs to thermal power plants. In this regard, the issue that all governments have faced is financing the initial capital costs of these projects, which plays a crucial role in providing a conti...

Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...
