CuMn2O4 nanostructures: Facial synthesis, structural,magnetical, electrical characterization and activation energy calculation

The work is the report about stearic acid sol-gel synthesis method, magnetically, electricalcharacterization and activation energy of copper manganese oxide nanostructures. The CuMn2O4 nanostructures are synthesized at a temperature of 600°C using the sol-gel method. The structural analysis using X-ray diffraction (XRD) and Scherrer equation show that the crystallite size of CuMn2O4 is ab...

Energy Optimization And Calculation Of Dose Absorption Enhancement Factor In Photon Activation Therapy

Introduction: Secondary radiation such as photoelectrons, Auger electrons and characteristic radiations cause a local boost in dose for a tumor when irradiated with an external X-ray beam after being loaded with elements capable of activating the tumor, e.g.; I and Gd. Materials and Methods:  In this investigation, the MCNPX code was used for simulation and calculation of dose enhancement facto...

effective moisture diffusivity, activation energy and energy consumption in thin-layer drying of jujube (zizyphus jujube mill)

jujube (zizyphus jujube mill), a valuable medicinal plant, is consumed either as fresh fruit or dried product in iran. drying jujube guarantees a longer shelf time while preserving its quality to be used in medical and pharmaceutical industries. in this research paper, the influence of several drying conditions on the effective moisture diffusivity, activation energy, energy consumption and req...

Non-equilibrium viscosity and activation energy

This article considers the break in viscosity curves that appears in the glass transition region. It demonstrates that the only possibility to interpret properly the break within the frameworks of the activation energy theory is to assume that at least several independent processes are taking place. Single process cannot explain the break. This assumption was already developed in details in the...
