The detection of the theoretically expected dark matter is central to particle physics and cosmology. Current fashionable supersymmetric models provide a natural dark matter candidate which is the lightest supersymmetric particle (LSP). The theoretically obtained event rates are usually very low or even undetectable. So the experimentalists would like to exploit special signatures like the dire...

This study investigates the non-isothermal reduction of iron ore fines with two different carbon-bearing materials using thermogravimetric technique. The fines/carbon composites were heated from room temperature up to 1100 °C heating rates (5, 10, 15, and 20 °C/min) under an argon atmosphere. effect carbon sources on rate was intensively investigated. Reflected light scanning electron microscop...

Abstract Non-isothermal reaction mechanism and kinetic analysis for the synthesis of monoclinic lithium zirconate (m-Li 2 ZrO 3 ) were investigated by processing TG-DTA, along with XRD, DLS, HRTEM. For this purpose, solid-state Li CO was carried out TG-DTA at different heating rates (10, 20, 30 °C/min) from room temperature to 1100 °C. The thermal data used calculate parameters two types isocon...

Abstract In this paper, films based on sustainable polymers with variable charge have been investigated by non-isothermal thermogravimetry in order to predict their lifetime, which is a key parameter for potential use numerous technological and biomedical applications. Specifically, chitosan has selected as positively charged biopolymer, while alginate chosen negatively biopolymer. Among non-io...

We study non-isothermal nucleation and growth phase transformations, which are described by a generalized Avrami model for the phase transition coupled with an energy balance to account for recalescence effects. The main novelty of our work is the identification of temperature dependent nucleation rates. We prove that such rates can be uniquely identified from measurements in a subdomain and ap...

water and energy are key commodities utilized in the process industries.water minimization and energy minimization have been studied separately. in this paper, a new systematic design methodology has been developed for the simultaneous management of energy and water systems that also feature maximum re-use of water. in addition to allowing re-use of water, issues about heat losses inside unit o...

To disclose the formation pathway at extreme conditions combustion synthesis NiO-WO3-Mg-C and NiWO4-Mg-C systems for optimization procedure, process was modeled under programmed linear heating by thermal analysis methods. The reduction kinetics tungsten nickel ...

The formulation of a two surface/bubble thermo-mechanical constitutive model consistent with the principles thermodynamics is presented. This allows plastic deformations inside outer yield surface, resulting in smooth stress–strain prediction and progressive cyclic deformations. achieved by translation inner surface (also known as bubble surface) stress state soil, using kinematic rule. equatio...

Direct reduction of iron ore with H2 has become an alternative technology for production that reduces pollutant emissions. The kinetics fines in atmosphere under isothermal and non-isothermal conditions were studied by thermogravimetric analysis. X-ray diffraction scanning electron microscopy used to measure the mineral composition analyse morphology reduced fines, respectively. In experiment, ...
