Nickel and cadmium usually enter the environment and water resources through wastewater, released by various industries, and may have adverse effects. The current study employs α–Fe2O3 nanoparticles of 20-40 nm in order to remove nickel and cadmium from the wastewater of Saba Battery Company. Also, it investigates the influence of effective parameters on adsorption process, including pH, contac...

Functionalized polymeric microspheres based on a modifed polyether ether keetone (PEEK-WC) using immersion precipitation techniques were successfully prepared by doping initial polymeric solutions with DEHPA. The viscosity of the doping solution was measured for determining the optimal value for obtaining reproducible capsules. The modifed microspheres were characterize...

In this study, slurry polymerization kinetics of ethylene with TiCl4/Mg(OEt)2/AlR3 Ziegler-Natta catalysts in various conditions using the model of sum square error (SSE) (method I) and model of least square error (LSE) (Method II) was investigated. For this purpose the molecular weight distributions of the samples were deconvoluted to the minimum number of Flor...

this paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say l and d) into a monochiral state (in which only one enantiomer, say l, is present). transitions of this kind have been recently experimentally observed. a plausible approach to this phenomenon is a model put forward by frank, based on simple laws of chem...

Background: Obesity is an escalating public health problem. It is a major risk factor for atherosclerosis, hypertension, and type 2 diabetes. Since circulating levels of the adipocytokins are associated with obesity and dyslipidemia, we investigated the relationship of plasma adipocytokine concentrations with VLDL apolipoprotein B (apoB)-100 kinetics in men. Methods: Plasma adiponectin, lepti...

Abstract Commonly applied 3D CFD models lack suitable combustion description of fuels with complex composition, such as encountered in wastewater sludge specific applications. This significantly influences their prediction capability, particular when used small, confined volumes. To tackle this challenge, it is necessary to introduce detailed chemical kinetic for specifically tailored fuel surr...
