background and aim: iron overload in patients with thalassemia major is one of the most important complications of this disease and its cardiac complications are the most important causes of death in these patients.mri t2 is the perfect device to assess the amount of iron deposited in the heart of thalassemia patients, but it causes waste of time and also is an expensive diagnostic method. tiss...
the oxidation of ferrous iron (fe2+) in solution using acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. the aim of this investigation was to increase the...
In this paper, we consider a corrosion model of iron based alloy in nuclear waste repository. It consists in a PDE system, similar to the steady-state drift-diffusion system arising in semiconductors modelling. The main difference lies in the boundary conditions since they are Robin boundary conditions and infer an additional coupling between the equations. Using a priori estimates on the solut...
Modified iron phosphate glasses have been prepared with nominal molar compositions [(1−x)·(0.6P2O5– 0.4Fe2O3)]·xRySO4, where x = 0–0.5 in increments of 0.1 and R = Li, Na, K, Mg, Ca, Ba, or Pb and y = 1 or 2. In most cases the vast majority or all of the sulfate volatalizes and quarternary P2O5–Fe2O3–FeO–RyOz glasses or partially crystalline materials are formed. Here we have characterized the ...
Recycling is a logical option for materials that are not suitable for composting. One of these materials is iron mines waste that, according to their compounds, can be used as a substitute part of cement in concrete. For this aim, rheological and mechanical properties and durability of light weight self-compacting concrete (LWSCC) containing Sirjan iron mine waste (SIMW) as partial substitute o...
The PCM based energy storage system is commonly used for storing waste heat and solar heat. Main disadvantage of such system is slow response during charging and discharging. In the present experiment thermal conductivity of wax based storage system is improved by embedding Copper,Aluminium and iron springs. Experiments shows that such systems show superior performance during charging and disch...
Capillary zone electrophoresis was used in the analysis of anions and cations in electroless plating bath samples. Examples described in this application note include the analysis of inorganic and organic anions in nickel-plating baths, cations in nickel-iron-cobalt-plating baths and metal-EDTA complexes in plating bath waste. Sample preparation was minimal, consisting merely of diluting the sa...
Nanoparticles are being intensively investigated because of their unique optical, electrical and catalytic properties which make them a potential material for utilization in the field of medicine electronic and environmental issues. This paper is concerned with the removing a heavy metal, Chromium, from its aqueous solution by Iron oxide nanoparticle filtration. Solutions of varying chromium co...
