The ferrochrome alloy is produced by electric arc melting of the mineral chromite (FeCr2O4). It is largely used for the production of stainless steels. Increasing the amount of chromium content in the steel allows for increased corrosion and oxidation resistance. Other alloying elements, such as nickel (Ni) or molybdenum (Mo), aid in making the steel more passive and increasing its stainless pr...
In this study, the effect of copper chromite (CuO.Cr2O3) nanoparticles and multi-walled carbon nanotubes (MWCNTs) as nanocatalysts on the thermal decomposition behavior of ammonium perchlorate (AP) has been investigated using Differential Scanning Calorimetry (DSC). At first, copper chromite (CuO.Cr2O3) nanoparticles were prepared by inverse co-precipitation method. In this method, cupric nitra...
the number of vegetable processing plants has been increased during recent years in iran as many other countries. on the other hand, fresh vegetable products are susceptible to microbial contamination after harvest, processing, handling, packing and distribution. the aim of this study was to determine and evaluate the level of microbial load of vegetables during different cleaning steps in a fr...
Fractal geometry has developed rapidly, and is widely used in various disciplines. However, only a few fractal dimension methods techniques have been applied to the processing of gravity data, especially detection geological edges interfaces. In this paper, definition, properties characteristics dimensions are improve edge anomalies, theoretical model established. At same time, new method surfa...
In this study, the relationships between liberation degree and kinetic breakage parameters of a chromite ore obtained from Burdur (Türkiye) were examined under laboratory conditions. Firstly, degrees for particles determined by particle counting method in metal microscope 4 different size groups. Secondly, parameter which was dry ground with ball mill using standard test methods. Additionally, ...
Heterogeneous selective hydrogenation of ethylene carbonate (EC), a key step in indirect conversion of CO2, was realized over a copper chromite nanocatalyst prepared via a hydrothermal method followed by calcination. The selectivities towards methanol (60%) and ethylene glycol (93%) were higher than those achieved over other usual hydrogenation catalysts.
