Nitro aromatic compounds such as, 2-nitrophenol and 4-nitrophenol are identified lethal to human due to their constructive role in causing the problems such as, vertigo, headache, fainting and mental disturbance. A strong remedy is desired to treat aqueous environment for these toxic aromatic species. In this pursuance, gum arabic (GA) [...]

The aim of this work is to reduce the impact on the environment of a basic textile dye (azucryl red) using a semiconductor TiO2 and Fe doped TiO2 powders calcined at 600 °C as catalysts. The refinements based on the Rietveld method of x-ray diffraction patterns indicate the formation of [...]

Pure and Ni-doped WO 3 nanoparticles were synthesized by hydraulic acid-assisted precipitation, followed by thermal calcinations. The procedure utilized sodium tungstate (Na 2 WO 4 ) doped with different amounts of Ni ions. The samples were characterized by X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), and magnetic measurements. The XRD [...]

ANN is a very well-known approach used for classification based on supervised machine learning. This approach faces some issues, notably the local minima problem, which leads to diminished accuracy in the results. To solve the problem of local minima, a new algorithm called RPSOGAC has been proposed. The proposed algorithm [...]

Fabrication of a suitable photocatalyst which can efficiently propagate catalytic properties in visible spectrum has always been a challenge. Novel nanocomposites LaDySn 2 O 7 /SnSe as well as the individual components of the composite were fabricated via the hydrothermal route. The structural, textural as well as optical characteristics of [...]

In recent years, extensive researches were devoted to iron oxide nanoparticles (IONPs), including magnetite (Fe3O4) and maghemite (γ-Fe2O3), due to their low toxicity and cost, in addition to their unique physicochemical and magnetic properties. In this review, we present a brief introduction on IONPs in terms of classification and properties. [...]

In this study, pyrolysis of waste polystyrene was investigated in the presence of a mixed metal oxide (Nix=0.5Cu1-xO) under inert conditions in a pyrolysis chamber. The pyrolysis products were collected and analyzed by gas chromatography/mass spectrometry. Kinetic parameters were determined from thermogravimetric data, and the activation energy and pre-exponential factor [...]

Biofuel production via microalgae is a promising and sustainable alternative to replace the typical fossil fuel that is the main contributor to the global warming. However, for a cost-effective biofuel production, further advanced research is still needed for large-scale operation. This article is a tutorial review on conversion processes of [...]

This paper presents a novel technique to mitigate fouling and reduce effects of concentration polarization in reverse osmosis (RO) membranes. The technique will be referred to as the temporary step-wise cyclic operation. The method is based on superimposing a cyclic square pressure pulses on the operating pressure for a short [...]

Several studies have investigated indirect evaporative cooling (IEC) systems with regeneration, both experimentally and mathematically. The mathematical models developed to analyze the IEC are commonly based on ε-NTU method. However, this study develops the mathematical model from first principles, mass, momentum and energy balances for higher accuracy and deeper insights [...]
