Entropy generation for the natural convection phenomena is studied for different geometrical cavities that have identical boundary conditions and unit area. The key characteristic parameter in this study was the Grashof number. The effect of Grashof number on Nusselt number and entropy generation has been studied using finite element method. [...]

Water purification has become a worldwide problem, in particular in industrialized countries, where wastewater usually contains organic pollutants, such as dyes from the textile industry, leather tanning industry, paper production, food technology, agricultural and pharmaceutical industries. The development of an effective treatment for these effluents is the subject of considerable [...]

Previous studies on company scores conducted at firm-level, generally concluded that there exists a positive relation between company scores and stock returns. Motivated by these studies, this study examines the relationship between company scores (Corporate Governance Score, Economic Score, Environmental Score, and Social Score) and stock returns, both at portfolio-level [...]

In the present work, zinc ferrite nanostructured materials were synthesized by a microwave combustion method (MCM) using Okra (Abelmoschus esculentus) as a plant extract and compared with the ones synthesized by a conventional combustion method (CCM). Plant extracts play a dual role of both oxidizing and reducing nature. Microwave assisted [...]

First principles calculations were performed to investigate the influence of vacancy and alkali/alkali earth metals (Li, Na, K and Ca) doping on the dehydrogenation properties of Mg7TiH16. The occupation energy of dopants and dehydrogenation energy of defected Mg7TiH16 were calculated. It was found that dopants prefer to substitute for Mg [...]

The structural, optical and electrical properties of un-doped and (Al,Er) co-doped zinc oxide (ZnO) powders synthesized by hydrothermal method were investigated. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive spectroscopy and magnetic measurements. XRD results reveal that the incorporation of Al and Er in [...]

Bi2Se3 powder has been successfully synthesized via mechanical ball milling of bismuth and selenium as starting materials. X-ray diffraction characterization revealed the formation of the rhombohedral and orthorhombic phases of Bi2Se3 material belonging to systems with space groups R 3 ¯ m and Pbnm, respectively. The advantageous last finding is [...]

Artificial Neural Network (ANN) has played a significant role in many areas because of its ability to solve many complex problems that mathematical methods failed to solve. However, it has some shortcomings that lead it to stop working in some cases or decrease the result accuracy. In this research the [...]

Nanocrystalline Cu50Ni50 alloy powder was prepared by the mechanical alloying process in high-energy planetary ball mill P7 under an argon atmosphere. Structural, microstructural, morphological, and magnetic properties were followed by X-ray diffraction, scanning electron microscopy coupled with EDX analysis, and vibrating sample magnetometry. The mixing of Cu and Ni powders [...]

The sustainable and eco friendly green synthesis report on the use of plant extract alternate to chemicals has been discussed. In this work, opuntia plant extract is used as a natural reagent to synthesize nanoparticles. Herein, we demonstrate two methods namely, conventional and microwave method for the synthesis of nanoparticles [...]
