Modeling of dual-metal Schottky contacts based silicon micro and nano wire solar cells
( Elsevier B.V. , 2014 , Article)We study solar cell properties of single silicon wires connected at their ends to two dissimilar metals of different work functions. Effects of wire dimensions, the work functions of the metals, and minority carrier lifetimes ... -
Hydrogen bond coupling in sodium dihydrogen triacetate
( Springer Verlag , 2014 , Article)The coupling of hydrogen bonds is central to structures and functions of biological systems. Hydrogen bond coupling in sodium dihydrogen triacetate (SDHTA) is investigated as a model for the hydrogen bonded systems of the ... -
Simulation study of Schottky contact based single Si wire solar cell
( IEEE , 2014 , Conference Paper)We model single silicon nanowire (SiNW) solar cells with dissimilar work function metal contacts. Both short circuit current (ISC) and open circuit voltage (VOC) have been investigated. Effects of nanowire dimension, ... -
Photoconductive response of strained silicon nanowires: A Monte Carlo study
( AIP Publishing LLC. , 2014 , Article)Using Ensemble Monte Carlo simulations, the photocurrent in a 500 nm long strained [110] silicon nanowire with diameter of 3.1 nm is investigated. It was observed that a phototransistor based on this nanowire can have ... -
Rheology of a viscoelastic zwitterionic surfactant used in acid stimulation: Effects of surfactant and electrolyte concentration
( Elsevier , 2014 , Article)Acid diversion systems play an important role in increasing the efficiency of the acid stimulation process. Viscoelastic surfactant (VES) based diverting systems have many advantages that make them preferred for well acid ... -
Optimization of selection of chain amine scrubbers for CO2 capture
( Springer Verlag , 2014 , Article)In order to optimize the selection of a suitable amine molecule for CO2 scrubbers, a series of ab initio calculations were performed at the B3LYP/6-31+G(d,p) level of theory. Diethylenetriamine was used as a simple chain ... -
Effect of the degree of template removal from mesoporous silicate materials on their adsorption of heavy oil from aqueous solution
( Springer VerlagHigher Education Press , 2014 , Article)The key aim of this study is to evaluate the adsorption of heavy oil from aqueous solutions with different oil contents over mesoporous silicate materials having different surfactant template contents. The mesoporous ... -
Adsorption of an anionic surfactant at air-liquid and different solid-liquid interfaces from solutions containing high counter-ion concentration
( Springer Verlag , 2015 , Article)The self-assembly (adsorption) of the anionic surfactant, sodium dodecylbenzenesulphonate (SDBS), at air-liquid and different (octadecanethiol, β-mercaptoethanol, α-lipoic acid) solid-liquid interfaces from aqueous solutions ... -
Demulsification of stable emulsions from produced water using a phase separator with inclined parallel arc coalescing plates
( Elsevier , 2015 , Article)A novel and highly efficient oil-water separator equipped with a series of inclined multiple arc coalescence plates is developed and optimized for the removal of stable oil emulsions from produced water. The synthetic high ... -
Ab initio molecular dynamics study of the interlayer and micropore structure of aqueous montmorillonite clays
( Elsevier Ltd , 2015 , Article)Ab initio molecular dynamics simulations have been performed to gain an understanding of the interfacial microscopic structure and reactivity of fully hydrated clay edges. The models studied include both micropore and ... -
Thermochemical treatment of fly ash for synthesis of mesoporous activated carbon
( Springer Netherlands , 2015 , Article)A mesoporous activated carbon is produced from oil fly ash (OFA) using chemical and thermal treatments at different activation conditions. The ash samples were refluxed with a range of compositions of sulfuric, nitric, and ... -
DSC investigation of the gelation kinetics of emulsified PAM/PEI system: Influence of surfactants and retarders
( Springer Netherlands , 2015 , Article)Water production in the oilfields has a negative impact on the production and economy. It is highly desired to shut off water paths without affecting the hydrocarbon zones. Polymer gels are frequently used for water control ... -
Synthesis of minimal-size ZnO nanoparticles through sol-gel method: Taguchi design optimisation
( Elsevier BV , 2015 , Article)Zinc oxide (ZnO) has excellent potential to be used in water and wastewater treatment, either as a photocatalyst or in membrane incorporation. In this work, the synthesis of smaller ZnO NPs through a sol-gel approach was ... -
Optimization of nickel oxide nanoparticle synthesis through the sol-gel method using Box-Behnken design
( Elsevier BV , 2015 , Article)In this study, nickel oxide nanoparticles were prepared using the sol-gel method. The process parameters were optimized to produce smaller size of nanoparticles such as molar ratio, solution pH and calcination temperatures. ...
