Cleaning of ceramic membranes for produced water filtration
(
Elsevier
, 2018 , Article)
© 2018 Elsevier B.V. The application of ceramic microfiltration membranes to the tertiary treatment of produced water from an Arabian Gulf oilfield has been studied using a dedicated pilot plant. Studies were based on a ...
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 ...
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 ...
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 ...
High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
(
American Chemical Society
, 2016 , Article)
We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ...
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 ...
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. ...
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 ...
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 ...
