Effect of electrolytes on electrokinetics and flocculation behavior of bentonite-polyacrylamide dispersions
(
Elsevier Ltd
, 2018 , Article)
© 2018 Elsevier B.V. In this study, the influence of electrolytes on bentonite dispersions flocculated with different polyacrylamides varying in charge type, density and molecular weights has been investigated. The presence ...
Review on Surfactant Flooding: Phase Behavior, Retention, IFT, and Field Applications
(
American Chemical Society
, 2017 , Article Review)
Surfactant flooding is an important technique used in enhanced oil recovery to reduce the amount of oil in pore space of matrix rock. Surfactants are injected to mobilize residual oil by lowering the interfacial tension ...
Novel fluorinated surfactants for enhanced oil recovery in carbonate reservoirs
(
Wiley-Liss Inc.
, 2016 , Article)
Novel surfactant‐polymer (SP) formulations containing fluorinated amphoteric surfactant (surfactant‐A) and fluorinated anionic surfactant (surfactant‐B) with partially hydrolyzed polyacrylamide (HPAM) were evaluated for ...
Enhancing Power Conversion Efficiency of Dye-Sensitized Solar Cell Using TiO2-MWCNT Composite Photoanodes
(
IEEE Electron Devices Society
, 2016 , Article)
The aim of this work is to improve the power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs) using composite films consisting of titanium oxide (TiO2) nanoparticles and multiwalled carbon nanotubes (MWCNTs). ...
An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
(
Taylor and Francis Inc.
, 2019 , Article)
Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ...
Synthesis, Characterization and Surface Properties of Amidosulfobetaine Surfactants Bearing Odd-Number Hydrophobic Tail
(
Springer Verlag
, 2016 , Article)
Three amidosulfobetaine surfactants were synthesized namely: 3‐(N‐pentadecanamidopropyl‐N,N‐dimethyl ammonium) propanesulfonate (2a); 3‐(N‐heptadecanamidopropyl‐N,N‐dimethyl ammonium) propanesulfonate (2b), and ...
Controlled growth of Cu2O thin films by electrodeposition approach
(
Elsevier Ltd
, 2017 , Article)
Thin films of Cu2O comprised of wavelike surface characteristic of compact nanoparticles were synthesized using a facile and cost-effective electrodeposition approach. The distinct surface morphologies with well-aligned ...
Adsorption kinetics and modeling of H2S by treated waste oil fly ash
(
Taylor and Francis Inc.
, 2019 , Article)
Waste oil fly ash (OFA) collected from disposal of power generation plants was treated by physicochemical activation technique to improve the surface properties of OFA. This synthesized material was further used for potential ...
An Experimental and Kinetic Study of the Sorption of Carbon Dioxide onto Amine-Treated Oil Fly Ash
(
Hindawi Publishing Corporation
, 2016 , Article)
A new CO2 adsorbent is produced from waste oil fly ash (OFA). Ammonium hydroxide solution is used to convert OFA to activated carbon. Then, the product is used for the adsorption of CO2 from a nitrogen/carbon dioxide ...
Improvement in Photovoltaic Performance of Dye Sensitized Solar Cell Using Activated Carbon-TiO2 Composites-Based Photoanode
(
IEEE Electron Devices Society
, 2016 , Article)
In this study, the activated carbon (AC) is synthesized from the oil fly ash (FA). Noncarbonaceous impurities were eliminated by acidic treatment of oil FA. Brunauer-Emmett-Teller and scanning electron microscopy ...
