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). ...
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 ...
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 ...
Rheological and thermal properties of novel surfactant-polymer systems for EOR applications
(
Wiley-Liss Inc.
, 2016 , Article)
In this work, two surfactant-polymer (SP) systems were evaluated for enhanced oil recovery applications. The first SP system contained partially hydrolyzed polyacrylamide and alkyl polyethylene glycol ether-based non-ionic ...
Enhanced photovoltaic performance with co-sensitization of a ruthenium(ii) sensitizer and an organic dye in dye-sensitized solar cells
(
Royal Society of Chemistry
, 2016 , Article)
Co-sensitization is demonstrated to be an effective technique to enhance the efficiency of dye-sensitized solar cells, where an efficiency of 9.23% is achieved by mixing N3 and RK-1 dyes. The assembled solar cells are ...
Enhanced photovoltaic performance of dye-sensitized solar cells using TiO2-graphene microplatelets hybrid photoanode
(
IEEE Electron Devices Society
, 2016 , Article)
Hybrid photoanodes for dye-sensitized solar cells (DSSCs) were prepared by simple addition of graphene (GR) microplatelets to TiO 2 nanoparticulate paste. Transmission electron microscopy was used to confirm the presence ...
Application of various water soluble polymers in gas hydrate inhibition
(
Elsevier Ltd
, 2016 , Article Review)
Formation of hydrates in gas transmission lines due to high pressures and low temperatures is a serious problem in the oil and gas industry with potential hazards and/or economic losses. Kinetic hydrate inhibitors are water ...
Review on recent advances in polythiophene based photovoltaic devices
(
Elsevier Ltd
, 2016 , Article Review)
Discovery of conducting polymer introduced us to the total polymeric solar cells (PSC). During the last decade, power conversion efficiency (PCE) of these solar cells has increased from 1% to 11.5% (with the bulk heterojunction ...
