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). ...
Flocculation and viscoelastic behavior of industrial papermaking suspensions
(
Springer New York LLC
, 2016 , Article)
The effects of the surface charge type and density C496, C492 and A130LMW polyacrylamides (PAMs) on the rheological behavior of real industrial papermaking suspensions were quantitatively related to the degree of flocculation ...
Trap States and Their Dynamics in Organometal Halide Perovskite Nanoparticles and Bulk Crystals
(
American Chemical Society
, 2016 , Article)
Organometal halide perovskites have attracted tremendous attention for optoelectronic applications. Charge carrier trapping is one of the dominant processes often deteriorating the performance of devices. Here, we investigate ...
Effect of pH on dissolution of iron sulfide scales using THPS
(
Society of Petroleum Engineers (SPE)
, 2019 , Conference Paper)
Iron Sulfides scale has been a critical problem for oil and gas wells for several decades. One of the best candidates to remove these scales is tetrakis(hydroxymethyl)phosphonium sulfate (THPS). Most studies on the dissolution ...
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 ...
Investigation of the hydrogen adsorbed density inside the pores of MOF-5 from path integral grand canonical Monte Carlo at supercritical and subcritical temperature
(
Science in China Press
, 2016 , Article)
We examine the high density limit of the adsorption isotherms of hydrogen on MOF-5. The isotherms are calculated using quantum GCMC simulations over the pressure range: 0–150 atm (1 atm = 1.01325 × 105 Pa) in the subcritical ...
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 ...
Synthesis of Metallocene Catalyzed Ethylene 1,7-Octadiene Copolymer: Effect of Copolymerization on Polymer Properties
(
Polymer Society of Korea
, 2018 , Article)
In this article, metallocene catalyzed polyethylene homopolymer and ethylene 1,7-octadiene copolymers were synthesized and the produced polymers were characterized. The results show that these polymers were high density ...
Enhanced Size Selection in Two-Photon Excitation for CsPbBr3 Perovskite Nanocrystals
(
American Chemical Society
, 2017 , Article)
Cesium lead bromide (CsPbBr3) perovskite nanocrystals (NCs), with large two-photon absorption (TPA) cross-section and bright photoluminescence (PL), have been demonstrated as stable two-photon-pumped lasing medium. With ...
