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 ...
Synthesis and characterization of Cu/ZnO catalyst on carbon nanotubes and Al2O3 supports
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
CO2 conversion into valuable chemicals is an attractive option to deal with the increasing CO2 concentration in the atmosphere. In this study, Cu/ZnO catalyst was synthesized on multi-walled carbon nanotubes (MWCNTs) and ...
Arabic gum as green agent for ZnO nanoparticles synthesis: properties, mechanism and antibacterial activity
(
Springer New York LLC
, 2017 , Article)
The size and morphology of ZnO nanoparticles (ZnO NPs) were controlled in the presence of the natural and green agent, Arabic gum. Lower amounts of Arabic gum showed a greater effect on the size and morphology as well as ...
Synthesis and characterization of poly(vinyl alcohol): Cloisite 20A nanocomposites
(
John Wiley and Sons Ltd
, 2017 , Article)
Polymeric nanocomposite materials are very important materials because of their promised applications. However, many of their fundamental physical, mechanical, and chemical behaviors have not been quantified. Depending on ...
Self-assembly of a surfactin nanolayer at solid-liquid and air-liquid interfaces
(
Springer Verlag
, 2016 , Article)
Surfactin, a sustainable and environmentally friendly surface active agent, is used as a model to study the adsorption of biosurfactants at hydrophobic and hydrophilic solid–liquid interfaces as well as the air–liquid ...
Multilayer-MCTDH approach to the energy transfer dynamics in the LH2 antenna complex
(
Institute of Physics Publishing
, 2017 , Article)
The multilayer multiconfiguration time-dependent Hartree method is used to study the coupled exciton–vibrational dynamics in a high-dimensional nonameric model of the LH2 antenna complex of purple bacteria. The exciton–vibrational ...
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 ...
Upgrading Calcium Bentonite to Sodium Bentonite Using Seawater and Soda Ash
(
American Chemical Society
, 2019 , Article)
In this paper, a new method is introduced to produce sodium bentonite by treating calcium bentonite using seawater to eliminate the use of freshwater and reduces the amount of soda ash required for the treatment, which ...
Photocatalytic Degradation of Pentachlorophenol Using ZnO Nanoparticles: Study of Intermediates and Toxicity
(
Springer International Publishing
, 2017 , Article)
The photocatalytic degradation of pentachlorophenol (PCP) was carried out using ZnO nanoparticles (NPs) in the presence of sunlight. The effect of different ZnO NPs sizes was synthesized by sol–gel method as well as loading ...
Direct Experimental Evidence for Photoinduced Strong-Coupling Polarons in Organolead Halide Perovskite Nanoparticles
(
American Chemical Society
, 2016 , Article)
Echoing the roaring success of their bulk counterparts, nano-objects built from organolead halide perovskites (OLHP) present bright prospects for surpassing the performances of their conventional organic and inorganic ...
