A template-catalyzed: In situ polymerization and co-assembly strategy for rich nitrogen-doped mesoporous carbon
( Royal Society of Chemistry , 2018 , Article)N-doped mesoporous carbon materials are greatly useful in adsorption, catalysis and energy storage. Controlled synthesis of such materials with both high nitrogen content and desired pore structures remains a great challenge. ... -
A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory, in order to investigate the molecular characterization of Enhanced Gas Recovery (EGR) ... -
A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
( Elsevier B.V. , 2020 , Article)The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory for molecular characterization of Enhanced Gas Recovery (EGR) CO2 injection. Results show ... -
Choline chloride based natural deep eutectic solvent for destabilization and separation of stable colloidal dispersions
( Elsevier B.V. , 2021 , Article)In solid-liquid separation processes, coagulation/flocculation is one of the most popular techniques in treating wastewater, as it is efficient, simple, and economical. Consequently, the formation of a new environment ... -
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
( Trans Tech Publications , 2010 , Conference Paper)Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ... -
Effects of Structure and Environment on the Spectroscopic Properties of (3-Amino-Substituted-Thieno[2,3-b] Pyridine-2-yl)Pyridine/Quinolin-2-yl)(Phenyl)Methanones: Experimental and Theoretical Study
( Springer New York LLC , 2016 , Article)The electronic absorption, excitation and fluorescence properties of two 3-amino-substituted-thieno[2,3-b]pyridine/quinolin-2-yl)(phenyl)methanones; (referred to as compounds 1–2: where 3-amino-4,5,6-trimethyl-thieno[2,3 ... -
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 ... -
Physicochemical Insights on Alkylcarbonate-Alkanol Solutions
( American Chemical Society , 2016 , Article)Macroscopic properties and structuring at the molecular level of dialkylcarbonate + 1-alkanol mixed fluids have been studied as a function of alkyl chain lengths in 1-alkanol and dialkylcarbonate, mixture composition, and ... -
Reinforcement of polyacrylamide-co-tert-butyl acrylate base gel using nanosilica for conformance control at low and high reservoir temperatures
( Society of Petroleum Engineers (SPE) , 2020 , Conference Paper)Challenges of water shut-off, which is categorized under conformance control, are nowadays common in the oil and gas industry. The excessive water quantities produced from oil reservoirs can make the production process ...
