Hybrid coagulation-NF membrane processes for brackish water treatment: Effect of pH and salt/calcium concentration
(
Elsevier B.V.
, 2016 , Article)
In order to reduce membrane fouling propensity, membrane technologies in water treatment and desalination processes have been coupled with coagulation process. However, the fouling issues still persisted. It is believed ...
Thermodynamics and kinetics of CH4/CO2 binary mixture separation by metal-organic frameworks from isotope exchange and adsorption break-through
(
Elsevier B.V.
, 2018 , Article)
We combine the isotope exchange technique (IET) with the conventional Sieverts method, microcalorimetry, breakthrough experiments and multi-scale modelling to comprehensively and quantitatively investigate the thermodynamics ...
The effect of sulfur dioxide on the activity of hierarchical Pd-based catalysts in methane combustion
(
Elsevier B.V.
, 2017 , Article)
SO2 poisoning of methane oxidation over alumina-supported, Pd@CexZr1−xO2 nanoparticle catalysts was systematically studied by means of advanced PhotoElectron Spectroscopy (PES) methods. The Pd@CexZr1−xO2 units were synthesized ...
Evaluation of the Reaction Kinetics of Diethylenetriaminepentaacetic Acid Chelating Agent and a Converter with Barium Sulfate (Barite) Using a Rotating Disk Apparatus
(
American Chemical Society
, 2018 , Article)
Barium sulfate (barite) is a major oil and gas field scale formed inside the production equipment as well as in the reservoir. During drilling of oil and gas wells, barite serves as a weighting material in different drilling ...
The effect of site-specific spectral densities on the high-dimensional exciton-vibrational dynamics in the FMO complex
(
Elsevier B.V.
, 2017 , Article)
The coupled exciton-vibrational dynamics of a three-site model of the FMO complex is investigated using the Multi-layer Multi-configuration Time-dependent Hartree (ML-MCTDH) approach. Emphasis is put on the effect of the ...
Thermodynamic characterization of deepwater natural gas mixtures with heavy hydrocarbon content at high pressures
(
Elsevier
, 2015 , Article)
This paper includes high-accuracy density measurements and phase envelopes for deepwater natural gas mixtures. Mixtures primarily consist of (0.88 and 0.94) mole fraction methane and both mixtures includes heavy components ...
Carbon dioxide (CO2) capture performance of aqueous tri-solvent blends containing 2-amino-2-methyl-1-propanol (AMP) and methyldiethanolamine (MDEA) promoted by diethylenetriamine (DETA)
(
Elsevier Ltd
, 2016 , Article)
In this present research, promising aqueous amine tri-solvent blends for carbon dioxide (CO2) capture in post-combustion processes were investigated for their cyclic loadings, cyclic capacities, initial absorption rates, ...
Competitive interference during the biodegradation of cresols
(
Center for Environmental and Energy Research and Studies
, 2018 , Article)
Phenol and its methylated derivatives, cresol isomers, are hazardous pollutants that are commonly present in various industrial effluents and known to have detrimental effect on aquatic life as well as human health, due ...
Role of organic cation in modern lead-based perovskites
(
Elsevier Ltd
, 2019 , Article)
Hybrid organic-inorganic metal perovskites (ABX3, A- organic cation, B-metal ion, X-halide ion) have shown significant potential as thin-film solar cells or Dye solar cells (DSC) materials. Using a time-dependent density ...
