The impact of mechanical shear on membrane flux and energy demand
(
Elsevier B.V.
, 2016 , Article Review)
The use of forced mechanical shear for both disc membranes (rotating and vibrating disc filtration, RDF and VDF respectively) and hollow fibres (vibrating HF membranes, VHFM) is reviewed. These systems have been extensively ...
Heat transfer enhancement of nanofluids using iron nanoparticles decorated carbon nanotubes
(
Elsevier Ltd
, 2016 , Article)
Enhancing heat transfer in thermal fluid systems can contribute significantly towards the improvement of thermal efficiency resulting in reducing energy consumption and hence carbon emission. Conventional fluids like water ...
Synthesis and characterisation of Co2+-incorporated ZnO nanoparticles prepared through a sol-gel method
(
Elsevier B.V.
, 2016 , Article)
The properties of ZnO nanoparticles were modified by doping them with cobalt ions (Co2+) in various compositions through a sol-gel route. The Co2+-doped ZnO nanoparticles were characterised using X-ray diffraction (XRD), ...
Enhancing oil removal from water using ferric oxide nanoparticles doped carbon nanotubes adsorbents
(
Elsevier B.V.
, 2016 , Article)
Oil contaminated water is one of the challenges in water resources management. It is crucial to remove the oil droplets from water in order to meet the discharge regulations set by the environmental authorities. Carbon ...
Modification of Pd/CeO2 catalyst by Atomic Layer Deposition of ZrO2
(
Elsevier
, 2016 , Article)
Modification of a 1 wt% Pd/CeO2 catalyst by Atomic Layer Deposition of thin ZrO2 films was studied. Calcination of the unmodified Pd/CeO2, prepared by precipitation of aqueous Ce(NO3)3 solutions, with Pd added by impregnation, ...
A mathematical model for carbon fixation and nutrient removal by an algal photobioreactor
(
Elsevier Ltd
, 2016 , Article)
A comprehensive mathematical modeling method for Chlorella vulgaris (Cv) has been developed to assess the influence of nutrient concentration (total nitrogen TN= 28-207 and total phosphorus TP= 6-8mgL 1) and irradiation ...
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 ...
Hybrid coagulation-NF membrane process for brackish water treatment: Effect of antiscalant on water characteristics and membrane fouling
(
Elsevier B.V.
, 2016 , Article)
Antiscalants have been used to inhibit the formation of scales and reduce the risk of membrane scaling. However, issues such as the increased of biofouling tendency and contradictory observations of organic fouling propensity ...
In situ DRIFTS Studies on Cu, Ni and CuNi catalysts for Ethanol Decomposition Reaction
(
Springer New York LLC
, 2016 , Article)
Catalyst nanopowders containing copper and nickel were synthesized using solution combustion synthesis method for hydrogen production from ethanol decomposition. Detailed in situ DRIFTS studies were conducted on three ...
Synthesis of new amines for enhanced carbon dioxide (CO2) capture performance: The effect of chemical structure on equilibrium solubility, cyclic capacity, kinetics of absorption and regeneration, and heats of absorption and regeneration
(
Elsevier B.V.
, 2016 , Article)
This work focused on the synthesis of new tertiary amines by varying the alkyl chain length with/without hydroxyl group in the structure. The effect of chemical structure of newly synthesized tertiary amines; 4-(dimethyl ...
