Structural and magnetic properties of Ni1-xZnxFe 2O4 (x=0, 0.5 and 1) nanopowders prepared by sol-gel method
(2013 , Article)
A series of nanostructured Ni-Zn ferrites Ni1-xZn xFe2O4 (x=0, 0.5 and 1) with a grain size from 24 to 65 nm have been prepared with a sol-gel method. The effect of composition and sintering temperature on morphology, ...
Influence of solution chemistry on Cr(VI) reduction and complexation onto date-pits/tea-waste biomaterials
(2013 , Article)
Tea waste (TW) and Date pits (DP) were investigated for their potential to remove toxic Cr(VI) ions from aqueous solution. Investigations showed that the majority of the bound Cr(VI) ions were reduced to Cr(III) after ...
Industrial case studies in the petrochemical and gas industry in Qatar for the utilization of industrial waste heat for the production of fresh water by membrane desalination
(
Taylor and Francis Inc.
, 2013 , Article)
An investigation into the potential of using industrial low-grade waste heat in desalination using membrane distillation (MD) has been carried out. This investigation highlighted the need to work on fresh water production ...
Moisture and temperature dependence of the dielectric properties of pharmaceutical powders
(2013 , Article)
The dielectric properties of pharmaceutical powder–(paracetamol, aspirin, lactose, maize starch, adipic acid) solvent (water) mixtures were measured at 2,450 MHz at a range of moisture contents (0–1.0 kg kg−1, dry basis) ...
Integrating ethics into the chemical engineering curriculum: The Qatar University experience
(2013 , Conference Paper)
Qatar is growing at an unprecedented rate due to the utilization of its vast gas reserves. The country's wealth stems from oil, gas and petrochemical industries. Engineers are in high demand in all specializations and Qatar ...
Viscous behavior of imidazolium-based ionic liquids
(2013 , Article)
The viscosity of four imidazolium-based ionic liquids is analyzed as a function of pressure and temperature. Experimental measurements were carried out using an electromagnetic moving piston viscometer in the 303-353 K and ...
Removal of carbamazepine from water by a novel TiO2-coconut shell powder/UV process: Composite preparation and photocatalytic activity
(2013 , Article)
A novel TiO2-coconut shell powder (TCNSP) composite, prepared by the controlled sol-gel method with a subsequent heat treatment, was investigated as an innovative photocatalytic absorbent for the removal of carbamazepine ...
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(2013 , Article)
Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ...
High pressure CO2 absorption studies on imidazolium-based ionic liquids: Experimental and simulation approaches
(2013 , Article)
A combined experimental-computational study on the CO2 absorption on 1-butyl-3-methylimidazolium hexafluophosphate, 1-ethyl-3-methylimidazolium bis[trifluoromethylsulfonyl]imide, and 1-butyl-3-methylimidazolium ...
