Investigation of the performance of biocompatible gas hydrate inhibitors via combined experimental and DFT methods
(
Academic Press
, 2017 , Article)
In this work, three ionic liquids (ILs) from the bio-compatible family of choline cations attached to anions of varying hydrophobicity namely: choline acetate (ChOAc), choline bistriflamide (ChNtf2), and choline chloride ...
Use of water in aiding olefin/paraffin (liquid + liquid) extraction via complexation with a silver bis(trifluoromethylsulfonyl)imide salt
(
Academic Press
, 2014 , Article)
This paper describes the extraction of C5-C8 linear -olefins from olefin/paraffin mixtures of the same carbon number via a reversible complexation with a silver salt (silver bis(trifluoromethylsulfonyl) imide, Ag[Tf2N]) ...
Development and surface modification of anion exchange membrane for enhancement of antifouling potential in electrodialys process
(
Parlar Scientific Publications
, 2018 , Article)
The membrane fouling in the course of electrodialysis (ED) is a serious problem during water treatment which results to its shorter lifetime and higher energy consumption. Here, the antifouling property of previously ...
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 ...

(
IEEE Computer Society
, 2014 , Conference Paper)
A case study on innovation and creativity in engineering design instruction has been presented. The novel approach emphases on the role of student engagement, team spirit and industry support to students. This paper presented ...
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 ...
Enhancing student learning in chemical engineering design via role play and enquiry guided learning: A case study from Qatar
(2012 , Conference Paper)
Plant design is the capstone design course taken in the senior year of a chemical engineering students at Qatar University and is spread over two semesters (Plant Design I and Plant Design II). The course content, delivery ...
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 ...
