Novel Graphene-Zinc Iron Oxide Composite to Enhance Ultrafiltration Membrane Performance for Water Treatment and Desalination
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The main target of membrane technologies such as the Ultrafiltration (UF), Nanofiltration (NF) and Reverse osmosis (RO) is to produce better filtration and separation of organic and inorganic substance from water as well ...
Mechanical Behavior of a Novel Nanocomposite Polysulphone - Carbon Nanotubes Membrane for Water Treatment
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Nowadays, global fresh water shortage is becoming the most serious problem affecting the economic and social development. Water treatment including seawater desalination and wastewater treatment is the main technology for ...
Electrostatic phase separation: A review
(
Institution of Chemical Engineers
, 2015 , Article Review)
The current understanding and developments in the electrostatic phase separation are reviewed. The literature covers predominantly two immiscible and inter-dispersed liquids following the last review on the topic some 15 ...
Time-resolved terahertz spectroscopy reveals the influence of charged sensitizing quantum dots on the electron dynamics in ZnO
(
Royal Society of Chemistry
, 2017 , Article)
Photoinitiated charge carrier dynamics in ZnO nanoparticles sensitized by CdSe quantum dots is studied using transient absorption spectroscopy and time-resolved terahertz spectroscopy. The evolution of the transient spectra ...
Analysis of CO2 Solubility and Absorption Heat into Aqueous 1-Diethylamino-2-propanol
(
Elsevier
, 2017 , Conference Paper)
In this work, the CO2 equilibrium solubility in 2 M 1-diethylamino-2-propanol (1DEA2P) solution were determined as function of temperature (in the range of 298-333K), and CO2 partial pressure (in the range of 8-101 kPa). ...
Regeneration Energy Analysis of Aqueous Tri-Solvent Blends Containing 2-Amino-2-Methyl-1-Propanol (AMP), Methyldiethanolamine (MDEA) and Diethylenetriamine (DETA) for Carbon Dioxide (CO2) Capture
(
Elsevier
, 2017 , Conference Paper)
This study investigated the contribution of absorption heat, sensible heat and heat of vaporization towards the regeneration energy (Qreg, kJ/g-CO2) of AMP-MDEA-DETA tri-solvent blends. The experiment was conducted at ...
A comparison of the redox properties of vanadia-based mixed oxides
(
American Chemical Society (ACS)
, 2015 , Article)
The thermodynamics of oxidation and reduction were investigated for a series of vanadium-containing oxides, including CeVO4, LaVO 4, ZrV2O7, Mg3(VO4) 2, CrVO4, AlVO4, and V2O 5, in the temperature range between 873 and 973 ...
Effect of the length of silicon nano-dot/wire on band gap
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2014 , Conference Paper)
We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ...
Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
CO2 Reduction to Renewable Hydrocarbon Fuel - Mimicking Natural Photosynthesis
(
Springer Nature
, 2017 , Article)
We report on a wide-range Density Functional Theory (DFT) investigation of the g-C3N4 photocatalysis systems combined with metals/nonmetals, especially those available in plants and involved in the natural photosynthesis ...
