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 ...
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 ...
Influence of polyelectrolytes and other polymer complexes on the flocculation and rheological behaviors of clay minerals: A comprehensive review
(
Elsevier B.V.
, 2017 , Article Review)
Separation of clay minerals from industrial wastewaters is of great academic and practical importance. Current treatment techniques are either not economically viable, not environmentally friendly, or both. Thus, researchers ...
A hybrid electro-coagulation/forward osmosis system for treatment of produced water
(
Elsevier B.V.
, 2019 , Article)
Oil and gas exploration produce large volumes highly contaminated produced water (PW) which exhibits a major environmental challenge. This work investigates the application of a novel hybrid system by combining electro-coagulation ...
Evaluation of the current state and perspective of wastewater treatment and reuse in Qatar
(
Desalination Publications
, 2017 , Article)
In Qatar, many freshwater resources have already been depleted due to the overconsumption as a result of the population and economic growth. Moreover, due to the lack of sufficient sewage treatment infrastructure, Qatar ...
Corrosion behavior of API X-80 steel in hydrogen sulfide environment at different temperatures
(
National Assoc. of Corrosion Engineers International
, 2016 , Conference Paper)
The electrochemical behavior of API X-80 steel materials in 3.5% wt. of NaCI solution containing different concentration of H2S at different temperatures was studied. Potendiodynamic polarization, electrochemical impedance ...
CO2 Capture Using Hollow Fiber Membranes: A Review of Membrane Wetting
(
American Chemical Society
, 2018 , Article Review)
Hollow fiber membrane contactors have several advantages that make them a good alternative to conventional absorption processes in the gas industry, and they have attracted the interest of many researchers. However, critical ...
Potential use of mixed indigenous microalgae for carbon dioxide bio-fixation and advanced wastewater treatment
(
AIChE
, 2017 , Conference Paper)
The potential use of mixed indigenous microalgae (MIMA) as a CO2 capturing technology and treatment process for wastewaters was evaluated at two temperatures ( 25 and 30 C) and different CO2 dosage ( 0%, 5% and 15%). During ...
Photocatalytic Degradation of Pentachlorophenol Using ZnO Nanoparticles: Study of Intermediates and Toxicity
(
Springer International Publishing
, 2017 , Article)
The photocatalytic degradation of pentachlorophenol (PCP) was carried out using ZnO nanoparticles (NPs) in the presence of sunlight. The effect of different ZnO NPs sizes was synthesized by sol–gel method as well as loading ...
