Observations of hydrographic properties, dissolved oxygen (DO) and chlorophyll-A (Chl-a) (phytoplankton biomass) within the exclusive economic zone (EEZ) of Qatar (central Arabian Gulf)
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
In situ observations of physical, chemical, and biological parameters of the Qatari water column were conducted to understand the temporal (seasonal) and spatial (regional) variability in the vertical and horizontal ...
Thermal properties of phase-change materials based on high-density polyethylene filled with micro-encapsulated paraffin wax for thermal energy storage
(
Elsevier Ltd
, 2015 , Article)
Microcapsules consisting of paraffin wax cores with a melting point of approximately 42 °C and a melamine-formaldehyde resin shell were synthesized using in situ polymerization. These microcapsules have a uniform distribution ...
E-cadherin/catenin complex modulations in human oral cancer
(
Springer Netherlands
, 2015 , Book chapter)
Oral cancer is a common neoplasm in both male and female worldwide; the incidence and mortality of this cancer have increased over the past decades. Cancer metastasis is a major cause of morbidity and mortality in oral ...
Electrocoalescence of water drop trains in oil under constant and pulsatile electric fields
(
Institution of Chemical Engineers
, 2015 , Article)
This study addresses the effectiveness of constant and pulsed DC fields in promoting coalescence of dispersed water drops in an oil-continuous phase. For this purpose, a train of drops of relatively uniform size is injected ...
Experimental determination of carbamate formation and amine protonation constants in 3-amino-1-propanol-CO2-H2O system and their temperature dependency
(
Elsevier
, 2015 , Article)
The equilibrium constant for the formation of carbamate in 3-amino-1-propanol-CO2-H2O system was evaluated at different CO2 loadings, different temperature values, and different amine protonation constant. The studied ...
Kinetics of CO2 reaction with solutions of n-methyl-diethanolamine mixed with selected amino acids using stopped flow technique
(
AIChE
, 2015 , Conference Paper)
Kinetics of CO2 reactions with blended solutions of N-methyldiethanolamine (MDEA) and salts of Glycine and Taurine are presented in this work. The obtained results show that the new blended solutions could be promising ...
Reaction kinetics of some important alkanolamines with carbon dioxide in aqueous solutions using stopped flow technique
(
AIChE
, 2015 , Conference Paper)
The kinetics of the reactions between aqueous solutions of carbon dioxide and Aminomethylpropanol (AMP), Aminobutanol (AB), Aminopropanol (AP), Diethanolamine (DEA) and Ethanolamine (MEA) were investigated over a temperature ...
Recent progress and new developments in post-combustion carbon-capture technology with amine based solvents
(
Elsevier
, 2015 , Article Review)
Currently, post-combustion carbon capture (PCC) is the only industrial CO2 capture technology that is already demonstrated at full commercial scale in the TMC Mongstad in Norway (300,000 tonnes per year CO2 captured) and ...
Thermodynamic characterization of deepwater natural gas mixtures with heavy hydrocarbon content at high pressures
(
Elsevier
, 2015 , Article)
This paper includes high-accuracy density measurements and phase envelopes for deepwater natural gas mixtures. Mixtures primarily consist of (0.88 and 0.94) mole fraction methane and both mixtures includes heavy components ...
CO2 sorption kinetics of scaled-up polyethylenimine-functionalized mesoporous silica sorbent
(
American Chemical Society
, 2015 , Article)
Two CO2 solid sorbents based on polyethylenimine, PEI (Mn ∼ 423 and 10K), impregnated into mesoporous silica (MPS) foam prepared in kilogram quantities via a scale-up process were synthesized and systematically characterized ...
