Nanocomposite Ni-TiO2 coatings produced by pulsed electroplating
(
Maney Publishing
, 2014 , Conference Paper)
Nanocomposite Ni-TiO2 coatings were prepared on mild steel substrate by pulse electroplating with controlled duty cycle and frequency. A systematic study of Ni-xTiO2 coatings with different TiO2 concentrations (x50-20 g ...
Effect of CO2 content on the natural gas production from tight gas sandstone reservoirs
(
Society of Petroleum Engineers (SPE)
, 2017 , Conference Paper)
The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas ...
Nematic opto-mechanical actuators for the fabrication of refreshable tactile systems
(2013 , Conference Paper)
Nematic elastomers are promising materials for the fabrication of actuators due to their ability to reversibly contract and expand during phase transitions triggered by external stimuli. We present a refreshable tactile ...
Sol-gel synthesis of nanocrystalline Ni-ferrite and Co-ferrite redox materials for the rmoche mical production of solar fuels
(
Materials Research Society
, 2014 , Conference Paper)
In this contribution, we report the synthesis and characterization of NixFe3-xO4 and CoxFe3-xO4 redox nanomaterials using sol-gel method. These materials will be used to produce solar fuels such as H2 or syngas from H2O ...
Solar thermochemical splitting of H2O and CO2 using nonvolatile metal oxides
(
AIChE
, 2017 , Conference Paper)
In this study, a Co ferrite/ZrO2 ceramic nanornixture was synthesized by the propylene-oxide-assisted sol-gel method. Cobalt, iron, and zirconium nitrate salts were used as the metal precursors, and ethanol and propylene ...
Aqueous ethylaminoethanol blended solvents: Promising candidates for CO2 capture
(
AIChE
, 2015 , Conference Paper)
This paper reports the investigation of effect of temperature on physico-chemical properties of formulated solvent (comprises on ethylaminoethanol, N-methyl-2-pyrollidone, and K2CO3/KHCO3) and reaction kinetics of the ...
Heat powered water pump for reverse osmosis desalination
(
TechConnect
, 2016 , Conference Paper)
Current desalination techniques are typically very energy intensive: energy consumption can account for up to 70% of the desalination costs. To improve economics of water desalination plants innovative energy efficient, ...
Study of reaction mechanism in solution combustion synthesis of transition metals
(
AIChE
, 2015 , Conference Paper)
In this paper, we investigate the reaction mechanism followed during the solution combustion synthesis of transition metals (Cu, Ni and Co) and their alloys. Metal nitrates were mixed with a choice of fuel (glycine, and ...
Assessment of carbon bio-fixation by mixed indigenous microalgae
(
AIChE
, 2018 , Conference Paper)
This study assesses the potential use of mixed Indigenous Microalgae (MIMA) for carbon capture from flue gases in a photo-bioreactor. The effect of inlet CO2 concentration on the carbon biofixation rate was investigated. ...
Solar hydrogen production via copper oxide - Copper sulfate water splitting cycle
(
AIChE
, 2015 , Conference Paper)
In this paper computational thermodynamics modeling of the solar H2 production via twostep thermochemical copper oxide - copper sulfate (CO-CS) water splitting cycle is reported. In this cycle, the first step corresponds ...
