( 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 ... -
Removal of Oil Content from Oil-Water Emulsions Using Iron Oxide/Bentonite Nano Adsorbents
( Elsevier Ltd , 2020 , Article)Water scarcity is a challenge that is faced worldwide to secure sustainable good quality water resources. Produced water, associated with the production of gas and oil, usually comes as oil contaminated water, creating ... -
Reprint of “The effect of site-specific spectral densities on the high-dimensional exciton-vibrational dynamics in the FMO complex”
( Elsevier B.V. , 2018 , Article)© 2017 Elsevier B.V. The coupled exciton-vibrational dynamics of a three-site model of the FMO complex is investigated using the Multi-layer Multi-configuration Time-dependent Hartree (ML-MCTDH) approach. Emphasis is put ... -
Review of Iron Sulfide Scale Removal and Inhibition in Oil and Gas Wells: Current Status and Perspectives
( American Chemical Society , 2021 , Article Review)Iron sulfide scale is one of the main types of inorganic scales that block oil and gas wells. Iron sulfide has polymorph crystallinity structures, which complicate its dissolving and inhibition. Hydrochloric acid (HCl) is ... -
Review on recent advances in polythiophene based photovoltaic devices
( Elsevier Ltd , 2016 , Article Review)Discovery of conducting polymer introduced us to the total polymeric solar cells (PSC). During the last decade, power conversion efficiency (PCE) of these solar cells has increased from 1% to 11.5% (with the bulk heterojunction ... -
Review on Surfactant Flooding: Phase Behavior, Retention, IFT, and Field Applications
( American Chemical Society , 2017 , Article Review)Surfactant flooding is an important technique used in enhanced oil recovery to reduce the amount of oil in pore space of matrix rock. Surfactants are injected to mobilize residual oil by lowering the interfacial tension ... -
Rheological and thermal properties of novel surfactant-polymer systems for EOR applications
