A sustainable approach to synthesize phosphonated chitosan using ball milling and its application for oilfield scale management
( Royal Society of Chemistry , 2022 , Article)For many years, the oil and gas industry has strived to develop environmentally friendly organophosphorus-based scale inhibitors. The natural polymer chitosan has recently gained significant importance for various upstream ... -
Doubly dual nature of ammonium-based ionic liquids for methane hydrates probed by rocking-rig assembly
( Royal Society of Chemistry , 2016 , Article)This work presents a systematic study of methane hydrate inhibition in the presence of five structurally variable ionic liquids (ILs) belonging to the ammonium family—viz., tetra-alkylammonium acetate (TMAA), choline ... -
Enhancing the flocculation of stable bentonite suspension using hybrid system of polyelectrolytes and NADES
( Elsevier B.V. , 2022 , Article)In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ... -
Improving the efficiency of dye sensitized solar cells by TiO2-graphene nanocomposite photoanode
( Elsevier B.V. , 2015 , Article)Nanocomposite photoanodes were prepared by addition of graphene (GR) micro-platelets to TiO2 nanoparticulate paste. TiO2/graphene based DSSCs were fabricated using Z907 photosensitizer. Transmission electron microscope was ... -
Limits and possible solutions in quantum dot organic solar cells
( Elsevier Ltd , 2018 , Article Review)In this review article, we present recent advancements in the field of organic photovoltaics (OPV) that have been achieved through the applications of quantum dots (QDs). We describe the leading experimental accomplishments ... -
Removal of emerging pharmaceuticals from wastewater by ozone-based advanced oxidation processes
( John Wiley and Sons Inc. , 2016 , Article)Thin-ply composites are currently receiving specific attention from researchers due to their capabilities to delay matrix cracking. In this paper, the aim is to design a hybrid laminate that contains both thin- and normal ... -
Synthesis and evaluation of a novel polyacrylamide functionalized nano-silica as a calcium carbonate inhibitor in upstream applications
( Elsevier B.V. , 2022 , Article)Calcium carbonate scale forms in production and injection wells, precipitating upon pressure and temperature changes, incompatible water mixing, and dehydration. Production shutdown is one of the most dramatic consequences ...
