(Master thesis, 2015-06-01)In this project, the combining of photovoltaic cells and supercapacitors into a single, photocapacitor system, was studied. A complete photocapacitor system of commercial components was put together, and characterized. The ... -
Photocatalytic TiO2/rGO/CuO Composite for Wastewater Treatment of Cr(VI) Under Visible Light
(Journal article; Peer reviewed, 2020)The harm of chromium pollution to the environment has caused a widespread concern; hexavalent chromium is a toxic, cancerogenic, and genetically mutagenic contaminant to the human body; by contrast, trivalent chromium is ... -
Photodegradable antimicrobial agents - synthesis, photodegradation, and biological evaluation
(Journal article; Peer reviewed, 2021)Multi-drug resistant (MDR) bacteria are already a significant health-care problem and are making the combat of infections quite challenging. Here we report the synthesis of several new compounds containing an ethanolamine ... -
Physical Chemistry of Mechanisms for Low Salinity Waterflood
(Master thesis, 2013-10-23)Low salinity injection as an alternative EOR method to enhance the production of reserves has for decades been investigated. Increasing evidence that reduction in brine salinity can cause a significant impact on the oil ... -
Physico-Chemistry Characterization of Sulfonated Polyacrylamide Polymers for Use in Polymer Flooding
(Doctoral thesis, 2010-06-01)Hydrolyzed polyacrylamide polymer (HPAM) as a feasible and effective viscosifier has been fully studied and used for polymer flooding processes in several oil field, e.g. Daqing oil field. It has been shown that Hydrolyzed ... -
Polar Components in Crude Oils and Their Correlation to Physiochemical Properties.
(Master thesis, 2016-06-01)The composition and properties of crude oils have been subjected to much scrutinization over the past decades due to the decreasing oil quality and thus increasingly difficult oil recovery. The physical properties of crude ... -
Polymer flow in porous media: Relevance to Enhanced Oil Recovery
(Peer reviewed; Journal article, 2018-07-10)Polymer flooding is one of the most successful chemical EOR (enhanced oil recovery) methods, and is primarily implemented to accelerate oil production by sweep improvement. However, additional benefits have extended the ... -
Polymer Injectivity : Experimental Studies of Flow in Porous Media for EOR Polymers
(Doctoral thesis, 2021-02-12)Despite the maturity of the polymer flooding process that is applied in enhanced oil recovery (EOR) technologies, the core of the process, which is the flow of the polymer in porous media, is poorly understood. The types ... -
Polymer Injectivity Test Design Using Numerical Simulation
(Journal article; Peer reviewed, 2020-04-03)Polymer flooding is an enhanced oil recovery (EOR) process, which has received increasing interest in the industry. In this process, water-soluble polymers are used to increase injected water viscosity in order to improve ... -
