Investigation of interfacial tension of surfactant in low salinity water for enhanced oil recovery application
(Master thesis, 2013)Surfactant flooding is known as a very good method to improve oil recovery. Many experimental studies in laboratories have shown the effectiveness of this method to increase the percentage of oil coming up from the core ? ... -
Investigation of metal dusting corrosion process over UNS N08800 alloy
(Journal article; Peer reviewed, 2017)Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ... -
Investigation of new polymeric membranes with controlled architecture for CO2 capture
(Master thesis, 2011)This paper discusses various characteristics of new polymeric membranes for the purpose of CO2 capture. Different types of single and copolymers were examined; especially by the sorption measurement at different pressures ... -
Investigation of New Polymeric Membranes with Controlled Architecture for CO2 Capture
(Master thesis, 2012)The capture of CO2 is of high interest in a society concerned by climate change and consequently by greenhouse gas emissions. If the amine absorption or hot potassium scrubbing are widely used, several membrane processes ... -
Investigation of Novel Dopant Materials for Enhancing Hole Transport Layer Efficiency in Organic Photovoltaics
