Findings from University of Bergen in the Area of Nanoparticles Reported

June 27, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Data detailed on Nanoparticles have been presented. According to news originating from Bergen, Norway, by VerticalNews correspondents, research stated, "There is booming interest in the application of nanoparticles for enhanced oil recovery. In this work, a polymer nanoparticle that is generated by cross-linking a high-molecular weight partially hydrolyzed polyacrylamide with aluminum(III) and known as linked polymer solution (LPS) has been studied."

Our news journalists obtained a quote from the research from the University of Bergen, "The size and conformational state of LPS particles are influenced by the concentration of Al(III). To the best our knowledge, there is no current established method for determining the conformational state, i.e., single coiled particle, coil aggregates, or gel, for a polymer solution with a high molecular weight (>10 X 10(6) Da) and a low concentration (

According to the news editors, the research concluded: "Ultimately, networked weak gels are formed by coil aggregates (intermolecular cross-linking) above the threshold concentration."
