Ugelstad Laboratory is the group for interfacial, colloid and polymer chemistry at the Department of Chemical Engineering. The laboratory was established in 2002 in memory of late Professor John Ugelstad (known for discovering a process to manufacture monodisperse beads in the µm size range) by Professor Johan Sjöblom. Currently the group is headed by Professor Gisle Øye and brings together leading expertise in computational analysis, state of the art colloidal syntheses of nanoparticles and advanced characterization of interfacial and colloidal systems.
Interfacial and colloidal chemistry provides understanding of natural processes like formation of clouds, rain and lipid membranes; all prerequisites for life. In everyday life we encounter colloidal systems in food, cosmetics, cleaning products, pharmaceutical products and coatings, while industrial applications include transport and processing of oil and gas, wastewater treatment, mineral recovery and paper production. Interfacial phenomena are essential for the quality, efficiency and sustainability of products or processes in all these examples.
The research at Ugelstad Laboratory spans from experimental or simulation studies of dissolved molecules and assemblies of molecules at interfaces, via studies of how the resulting interfacial films influence the stability of colloidal dispersions, ending up with an understanding of how the molecular and interfacial phenomena govern large scale processes such as oil-water separation, water treatment, enhanced oil recovery, food processing, biomedicine and CO2 capture (see illustration).
