UGELSTAD LABORATORY - group for surface, colloid and polymer chemistry ~30 persons Experimental and modelling group World-class instrumentation 3rd floor K5 and PFI 1
Colloidal systems Two-phase systems: - particles/drops/bubbles dispersed in another phase or self-assembly systems - dimensions between 1nm and 1µm (i.e. interfaces important) 2
Industrial applications of Colloid Chemistry Food industry (margarine, butter, salad dressings...) Pulp and paper industry (fibers, coating, strength...) Detergent industry (cleaning processes...) Agricultural industry (formulations, insecticides...) Mineral and mining industry (flotation...) Paint industry (film formation, pigments, viscosity...) Pharmaceutical industry (drug carriers, diagnostics, implants, ) AND IN THE OIL INDUSTRY 3
