Inorganic chemistry consists of two groups, namely protein crystallography (Sjölin group) and research on mercury in the environment (Lindqvist group).The Sjölin group collaborate with medicine and biochemistry scientists to establish basic data for the understanding of life processes. The Lindqvist group has been dedicated to research on mercury in environmental and industrial applications during over 20 years (7 Ph. D. graduates, over 100 papers in internationally peer-reviewed journals). The group has been a partner in several international joint-research projects and inter calibrations.
