Nanoparticles form the cornerstone in many applications of nanotechnology, and their properties are highly dependent on specific particle characteristics. We have focused on synthesis in supercritical fluids since this approach offers an energy efficient green route for the production of nanomaterials with a very high degree of control of the particle characteristics. However, in order to tailor nanoparticle characteristics insight into their formation and growth is vital and this can be achieved through in situ studies. During recent years, we have developed unique in situ reactors capable for studies of reactions in sub- and supercritical fluids. By means of Small Angle X-ray Scattering (SAXS), Wide Angle X-ray Scattering (WAXS), Total scattering and EXAFS we have obtained knowledge on the formation and growth of a range of important nanoparticles and in the talk recent results will be discussed.
Bo Brummerstedt Iversen received his PhD in Chemistry from Aarhus University in 1995. Following a postdoc appointment at UCSB, he returned to Denmark to take a position as Assistant Professor at the Department of Chemistry, Aarhus University. In 2000 he was promoted to Associate Professor and in 2004 he became Chair of Inorganic Chemistry there. Bo has during the last decade every year spent extended periods as guest professor at University of Western Australia in Perth. He is Director of the Center for Materials Crystallography, which is a Center of Excellence funded by the Danish National Research Foundation. Bo is one of the few Danish Scientists holding both a Doctor of Science degree (2002) and a Doctor of Technology degree (2010). He is a Fellow of the Royal Danish Academy of Science and Letters and he has won many awards including the Elite Researcher Award from the Danish Ministry of Science. His research interests revolve around topics in materials chemistry and materials crystallography including synthesis, characterization and application of energy materials (thermoelectrics, Li ion batteries, solar energy, catalysis), chemical bonding, electron density analysis, application of synchrotron and neutron radiation in chemistry, nanoparticles, supercritical fluids, and hydrothermal liquefaction (bio-oil). He has published ~280 papers in peer-reviewed journals.
