1. Trace metal speciation in the Baltic sea
Abstract : Physicochemical speciation of metals in natural waters is very important for understanding their distribution, mobility, bioavailability and toxicity. To be able to understand the behaviour of an aqueous element and the transformation between chemical and physical species, there is a need for reliable methods that enable measurements of specific fractions of metals.

2. Iron or Copper? - Method Development and Mechanistic Studies on Cross-Coupling Reactions
Abstract : The area of catalysis has had an immeasurable impact on modern society. This has been acknowledged through several Nobel prizes during the 20th century ranging from Haber (1918) for the synthesis of ammonia to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki (2010) for palladium-catalyzed cross-coupling reactions. READ MORE

4. Colloidal carrier substances : Properties and impact on trace metal distribution in natural waters
Abstract : Colloidal (0,45 J.Im) are important constituents in the aquatic environment, due to their impact on the mobility and bioavailability of associated components (e.g. metals). READ MORE

5. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining
Abstract : Sustainable mining, including the utilisation of an ore body to its full potential, is becoming increasingly important for human society as the demand for metals increases. In order to maximise the recovery of useful metals, detailed characterisation of the ore prior to processing is vital. READ MORE
