1. Natural aquatic colloidal matter : Characteristics and impact on the mobility of trace metals and organics
Abstract : Natural colloidal (< 1.0 µm) matter plays an important role for tbe transport and redistribution of water-borne substances. The aim of this work was to characterise colloidal matter from surface waters and groundwaters, and to improve on the understanding on the role of natural colloidal matter in the redistribution and mobility of trace metals.

2. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf
Abstract : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. READ MORE

3. Active Matter in a Critical State: From passive building blocks to active molecules, engines, and active droplets
Abstract : The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able to develop mechanisms to generate active motion. READ MORE

4. Nanostructured carbon materials prepared by hole-mask colloidal lithography
Abstract : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

5. Dissolved Organic Matter from a colloidal perspective
Abstract : Dissolved organic matter (DOM) is considered the most bioavailable fraction of soil, and thus play a key role in the cycling of carbon. Because of its mobility, DOM also forms the connection between terrestrial and aquatic systems, and constitutes an important vector for nutrients and contaminants. READ MORE
