1. Cobalt in the hard metal production industry : exposure via inhalation and skin and the inflammatory response in human keratinocytes
Abstract : Cobalt is a strong sensitizer and can cause contact allergy upon both direct contact or from airborne exposure on the skin. In the skin, keratinocytes are the first cells to come in contact with the metal and will react and respond to the danger by triggering an alarm system resulting in an inflammatory response in the skin.

2. Cobalt and Nickel Bioavailability for Biogas Formation
Abstract : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. READ MORE

3. Fischer-Tropsch Synthesis over Cobalt-based Catalysts for BTL applications
Abstract : Fischer-Tropsch synthesis is a commercial technology that allows converting synthesis gas, a mixture of CO and H2, into fuels and chemicals. This process could be one of the actors in the reduction of oil dependency of the transportation sector. READ MORE

4. Deactivation of cobalt and nickel catalysts in Fischer-Tropsch synthesis and methanation
Abstract : A potential route for converting different carbon sources (coal, natural gas and biomass) into synthetic fuels is the transformation of these raw materials into synthesis gas (CO and H2), followed by a catalytic step which converts this gas into the desired fuels. The present thesis has focused on two catalytic steps: Fischer-Tropsch synthesis (FTS) and methanation. READ MORE

5. Cobalt-Chromium alloys in fixed prosthodontics
Abstract : Gold and its alloys have been the dominant framework materials in metal-ceramic constructions when substantial loss of tooth substance or missing teeth needs to be replaced. However, base metal alloys, such as cobalt-chromium (Co-Cr), have been introduced due to increased gold price. READ MORE
