  2. 6. On the Environmental Relevance of Platinum Group Elements

    Author : Sebastien Rauch; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platinum; ICP-MS; automobile emission; catalyst ageing; palladium; laser ablation; urban particles; bioaccumulation; rhodium;

    Abstract : It has recently been demonstrated that platinum group elements (PGE) are released from automobile catalysts into the environment, raising concern over ecological and human health risks. However, there is still a lack of knowledge regarding the dispersion and transformation of PGE in the environment and it is therefore difficult to assess potential risks. READ MORE

  5. 8. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments

    Author : Louise Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NO oxidation; Monte Carlo simulations; platinum oxide; kinetic modelling; NOx storage; barium oxide; environmental catalysis; NOx removal; platinum; flow reactor measurements;

    Abstract : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. READ MORE

  6. 9. Copper-transporting proteins and their interactions with platinum-based anticancer substances
