  • Analysis of PCBs in emission samples: non ortho, mono-ortho and homolog totals by level of chlorination

    IntroductionPolychlorinated biphenyls (PCBs) are one of the most widespread persistent organic pollutants, identified in every component of the global ecosystem. A production of approximately 2 * 10 9 Kg technical PCB occurred form 1930 to the late 1970 1 and the total amount released into the environment is estimated in 370. 000 2 tonnes. Twelve of the possible 209 PCBs are non- and mono-ortho ...

  • Electronic properties of epitaxial graphene

    It has been known for almost 25 years that high temperature treatment of polar faces of SiC crystals lead to the graphitisation of the surface as a consequence of Si preferential sublimation. The group of Walt de Heer in Atlanta has proposed to use this procedure to obtain macroscopic multilayer graphene samples. This has lead to a renewal of interest for the study of the graphitic layers grown ...
