    Evolution of metal catalyst during CVD synthesis of carbon nanotubes

    Matzinger, Kuno ; Grobéty, Bernard (Dir.) ; Strasser, Andreas (Codir.) ; Züttel, Andreas (Codir.) ; Vital, Andri (Codir.)

    Thèse de doctorat : Université de Fribourg, 2006.

    The revolutionary discovery of carbon nanotubes (CNT) in 1991 led to intense research activities in the domain of carbon science. The fascinating properties of these unique material has opened a great number of potential applications e.g. as electron field emitters, one-dimensional conductors, supercapacitors, reinforcing fibres or hydrogen storage. Despite these stunning technical progresses...

    Instabilité de terrain dans les Préalpes fribourgeoises (Suisse) au cours du Tardiglaciaire et de l'Holocène : influence des changements climatiques, des fluctuations de la végétation et de l'activité humaine

    Dapples, Florence ; Caron, Christian (Dir.) ; Raetzo, Hugo (Codir.) ; Kienholz, Hans (Codir.) ; Strasser, Andreas (Codir.)

    Thèse de doctorat : Université de Fribourg, 2002 ; no 1395.

    Slope instabilities such as mudflows, debris flows or landslides have lately raised much concern in Switzerland, since various major events have occurred during the last decade, resulting in major landscape disturbances, as well as costly damage to infrastructure. This demonstrated the necessity to better understand the causes and dynamics of such processes. This research work aims at defining...
