    Sammanfattning : The early Cambrian Buen Formation of North Greenland is celebrated for hosting one of the oldest Cambrian Burgess Shale-type deposits known to date – the Sirius Passet Lagerstätte. Further south in a shallower shelf facies belt, the Buen Formation yielded organic-walled microfossils (OWMs) that were originally described with a focus on acritarchs. LÄS MER

  4. 3. Gas Flow And Chemical Reactions In Submicron Channels

    Författare :Petronella Norberg; Michael Bowker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Through micromachining, it has become possible to realize mechanical structures of small dimensions with high reproducibility. There are numerous fields of application for such devices. The miniaturised structures have not only been used to improve existing techniques, but they have provided us with totally new possibilities. LÄS MER

    Sammanfattning : Orogenic belts are expressions of tectonic activity, often host various natural resources (e.g. petroleum and minerals reserves), and influence the society and environment through hazards (e.g. LÄS MER

  7. 5. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

    Författare :Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []

    Sammanfattning : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.
