    Abstract : Absorption spectroscopy is a powerful scientific tool for non-invasive and remote sensing applications ranging from atmospheric monitoring to astrophysics. In spectroscopic detection schemes it is necessary to have spectral models for any molecular species to be detected or quantified. READ MORE

  6. 4. Weak Atomic Interactions

    Author : Peter Schef; Sven Mannervik; Juliet C. Pickering; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metastable states; forbidden transitions; laser probing; hyperfine structure; LRDR; Atomic physics; Atomfysik;

    Abstract : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. READ MORE

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

    Author : Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : 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.
