  1. 1. The diagnostic potential of the He I D3 spectral line in the solar atmosphere

    Author : Tine Libbrecht; Jaime de la Cruz Rodríguez; Jorrit Leenaarts; Göran Scharmer; Valentín Martínez Pillet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Line formation; Chromosphere; Spectro-Polarimetry; Flares; Reconnection; Astronomy; astronomi;

    Abstract : The research question of my PhD is in a way a simple one: what can observations of the He I D3 line teach us about the solar chromosphere? This optical spectral line at 5876 Å is generally formed in the upper chromosphere, and is sensitive to the local magnetic field. The He I D3 line is also indirectly sensitive to heating of the transition region and corona, since it is resulting from a transition that occurs between levels in the triplet system of neutral helium.

  2. 2. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis

    Author : Olof Johansson; Licheng Sun; Björn Åkermark; Michael D Ward; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Chemistry; Kemi;

    Abstract : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. READ MORE

  3. 3. Inorganic and Metal-Organic Framework Materials : Synthesis and structure characterization

    Author : Leifeng Liu; Junliang Sun; Xiaodong Zou; Russell Edward Morris; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; transmission electron microscopy; framework materials; porous materials; Inorganic Chemistry; oorganisk kemi;

    Abstract : Inorganic and metal-organic framework materials possessing accessible and permanent pores are receiving tremendous attention. Among them, zeolites are the most famous class due to their wide applications on petrochemistry and gas separation. READ MORE

  4. 4. Concatemerization of Synthetic Oligonucleotides, Assembly on Surface and Ligand Interactions

    Author : Lu Sun; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA formation; DNA concatemer; self-assemble; gel electrophoresis; DNA-binding; hybridization; QCM-D;

    Abstract : DNA nanotechnology has become an important research field because of its advantages in high predictability and accuracy of base-paring recognition. DNA concatemer, one of the simplest DNA constructs in shape, have been found as efficient signal amplifiers in several biosensors for different applications. READ MORE

  5. 5. Concatemerization of Synthetic Oligonucleotides
