    Author : Corina Andreoiu; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Ge detectors; gamma-ray spectroscopy; charged particle detectors; level scheme; superdeformation; Cranched Nilsson-Strutinsky approach; gamma decay-out mechanism; prompt proton decay; Condensed matter:electronic structure; Kärnfysik; Nuclear physics; magnetic and optical properties; electrical; egenskaper elektriska; magnetiska och optiska ; supraledare; magnetisk resonans; spektroskopi; Fysicumarkivet A:2002:Andreoiu;

    Abstract : High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. READ MORE

    University dissertation from Chemical Physics, Lund University

    Author : Gabor Benko; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supraledare; magnetisk resonans; spektroskopi; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Kemi; Condensed matter:electronic structure; electrical; femtosecond spectroscopy; solar cells; Chemistry; excited states; photoinduced electron transfer; transition metal complexes; nanocrystalline titanium dioxide; dye sensitization; porous semiconductor film; magnetic and optical properties;

    Abstract : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. READ MORE
