1. Alkylation and Hydrodearomatization over Zeolite cCatalysts
Sammanfattning : The alkylation of aromatic compounds is widely used in the large-scale synthesis of petrochemicals, and a great variety of fine chemicals and intermediates. Acid catalysts used for alkylation of aromatic hydrocarbons are Brønsted acids containing acidic protons. LÄS MER
2. Effects of Environment on Charge Recombination in Organo-Metal-Halide Perovskite Observed by Photoluminescence Microscopy and Spectroscopy
Sammanfattning : Organo-metal-halide (OMH) perovskites form a new class of materials withperovskite crystal structure ABX3 where A is an organic molecule, B is lead (Pb)and X is a halide atom (I or Br). OMH perovskite semiconductors have been widely used in photovoltaics due to their very strong absorption of sun light, very suitable electrical properties, and the ease of preparation. LÄS MER

4. Characterization of antibodies against Helicobacter pylori
Sammanfattning : H. pylori is associated with the development of peptic ulcer, gastritis, and gastric cancer. Eradication of H. pylori by antibiotic treatment gives a healing of peptic ulcer and gastritis. LÄS MER
5. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus
Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.
