    Sammanfattning :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. LÄS MER

  3. 22. Structure-Specific Vibrational Modes of Isolated Biomolecules Studied with Mid- and Far-Infrared Laser Spectroscopy

    Författare :Vasyl Yatsyna; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; far-infrared gas-phase spectroscopy; conformers; vibrational anharmonicity; infrared multiple photon dissociation; peptide structure; folded and extended peptides; hydrogen bonding;

    Sammanfattning : Biomolecular structure elucidation is crucial for our detailed understanding of various biological processes, since there is an intimate relationship between the biomolecular function and structure. In this respect, isolated biomolecules, despite being outside of their natural environment, are perfect model systems for in-depth studies of various fundamental interactions that govern the formation of biomolecular structure.

    Nyckelord :;

    Sammanfattning : Anyone who has experienced influenza or a bacterial infection knows what it means to be ill. Apart from feeling feverish, experiencing aching joints and muscles, you lose the desire to eat. Anorexia, defined as loss of appetite or persistent satiety leading to reduced energy intake, is a hallmark of acute inflammatory disease. LÄS MER
