  1. 1. Theoretical Study of Vibronic Spectra of Molecule Systems Generated by Photo- and Electronic Excitations

    Author : Ce Song; Yi Luo; Ying Zhang; KTH; []
    Keywords : Bioteknologi; Biotechnology;

    Abstract : Spectra represent fingerprints of molecules, which contain unique information about their properties. Through analyzing the spectral data, one can reveal the molecules' energy level alignments, identify their species and geometric structures, and explore relevant chemical processes and microscopic mechanisms.

  2. 2. Further development of NICE-OHMS : – an ultra-sensitive frequency-modulated cavity-enhanced laser-based spectroscopic
 technique for detection of molecules in gas phase

    Author : Patrick Ehlers; Ove Axner; Joakim Bood; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NICE-OHMS; Frequency Modulation; Cavity Enhancement; Molecular Spectroscopy; fysik; Physics;

    Abstract : Noise-immune cavity-enhanced optical heterodyne molecular spectroscopy, NICE-OHMS, is a laser-based spectroscopic detection technique that comprises the concepts of frequency modulation (FM, for reduction of 1/f-noise by detecting the signal at a high frequency) and cavity enhancement (CE, for a prolongation of the optical path length) in a unique way. Properly designed, this gives the technique an intrinsic immunity against the frequency-to-noise conversion that limits many other types of CE techniques. READ MORE

  3. 3. Improved Techniques for Protein Analysis Focusing on Membrane Proteins and Hydrophobic Peptides

    Author : Theres Redeby; Åsa Emmer; Jonas ergquist; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Integral membrane proteins; Hydrophobic peptides; Sample handling; MALDI-TOF-MS; Structured sample support; CE; fraction collection; microchannel; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis, the vital cell functions performed by integral membrane proteins (IMPs) are briefly discussed. Such proteins are under-represented in most protein studies due to the hydrophobic nature of IMPs, which seriously complicate their solubilization, sample handling, preparation, separation and analysis.

  4. 4. Molecular architecture of meiotic chromosomes

    Author : Ivana Novak; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Meiosis; Chromosome architecture; Synaptonemal complex; Cohesin complex;

    Abstract : Faithful chromosome segregation at each cell division is essential as the formation of cells with an abnormal number of chromosomes (aneuploid cells) can result in infertility, developmental defects or cancer. Aneuploidy occurs in approximately 20% of all conceptions, causing infertility and embryo death. READ MORE

  5. 5. Dynamics in Ceria and Related Materials from Molecular Dynamics and Lattice Dynamics

    Author : Anders Gotte; Kersti Hermansson; Micael Baudin; Anatoly Belonoshko; Uppsala universitet; []
    Keywords : Inorganic chemistry; molecular dynamics; diffusion; surface dynamics; ionic surfaces; Oorganisk kemi;

    Abstract : In discussions of heterogeneous catalysis and other surface-related phenomena, the dynamical properties of the catalytic material are often neglected, even at elevated temperatures. An example is the three-way catalyst (TWC), used for treatment of exhaust gases from combustion engines operating at several hundred degrees Celsius. READ MORE
