  2. 1. Structure and spectroscopy of bio- and nano-materials from first-principles simulations

    Author : Weijie Hua; Yi LUO; Mauro Stener; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soft x-ray spectroscopy; bio- and nano-materials; first-principles simulation; host-guest interaction; generalized energy-based fragmentation; Quantum chemistry; Kvantkemi; Spectroscopy; Spektroskopi; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : This thesis is devoted to first-principles simulations of bio- and nano-materials,focusing on various soft x-ray spectra, ground-state energies and structures of isolated largemolecules, bulk materials, and small molecules in ambient solutions. K-edge near-edge x-ray absorption fine structure (NEXAFS) spectra, x-ray emission spectra, andresonant inelastic x-ray scattering spectra of DNA duplexes have been studied by means oftheoretical calculations at the density functional theory level.

  4. 2. Temperature programmed studies of molecular assemblies on gold

    Author : Mattias Östblom; Sven Oscarsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the properties of ultra-thin layers of organic molecules deposited at or adsorbed onto thin films of gold. The two main experimental techniques used in this thesis work are Temperature Programmed Desorption-Infrared Reflection Absorption Spectroscopy (TPD-IRAS), an excellent technique to probe the structure and orientation of molecular layers on metallic substrates, and Temperature Programmed Desorption-Mass Spectroscopy (TPD-MS), a very useful tool to study the energetics of molecular layers and adsorbates on solid surfaces.

  5. 3. Impact of Drinking Water Treatment and Pipe Biofilms on Bacterial Dynamics in the Distribution System

    Author : Kristjan Pullerits; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drinking water treatment; Drinking water treatment plant; UV; Slow sand filter; Ultrafiltration; Drinking water distribution system; Biofilm; Biostability; Nitrification; Bacterial communities; Flow cytometry; Next-generation sequencing; 16S rRNA gene amplicon sequencing;

    Abstract : This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality. READ MORE

  6. 4. Analysis of noncovalent and covalent protein-ligand complexes by electrospray ionisation mass spectrometry

    Author : Gustav Sundqvist; Harry Brumer; Per Andrén; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; noncovalent complex; droplet fission; nano-electrospray ionisation; mass spectrometry; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis, the application of electrospray ionisation mass spectrometry (ESI-MS) to the analysis of intact proteins is demonstrated. In papers I and II, the use of ESI-MS for the analysis of noncovalent protein-ligand complexes were discussed. READ MORE
