1. 1. Macromolecules at Interfaces

   Författare :Helén Larsericsdotter; Sven Oscarsson; Jos Buijs; Willem Norde; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein; Adsorption; Immobilization; Surface; Surface Plasmon Resonance; SPR; Mass Spectrometry; MS; Differential Scanning Calorimetry; DSC; FT ICR; Lysozyme; Bovine Serum Albumin; BSA; Myoglobin; Globular; Kemi; Chemistry; Kemi;

   Sammanfattning : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). LÄS MER

3. 2. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

   Författare :Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

   Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER

4. 3. Strategies to explore the membrane proteome of a cell

   Författare :Gianluca Maddalo; Leopold L. Ilag; Peter James; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. LÄS MER

5. 4. Molecular-level dissolved organic matter dynamics in lakes : Constraints on reactivity and persistence

   Författare :Anne Marie Kellerman; Lars J. Tranvik; Dolly N. Kothawala; Thorsten Dittmar; Robert G. M. Spencer; Uppsala universitet; []
   Nyckelord :dissolved organic matter; DOM; dissolved organic carbon; organic matter characterization; fluorescence; PARAFAC; molecular weight; mass spectrometry; FT-ICR-MS; boreal lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Sammanfattning : Dissolved organic matter (DOM) is a central component of the global carbon cycle. Thus, small changes to the amount of DOM imported, processed and produced within lakes can have a large effect on regional carbon budgets. In addition to being a vital energy source at the base of the aquatic food web, DOM is physico-chemically reactive. LÄS MER

7. 5. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity

   Författare :Alina Mostovaya; Lars Tranvik; Colin Stedmon; Uppsala universitet; []
   Nyckelord :dissolved organic matter; DOM; dissolved organic carbon; DOC; PARAFAC; reactivity continuum model; ultrahigh resolution mass spectrometry; FT-ICR-MS; organic matter characterization; decomposition kinetics; baseline metabolism; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

   Sammanfattning : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. LÄS MER
