  1. 1. Gas-Phase Protein Structure Under the Computational Microscope Hydration, Titration, and Temperature

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Marklund; David van der Spoel; Albert Heck; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. READ MORE

  2. 2. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures

    University dissertation from Lund Institute of Technology

    Author : Joachim Walewski; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluiddynamik; Gaser; plasma; Maskinteknik; vibration and acoustic engineering; vacuum technology; hydraulics; vibrationer; vakuumteknik; statistical inference; Mechanical engineering; polarisation spectroscopy; diamond CVD; quantitative spectroscopy; hydraulik; gas phase kinetics; plasmas; fluid dynamics; Gases; Fysik; akustik; Physics; Fysicumarkivet A:2001:Walewski;

    Abstract : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. READ MORE

  3. 3. The Use of Supercritical Fluids to Reduce the Number of Phases in Catalytic Hydrogenation: The Reaction of Fatty Acid Methyl Esters to Fatty Alcohols

    University dissertation from Lund Institute of Technology

    Author : Sander van den Hark; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fatty alcohols; single phase; deactivation; mass transport; phase reduction; supercritical fluids; hydrogenation; propane; kinetics; catalysis;

    Abstract : Supercritical fluids have unique properties - between those of liquids and gases - making them attractive reaction media. In this study, propane was used to change a heterogeneous catalyst from being substrate-covered in gas-liquid hydrogenation reactions into hydrogen-covered in our experiments. READ MORE

  4. 4. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study

    University dissertation from Lund Institute of Technology

    Author : Dogan Ergun Oner; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide nucleation and growth; dissociative adsorption; metal oxidation; Monte Carlo simulations; Al 111 ; kinetics; aluminium; surface oxidation;

    Abstract : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. READ MORE

  5. 5. Molecular investigations of atmospherically relevant interface processes: ice formation and water accommodation on ice and organic surfaces

    University dissertation from Lund Institute of Technology

    Author : Xiangrui Kong; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosphere; kinetics; Environmental molecular beam; ice nucleation; supersaturation; accommodation coefficient; phase transition; alcohols; green chemistry;

    Abstract : Clouds and aerosols play important roles in the climate system by affecting on atmospheric chemistry, the radiation budget of the atmosphere, and the water cycle including the formation of precipitation. Climate models with predictive power require quantitative descriptions of aerosols and clouds, but several key processes remain to be fully understood. READ MORE
