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

   Author : Erik Marklund; David van der Spoel; Albert Heck; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; Physics; 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

4. 2. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

   Author : Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

   Abstract : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. READ MORE

5. 3. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures

   Author : Joachim Walewski; Förbränningsfysik; []
   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

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

   Author : Sander van den Hark; Chalmers tekniska högskola; []
   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

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

   Author : Dogan Ergun Oner; Chalmers tekniska högskola; []
   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
