  2. 1. Calibration and quality assessment of DESCARTES : grabsampler for stratospheric tracers

    Author : Johan Arvelius; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Balloon; Carboxen; CFC; Chloro-Fluoro Carbon; Grab sampling; Halocarbon; Molecular sieve; Stratospheric tracer; Tracer; Adsorption; Ballong; Carboxen; CFC; Halogeniserade kolväten; Klor-Flourkarbon; Spårgas; Stratosfärisk spårgas; Space physics; Rymdfysik;

    Abstract : DESCARTES is a light-weight, balloon-borne grab sampler for stratospheric long-lived tracers developed at the University of Cambridge. 33 flights have been performed with two versions of the instrument at northern latitudes by the DESCARTES team at the Swedish Institute of Space Physics (IRF) in Kiruna during the years 1997-2000.

  4. 2. Modeling and simulation of intrinsically disordered proteins

    Author : Joao Henriques; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

    Abstract : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. READ MORE

  5. 3. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine

    Author : Isabelle Simonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomaterials; Surface chemistry; Ion specific effects; MOF synthesis; Odor control; Adsorption; Synthetic urine;

    Abstract : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. READ MORE

  6. 4. Terpenes Emitted to Air from Forestry and the Forest Industry

    Author : Ann-Margret Hvitt Strömvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; thermal desorption; anthropogenic terpene emissions; softwood; hydrocarbon emission; environment; phytotoxic photooxidants; adsorption sampling;

    Abstract : A major environmental concern with respect to hydrocarbon emissions is the formation of phytotoxic photooxidants. The work reported in this thesis focusses on the poorly studied anthropogenic terpene emissions from the industrial use of softwood. READ MORE
