  2. 2. Formation of nanoparticles by laser-activated processes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars Landström; Mats Boman; Peter Heszler; Joop Schoonman; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; nanoparticles; laser-assisted CVD; laser ablation; emission spectroscopy; size-distribution; Oorganisk kemi; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Due to the small dimensions, nanoparticles and materials consisting of nano-sized building blocks exhibit unique — mostly superior — properties, well differing from their bulk counterpart. Most of the novel properties of nanoparticles (and nanomaterials) are size-dependent, while the majority of the common gasphase methods used for generation of nanopowders result in different, usually wide, size-dispersions.

  3. 3. Aerotaxy - A Gas-Phase Nanowire Growth Technique

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Heurlin; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis an efficient nanowire fabrication technique, called Aerotaxy, is investigated. Traditional nanowire fabrication techniques include the use of a substrate as a point of nanowire nucleation which limits the amount of nanowires that can be produced per unit time. READ MORE

  4. 4. Proteins in Vacuo : Molecular dynamics studies of hen egg white lysozyme submitted to unfolding and relaxation conditions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ignasi Velázquez i Castelló; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : Electrically neutral and charged lysozyme molecules were studied with molecular dynamics (MD) techniques. Denaturation and renaturation conditions were simulated for the system in vacuo. Experimental observations of biomolecules in vacuo were related to the conformational space accessible under unfolding-relaxation conditions. READ MORE

  5. 5. Imaging chemiluminescence applied to oxidation of rubber materials and polyamide

    University dissertation from Institutionen för polymerteknologi
