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

    Författare :Lars Landström; Mats Boman; Peter Heszler; Joop Schoonman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; nanoparticles; laser-assisted CVD; laser ablation; emission spectroscopy; size-distribution; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : 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.

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

    Författare :Magnus Heurlin; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. LÄS MER

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

    Författare :Ignasi Velázquez i Castelló; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : 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. LÄS MER

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

    Författare :Gustav Ahlblad; KTH; []
    Nyckelord :;

    Sammanfattning : In this thesis the heterogeneous nature of thermal oxidationof polymer materials have been investigated by imagingchemiluminescence (KL). The issues of oxidation depth profilesand physical spreading of oxidation in rubbers materials andpolyamide have been addressed. LÄS MER
