  2. 6. Towards Controlled Growth and Applications of Carbon Nanotubes

    Author : Raluca Elena Morjan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acetylene; carbon nanotubes; carbon feedstock; chemical vapor deposition; fullerenes; dc-glow discharge plasma; growth mechanism; metal catalyst;

    Abstract : This thesis deals with growth, characterization and application of carbon nanotubes. The methods involved in the production of carbon nanotubes are thermal chemical vapor deposition (T-CVD) and plasma enhanced chemical vapor deposition (PE-CVD). READ MORE

  4. 7. The control of growth and metabolism in Caenorhabditis elegans

    Author : Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size. In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. READ MORE

  6. 9. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Author : Xiomara Holmbäck; KTH; []
    Keywords : solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Abstract : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. READ MORE

  7. 10. Elements of modeling nanoparticle growth: Surface thermodynamics and dispersive interactions

    Author : Joakim Löfgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; density functional theory; growth mechanism; gold nanorods; dispersive interactions; molecular dynamics; van der Waals forces; thermodynamics; CTAB; anisotropic nanoparticles; modeling; surface phase diagram;

    Abstract : Metal nanoparticles have in recent decades been the subject of intense research owing to their wide range of size and shape-dependent properties, which makes them interesting candidates for a variety of applications. Gold nanorods represent a particularly intriguing type of particle due to their tunable plasmonic properties. READ MORE
