  5. 4. Dispersing Carbon Nanotubes: Towards Molecular Understanding

    Författare :Ricardo M. Ferreira Fernandes; Istvan Furo; Eduardo Marques; Philippe Poulin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon nanotubes; dispersion; surfactants; polymers; adsorption; liquid crystals; nuclear magnetic resonance; self-diffusion; Kemi; Chemistry;

    Sammanfattning : Carbon nanotubes (CNTs) exhibit unique and fascinating intrinsic electrical, optical, thermal or mechanical properties that lead to a plethora of potential applications in composite materials, electronics, energy storage, medicine, among others. However, the manipulation of nanotubes is not trivial and there are significant difficulties to overcome before achieving their full potential in applications. LÄS MER

  7. 5. Reaction-Diffusion kinetics of Protein DNA Interactions

    Författare :Anel Mahmutovic; Johan Elf; David van der Spoel; Pieter Rein ten Wolde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; umbrella sampling; molecular dynamics; RDME; PDE; sliding; intersegment transfer; hopping; sterics; intersegment transfer; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Transcription factors need to rapidly find one specific binding site among millions of nonspecific sites on the chromosomal DNA. In this thesis I use various aspects of reaction-diffusion theory to investigate the interaction between proteins and DNA and to explain the searching, finding and binding to specific operator sites.
