  1. 1. Modification and Utilization of Nanotube-vesicle Networks

    Författare :Martin Markström; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; diffusion; network; nanotube; biomimetic; hydrogel; vesicle; compartmentalization; poly N-isopropyl acrylamide ; Marangoni; liposome;

    Sammanfattning : Methods based on self-assembly and self-organization for construction of lipid bilayer networks, consisting of vesicles (3-100 μm in diameter) connected by conduits (50-300 nm in diameter), have previously been developed. Control over network geometry, topology, content, and membrane composition has been demonstrated. LÄS MER

  2. 2. Carbon Nanotube Transistors: Nanotube Growth, Contact Properties and Novel Devices

    Författare :Johannes Svensson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Carbon nanotube; chemical vapour deposition; Field effect transistor; Marangoni convection; Schottky barrier;

    Sammanfattning : Carbon nanotubes (CNTs) are envisioned to be used as the basic building blocks in future electronics due to their excellent electronic properties such as high mobility, compatibility with high-k dielectrics and small diameters resulting in advantageous electrostatics. This thesis is divided into three separate topics related to increasing the fabrication yield and performance of CNT field effect transistors (CNTFETs). LÄS MER

  3. 3. The Internal Flow in Freezing Water Droplets

    Författare :Linn Karlsson; Staffan Lundström; Anna-Lena Ljung; Jasmina Casals-Terré; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The aim of this work has been to study the internal flow in freezing water droplets on a cold surface and to investigate the different heat transfer mechanisms involved. This is an interesting topic with a great number of applications, specifically in areas where the prevention of unwanted icing is important, e.g. LÄS MER

  4. 4. Transport Modes in Nanotube-Vesicle Networks

    Författare :Michal Tokarz; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; confinement; liposome; biomimetic; micromanipulation; Vesicle; electrophoresis; network; nanotube; transport;

    Sammanfattning : Methods for construction of surface-immobilized microscopic networks of phospholipid bilayer vesicles (3-50 µm in diameter) interconnected by lipid tubes (30-150 nm in radius), have previously been developed. The networks have controlled connectivity and are well-defined with regard to container size, content, angle between nanotube extensions, and nanotube length. LÄS MER

  5. 5. Lipid Nanotubes as a Model for Highly Curved Cellular Membrane Structures

    Författare :Natalia Stepanyants; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cells and their organelles show a variety of membrane morphologies with multiplesubmicrometer features, for example, tubules, vesicles, folds and pores. The shape of thecellular membranes can dynamically change to support a variety of functions, such as cargotransport, transmission of signals between the cells, cell movement and division. LÄS MER
