  1. 21. Carbon-nanotube-based nanoelectromechanics

    Författare :Magnus Jonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electromechanical instabilities; multi-mode excitations; NEMS; suspended carbonnanotubes; Nanoelectromechanicalsystems; non-linearresonances; nanorelay; carbon nanotubes; surface forces;

    Sammanfattning : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. LÄS MER

    Författare :Reza Zandi Shafagh; Klas Tommy Haraldsson; Wouter van der Wijngaart; Niels Bent Larsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanostructuring; thiol-ene; OSTE; electron beam lithography EBL ; reaction injection molding RIM ; nanoimprint lithography NIL ; BioNEMS; QCM; digital bioassay; protein patterning; Lab-on-a-chip; polymer;

    Sammanfattning : Improving the health and well-being of humankind does not only constitutepart of our moral codes, but is also enlisted as the number three goal ofthe 2030 agenda for sustainable development set by the UN. Fulfilling suchobjective in the regions of resource-poor settings or for age groups with morevulnerability to infectious agents demands immediate actions. LÄS MER

  4. 23. Mechanical properties of carbon nanotubes and nanofibers

    Författare :Henrik Jackman; Krister Svensson; Pavel Krakhmalev; Håkan Olin; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atomic force microscopy; bending; carbon nanotubes; deformation; scanning electron microscopy; Young s modulus; carbon nanofibers; mechanical properties; Physics; Fysik;

    Sammanfattning : Carbon nanotubes (CNTs) have extraordinary electrical and mechanical properties, and many potential applications have been proposed, ranging from nanoscale devices to reinforcement of macroscopic structures. However, due to their small sizes, characterization of their mechanical properties and deformation behaviours are major challenges. LÄS MER

  5. 24. Electromechanical Instability in Suspended Nanowire-Based NEMS

    Författare :Fabio Santandrea; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NEMS; Shuttle instability; Coulomb blockade; Carbon Nanotubes; Electronic Transport; Nonlinear Dynamics;

    Sammanfattning : "Nanoelectromechanical systems'' (NEMS) are a class of nanometer-sized mechanical structures coupled to electronic device of comparable dimensions. Their peculiar features make them interesting both from the technological and fundamental research viewpoints. LÄS MER
