  2. 1. Superconducting kinetic inductance devices for nanoscale force sensing

    Author : August K. Roos; David B. Haviland; Hélène le Sueur; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optomechanics; force sensing; atomic force microscopy; kinetic inductance; superconductivity; strain; meandering nanowires; optomekanik; kraftavkänning; atomkraftsmikroskopi; kinetisk induktans; supraledning; töjning; slingrande nanotrådar; Material and Nano Physics; Material- och nanofysik;

    Abstract : In this thesis, we present a force sensor for atomic force microscopy based on cavity optomechanical principles. We explain the function, design, fabrication and characterisation of the force sensor. The mechanical part of the force sensor consists of a cantilever with a very fine tip. READ MORE

    Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE

  6. 4. Ionic liquids : The solid-liquid interface and surface forces

    Author : Nicklas Hjalmarsson; Mark W Rutland; Rob Atkin; Enrico Gnecco; KTH; []

    Abstract : Ionic liquids (ILs) present new approaches for controlling interactions at the solid-liquid interface. ILs are defined as liquids consisting of bulky and asymmetric ions, with a melting point below 373 K. Owing to their amphiphilic character they are powerful solvents but also possess other interesting properties. READ MORE
