  2. 21. Fluidic Microsystems for Micropropulsion Applications in Space

    Author : Johan Bejhed; Johan Köhler; Anders Eriksson; Greger Thornell; Thomas Laurell; Uppsala universitet; []
    Keywords : Engineering physics; microelectromechanical systems; MEMS; MST; microsystem; microfluidics; silicon; spacecraft; propulsion; space technology; Teknisk fysik;

    Abstract : Spacecraft on interplanetary missions or advanced satellites orbiting the Earth all require propulsion systems to complete their missions. Introducing microelectromechanical systems technology to the space industry will not only reduce size and weight of the propulsion system, but can also increase the performance of the mission.

  4. 22. Miniature Plasma Sources for High-Precision Molecular Spectroscopy in Planetary Exploration

    Author : Martin Berglund; Greger Thornell; Anders Persson; Felipe Iza; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEMS; MST; Optogalvanic Spectroscopy; Molecular Spectroscopy; Split-Ring Resonator; Microplasma; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : The prospect of finding life outside Earth has fascinated mankind for ages, and new technology continuously pushes the boundary of how remote and how obscure evidence we can find. Employing smaller, or completely new, types of landers and robots, and equipping them with miniature instruments would indeed revolutionize exploration of other planets and moons. READ MORE

  5. 23. Miniaturized Multifunctional System Architecture for Satellites and Robotics

    Author : Fredrik Bruhn; Jan-Åke Schweitz; Lars Stenmark; Johan Köhler; Thomas George; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space technology; Multifunctional design; Spacecraft; Robotics; Microengineering; MEMS; Exploration; Distributed intelligence; Mission Design; Rymdteknik; Space engineering; Rymdteknik;

    Abstract : This thesis describes and evaluates the design of nanospacecraft based on advanced multifunctional microsystems building blocks. These systems bring substantial improvements of the performance of nanosatellites and enable new space exploration, e.g. interplanetary science missions using minute space probes. READ MORE

  6. 24. Thermodynamic characterization of superconducting and magnetic materials using nanocalorimetry

    Author : Donato Campanini; Andreas Rydh; Christoph Meingast; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; Superconductivity; Magnetism; MEMS; Specific heat; Thermodynamics; Physics; fysik;

    Abstract : Measurement of specific heat is a powerful technique for the investigation of novel materials. Superconducting and magnetic systems, in particular, can be thoroughly characterized by studying their electronic contribution to the specific heat. READ MORE

  7. 25. Development of materials, surfaces and manufacturing methods for microfluidic applications

    Author : Carl Fredrik Carlborg; Wouter van der Wijngaart; Shoji Takeuchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microsystem technology; MEMS; microfluidics; polymers; off-stoichiometry thiol-ene; point-of-care; lab-on-chip; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis presents technological advancements in microfluidics. The overall goals of the work are to develop new miniaturized tests for point-of-care diagnostics and robust super-lubricating surfaces for friction reduction. To achieve these goals, novel materials, surfaces and manufacturing methods in microfluidics have been developed. READ MORE
