  1. 6. Piezoactuators for Microfluidics : Towards Dynamic Arraying

    Författare :Tobias Lilliehorn; Stefan Johansson; Göran Stemme; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Microfluidics can be used to increase performance, reduce reagent consumption and increase throughput in chemical analysis. With the forthcoming development of more advanced microfluidic systems, the integration of actuating elements becomes essential, giving the ability to control and manipulate fluid flow as well as sample or other components.

  3. 7. Piezoactuators for Miniature Robots

    Författare :Urban Simu; Jean-Marc Breguet; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

    Sammanfattning : Challenges in the realisation of a miniature robot are both to handle the complexity of such a system, and to cope with effects of the actual reduction in physical size of all the parts. In particular, the mechanisms for locomotion have to be analysed. LÄS MER

  4. 8. Mechanical Properties and Deformation Behaviour of Polymer Materials during Nanosectioning : Characterisation and Modelling

    Författare :Fengzhen Sun; Kristofer Gamstedt; Kai Cheng; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanosectioning; Fracture toughness; Adiabatic shearing; Shear band; Nanosectioning; Glassy polymer; Nanocomposite;

    Sammanfattning : Research in local fracture processes and micro-machining of polymers and polymer-based composites has attracted increasing attention, in development of composite materials and miniaturisation of polymer components. In this thesis, sectioning (machining) of a glassy polymer and a carbon nanotube based composite at the nanoscale was performed by an instrumented ultramicrotome. LÄS MER

  5. 9. Acoustic manipulation of cells and microbeads in droplet microfluidics

    Författare :Anna Fornell; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Droplet microfluidics; Enrichment; Lab-on-a-chip; Particle manipulation; Ultrasound;

    Sammanfattning : Droplet microfluidics has emerged as a promising platform for miniaturisation of biological assays on-chip. In droplet microfluidics small water droplets (nL-pL) surrounded by an immiscible carrier oil are generated at high throughput. LÄS MER
