  1. 1. Droplet Acoustofluidics for Biochemical Applications

    Författare :Zhenhua Liu; Maria Tenje; Anna Fornell; Nicole Pamme; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Droplet microfluidics; Acoustophoresis; Pico-injection; Droplet split; Biochemical reaction; In-droplet cell culture.; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : Droplet microfluidics is a promising platform for biochemical applications where compartmentalized droplets serve as individual vials. Droplets are formed by using two immiscible phases, the continuous phase and the dispersed phase, making up the droplets. LÄS MER

  2. 2. Detailed simulations of droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.

  3. 3. Droplet Velocities in a Liquid Spray

    Författare :Andreas Cronhjort; KTH; []
    Nyckelord :Liquid spray; diesel spray; droplet velocities; droplet sizes; sprayvisualization; sliced spray; particle image velocimetry; spectrum; cepstrum; cross-correlation; auto-correlation;

    Sammanfattning : A method to look into a dense liquid spray has beenevaluated. The spray was mechanically sliced to remove theobscuring parts of it, thus gaining optical access to theinternal regions and thereby allowing for visualization ofpreviously unavailable parts of the spray. LÄS MER

  4. 4. Droplet microfluidics for single cell and nucleic acid analysis

    Författare :Prem Kumar Periyannan Rajeswari; Helene Andersson Svahn; Håkan Jönsson; Martin Dufva; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Biomarker detection; Cell behavior analysis; Cell factories; Droplet microfluidics; Droplet PCR; High throughput biology; Label-free enrichment; Single cell analysis; Biotechnology; Bioteknologi;

    Sammanfattning : Droplet microfluidics is an emerging technology for analysis of single cells and biomolecules at high throughput. The controlled encapsulation of particles along with the surrounding microenvironment in discrete droplets, which acts as miniaturized reaction vessels, allows millions of particles to be screened in parallel.

    Sammanfattning : Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability.
