  1. 1. 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

  3. 2. Compact Liquid-Jet X-Ray Sources

    Författare :Oscar Hemberg; KTH; []
    Nyckelord :liquid-jet; x-ray; EUV; plasma; electron beam; source;

    Sammanfattning : This thesis describes the development, characterization andoptimization of compact, high-brightness, liquid-jet-targetx-ray sources. Two different source types have been developedfor different wavelength regions and applications. LÄS MER

  4. 3. Rapid wetting - influence of surface geometry and fluid properties

    Författare :Susumu Yada; Fredrik Lundell; Shervin Bagheri; Minh Do-Quang; Gustav Amberg; Jacco Snoeijer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting; spreading; surface structures; droplet; contact line; two-phase flow; non-Newtonian flow; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. LÄS MER

  5. 4. A new laser-plasma X-ray source for microscopy and lithography

    Författare :Lars Rymell; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray lithography; Atomic and molecular physics; multilayer mirror; Fysicumarkivet A:1997:Rymell; Atom- och molekylärfysik; X-ray source; Laser-produced plasma; liquid droplet; debris-free; water window;

    Sammanfattning : A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. LÄS MER

  7. 5. Circulating platelets : a novel liquid biopsy source for cancer diagnostics and therapy stratification

    Författare :Lee-Ann Tjon-Kon-Fat; Jonas Nilsson; Pernilla Wikström; Michiel Pegtel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; platelets; biomarkers; liquid biopsy; therapy stratification; personalised medicine; Prostate cancer;

    Sammanfattning : As conventional tissue biopsies have several drawbacks, much effort has been directed toward the development of minimal-invasive liquid biopsy platforms for detecting and profiling cancer.Platelets are the second most abundant cells in blood and have very versatile functions both in physiological and pathophysiological conditions.
