  1. 26. Liquid metal microscale deposition for soft and stretchable skin-like electronics : Providing a soft and gentle contact to living beings

    Författare :Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser patterning; sacrificial mask; liquid metal; strain sensor; skin movement; masking; shrink film; 3D conformal masking; liquid metal particles; soft electronics; stretchable electronics; compliant electronics; skin-like electronics; epidermal electronics; micro-heater; particle sintering; enteroendocrine cells; localized ectopic expression; wettability; flexography printing; conformal transfer printing; hydro printing; plant physiology; drosophila;

    Sammanfattning : Skin-like electronics could provide a soft and gentle contact with living beings for perceiving and delivering the information of pressure, strain, temperature with higher spatial resolution and sensitivity than our skin, without disturbing the user. Gallium-based liquid metal (LM) is an excellent material for soft and stretchable skin-like devices, since it has high electrical and thermal conductivity, flowability, and self-healable capability.

  3. 27. Fluid Mechanics of Solid-Liquid Suspensions – An Experimental and Numerical Study

    Författare :Torbjörn Virdung; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiphase; soalescence; confined jet; computational fluid dynamics; stirred vessel; laser doppler velocimetry; particle image velocimetry; solid-liquid suspension; pitched blade; gas-liquid;

    Sammanfattning : Multiphase flows are common in many applications in chemical, mineral, biochemical and several other process industries. Examples of equipment in which multiphase flows are encountered are stirred vessels and multiphase jets, in which suspensions are agitated by an impeller in the former case and distributed through a nozzle in the latter.

  4. 28. Devlopment and relaxation of orientation in liquid crystalline polymers : transport properties of liquid crystalline polymer blends

    Författare :Göran Wiberg; KTH; []
    Nyckelord :;

    Sammanfattning : In this thesis different types of liquid crystallinepolymers have been investigated with respect to build up andrelaxation of orientation. The potential of making new barriermaterials using liquid crystalline polymer blends was alsostudied. LÄS MER

  5. 29. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

    Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

    Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER

  7. 30. Electrochromatography and liquid chromatography : Microtechniques, instrumentation and applications

    Författare :Christer Ericson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : The thesis focuses on the design of efficient chromatographic and electrochromatographic microcolumns where a continuous bed is polymerized in situ in a capillary or a channel in a microchip device. In our technique, a solution of selected monomers is simply sucked or pressed into the capillary or microchip channel for subsequent polymerization. LÄS MER
