    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; direct drive; submerged transmission; piston rod; seal housing; sealing system; laser triangulation sensor; offshore measurements; relative displacement; vibrations; tilt angle; tilting; wear estimation.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. LÄS MER

  2. 2. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Nils Olsson; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 45 degree tilt angle; dimer; antiferroelectric; fluorinated; siloxane; polymer; liquid crystal; macrocycle; ferroelectric;

    Sammanfattning : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

  3. 3. Structure determination of beam sensitive crystals by rotation electron diffraction the impact of sample cooling

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Författare :Fei Peng; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; rotation electron diffraction; structure determination; cooling; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. LÄS MER

  4. 4. Guiding of highly charged ions through insulating nanocapillaries

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Hongqiang Zhang; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; NATURAL SCIENCES Physics Atomic and molecular physics Atomic physics; NATURVETENSKAP Fysik Atom- och molekylfysik Atomfysik; fysik; Physics;

    Sammanfattning : This thesis contains experimental work on guiding of highly charged ions through insulating nanocapillaries. We have studied the time evolution of angular distributions of transmitted ions under well defined initial conditions: already charged, as well as fully discharged nanocapillaries, by using a two-dimensional position sensitive Micro Channel Plate detector with a data acquisition system working in event mode.

  5. 5. Orientation of collectors adsorbed at the ZnS/solution interface

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Margareta Lidström-Larsson; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : The separation and concentration of minerals by flotation is a well-known industrial process. In this process collectors are used to increase the hydrophobicity of the surfaces of the minerals. LÄS MER
