  1. 41. Microsystems for Harsh Environments

    Författare :Stefan Knaust; Lena Klintberg; Klas Hjort; Fredric Ericson; Samuel Marre; Uppsala universitet; []
    Nyckelord :Microsystems; harsh environments; high pressures; high temperatures; supercritical microfluidics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : When operating microsystems in harsh environments, many conventionally used techniques are limiting. Further, depending on if the demands arise from the environment or the conditions inside the system, different approaches have to be used. LÄS MER

  3. 42. Investigations of Strong Light-Matter Interactions in Nanophotonic Systems

    Författare :Michael Stührenberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoluminescence; strong coupling; localized surface plasmon resonance; bipyramids;

    Sammanfattning : Noble metal nanoparticles can support localized surface plasmon resonances (LSPR), thus behaving as open optical resonators. Outstanding optical properties as well as a subwavelength mode volume make plasmonic nanoparticles a promising platform for enhanced light-matter interactions. LÄS MER

  4. 43. Detecting the dynamics of single biomolecules

    Författare :Stefan Wennmalm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is concerned with the detection of single biomolecules. Through detection of individual molecules it can be clarified whether a behavior which has been observed in a population is representative for all molecules. For detection confocal fluorescence microscopy was used, in particular Fluorescence Correlation Spectroscopy (FCS). LÄS MER

  5. 44. Aspects of Structural Evolution in Cemented Carbide – Carbide Size, Shape and Stability

    Författare :Ida Borgh; Joakim Odqvist; Peter Hedström; Annika Borgenstam; Jean-Michel Missiaen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; Ti; Zr C; Coarsening; Phase separation; C-activity; initial WC powder size; electron backscattered diffraction; microscopy; X-ray diffraction;

    Sammanfattning : Cemented carbide is a composite material used in applications like cutting tools and rock drilling inserts. The material commonly consists of WC grains embedded in a Co-rich binder phase and the material properties strongly depend on the WC grain size. LÄS MER

  7. 45. Transmission Electron Tomography and In-situ Analysis of Nanowires

    Författare :Axel Persson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy TEM ; Electron tomography; Nanowires NWs ; Aerotaxy; In-situ;

    Sammanfattning : As semiconducting nanowires have promising applications for materials science, nanoelectronics and photovoltaic devices, absolute control of their structure, morphology and composition is a prerequisite for their functionality. Nanowires, grown through the vapor-liquid-solid (VLS) method, exhibit a complex relationship between their liquid seed particle and what properties, such as the aforementioned ones, the wire adopts in the end.
