    Författare :Minshu Xie; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanowire junctions; on-scalp MEG; Bicrystal grain boundary; magnetoencephalography; YBCO; magnetometers; high-Tc SQUIDs;

    Sammanfattning : This thesis describes the development of high critical temperature superconducting quantum interference device (high-Tc SQUID) magnetometers based on bicrystal grain boundary and nanowire junctions for the potential use in on-scalp magnetoencephalography (MEG), which is a new generation MEG technique with reduced sensor-to-subject standoff distances.MEG is a method of mapping neural dynamics in the human brain by recording the magnetic fields produced by neural currents.

  3. 17. Plasmonics with a Twist: from Single Particles to Metasurfaces

    Författare :Robin Ogier; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colloidal lithography; localized surface plasmons; circularly polarized light; metsurfaces; nanofabrication; chirality; optical trapping;

    Sammanfattning : Nanophotonics deals with how electromagnetic fields can be confined and squeezed to orders of dimensions below the light wavelength. Plasmonics, one of the fields of nanophotonics, study collective free electron oscillations driven by light in metallic nanostructures and interfaces. LÄS MER

  4. 18. Development of the mineralogical path for geometallurgical modeling of iron ores

    Författare :Mehdi Parian; Antti Remes; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The demands for more effective utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross discipline called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

  5. 19. Lärares transformering av teknikämnet : Om lärares attityder till ämnet och syn på teknisk kunskap i teknikundervisningen

    Författare :Charlotta Nordlöf; Jonas Hallström; Gunnar Höst; Arnold Pears; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technology education; Technology; Teachers; Attitudes; Knowledge; Transformation; Teknikundervisning; Teknik; Lärare; Attityder; Kunskap; Transformering;

    Sammanfattning : En lärare behöver i sitt arbete göra val och fatta beslut som påverkar vilken undervisning eleverna får möta. Skolämnet teknik, som är ett av grundskolans obligatoriska ämnen redan från lågstadiet, har sina specifika förutsättningar och traditioner. LÄS MER

  7. 20. Single DNA Molecule Analysis – New Tools for Medical Diagnosis

    Författare :My Nyblom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical DNA mapping; DNA damage; DNA; single-molecule analysis; fluorescence microscopy; antibiotic resistance; nanofluidics; genetics;

    Sammanfattning : The DNA molecule, the blueprint of life, contains an enormous amount of information. The information is coded by the combination of four bases; adenine, cytosine, guanine, and thymine, that, together with the sugar-phosphate backbones, make up the DNA double helix. LÄS MER
