  1. 16. Characterization of Aerosols Related to Occupational and Public Environments as Applied to Isocyanates and Road Wear

    Författare :Andreas Dahl; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis was to characterize a personal denuder/filter sampler for isocyanate aerosol and to study the emission of airborne particles from the interaction between studded tires and pavements. Both types of aerosols are highly relevant for health studies in public and occupational environments. LÄS MER

  3. 17. Spin and magneto transport in van der Waals heterostructures of graphene with ferromagnets

    Författare :Bogdan Karpiak; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The increasing demand for information and communication technologies has augmented the requirements of electronic devices with improved speed, sensitivity, and reduced power consumption. The utilization of novel electronic materials and the use of the spin degree of freedom as a state variable for information processing and storage are expected to fulfill these demands. LÄS MER

  4. 18. Electron transport studies in epitaxial graphene on SiC

    Författare :Michael Winters; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Furthermore, the dispersion in graphene k is light-like for graphene monolayers implying that electron transport would behave relativistically. If vsat = vf could be achieved in the material, then it is theoretically possible to achieve THz performance in long channel devices. Despite the nice theoretical picture, Nature is hardly so forthcoming. LÄS MER

  5. 19. Epistemology of practice and its consequences in practice : Educating for knowing-in-action in working life

    Författare :Marie Moström Åberg; Susanna Toivanen; Kerstin Isaksson; Ing-Marie Andersson; Gunnar Rosén; Lena Wilhelmson; Tina Forsberg; Camilla Thunborg; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Working Life Studies; arbetslivsvetenskap;

    Sammanfattning : Education and competence development are of increased interest in today’s society and organizations, to increase the wellbeing, lifelong learning, and mobility of the labor force, and contribute to companies’ global competition. As a consequence, formal and informal education is growing. LÄS MER

  7. 20. Infrared Photodetectors based on InSb and InAs Nanostructures via Heterogeneous Integration-Rapid Melt Growth and Template Assisted Selective Epitaxy

    Författare :Heera Menon; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rapid Melt Growth RMG ; Template Assisted Selective Epitaxy TASE ; InSb; InAs; infrared detectors; nBn detector; photoconductor; nanostructures; nanowires;

    Sammanfattning : Monolithic heterogeneous integration of III-V semiconductors with the contemporary Si Complementary Metal Oxide Semiconductor (CMOS) technology has instigated a wide range of possibilities and functionalities in the semiconductor industry, in the field of digital circuits, optical sensors, light emitters, and high-frequency communication devices. However, the integration of III-V semiconductors is not trivial due to the differences in lattice parameters, polarity, and thermal expansion coefficient. LÄS MER
