  1. 11. Metal Films for Printed Electronics : Ink-substrate Interactions and Sintering

    Författare :Thomas Öhlund; Håkan Olin; Hans-Erik Nilsson; Mattias Andersson; Patrick Gane; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inkjet printing; silver nanoparticles; paper; flexible substrates; sintering; printed electronics; IPL sintering; flash sintering; copper films; coatings; thin films; AgNP; conductive films; metal films;

    Sammanfattning : A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. LÄS MER

  3. 12. Additive manufacturing methods and materials for electrokinetic systems

    Författare :Katarina Bengtsson; Nathaniel D Robinson; Leif Nyholm; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fabrication of miniaturized devices is usually time-consuming, costly, and the materials commonly used limit the structures that are possible to create. The techniques most often used to make microsystems involve multiple steps, where each step takes considerable time, and if only a few systems are to be made, the price per device becomes excessive.

  4. 13. Synthesis and Characterization of Carbon Based One-Dimensional Structures : Tuning Physical and Chemical Properties

    Författare :HamidReza Barzegar; Thomas Wågberg; Hans Kuzmany; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon Nanotube; single-walled carbon nanotube; nitrogen doped; chemical vapor deposition; fullerene; hybrid structures; nanomaterials; nanomaterial;

    Sammanfattning : Carbon nanostructures have been extensively used in different applications; ranging from electronic and optoelectronic devices to energy conversion. The interest stems from the fact that covalently bonded carbon atoms can form a wide variety of structures with zero-, one- and two-dimensional configuration with different physical properties.

  5. 14. Electronic Properties of Nanotubes

    Författare :Alex Kleiner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with various aspects of the electronic properties of carbon nanotubes and of generic nanotubes in magnetic fields. Carbon nanotubes are highly symmetric objects on the nanometer scale which show an interesting interplay of their geometry with electronic properties. LÄS MER

  7. 15. Dynamical properties of metal halide and oxyhydride perovskites

    Författare :Rasmus Lavén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; perovskite; quasielastic neutron scattering; phonon; inelastic neutron scattering; diffusion; oxyhydride; hydrogen dynamics; Metal halide perovskite; hydride ion.;

    Sammanfattning : This thesis concerns investigations on the dynamical properties of two classes of energy-relevant materials, namely metal halide and oxyhydride perovskites, using neutron scattering techniques. These two classes of materials share the same aspect of a perovskite-type crystal structure but are different in terms of their functional properties and concomitant promise for various technological applications.
