  2. 1. A study of devices and materials for polymer based LEDs

    Author : Jonas Birgerson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjugated; polymer; XPS; LED; Magnesium; blend; copolymer;

    Abstract : Since the discovery that it is possible to dope conjugated polymers into high electrical conductivity the research in the field of conjugated polymers has increased a lot. Much of the research activity has been concentrated to the design and fabrication of light emitting devices. READ MORE

  4. 2. The influence of Morphology on the Transport and Mechanical Properties of Polyethylene

    Author : Bereket Neway; KTH; []
    Keywords : n-hexane diffusion; polyethylene; free volume; solubility; sorption; desorption; mechanical properties; orientation; thermal properties; blend;

    Abstract : The sorption/desorption behaviour of n-hexane in high molarmass linear polyethylene (PE) and branched PEs with 0.39 and5.09 hexyl branches per 100 main chain C atoms andcrystallinities between 4 and 82% at 298 K has been studied.Crystal core contents determined by Raman spectroscopy werealways lower than those determined by density measurements.

  5. 3. Studies in Swedish Sign Language : Reference, Real Space Blending, and Interpretation

    Author : Anna-Lena Nilsson; Brita Bergman; Terry Janzen; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Swedish Sign Language; INDEX-c; first person pronoun; non-dominant hand; buoys; Real Space blending; token blend; surrogate blend; signing space; constructed dialogue; constructed action; sign language interpreting; Sign language; Teckenspråk; Sign Language; teckenspråk;

    Abstract : This thesis comprises four separate studies of the same material: a ten-minute Swedish Sign Language monologue. Study I describes the form, meaning, and use of the sign INDEX-c, a pointing toward the chest traditionally described as a first person pronoun. READ MORE

  6. 4. Engaged in a seamless blend : A study on how academic staff approach connections to professional practice and research in the engineering curriculum

    Author : Marie Magnell; Lars Geschwind; Anette Kolmos; Jussi Välimaa; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Engineering education; research-teaching links; professional practice; teaching and learning regimes; Technology and Learning; Teknik och lärande;

    Abstract : The connection between research and teaching is one of the main attributes of higher education. Aside from this link, the relation between higher education and the world of work is another prevailing facet, particularly in education for the professions. READ MORE

  7. 5. The morphology of polyfluorene : fullerene blend films for photovoltaic applications

    Author : Ana Sofia Anselmo; Håkan Rensmo; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science; Organic Photovoltaics; Polymer Solar Cells; Materialteknik; Materials Engineering;

    Abstract : Polymer photovoltaic systems whose photoactive layer is a blend of a semiconducting polymer with a fullerene derivative in a bulk heterojunction configuration are amongst the most successful organic photovoltaic devices nowadays. The three-dimensional organization in these layers (the morphology) plays a crucial role in the performance of the devices. READ MORE
