  2. 1. NEW OLIGOTHIOPHENES

    Author : Fredrik von Kieseritzky; KTH; []
    Keywords : oligothiophenes; synthesis; light-emitting diodes; field-effect transistors; photoluminescence; quantum efficiency;

    Abstract : This thesis deals with synthesis and characterization of newoligothiophenes and derivatives thereof, for use as organicsemiconductors in optical and electronic applications, such asfield-effect transistors and light-emitting diodes. Much workis devoted to the development of new synthetic strategies forinteresting building blocks, to beused for synthesizing suchmaterials. READ MORE

  4. 2. New Oligothiophenes

    Author : Fredrik von Kieseritzky; KTH; []
    Keywords : ;

    Abstract : This thesis deals with synthesis and characterization of newoligothiophenes and derivatives thereof, for use insemiconductor applications. One series of regiodefinedoligothiophenes up to the octamer was prepared and evaluated.Photoluminescence quantum efficiencies in solution were 22-31%, but dropped to 2-5 % in the solid state.

  5. 3. New technology - new jobs? : The case of mobile telecommunications in Sweden

    Author : Esa Manninen; Charles Edquist; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technological Change; Product Innovation; Process Innovation; Employment Effects; Job Creation; Job Destruction; Labour Productivity; Mobile Telecommunications; Telekommunikationsteori; Mobiltelefoni; Teknikutveckling; Produktutveckling; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This is a study about employment effects of technological change. The concept of employment effects here refers to changes in number of employees in economic activities as a result of technological change. Technological change, in turn, refers to product innovation and process innovation. READ MORE

  6. 4. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

  7. 5. New professionals and new technologies in new higher education? : Conceptualising struggles in the field

    Author : Alison Hudson; Per-Olof Erixon; Gaby Weiner; Miriam David; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Higher education; technologies; technology; change; new professionals; academic practice.; Pedgogical work; Pedagogiskt arbete; pedagogik; Education;

    Abstract : This thesis explores the practices and positionings of two groupings of professionals in UK higher education, ‘educational developers’ and ‘learning technologists’. It investigates the emergence of the groupings, and their professional paths and respective approaches to supporting teaching and learning. READ MORE
