  1. 1. Organic electronic switch devices

    Författare :Fredrik Jakobsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER

  3. 2. Intramolecular electron transfer in DNA and ruthenium(II) systems

    Författare :Johan Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solvent relaxation; light switch effect; dppz; electron transfer and hydrogen bond;

    Sammanfattning : When ruthenium(II) complexes with heteroaromatic ligands absorb light, an electron is pushed from the metal ion out into one of the ligands, a process called metal-to-ligand-charge-transfer (MLCT). The resulting excited state can be used to initiate further electron transfer processes, or it can decay relatively slow back into the ground state with the emission of light. LÄS MER

  4. 3. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Författare :Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Sammanfattning : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. LÄS MER

  7. 5. Treatment with the monoclonal antibody rituximab in Multiple Sclerosis : a study based on an academic clinical trial

    Författare :Pierre de Flon; Anders Svenningsson; Martin Gunnarsson; Katarina Laurell; Sten Fredrikson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Multiple sclerosis; Rituximab; Cytokines; Immunological profile; Neurofilament light; Treatment satisfaction; neurologi; Neurology;

    Sammanfattning : Background: Multiple sclerosis (MS) is a chronic, inflammatory disease, affecting the central nervous system. A growing number of disease modifying treatment alternatives entails a need for an individualised risk-benefit- convenience analysis in the counselling of patients and methods to monitor the treatment effect, including markers for subclinical inflammation.
