  1. 1. Design and Fabrication of Light-Emitting Electrochemical Cells

    Författare :Andreas Sandström; Ludvig Edman; Ronald Österbacka; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light-emitting electrochemical cell; fabrication; organic semiconductors; organic electronics; ambient fabrication; roll-to-roll; fysik; Physics;

    Sammanfattning : Glödlampan, en gång symbolen för mänsklig uppfinningsförmåga, är idag på väg att försvinna. Lysdioder och lågenergilampor har istället tagit över då dessa har betydligt längre livstid och högre effektivitet. LÄS MER

  3. 2. Deliberating Intractability : Exploring Prospects of Deliberative Democracy in Intractable Natural Resource Management Conflicts

    Författare :Andreas Johansson; Karin Beland Lindahl; Annica Sandström; Hendrik Wagenaar; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Deliberative democracy; Democracy; Natural resource management; Intractable conflicts; Deliberation; Mining; Mining conflicts; Interpretive analysis; Political Science; Statsvetenskap;

    Sammanfattning : The increasing prevalence of intractable conflicts over natural resources, which defy technocratic solutions, highlights an urgent need for states, managers, and practitioners to find democratic methods for addressing them. In the normative debate over the optimal approach to managing these conflicts, deliberative democracy has emerged as a leading theoretical framework, sparking a deliberative turn in both political theory and natural resource governance.

  4. 3. Fast Microwave-Enhanced Intra-, Pseudo-intra- and Intermolecular Heck Reactions

    Författare :Andreas Svennebring; Mats Larhed; Anja Sandström; Erik Van der Eycken; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; palladium; Heck reaction; chelation control; microwave; Farmaceutisk kemi;

    Sammanfattning : The Heck reaction is one of the most appreciated methods for carbon-carbon bond formation. Due to its mildness and ability to be tuned by additives, it often leaves few alternative competitive reactions. It has also proven easy to develop the reaction conditions in an environmentally benign direction. LÄS MER

  5. 4. High frequency scattering and spectral methods

    Författare :Imad Akeab; Sven-Erik Sandström; Andreas Asheim; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waves; Signals and Systems; Vågor; signaler och system;

    Sammanfattning : This thesis consists of five parts. The first part is an introduction with references to some recent work on 2D electromagnetic scattering problems at high frequencies. It also presents the basic integral equation types for impenetrable objects and the standard elements of the method of moments. LÄS MER

  7. 5. Solution-processed light-emitting electrochemical cells : challenges and opportunities

    Författare :Etienne Auroux; Ludvig Edman; Christian Larsen; Andreas Sandström; Magnus Berggren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light-emitting electrochemical cell; PEDOT:PSS; Photonics; Ion transfer; Solution-based fabrication; Electronics; elektronik; Materials Science; materialvetenskap; jonfysik; Ion Physics;

    Sammanfattning : Our world is filling up with electronics. High-tech gadgets are integrated everywhere, from smart fridges able to track expiry dates and food usage, to microchip implants that let us unlock doors and pay with our hands. LÄS MER
