  1. 1. Carbon nanotubes and graphene polymer composites for opto-electronic applications

    Författare :Nicolas Boulanger; David Barbero; Christian Müller; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; polythiophene; electrical conductivity; crystallography; graphene; nanoimprint lithography; synchrotron diffraction; fysik; Physics;

    Sammanfattning : Carbon nanotubes are carbon based structures with outstanding electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer in the form of composites, in order to affect the electronic behavior of the matrix material. LÄS MER

  2. 2. Structure and morphology control of organic semiconductors for functional optoelectronic applications

    Författare :Jenny Enevold; Ludvig Edman; Thomas Wågberg; Christian Müller; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; organic photonics; patterning; fullerene; polymerization; dimerization; spray-deposition; morphology; small molecule donor; high open-circuit voltage;

    Sammanfattning : The functionality and application of organic semiconductors are largely dependent on their constituent structure and morphology. This thesis presents a number of functional and novel approaches for the control and tuning of structural and morphological features of a variety of organic semiconductor materials, and also demonstrates that these approaches can be utilized for improved device operation of field-effect transistors, organic solar cells and light-emitting electrochemical cells.

  3. 3. Bridging McMurry and Wittig in One-Pot : Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes

    Författare :Juri Mai; Sascha Ott; Christian Müller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonyl olefination; reductive aldehyde coupling; stereoselective; organophosphorus; phosphaalkene; phosphanylphosphonate; Wittig; Horner-Wittig; Horner-Wadsworth-Emmons; McMurry; Kemi; Chemistry;

    Sammanfattning : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.

  4. 4. Svenska sjöofficerare under 1500-talet

    Författare :Ingvar Sjöblom; Mats Hallenberg; Leos Müller; Jan Samuelson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Military History; Naval History; Early modern history; Naval Officer; Organisation; Leadership; War Science; War history; Swedish Navy; Competence; Power Relations; Naval tactics; 16th Century; Gentry; Militärhistoria; marinhistoria; krigsvetenskap; ledarskap; organisation; sjöofficer; 1500-tal; marintaktik; adel; frälse; flottan; sjöofficerskåren; History; historia; Krigsvetenskap;

    Sammanfattning : What was the expertise of a naval officer during the 16th century? How did the naval officers’ expand, and what was the power relations like? These questions asked initially in the dissertation, try to capture the essence of the actual purpose, namely to investigate the development, power relations and the competence of a naval officer in the Swedish Navy during the 16th century (1522-1595).There was a correlated relationship between the military strategic choice of the operational area, naval tactical choices vessel types for customized naval warfare and the need for naval officers.

  5. 5. Upper middle Cambrian through Furongian of Scandinavia with focus on trilobites, paleoenvironments and correlations

    Författare :Fredrik Terfelt; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleontologi; Palaeontology; Scandinavia; Paleoenvironments; Biostratigraphy; Trilobites; Cambrian; Furongian;

    Sammanfattning : This thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. LÄS MER
