  2. 1. Rheology and UV-curing of a star-branched polyester

    Author : Hans Claesson; KTH; []
    Keywords : Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Abstract : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.

  4. 2. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Author : Anna Finne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

    Abstract : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. READ MORE

  5. 3. Development of an Improved Thermal-Hydraulic Modeling of the Jules Horowitz Reactor

    Author : Reijo Pegonen; Henryk Anglart; Yann Bartosiewicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jules Horowitz Reactor; CATHARE2; STAR-CCM ; FLICA4; Material Testing Reactor; Computational Fluid Dynamics; System code; Reactor modeling;

    Abstract : The newest European high performance material testing reactor, the Jules Horowitz Reactor, is under construction at CEA Cadarache research center in France. The reactor will support existing and future nuclear reactor technologies, with the first criticality expected at the end of this decade. READ MORE

  6. 4. Performance Studies and Star Tracking for PoGOLite

    Author : Cecilia Marini Bettolo; Mark Pearce; Nicolas Produit; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polarization; pulsars; x-ray; PoGOLite; Astroparticle physics; Astropartikelfysik;

    Abstract : PoGOLite is a balloon-borne experiment, which will study polarized soft γ-ray emissionfrom astrophysical targets in the 25-80 keV energy range by applying well-typephoswich detector technology. Polarized γ-rays are expected from a wide variety of sources including rotation-powered pulsars, accreting black holes and neutron stars,and jet-dominated active galaxies. READ MORE

  7. 5. Crystallisation of star polyesters with poly (ε-caprolactone) arms : approaching the problem of early stages in polymer crystallisation

    Author : Eugenia Núñez; KTH; []
    Keywords : Technology; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The knowledge regarding early stages in polymer crystallisation remains inconclusive due to experimental limitations. The reason is that the initially formed polymer crystals rearrange rapidly at the crystallisation temperature. Faster experimental techniques or simulation would be suitable alternatives to approach the problem. READ MORE
