  2. 6. Anionic Graft Copolymers with Poly(ethylene oxide) Side-Chains; Synthesis, Solution Properties and Ion Conduction

    Author : Helene Dérand; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dieletric properites; ion conduction; solution properties; aggregation; amphiphilic polymers; poly ethylene oxide ; preparation; grafting; Polymer technology; biopolymers; Polymerteknik;

    Abstract : The research underlaying this thesis involves synthesis and characterization of well-defined anionic graft copolymers carrying poly(ethylene oxide) (PEO) side-chains. Two different grafting techniques were used. Backbone polymers were prepared through radical terpolymerization of maleic anhydride, styrene and an additional comonomer. READ MORE

  4. 7. Dose Plan Optimization in HDR Brachytherapy using Penalties : Properties and Extensions

    Author : Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Göran Sporre; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : High dose-rate (HDR) brachytherapy is a specific type of radiotherapy used to treat tumours of for example the cervix, prostate, and breasts. In HDR brachytherapy applicators are implanted into or close to the tumour volume. A radioactive source is moved through these applicators and stops at certain positions, known as dwell points.

  5. 8. Solution Chemistry and Morphological Properties for Organic Solar Cells : Exploring Alternative Solvents Using Microgravity and Modelling as Tools

    Author : Ishita Jalan; Jan van Stam; Patricia Saenz Mendez; Stela Andrea Muntean; Mariano Campoy-Quiles; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solution chemistry; green solvents; microgravity; OPV; HSP; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Abstract : Organic photovoltaics (OPVs) have the advantage of the accessibility of energy for all, due to facile and low-cost processing, with its low energy payback time compared to other technologies, therefore promising applications. Research and development have led to power conversion efficiencies of nearly 20% and now catching up to their inorganic counterparts. READ MORE

  6. 9. Generic Properties of Polymer Solutions

    Author : Takashi Uematsu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE

  7. 10. Pharmaceutical cocrystals : formation mechanisms, solubility behaviour and solid-state properties

    Author : Amjad Alhalaweh; Peter York; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crystal engineering; cocrystal; formation; solubility; pH; dissolution; surface properties; solid-state properties; Health Science; Hälsovetenskap;

    Abstract : The primary aim of pharmaceutical materials engineering is the successful formulation and process development of pharmaceutical products. The diversity of solid forms available offers attractive opportunities for tailoring material properties. READ MORE
