  1. 1. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization

    Författare :Eugenia Núñez; Ulf W. Gedde; Bernard Lotz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystallization; Constrained structures; poly ε–caprolactone ; poly ethylene oxybenzoate .; Polymer chemistry; Polymerkemi;

    Sammanfattning : The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. LÄS MER

  3. 2. Antimicrobial Polymer Composites for Medical Applications

    Författare :Peter Kaali; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; medical polymers; antimicrobial; body fluids; degradation; Polymer chemistry; Polymerkemi;

    Sammanfattning : The current study and discuss the long-term properties of biomedical polymers in vitro and invivo and presents means to design and manufacture antimicrobial composites. Antimicrobialcomposites with reduced tendency for biofilm formation should lead to lower risk for medicaldevice associated infection. LÄS MER

  4. 3. Biomolecule Trapping With Stimuli-Responsive Polymer Coated Nanostructures

    Författare :Justas Svirelis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomolecule transportation; protein interaction; polymer brushes; quartz crystal microbalance with dissipation monitoring; fluorescence microscopy; Poly N-Isopropylacrylamide ; surface plasmon resonance; poly ethylene glycol ;

    Sammanfattning : Trapping biomolecules in nanosized gaps is of great interest in novel systems for single molecule analysis and membranes, which filter biomolecules. Current platforms are lacking in full functionality to facilitate biomolecule trapping and transport in their native environment and without covalent tethering to surfaces. LÄS MER

  5. 4. System-in-a-Package on Low-Cost Liquid Crystal Polymer Substrate

    Författare :Gang Zou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FDTD; integrated passive components; ACA; liquid crystal polymer; FEM; flip-chip; RF; anisotropic conductive adhesive; system-in-a-package; system-on-a-package;

    Sammanfattning : System-in-a-Package (SiP) is one of the most advanced approaches to meet the requirements for future high-density electronics packaging. In this thesis, a 3D system-in-a-package concept with embedded active and passive components is proposed, where a liquid crystal polymer (LCP) was used as the base substrate. LÄS MER

  7. 5. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER
