  2. 1. Structure evolution of phase-separated EC/HPC films for controlled drug release

    Author : Pierre Carmona; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electron microscopy; coarsening; cellulose; phase separation kinetics; drug delivery; phase separation mechanisms; porous film; biopolymer; controlled drug release; confocal laser scanning microscope; spin-coating.;

    Abstract : Porous phase-separated ethylcellulose/hydroxypropylcellulose (EC/HPC) films are used to control drug transport out of pharmaceutical pellets. The drug transport rate is determined by the structure of the porous films that are formed as the water-soluble HPC leaches out. READ MORE

  4. 2. Preparation and Properties of Surface Modified Thin Polymer Films

    Author : Sofia Kihlman Øiseth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aminodextran; plasma polymerisation; polymer films; high-density polyethylene HDPE ; UV ozone treatment; surface modification; glow discharge plasma; in situ control; spin coating;

    Abstract : This thesis deals with preparation, modification and characterisation of thin polymer films. Most of the work has been performed using thin films of high-density polyethylene (HDPE) as a model system for systematic surface modifications by glow discharge plasma and UV/ozone treatments.

    Abstract : Specific molecular recognition materials are important in analytical applications. It has been a longstanding dream for scientific explorers to realise a versatile method to generate materials that can recognize biological and chemical substance of interests. READ MORE

  6. 4. Focused Ion Beam Preparation and Transmission Electron Microscopy of Materials for Energy Applications

    Author : Filip Lenrick; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy; focused ion beam; solid oxide materials; fuel cell; semiconductor materials; nanowire; LED; solar cell;

    Abstract : Throughout this thesis, samples of various materials with applications in energy converting devices have been prepared by focused ion beam machining and investigated by transmission electron microscopy. Energy converting devices can be solar cells or light emitting diodes, which turn light into electricity or vice versa. READ MORE

  7. 5. Synthesis of well arrayed structures with assistance of statistical experimental design

    Author : Yajuan Cheng; Pär Jösson; Zhe Zhao; Gunnar Westin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; experimental design; statistical analysis; monolayer arrays of silica spheres; vertically aligned ZnO rod arrays; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : During the synthesis of well arrayed nano/micro structures through wet chemical methods, plenty of parameters are usually involved. Consequently, it is extremely time- and cost-consuming to find out the optimized synthesis conditions by using the conventional "changing one separate factor at a time" (COST) strategy. READ MORE
