  1. 1. Functional Textile Coatings Containing Flake-shaped Fillers investigations on selected optical and electrical properties

    University dissertation from Borås : Högskolan i Borås

    Author : Veronica Malm; Högskolan i Borås.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flakes; fillers; textile coating; properties; multilayered mica; effect pigment; angle-dependent colour change; metals; conductivity; resistance measurements; e-textiles; flexibility; durability; Textil och mode generell ; Textiles and Fashion General ;

    Abstract : This thesis investigates the manufacturing and characterisation of functionalised textile coatings containing different types of flake-shaped fillers with angle-dependent colour-changing and electrically conductive properties, respectively. Common benefits of these types of flakes are their high aspect ratio, which offers low filler loading with high functional performance. READ MORE

  2. 2. Transmission Electron Microscopy of Graphene and Hydrated Biomaterial Nanostructures Novel Techniques and Analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sultan Akhtar; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene flakes; magnetic beads DNA coils; hydrated biomaterials; transmission electron microscopy; focused ion beam scanning electron microscopy; bright-field dark-field imaging; high resolution imaging; electron diffraction and cryogenic temperatures; Materialvetenskap; Materials Science;

    Abstract : Transmission Electron Microscopy (TEM) on light element materials and soft matters is problematic due to electron irradiation damage and low contrast. In this doctoral thesis techniques were developed to address some of those issues and successfully characterize these materials at high resolution. READ MORE

  3. 3. Inhibition of Aluminium Pigments for Waterborne Coatings

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Philip Karlsson; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen evolution; AFM; surfactant; aluminium pigment; polymer; silica stabilisation; water based; adsorption; inhibition; waterborne; printing ink; QCM-D; AAS; reflectometry; encapsulation; paint; metallic pigment; coating; XPS;

    Abstract : Micrometer-sized aluminium flakes for use as pigments in waterborne coatings need protection, since the reaction between aluminium and water causes formation of aluminium hydroxide and hydrogen gas. The aluminium hydroxide destroys the metallic appearance of the pigment flakes and the evolution of hydrogen gas leads to a dangerous pressure build-up in the paint containers. READ MORE

  4. 4. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jie Zhao; Uppsala universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE

  5. 5. Glycaemic Response in Relation to Gastric Emptying and Satiety in Health and Disease

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Joanna Hlebowicz; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes; Cinnamon; Satiety; Healthy subjects; Gastroparesis; Blood Glucose; Ultrasound; Gastric emptying; Whole-kernel; Dietary fibre; Beta-glucan; Wheat; Oat;

    Abstract : Dietary fibre and whole grains are recommended to prevent the development of type 2 diabetes. Low glycaemic index foods that are rich in fibre are recommended to control blood glucose levels. Gastric emptying, together with other factors, regulate the postprandial blood glucose response.
