  1. 1. Surface and porous structure of pigment coatings : Interactions with flexographic ink and effects on print quality

    Author : Erik Bohlin; Caisa Johansson; Per Edström; Göran Ström; Karlstads universitet; []
    Keywords : Coating; Pigment; Calendering; Porosity; Flexographic Printing; Print quality; Chemical Engineering; Kemiteknik;

    Abstract : Each day, we are confronted with a large amount of more or less important information that we have to consider, and even in our digital society we need paper for communication, documentation and education. Much of the paper we use or are confronted by in our daily life, such as newspapers, books and packages, contains printed images or texts, and the appearance of both the print and the supporting surface is important.

  2. 2. Targeting the prostate tumor microenvironment and vasculature : the role of castration, tumor-associated macrophages and pigment epithelium-derived factor

    Author : Sofia Halin; Anders Bergh; Pernilla Wikström; Stina Rudolfsson; Carl-Henrik Heldin; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; angiogenesis; castration therapy; microenvironment; stroma; tumor-associated macrophages; pigment epithelium-derived factor; PEDF; vasculature; Pathology; Patologi; patologi; Pathology;

    Abstract : BACKGROUND: Prostate cancer is the most common cancer among Swedish men. For patients with metastatic prostate cancer the standard therapy is castration, a treatment that initially provides symptomatic relief but unfortunately is not curative. New therapeutic targets for advanced prostate cancer are therefore needed. READ MORE

  3. 3. Inhibition of Aluminium Pigments for Waterborne Coatings

    Author : Philip Karlsson; Chalmers University of Technology; []
    Keywords : 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. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Author : Mikael Karlsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE

  5. 5. Use of Switchable Carbamate Surfactants for Design of Reversible Colouring of Cotton

    Author : Anna-Karin Hellström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cotton; pigment; textile colouring; de-colouring; switchable surfactant; carbamate;

    Abstract : Circularity of materials is a global need. However, recycling of cotton often requires many steps involving chemical or mechanical treatments. According to the waste hierarchy, reuse is a more environmentally benign approach than recycling, giving extended lifecycles with only limited processing of materials. READ MORE
