    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER

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

    Författare :Erik Bohlin; Caisa Johansson; Per Edström; Göran Ström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating; Pigment; Calendering; Porosity; Flexographic Printing; Print quality; Chemical Engineering; Kemiteknik;

    Sammanfattning : 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.

  4. 8. Structure-Performance Relations of Oxygen Barriers for Food Packaging

    Författare :Åsa Nyflött; Magnus Lestelius; Ellen Moons; Lars Järnström; Carlsson Kvarnlöf Gunilla; Chris Bonnerup; José Maria Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Barrier coating; Permeability; Dynamic Mass Transport; Modelling; Diffusion; Polymer; Dispersion; Kaolin; LCA; Starch; Hemicellulose; Materials Science; Materialvetenskap;

    Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER

  5. 9. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame-retardant; cellulose fibre; cellulose nanfibril; layer-by-layer technique; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.

  7. 10. Phosphorylated Cellulose Nanofibrils : A Nano-Tool for Preparing Cellulose-Based Flame-Retardant Materials

    Författare :Maryam Ghanadpour; Lars Wågberg; Jeffrey W. Gilman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorylated cellulose nanofibrils; flame-retardant; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The growing awareness of the need for a circular society and a circular chemistry has spurred the interest in using wood-based cellulose as a raw material for the preparation of new macroscopic devices and construction materials. The interest has been particularly focused on cellulose nanofibrils (CNF), which has led to the development of new material concepts through a nanoscale bottom-up engineering using renewable CNF.
