    Abstract : The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants.

  5. 13. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents

    Author : Pierre Oesterle; Stina Jansson; Jerker Fick; Ulrika Rova; Capucine Dupont; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Activated biochars; HTC; regeneration; analytical chemistry; adsorption; degradation; nontarget analysis; wastewater; circular economy; emerging contaminants; surface chemistry; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap; Pharmaceutics; galenisk farmaci; analytisk materialfysik; analytical material physics; Analytical Pharmaceutical Chemistry; analytisk farmaceutisk kemi;

    Abstract : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. READ MORE

  6. 14. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    Author : Pauline Vandoolaeghe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Abstract : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. READ MORE

  7. 15. Polysaccharide thin film studies - Adsorption of oxidized xylan on cellulose

    Author : Chonnipa Palasingh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface plasmon resonance; solubility; macromolecule adsorption; quartz crystal microbalance with dissipation monitoring;

    Abstract : Wood xylans are renewable natural materials that have potential for future use in bio-based products. However, their high price and low production capacity restrict their industrial use and current applications. This research aimed to explore the potential of wood xylans for film applications.
