1. 1. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

   Författare :Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

   Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.

3. 2. On the Development of Mucin-based Biomaterial Coatings

   Författare :Tomas Sandberg; Karin Caldwell; Jan Carlsson; Thomas Arnebrant; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucin; Biomaterial; Surface-exposed protein; XPS; Neutrophil; Cell morphology; SEM; QCM-D; Viscoelasticity; Protein-stabilization; HNL; Coating; MG1; BSM; PGM; SEC-MALS-RI; Mucin quantification; Protein adsorption; Ellipsometry; Biomaterials; Biomaterial;

   Sammanfattning : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. LÄS MER

4. 3. Preparation and characterization of nanocellulose films and coatings from industrial bio-residues

   Författare :Martha Herrera; Per Stenius; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Sammanfattning : The aim of this work has been to study cellulose nanocrystals (CNC) from bio-residues and their use as green coating materials. In the first part of this work, physical and chemical properties of different types of cellulose nanocrystals, from different raw material sources and different treatments were compared. LÄS MER

5. 4. Biomimetic Deposition of Hydroxyapatite on Titanium Implant Materials

   Författare :Carl Lindahl; Håkan Engqvist; Martin Andersson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialvetenskap; Materials Science;

   Sammanfattning : The clinical success of a bone-anchored implant is controlled by many factors such as implant shape, chemical composition, mechanical and surface properties. The surface properties (e.g. LÄS MER

7. 5. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy

   Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER
