  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. Surface characterization and force measurements applied to industrial materials with atomic force microscopy

    Författare :Illia Dobryden; Aji P. Mathew; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik; Experimental physics; Experimentell fysik;

    Sammanfattning : The thesis focuses on the application of force measurements with atomic force microscopy (AFM) on materials with a few surface contacts/asperities and chemically modified surfaces. The technique allows measurements of ultra-small intermolecular and surface forces, down to the piconewton level. LÄS MER

  4. 3. 3D printing of Green Water Purification Filters : Design towards Sustainable and Scalable Biocomposite Materials

    Författare :Natalia Fijoł; Aji P. Mathew; Lennart Bergström; Alexander Bismarck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D printing; water treatment; polylactic acid; nanocellulose; nanochitin; hydroxyapatite; green metal-organic frameworks; materialkemi; Materials Chemistry;

    Sammanfattning : The globally escalating water pollution and water scarcity necessitates the development of efficient and sustainable water treatment technologies. This thesis investigates the feasibility of utilizing renewable and waste materials in the form of green composites for the fabrication of water purification filters via Fused Deposition Modelling (FDM).
