  1. 1. Multifunctional Nanocellulose Composite Materials

    Författare :Olof Eskilson; Daniel Aili; Robert Selegård; Erik Martinsson; Aji Mathew; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanomaterials; nanocomposites; bacterial cellulose; wound care; plasmonics; catalysis;

    Sammanfattning : Nanoparticles (NPs) are particles with more than one dimension between 1 and 100 nm. Because of their small size, they typically display different physical and chemical properties than the corresponding bulk materials. NPs have been used in many different applications, such as in electronics, optics, catalysis, and in biomedicine. LÄS MER

  3. 2. Bacterial adhesion to polyelectrolyte modified materials based on nanocellulose

    Författare :Jonatan Henschen; Lars Wågberg; Per Larsson; Josefin Larsson; Aji Mathew; Michael Malkoch; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bacterial adhesion; cellulose nanofibrils; polymer adsorption; polyvinylamine; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Since the introduction of materials based on cellulose nanofibrils (CNFs), these materials have been studied extensively and are suggested to be suitable for use in, for example, hygiene and health care products. A property not very well studied but that could further increase the usability of CNF products is the possibility of controlling bacterial adhesion to the materials. LÄS MER

  4. 3. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

    Författare :Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. LÄS MER

    Sammanfattning : In about 2:10,000 births the external part of the ear, the auricle, is severely malformed or absent. Furthermore, tumors and trauma can cause defects to the auricle. LÄS MER

  7. 5. Exploring cellulose as a biomacromolecule for enhanced battery metal ion recovery/recycling

    Författare :Billy W. Hoogendoorn; Richard Olsson; Yuanyuan Li; Mikael S. Hedenqvist; Aji Mathew; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomacromolecules; Nanocellulose; metal oxide nanoparticle synthesis; electrodeposition; battery recycling; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The research focused on the effects of integrating nanocellulose in the solidification of metal ions into metal oxide particles or metallic electrodeposits.  Firstly, the cellulose was isolated as highly crystalline ca. 15-25 nm thick and 500 nm long fibers from bacterial cellulose using acid hydrolysis and had a negative surface charge.
