  2. 1. Exploring cellulose as a biomacromolecule for enhanced battery metal ion recovery/recycling

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

    Abstract : 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.

  7. 5. Characterization of Electrodeposited Fe-based Metallic Coatings: Toward a Sustainable Approach

    Author : Antonio Mulone; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrodeposition; structural characterization; coatings; electrodeposited tin; iron alloys;

    Abstract : Electrodeposition has rapidly grown in the last 50 years and it has been applied to deposit metals and alloys with complex shapes or to produce fully dense nanostructures and amorphous coatings. Thanks to the achieved improved properties of the electrodeposited materials, electrodeposition has been applied in a wide set of applications including protective coatings, and magnetic and electronic applications.
