  2. 31. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

    Author : Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

    Abstract : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. READ MORE

  4. 32. Biodegradable nanocomposite films based on amylopectin and chitosan

    Author : David Nordqvist; Mikael Hedenqvist; Lars Berglund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : The use of disposable material is rapidly increasing, today the absolute majority of the material used for these application, i.e. food packages, are oil-based plastics such as polyethylene and polypropylene. Therefore it is of great importance to find alternative biodegradable materials made from renewable resources for this huge growing market. READ MORE

  5. 33. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

    Author : Evelina Brännvall; Britt-Marie Steenari; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. READ MORE

  6. 34. Wood Nanotechnologies for Transparency, Fire Retardancy and Liquid Separation

    Author : Qiliang Fu; Lars Berglund; Hiroyuki Yano; KTH; []
    Keywords : Teknisk materialvetenskap; Materials Science and Engineering; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : In this thesis, wood nanotechnologies for transparent, fire-retardant and hydrophobic/lipophilic wood have been developed. There are two main parts; wood template preparation/processing concepts and materials design using these templates.In the wood template processing part, highly porous nanostructured wood templates are prepared.

  7. 35. Wood hydrolysate Barriers

    Author : Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

    Abstract : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. READ MORE
