  1. 1. Development of a porous material from cellulose nanofibrils

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Hedda Törneman; [2021]
    Nyckelord :CNF; cellulose nanofibrils; xerogels; aerogels; cross-linking; porous materials; polymers;

    Sammanfattning : Cellulose nanofibrils are a biobased and renewable material with potential to be used in many different applications. Such applications include air filtration, absorption of liquids, and thermal insulation.  To be used for these applications the cellulose nanofibrils must form a porous and dry material. LÄS MER

    Författare :Erik Rozenbeek; [2020]
    Nyckelord :;

    Sammanfattning : The nickel-rich cathode material Li[Ni0.8Mn0.1Co0.1]O2 is a much sought after material in Li-ion batteries for the future of electric vehicles due to its high specific capacity. LÄS MER

  3. 3. Biocarbon production from biomass based energy plant forapplication in high-value materials

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :David Söderberg; [2019]
    Nyckelord :;

    Sammanfattning : Natural graphite, a type of carbon, is used in most battery driven electronic devices around the world as it serves as the anode in Li-ion batteries. Since 67\% of global production of graphite originates from a single country the EU has classified it as a critical raw material with a high supply risk. LÄS MER

  4. 4. Evaluation of alternative methods forquality control of Tungsten Carbide : An evaluation of four different particle measuring techniques

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Markus Näsman; [2019]
    Nyckelord :Particle measurement; Quality control; Tungsten Carbide; Hard metal; Fisher Sub-Sieve Sizer; Brunauer Emmett Teller; X-ray Diffraction; Laser Diffraction;

    Sammanfattning : The purpose of this study was to evaluate four different measuring methods as potentialquality control tests for Tungsten Carbide (WC) raw material used in the hard metalmanufacturing at Seco Tools Fagersta. This was warranted as the current quality testcalled the HcK test, is very time consuming and the results provided that are used formilling time calculations cannot be relied on. LÄS MER

  5. 5. Fe-Mo-oxide of spinel structure for methanol oxidation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maria Thulin; [2016]
    Nyckelord :iron molybdate catalyst; methanol oxidation; Fe-Mo-oxide; spinel structure; formaldehyde catalyst; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The aim of this master thesis was to investigate a Fe-Mo-oxide catalyst of spinel structure for methanol oxidation to produce formaldehyde and determine if the spinel could be an alternative to the commercial Formox catalyst used today. This included firstly, synthesising the catalyst to get more knowledge of the formation of the structure and secondly, determine the activity, selectivity to formaldehyde and stability of the catalyst.
