  1. 1. Utveckla design på maskinprototyp som utvinner expanderad grafit på Pegil Innovations AB

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Ellen Weberg; Susanna Österlund; [2021]
    Nyckelord :;

    Sammanfattning : Grafen är ett material som växer i popularitet och erkännande och anses ha lika stor potential att förändra världens produktion, om vetenskapen lyckas, som plasten hade. Pegil innovations AB har i samarbete med 2D fab tagit fram en maskinprototyp som expanderar grafitpulver med hjälp av mikrovågsteknik. LÄS MER

  3. 2. Multifunctional Wood Polymer Composites Reinforced with Graphene Nanoplatelets : Investigating if multifunctionality can be achieved in wood polymer composites through the addition of graphene nanoplatelets

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Vanessa Meulenberg; [2019]
    Nyckelord :Wood polymer composites; graphene; multifunctional; wood flour;

    Sammanfattning : Graphene nanoplatelets (GNPs) were used to reinforce wood polymer composites (WPCs) in order to achieve multifunctionality. Multifunctionality could be achieved through the GNPs because of their excellent mechanical and electrical properties. The research consists of two parts: HDPE/GNP/WF composites and LLDPE/GNP composites. LÄS MER

  5. 4. Electron Assisted Growth of h-BN on Gr/Ir(111)

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Virginia Boix De La Cruz; [2018]
    Nyckelord :Two-dimension materials; 2D; Graphene; hexagonal Boron Nitride; Growth; CVD; STM; XPS; Physics and Astronomy;

    Sammanfattning : Stacked heterostructures of two-dimensional (2D) materials are emerging as promising building blocks for a wide range of applications. These devices, which range from tunneling transistors to light-emitting diodes, use the properties of 2D materials that are not accessible by their bulk counterparts. LÄS MER

  7. 5. Characterization of epitaxial graphene grown on silicon carbide

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Författare :Anton Jansson; [2014]
    Nyckelord :Graphene; epitaxial graphene; silicon carbide; SiC; 4H-SiC; 6H-SiC; sublimation; graphene manufacturing; AFM; atomic force microscopy; tapping mode; surface study; stepheight; charactarization;

    Sammanfattning : In this thesis work several manufacturing methods for graphene is discussed followed by an indepth study of graphene grown by a high temperature sublimation method (sublimation of siliconcarbide). The graphene surfaces studied have been grown by Graphensic AB, both graphenegrown on the Si-face and the C-face of the silicon carbide were studied. LÄS MER
