  1. 1. Characterization of the cobalt content in zinc ore from Zinkgruvan, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ingeborg Hjorth; [2022]
    Keywords : Zinkgruvan; Bergslagen; Cobalt; Sphalerite; Pyrrhotite; Safflorite;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. READ MORE

  2. 2. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  3. 3. Interaction between cobalt nanoparticles and DPPC at pulmonary conditions

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Paula Sommer; [2021]
    Keywords : metallic nanoparticles; lipids; lung surfactants; adsorption; pulmonary fluid; metalliska nanopartiklar; lipider; lungtensider; adsorption; syntetisk lungvätska;

    Abstract : Nanomaterial produceras och används alltmer i tekniska lösningar för att förbättra t.ex. materialegenskaper. Eftersom ett materials egenskaper förändras när det är i nanoskala så påverkas även dess toxikologiska egenskaper. READ MORE
