  1. 1. Residual Products in the Steel Industry Used for Briquetting

    University essay from KTH/Materialvetenskap

    Author : Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
    Keywords : ;

    Abstract : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. READ MORE

  3. 2. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

    Abstract : Torv är idag i många sammanhang klassad som ett fossilt bränsle och utdikade torvmarker släpper ut koldioxid. Även lämpligheten med att i samma utsträckning som idag fortsätta använda torv i odlingssammanhang ifrågasätts. READ MORE

  5. 4. Apparent density for water atomized low-carbon steel powder

    University essay from KTH/Materialvetenskap

    Author : Simon Lindström; [2023]
    Keywords : ;

    Abstract : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. READ MORE
