  1. 1. Catalytic Graphitization of Biomass : For the Production of Graphite Materials

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Daniel Andersson; André Brunnberg; Emil Lind; [2021]
    Nyckelord :;

    Sammanfattning : In recent years the material graphite has been heavily studied since its use in widespread applications have increased, for example batteries, vehicles, and solar cells. When the need for this type of material increases the efficiency and the sustainability of the production methods must be taken into consideration. LÄS MER

  3. 2. Impact of Converter Modulation Strategies on the Losses in a Traction Motor

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

    Författare :Emil Fjällström; [2015]
    Nyckelord :Induction Machine; FEM; FLUX; Induktionsmotor; FEM; FLUX;

    Sammanfattning : With an increased demand on high-efficiency electrical machines in traction applications, better understanding in the losses induced by the converter is needed. The harmonic losses from the converter are non-negligible part of the total losses in an induction machine, and these harmonic losses have been studied here with a focus on iron, skin-effect and proximity losses.

  4. 3. En studie av ett grundvattensystem - Geologiska Institutionens provpumpningsanläggning på P7 i Revingehed

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Emil Engvall; [2015]
    Nyckelord :akvifär; grundvattensystem; grundvattenföroreningar; Revingehed; provpumpningsanläggning; Earth and Environmental Sciences;

    Sammanfattning : In this study, I have examined a groundwater system located close to a military training camp in Revingehed outside Lund, Sweden. The study includes water analyses of substances in two of three aquifers. The study also shows the effects on the groundwater system when a well located in the third aquifer was pumped with 100 l/min during 3 days. LÄS MER

  5. 4. Development of an in vitro assay for analysis of cellular uptake of nanoparticles

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Lina Olsson; [2013]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Abstract MRI, magnetic resonance imaging, is used for disease detection such as assessing blood flow, detecting tumours and diagnosing many forms of cancer. Contrast agents are chemical substances that increase the MRI sensitivity. One class of contrast agents are the so called nanoparticulate contrast agents. LÄS MER

  7. 5. Potentiell fosforfrigörelse från sedimentet i Bornsjön, sydvästra Stockholm : The potential leakage of phosphorus from sediment in Lake Bornsjön, south western Stockholm

    Magister-uppsats, Institutionen för livsvetenskaper

    Författare :Susanne Lindhe; [2007]
    Nyckelord :;

    Sammanfattning : Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. LÄS MER
