  1. 21. Structural controls and associated alterations in the West Maurliden volcanic-hosted massive sulfide deposit, Skellefte district, northern Sweden

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

    Author : Nikolay Zhivkov; [2021]
    Keywords : West Maurliden; volcanic-hosted massive sulfide deposit; Skellefte district; Structure;

    Abstract : Volcanic-hosted massive sulfide (VMS) deposits are one of the main sources for zinc, copper, lead, silver and gold in Sweden. The majority of VMS deposits in Sweden are located in the Bergslagen region and the Skellefte district (Fig. 1). READ MORE

  3. 22. Graphene Quantum Dots as Fluorescent and Passivation Agents for Multimodal Bioimaging

    University essay from KTH/Tillämpad fysik

    Author : Nüzhet Inci Kilic; [2021]
    Keywords : graphene quantum dots; hybrid nanoparticles; x-ray fluorescence contrast agents; multimodal bioimaging; grafen-kvantprickar; hybrida nanopartiklarna; multimodal bioavbildning; röntgenfluorescens kontrastmedel;

    Abstract : Zero-dimensional graphene (carbon) quantum dots have been drawing attention in bio-related applications since their discovery, especially for their optical properties, chemical stability, and easily modifiable surface.  This thesis focuses on the green synthesis of nitrogen-doped graphene quantum dots (GQDs) for dual-mode bioimaging with X-ray fluorescence (XRF) and optical fluorescence.

    Keywords : Vanadium; Malmberget; Kiruna Type;

    Abstract : The Norrbotten region is an important Swedish mining district with occurrence of several economic deposits and sub-economic deposits of apatite iron ores (Kiruna Type) and epigenetic Cu-Au ores. The apatite iron ores include the large Malmberget deposit mined by LKAB company as one of their world class underground mines. READ MORE

  5. 24. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    University essay from Umeå universitet/Kemiska institutionen

    Author : Björn Sundqvist; [2021]
    Keywords : ;

    Abstract : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.

  6. 25. Assessing a Modeling Standard in Volcanic-Geothermal Systems: the Effects of the Lower System Boundary

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Shelly Mardhia Faizy; [2021]
    Keywords : Geothermal; Numerical Modelling; Laccolith; Permeability; Topography;

    Abstract : Geothermal energy consumption is projected to increase along with other renewable energy in the future. Therefore, it is important to have a better understanding on the evolution of geothermal systems to optimize the exploitation of such resources. Generally, numerical models are used as a fundamental tool to study a potential geothermal field. READ MORE
