  1. 1. Development of a microfluidic device to study simultaneous crystallization in the LIBs recycling process

    Master-uppsats, KTH/Kemiteknik

    Författare :Shefali Paresh Solanki; [2023]
    Nyckelord :Battery recycling; microfluidics; simultaneous crystallization; simulation; crystal technology; microfluidics experimental setup; Batteriåtervinning; mikrofluidik; simultan kristallisering; simulering; kristallteknologi; mikrofluidikexperimentuppställning;

    Sammanfattning : Återvinning av litiumjonbatterier (LIB) är avgörande på grund av kritiska råmaterialreserver och miljöhänsyn vid kassering. Hydrometallurgisk LIB-återvinning, en framstående industriell teknik, står inför kostnadseffektivitets- och komplexitetsutmaningar. LÄS MER

  3. 2. Monte Carlo study of disorder in electronic tight-binding models

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Carl Pettersson; [2023]
    Nyckelord :Monte Carlo; Tight-binding model; Falicov-Kimball model; Physics and Astronomy;

    Sammanfattning : Oftentimes solids are described by uniform, periodic lattices. In reality, however, there is often some disorder on some of the sites in the lattice. This disorder may come from, for example, there being a different type of atom or tightly bound electrons resulting in a larger on-site potential, affecting the electronic properties of the lattice.

  4. 3. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Mikael Granberg; [2022]
    Nyckelord :PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Sammanfattning : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

  5. 4. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Grunditz Jakob; [2022]
    Nyckelord :Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

    Sammanfattning : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. LÄS MER

  7. 5. Technical Feasibility of an Intensified Absorption Process for Bioenergy Carbon Capture and Storage (BECCS)

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Alva Sarby; Edvin Ljungquist; Ville Loman; [2022]
    Nyckelord :Carbon capture; Carbon dioxide; Potassium bicarbonate; Potassium carbonate; Crystallization;

    Sammanfattning : This project aims to evaluate the technical feasibility of an absorption process for carbon capture and storage (CCS). Currently, the CCS process commonly used in the industry is energy and cost-intensive, making its large-scale development a difficult task. LÄS MER
