    Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

  3. 2. Dendrite suppression during electrodeposition on lithium metal through molecular level design

    Master-uppsats, KTH/Kemi

    Författare :Lukas Lekberg; [2022]
    Nyckelord :Dendrite; Density functional theory; Solid lithium battery;

    Sammanfattning : Här undersöks en strategi som behandlar dendrittillväxt på en solid litiumanod i ett litiumbatteri. Med hjälp av täthetfunktionalsteori adsorberades fyra flytande kristaller på litiumytan vilket ledde till en gränsskiktsstabilisering. Denna stabilisering har i en tidigare rapport länkats till dendrittillväxt i en fasfältsmodell. LÄS MER

  4. 3. Coupled flux nucleation model applied to the metallic glass AMZ4

    Master-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mattias Tidefelt; [2021]
    Nyckelord :Material science; numerical modeling; metallic glasses; classical nucleation theory;

    Sammanfattning : Additive manufacturing (AM), also known as 3D-printing, has made it possible to produce components made of bulk metallic glass (BMG) which have remarkable properties compared to parts made of conventional alloys. A metallic glass is a metastable noncrystalline alloy that form if a melt is quenched with a sufficient cooling rate. LÄS MER

  5. 4. Method for interfacial energy determination of gold nanoparticles on solid surfaces

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Mikaela Petersson; [2020]
    Nyckelord :Nanoparticles; sintering; interfacial energies; Young s equation; contact angle; Au; Si; silica; Sapphire; Al2O3; SEM; AFM; TEM; FFT; Science General;

    Sammanfattning : The high surface-to-volume ratio of nanoparticles (NPs) makes them an interesting source for scientific research. How interfacial energies interplay between such a small structure and a solid bulk surface, are important because of the versatile applications NPs regard. LÄS MER
