  1. 1. A geological investigation on bedrock suitability for mineral carbonation conducted in the south central part of Sweden

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

    Author : Edvard Pearson; [2023]
    Keywords : Mineral carbonation; geological investigation; Åsensbruk; Falun; Grums; Öje; Skutskär;

    Abstract : Increasing global temperatures due to anthropogenic emissions of greenhouse gases is one of our times most dire and urgent challenges to overcome if we are to achieve a sustainable healthy planet. The primary way of accomplishing this is by reducing the amount of released greenhouse gases. READ MORE

  3. 2. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    University essay from Uppsala universitet/Strukturkemi

    Author : Ismail Yussuf Hassan; [2023]
    Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  4. 3. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    University essay from Lunds universitet/Kemiska institutionen

    Author : David Llorens Rauret; [2022]
    Keywords : Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Abstract : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. READ MORE

  5. 4. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Sjö; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  6. 5. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Erina Prastyani; [2022]
    Keywords : EBSD; SEM; shocked quartz; quartz; CPO; seismic velocity; anisotropy; Chicxulub; impact crater; pole figures; MTEX toolbox; microstructural features; planar deformation feature; planar fracture; feather features;

    Abstract : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. READ MORE
