  1. 11. Metal ion adsorption of highly mesoporous magnesium carbonate

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Rebecka Löfgren; [2019]
    Keywords : nanomaterial; water treatment; adsorption; metal removal; ion exchange; porous materials;

    Abstract : In this project the adsorption ability of mesoporous magnesium carbonate (MMC) for copper (Cu), cobalt (Co), chromium (Cr) and arsenic (As) was evaluated. This was done by mixing MMC and dissolved metal (of different concentrations) and measuring the concentration of the solution before and after addition of MMC with Inductively coupled plasma optical emission spectroscopy.

  3. 12. Novel Hybrid Nanomaterials : Combining Mesoporous Magnesium Carbonate with Metal-Organic Frameworks

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Viktor Sanderyd; [2018]
    Keywords : Nanomaterials; Metal-Organic Frameworks; MOF; MMC; Porous; Mesoporous; Upsalite; Hybrid materials; Core-shell;

    Abstract : Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. READ MORE

  4. 13. Point source carbon capture by porous inorganic carbonates

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Jonas Hultberg; [2018]
    Keywords : Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Abstract : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  5. 14. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Jonatan Fast; [2017]
    Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  6. 15. Heavy metal removal and water treatment using Upsalite

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Philip Erenbo; [2017]
    Keywords : Upsalite; lead; cadmium; nickel; MgO3; heavy metal; water treatment;

    Abstract : Ion exchange reactions between Upsalite, a mesoporous magnesium carbonate, and metal ions of cadmium, lead and nickel have been studied to evaluate the capacities of Upsalite as a water treatment agent. Uptake capacity and reaction kinetics have been evaluated using a batch experiment and atomic absorption spectroscopy. READ MORE
