  1. 1. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Cecilia Zambelli; [2023]
    Keywords : ;

    Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  3. 2. A model for heterogenic catalytic conversion of carbon dioxide to methanol

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Elin Johannesson; [2020]
    Keywords : Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

    Abstract : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.

  4. 3. Medical Implant Applications of Mesoporous Silica Films

    University essay from Linköpings universitet/Nanostrukturerade material

    Author : Patrik Geite; [2019]
    Keywords : Mesoporous silica; films; implants; drug delivery; osseointegration;

    Abstract : A literature review of medical implant applications of mesoporous silica films was written, highlighting the advantages and limitations of different film synthesis methods. Both films synthesized through the EISA sol-gel method and particulate films, including those synthesized through the direct growth method, were reviewed and discussed. READ MORE

  5. 4. Antibody-conjugated Gold Nanoparticles integrated in a fluorescence based Biochip

    University essay from Institutionen för fysik, kemi och biologi

    Author : Jonas Ljungblad; [2009]
    Keywords : Gold nanoparticles; Bioconjugation; Metal enhanced fluorescence; Localized Surface Plasmon Resonance; Ultra Violet Visible spectroscopy; Atomic Force Microscopy; Transmission Electron Microscope; Scanning Electron Microscope;

    Abstract : Gold nanoparticles exhibit remarkable optical properties and could prove useful in sensitive biosensing applications. Upon illumination gold nanoparticles produce localized surface plasmons, which influence nearby fluorophores and an enhancement in their fluorescence intensity can be observed. READ MORE
