  1. 6. Acoustic Platform for MXene Synthesis and Electrochemical Behaviour of i-MXenes in Aqueous Electrolytes

    Författare :Ahmed El Ghazaly; Johanna Rosén; Ahmed Etman; Husam N. Alshareef; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface Acoustic Waves; MXene; i-MXene; Supercapacitor;

    Sammanfattning : Climate Change is believed to be the greatest global challenge and on its forefront is the topic of energy. While being of extreme importance, debates over energy have become a normality. LÄS MER

  3. 7. Novel electrode and photoelectrode materials for hydrogen production based on molecular catalysts

    Författare :Andrew J. Bagnall; Leif Hammarström; Vincent Artero; Sascha Ott; Alexander Cowan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical mechanism; hydrogen; artificial photosynthesis; molecular catalyst; hydrogen evolution; cobalt; Kemi; Chemistry;

    Sammanfattning : The PhD project focussed on the application of a cobalt tetraazamacrocyclic complex, in the literature commonly referred to as [Co(CR)Cl2]+ as a molecular catalyst for the hydrogen evolution reaction (HER). This was within the broader scope of the EU MSCA H2020 ITN ‘eSCALED’ project, which primarily aimed to create artificial leaf devices for the storage of solar energy in chemical fuels and, as part of this, sought the development of novel bio-inspired and scalable materials.

  4. 8. Mathematical modelling and experimental simulation of chlorate and chlor-alkali cells

    Författare :Philip Byrne; KTH; []
    Nyckelord :chlorate; chlor-alkali; current density distribution; current distribution; potential distribution; hydrodynamic behaviour; electrolysis; bubble-evolution;

    Sammanfattning : The production of chlorate, chlorine and sodium hydroxiderelies heavily on electrical energy, so that savings in thisarea are always a pertinent issue. This can be brought aboutthrough increased mass transfer of reacting species to therespective electrodes, and through increased catalytic activityand uniformity of current density distribution at theseelectrodes.

  5. 9. Electrochemical and ion transport characterisation of a nanoporous carbon derived from SiC

    Författare :Marcelo Zuleta; Pehr Björnbom; Derek Pletcher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Cottrell equation; radial diffusion; chronoamperometry; potential step measurements; microelectrode technique; nanoporous carbon; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : In this doctoral project, a relatively new form of carbon material, with unique narrow pore size distribution around 7 Å and with uniform structure, has been electrochemically characterised using the single particle microelectrode technique. The carbon has been used as electrode material for supercapacitors. LÄS MER

  7. 10. On the behaviour of the lithium ion battery in the HEV application

    Författare :Ragna Elger; KTH; []
    Nyckelord :lithium ion battery; hybrid electric vehicle;

    Sammanfattning : The lithium ion battery is today mainly used in cell phonesand laptops. In the future, this kind of battery might beuseful in hybrid electric vehicles as well. LÄS MER
