    Abstract : Recovery and reuse of materials is important for a circular economy. In recent years the recovery of critical metals from end-of-life products has received increased attention. Various streams, e.g. READ MORE

  4. 27. Theoretical Studies on Artificial Water Splitting-Water Oxidation and Proton Transfer

    Author : Ying Wang; Hans Ågren; James Gardner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The present thesis is concerned with the theoretical studies on artificial water splitting process. As the quick development of research on utilizing of solar energy, which is a green, clean, and renewable energy source, many research groups focus their attention on artificial photo-synthesis systems inspired by the photosystem I and II.

  5. 28. Investigating Hydrogenous Behavior of Zintl Phases : Interstitial Hydrides, Polyanionic Hydrides, Complex Hydrides, Oxidative Decomposition

    Author : Verina Kranak; Ulrich Häussermann; Gordon Miller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zintl phases; Hydrogenous Zintl phases; Polyanionic Zintl phases; Interstitial Zintl phases; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is an investigation into the hydrogenous behavior of Zintl phases. Zintl phases are comprised of an active metal (i.e alkali, alkaline earth, and rare earth) and a p-block element. The discussion gives an overview of the influence hydrogen affects the electronic and geometric structure of Zintl phases and subsequent properties. READ MORE
