  1. 1. Electrocatalytic properties of Ni hydroxides with Zn or Co in the Ni matrix

    Författare :Gert Göransson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Redoxmediated prcesses; pulse plated NiZn; carbon paste electrodes; RRDE; DEMS; XAFS; DEMS;

    Sammanfattning : The majority of the work in this thesis has been made with the improvement of the systems for electrochemical co-generation of chemicals and electricity in mind. This is an appealing but challenging way of producing chemicals with energy as a bi-product, and is commonly referred to as “green chemistry”. LÄS MER

  3. 2. Study of particle-current-electrocrystallization interactions in electroplating of Ni/SiC coatings

    Författare :Santiago Pinate; Caterina Zanella; Peter Leisner; Jönköping University; []
