6. Influence of mass transport on glycerol electrooxidation on palladium in alkaline media
Master-uppsats, KTH/Tillämpad elektrokemiSammanfattning : Vid produktion av biodiesel produceras även råglycerol (10 vikt%) som biprodukt och utbudet av råglycerol har ökat över de senaste åren till följd av att biodieselproduktionen ökat. Marknadsvärdet för råglycerol är lågt, men det är en utmärkt föregångare till att producera mervärdesprodukter för exempelvis läkemedelsindustrin, kemikalieindustrin eller kosmetika. LÄS MER
7. Prospective Life Cycle Assessment of an Electrochemical Hydrogenation Process Over a Nickel Foam Cathode
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The need for a safe and sustainable chemical industry has called for the development of emerging technologies with improved environmental performance. In this study, an emerging electrochemical hydrogenation process over Ni foam is being developed at the laboratory scale with an expectation of less environmental impacts than a conventional palladium on carbon hydrogenation process.

8. Laptops and smartphones - a gold mine? : A material flow analysis of small electronics in a Swedish organisation with focus on metal resources
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : The aim of this study is to contribute to today´s knowledge about stocks of electronic products on the organisational level. This is done by using a bottom-up MFA on laptops and smartphones in a chosen organisation, the data collected for this study is done by both semi-structured interviews and literature searches.

9. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknikSammanfattning : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. LÄS MER
10. Oxygen Reduction Catalysts in Alkaline Electrolyte
Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Alkaline fuel cells are a promising technology, with their sturdy design and many applications they are held back mostly by their cost. By introducing a catalyst, the activation energy of the cell can be reduced to an overcomable amount. LÄS MER
