2. 1. Electrochemical Deposition of Nanostructured Metal/Metal-Oxide Coatings

   Author : Jonas Eskhult; Leif Nyholm; Jan-Otto Carlsson; Jay Switzer; Uppsala universitet; []
   Keywords : Inorganic chemistry; electrochemical deposition; local pH; Cu2O; Sb2O3; complex; EQCM; reduction; Oorganisk kemi;

   Abstract : Electrochemical deposition finds applications in the electronics- and protective coating industries. The technique is a versatile tool for the synthesis of alloys and thin films. Knowledge of the fundamental aspects of the electrode processes enables the design of nanostructured materials. READ MORE

4. 2. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

   Author : Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

   Abstract : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. READ MORE

5. 3. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

   Author : Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

   Abstract : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. READ MORE

6. 4. Electrode Degradation in Polymer Electrolyte Fuel Cells

   Author : Linnéa Strandberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalyst degradation; Platinum stability; Fuel cells;

   Abstract : To mitigate the climate crisis, and reduce carbon emissions from e.g. the transport and energy sectors, hydrogen has been proposed to be used as an environmentally friendly alternative energy carrier. READ MORE

7. 5. Towards quinone/pEDOT conducting redox polymers as energy storage materials

   Author : Huan Wang; Martin Sjödin; Xavier Crispin; Uppsala universitet; []
