1. 21. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

   Författare :Johanna Löberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

   Sammanfattning : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. LÄS MER

3. 22. Electrochemical characterization of LiNi1/3Mn1/3Co1/3O2 at different stages of lifetime

   Författare :Maria Varini; Göran Lindbergh; Marca Doeff; KTH; []
   Nyckelord :Li-ion battery; positive electrode; LiNi1 3Mn1 3Co1 3O2; electrochemical characterization; ageing; semi-empirical model; Chemical Engineering; Kemiteknik;

   Sammanfattning : Li-ion batteries have entered our everyday life first as power sources for small electronics, and recently for electric vehicles and stationary storage applications. As the requirements on the performance and lifetime of Li-ion batteries increase and diversify, it becomes paramount to properly understand their electrochemical performance at single-electrode level, and their evolution over cycling.

4. 23. Study of Electrochemical Behaviour and Corrosion Resistance of Materials for Pacemaker Lead Applications

   Författare :Andreas Örnberg; Jinshan Pan; Jukka Lausmaa; Ann Cornell; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-base alloy; 35N LT; MP35N; Ta; TiN coating; electrochemical behaviour; corrosion resistance; Chemistry; Kemi;

   Sammanfattning : For patients suffering bradycardia, i.e., too slow heart rhythm, the common treatment is having a pacemaker implanted. The pacemaker system consists of the pacemaker and a pacing lead. LÄS MER

5. 24. (Nano)materials for electrochemical sensing applications in different fields

   Författare :Nasrin Razmi; Omer Nur; Magnus Willander; Frank Bier; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochemical bio sensors; Nanomaterials; AuNSs; α-Fe2O3 ZnO nanocomposite; RuO2-Nf pH electrodes; MIP technology;

   Sammanfattning : Health care and the medical industry, environmental monitoring and food sector are just a few examples of human’s major concerns. Design and analytical applications of (bio)sensors and sensing (nano)materials in these fields which have drawn tremendous attention by scientific community, require multidisciplinary knowledge in materials, transducers, and measurement methodologies.

7. 25. Applications for Molten Carbonate Fuel Cells

   Författare :Ivan Rexed; Göran Lindbergh; Carina Lagergren; Michel Cassir; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell MCFC ; poisoning; electrolyte degradation; SO2; Electrochemical Impedance Spectroscopy EIS ; CO2 separation; button cell set-up; reversible molten carbonate fuel cell; high temperature electrolysis.; Chemical Engineering; Kemiteknik;

   Sammanfattning : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. LÄS MER
