During millions of years of evolution, all creatures have found their ways of harvesting, storing and utilizing the energy coming from the sun. Plants use photosynthesis to convert carbon dioxide to glucose. With a low efficiency of only 3%, plants still c ...
The number of studies on solid state ionic thin films (Nanoionics) has increased dramatically over last decades due to their high potential in micro and nanoscale technologies. Micro solid oxide fuel cells (micro-SOFC), and resistive switching memories (Re ...
Solid Oxide Fuel Cells (SOFCs) have gathered considerable attention as a clean, highly efficient conversion device for the production of both electricity and heat from fuels. Due to their high operating temperatures, SOFCs do not require pure hydrogen as f ...
Lifetime and durability issues connected with Solid Oxide Fuel Cell (SOFC) technology are strongly related to the amount of contaminants that reach the stack. In this study the focus is on organic silicon compounds (siloxanes) and their highly detrimental ...
Some fundamental challenges are shaping the world we live in, and the need for alternative materials and energies is one of the most prominent issues of this century, especially in the light of global warming and energy need. Another crucial point concerns ...
The Pt-supported hollow structured Pt-HZrO2 with the shell thickness of 27 nm is successfully synthesized. The water retention ability of Pt-HZrO2 is significantly enhanced compared with that of SiO2@ZrO2 due to the hydrophilic hollow structured HZrO2 with ...
Three Ta-based compds. were successfully prepd. using a simple chem. synthesis. In dye-sensitized solar cell systems Ta3N5, TaOx, and Ta4C3 acted as counter electrode catalysts and demonstrated impressive catalytic activity and stability for I3- redn. The ...
The surface morphology of MnSi thin films grown on Si(111)-7 x 7 substrates was investigated by systematically changing the amount of deposited Mn. A new 3 x 3 surface reconstruction was found at the very initial growth stages, whose atomic configuration w ...
Miniaturized, low temperature Solid Oxide Fuel Cells (SOFCs) that operate below 600 °C are promising for supplying electrical power to portable devices. Thin electrolyte membranes of less than one micrometer thickness have been shown to yield reasonable po ...
