Nanopore Patterned Pt Array Electrodes for Triple Phase Boundary Study in Low Temperature SOFC
This paper describes the fabrication and investigation of morphologically stable model electrode structures with well-defined and sharp platinum/yttria-stabilized zirconia YSZ interfaces to study geometric effects at triple phase boundaries TPBs . A nanosphere patterning technique using monodispersed silica nanoparticles, which are applied to the YSZ surface by the Langmuir– Blodgett method, is...
متن کاملCatalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application.
Catalyst layers (4-20 microm) of rhodium (1 wt%) supported on alumina, titania, and ceria-zirconia (Ce(0.5)Zr(0.5)O(2)) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water. Catalytic performances were studied for low-temperature (< or = 500 degrees C) steam reforming of propane at a steam to carbon ratio equal to 3 and l...
متن کاملLow-temperature sterilization and new technologies.
The new low-temperature sterilization technologies are presented as an alternative to the use of ethylene oxide. This review was performed in order to identify evidences of the antimicrobial activity, toxicity, adverse events and the applicability of these technologies. The research was carried through the electronic databases MEDLINE and LILACS up to 2005. The authors analyzed 10 articles in t...
متن کاملGreen Method for Synthesizing Gallium Nitride Nanostructures at Low Temperature
Gallium nitride (GaN) nanostructures (NS) were synthesized using pulseddirect current plasma enhanced chemical vapor deposition (PDC-PECVD) on quartzsubstrate at low temperature (600°C). Gallium metal (Ga) and nitrogen (N) plasma wereused as precursors. The morphology and structure of the grown GaN NS werecharacterized by field emission scanning electron microscope (FE-SEM), transmissionelectro...
متن کاملTemperature gradients in microelectrode measurements: Relevance and solutions for studies of SOFC electrode materials
a r t i c l e i n f o Microelectrodes on solid electrolytes, contacted by current-collecting tips, have become increasingly important for analyzing electrochemical properties of electrode materials in solid state ionics. Samples are usually asymmetrically heated from the bottom side. It is shown experimentally, e.g. by thermovoltage measurements, impedance spectroscopy and infrared camera pictu...
