The method and app. for carrying out electrochem. promoted catalytic reactions, i.e., catalytic reactions where the catalytic rate and selectivity is modified by applying an elec. current or potential between the porous catalyst film which is deposited on ...
Future nuclear power plants like the very high temperature reactor or the gas cooled fast reactor need materials able to comply with extreme operating conditions (temperature, cooling gas, radiation). Advanced materials like oxide dispersion strengthened ( ...
This paper presents a methodology for the optimal design and operation of man-portable power generation devices based on fuel cells. To illustrate the methodology, we focus on a simple process that consists of a fuel processing reactor, a solid-oxide fuel ...
The elimination of aromatic compounds present in surface water by photo-Fenton with sunlight as the source of radiation was studied. The concentrations of Fe3+ and H2O2 are key factors for this process. A solar simulator and a prototype parabolic collector ...
Oxide dispersed strengthened (ODS) ferritic-martensitic steels are investigated as possible structural material for the future generation of High Temperature Gas Cooled Nuclear Reactors. The Ni based austenitic ODS superalloys are not considered, because o ...
Nuclear materials have been successfully employed in commercial fission reactors for many decades. Research and material development for advanced fission system and future thermo-nuclear fusion reactors have acquired maturity while great challenges remain ...
Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...
The catalytic filters of sintered metal fibers (SMF) coated by thin MFI-type zeolite (silicalite-1, ZSM-5) films have been synthesized and tested in the reactor with structured catalytic bed. The catalysts show multifunctional behavior, combining catalysis ...
The gas lift pump concept based on the bubbling of an inert gas into the primary reactor coolant to enhance natural circulation is currently considered in a number of PbBi-cooled reactor concepts. Thus, the analysis of available void fraction data and the ...
A novel composite material based on carbon nanofibers (CNF) grown on sintered metal fibers (SMFInconel) filter was investigated for its favorable properties as catalytic support. The CNF were formed directly over the SMFInconel by thermal (650 degrees C) c ...
