The rate of ejection of alpha-recoil thorium-234 into solution from the surface of zircon sand gives an alpha-recoil range of 550 angstroms. The alpha-recoil thorium-234 atoms ejected into the groundwater may supply excess uranium-234. In pelagic sediments, ejected alpha-recoil thorium-234 may contribute to the supply of mobile uranium-234 in the sedimentary column.
One of the major advantages SOFCs is their high fuel flexibility. Next to natural gas and hydrogen, which are today's most common fuels for SOFC-systems cell-/stack-testing respectively, various other applicable as well. In literature, a number promising results show that available propane, butane, ammonia, gasoline, diesel etc. can be applied. Here, performance an anode supported cell operated...

Introduction The purpose of this project is to develop new understanding of the atomic-scale structure and dynamics of oxide ion conducting ceramic materials that are at the heart of solid oxide fuel cells (“SOFC’s”), with the aim of more effectively optimizing their performance, lowering operating temperatures, size, and costs. Given the high efficiencies of fuel cells and their likely central...
Protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (SOFCs). Inthis study a layer of manganese was coated on the surface of AISI 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. The oxidation beha...
One of the six selected concepts to be part Generation IV nuclear reactors is Supercritical Light Water Cooled Reactor. The High-Performance Reactor (HPLWR) European version and it a very promising design. In recent years, interest in study thorium-based fuel cycles has been renewed its possibilities for current LWRs have evaluated. use fuels will fundamental future sustainability energy, since...
The lunar meteorite Sayh al Uhaymir 169 consists of an impact melt breccia extremely enriched with potassium, rare earth elements, and phosphorus [thorium, 32.7 parts per million (ppm); uranium, 8.6 ppm; potassium oxide, 0.54 weight percent], and adherent regolith. The isotope systematics of the meteorite record four lunar impact events at 3909 +/- 13 million years ago (Ma), approximately 2800 ...
