Highly dispersed ruthenium catalysts can be prepared on alumina by aqueous impregnation of ruthenium. EXAFS at the K-edge showed that this type of catalyst, after calcination and reduction, consisted of ruthenium particles, which were about 0.8 nm in

Fossil power plant high-energy piping systems operated at high temperatures are subject to creep damage, which is a time-dependent phenomenon. Traditional guidelines, such as the American Society of Mechanical Engineers (ASME) B31.1 Power Piping Code

High-angle annular dark-field or Z-contrast microscopy was used to demonstrate that well dispersed metal supported catalysts consist of nanometer sized clusters. Depending upon the impregnated metal, different cluster sizes were observed. Grouping of

Over the past few years, our understanding of the evolution of limbs has been improved by important new discoveries in the fossil record. Additionally, rapid progress has been made in identifying the molecular basis of vertebrate limb development. It

The biological consequences of ectopic FGF-4 expression were examined in chimaeric mouse embryos prepared with ES cells constitutively expressing FGF-4. The embryos exhibit abnormalities of the limbs and the anterior central nervous system. The limb
