Membranes have been used for gas separation for quite some time but have seen major growth during the 90’s [1]. For many industrial applications involving gas streams, it is important that membranes resist high temperatures and corrosive environments. As in Table 1, organic membranes are not heat resistant at high temperatures while zeolite membranes have pore sizes too large to separate gases ...

Parkinson's disease (PD) is one of the most common neurodegenerative diseases affecting an increasing number of people worldwide with the aging society. Although the etiology of PD remains largely unknown, it is now clear that genetic factors contribute to the pathogenesis of the disease. Recently, several causative genes have been identified in mendelian forms of PD. Growing evidence indicates...

for Session – 3 Hydrogen from Coal The Influence of Copper Concentration on the Permeability of Pd-Cu Alloy Membranes Bryan D. Morreale, Bret H. Howard US Department of Energy, National Energy Technology Laboratory PO Box 10940, Pittsburgh, PA 15236 Abstract Hydrogen membranes have been identified as a promising technology for extracting pure hydrogen from processes such as coal gasification, h...

Pd-Cu alloys are of particular interest for use as hydrogen purification membranes, and identifying the effects stoichiometry on permeability is key to exploring possibility improving this material. In study, we carried out permeation tests Pd-51.5 mol?Cu alloy in order understand excess Cu atoms with B2-type crystal structure. Even though contained a small amount face-centered cubic phase, its...
