738 Journal of Chemical Education • Vol. 81 No. 5 May 2004 • www.JCE.DivCHED.org The investigation of the nature of living organisms has been dominated recently by the study of the genome. The main thrust has been to obtain and interpret linear sequences of DNA (or RNA) nucleotides, but it is clear that an understanding of activity in cells can only come from the further, now quantitative, anal...

A nonmetal doping strategy was exploited for the conventional La0.5Sr0.5FeO3-δ (LSF) cathode, allowing high performance proton-conducting solid oxide fuel cells (H-SOFCs). Unlike previous studies focusing on utilization of metal oxides as dopants, phosphorus, which is a element, used cation dopant LSF by partially replacing Fe ions to form new La0.5Sr0.5Fe0.9P0.1O3-δ (LSFP) compound. The H-SOFC...
