Altering the Equilibrium Condition in Sr-Doped Lanthanum Manganite

Description: The material of choice for a solid oxide fuel cell cathode based on a yttria-stabilized zirconia (YSZ) electrolyte is doped lanthanum manganite, (La, Sr)MnO{sub 3}. It excels at many of the attributes necessary for a system to work at the required operating temperature and is flexible enough to allow for materials optimization. Although strontium-doping increases the electronic conductivity of the material, the ionic conductivity of the material remains negligible under operating conditions. St… more

Final Technical Report for the Period October 1, 1996 - September 30, 1998

Description: The body of this report is contained in two appendicies that deal with time-resolved spectroscopic analysis of microballoon implosions. The first paper introduces the experimental observation of plasma-induced line shifts in recent implosion experiments together with our theoretical analysis. These observations provide a new parameter with which to diagnose very dense laser-produced plasmas. It also indicates that at even higher densities shift-effects can be expected to be more prominent. The … more
