Effects of Alloyed and Oxide Phases on Methanol Oxidation of Pt-Ru/C Nanocatalysts of the Same Particle Size
(Amer Chemical Soc, 2009-05-14)
In this work, methanol oxidation was studied on carbon-supported Pt-Ru nanocatalysts, where the amounts of alloyed and oxide phases were modified by heat treatments in different atmospheres. Because particle growth was ...
Generalised single-equation load flow method for unbalanced distribution systems
(Inst Engineering Technology-iet, 2011-03-01)
This study presents a generalised single-equation load flow (GSELF) method for the analysis of unbalanced distribution systems. The proposed method is derived from a recently formulation published in the technical literature, ...
