We investigated the oxygen reduction reaction (ORR) mechanism on Pt nanoparticles (NPs) dispersed on several carbon blacks with various physicochemical properties ( i.e. specific surface ranging from 80 to 900 m 2 g -1 , different graphitization degree, etc .). Using the kinetic isotope effect (KIE) along with various electrochemical characterizations, we determined that the rate determining step (RDS) of the ORR is a proton-independent step when the density of Pt NPs on the surface of the carbon support is high. Upon decrease of the de

As childhood death is considered nonnormative and outside of the life course, children may be memorialized differently than adults who have had an opportunity for fuller lives. As obituaries are cultural artifacts used to provide public documentation of personal legacies, this study sought to determine how children obituaries differ from traditional obituaries of those who have lived full lives. I content analyzed 63 children's obituaries to determine how they differ in intention and use of linguistic devices fr
