“…The samples along with the standards were irradiated in the ‘self-serve’ irradiation facility of Dhruva research reactor, Bhabha Atomic Research Centre, Mumbai for two hours. The irradiated samples were assayed by gamma spectrometry with a 30% relative efficiency HPGe detector with an energy resolution of 2 keV at 1333 keV of 60 Co. 25 The concentration of the dopants was estimated based on the specific activity of the standard oxides irradiated under the same condition.…”
Matching effective ionic radii of trivalent dopants with the host through judicious choice of dopants and codopants has emerged as a smarter strategy for improving OER catalytic activity of ceria than individual ion doping.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
