Four major improvements have been made in the ZRD–SEARCH–MATCH program [Frevel (1965), Anal. Chem. 37, 471–482]; namely, (1) restriction of the file of standards to the 298 most frequently encountered phases, (2) utilization of a single index file based on the most intense reflection, (3) incorporation of a novel search function, and (4) revision of the quantitative matching of powder patterns.
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.
