The syntheses of triazole, sulfur‐containing diazole and N‐phenylthiatriazole analogs of imidazole angiotensin II antagonist, DuP 753, are reported. 5‐Butyl‐3‐[(2‐trifluoromethyl)phenyl]‐2,1,3,4‐lH‐thiatriazole‐2‐one biphenyltetrazole (63) is found to have good in vitro activity.
Ultra-thin gate oxides grown by rapid thermal processing in N20-based oxidation ambients were evaluated. Gate oxide integrity was improved by incorporating more nitrogen in the thin gate oxides and by diluting oxidation ambients in inert gases.
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.
