Report Summarizes Nuclear Physics Study Findings from Federal University (Synthesis and applications of O-18 standards for nuclear reaction analysis)

August 19, 2014



By a News Reporter-Staff News Editor at Physics Week -- Data detailed on Nuclear Physics have been presented. According to news reporting out of Porto Alegre, Brazil, by VerticalNews editors, research stated, "A new method to synthesize O-18 standard samples to be used in nuclear reaction analyses is proposed and investigated. This method consists of obtaining a (SiO2)-O-18 film on a Si substrate using a natural abundance SiO2 film as a passivation layer to prevent the isotopically enriched film to be exposed to the atmosphere and possibly degraded by it."

Our news journalists obtained a quote from the research from Federal University, "For that, sequential oxidation steps are performed followed by a controlled etching in aqueous hydrofluoric acid. Details of these steps are discussed as well as the stability of the synthesized samples."

According to the news editors, the research concluded: "Applications using these standard samples in the field of alternative semiconductors to Si (SiC and Ge), used in micro and nanoelectronics are also presented."
