Researchers from University of Pittsburgh Describe Findings in Materials Science and Physical Chemistry

March 7, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Science. According to news reporting out of Pittsburgh, Pennsylvania, by NewsRx editors, research stated, "We report an unusual enrichment and assembly of TiO2 nanocrystals at water/hydrophobic interfaces through oxidative hydrolysis of TiCl3 in water."

Our news journalists obtained a quote from the research from the University of Pittsburgh, "The assembly is a spontaneous process that involves on-water inorganic reaction and assembly in the absence of any organic phases. In this process, TiO2 nanoparticles are preferentially produced at water/hydrophobic interfaces."

According to the news editors, the research concluded: "When the surface tension of the aqueous phase is above a critical value, ca. 25-35 mN m(-1), these TiO2 nanocrystals can spontaneously accumulate at water/air interfaces to produce macroscopic sized sheets and tubes."
