Researchers from Institute of Science Discuss Findings in Nanoparticles

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- New research on Nanoparticles is the subject of a report. According to news reporting out of Mulhouse, France, by NewsRx editors, research stated, "Bis(cyclopentadienyl)titanium dichloride (Cp2TiCl2) is a high performance additive under UV light activation for both i) radical photopolymerization reactions (when added to a Type I photoinitiator such as 2,2-dimethoxy-2-phenylacetophenone, the oxygen inhibition is reduced) and ii) a concomitant in situ photoinduced and oxygen mediated formation of Ti-based nanoparticles (diameters ranging from 45 to 220 nm). The photochemical properties of Cp2TiCl2 are investigated by steady state photolysis and electron spin resonance, and its photoinitiation ability checked."

Our news journalists obtained a quote from the research from the Institute of Science, "The nanoparticles (NPs) are well characterized by transmission electron microscopy. The high reactivity of Cp2TiCl2 under air is ascribed to a bimolecular homolytic substitution (the S(H)2 process is clearly demonstrated by density functional theory calculations and ESR experiments), which converts the peroxyls into new efficient initiating radicals. The photochemical in situ incorporation of Ti NPs has never previously been reported."

According to the news editors, the research concluded: "The synthesis of metal nanoparticles by a S(H)2 approach instead of the reduction of a metal salt appears to be a promising original method.' xlink:href='urn:x-wiley:10221336:media:marc201300924:marc201300924-abs-0001' >image
