Studies from University of Limerick Reveal New Findings on Heavy Metals

February 28, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Heavy Metals are discussed in a new report. According to news reporting from Limerick, Ireland, by NewsRx journalists, research stated, "Palladium-catalyzed Suzuki, Heck, and Sonogashira coupling reactions were studied as reaction protocols for organic modification of Si surfaces. These synthetically useful protocols allow for surface modification of alkene, alkyne, and halide terminated surfaces."

The news correspondents obtained a quote from the research from the University of Limerick, "Surface oxidation and metal contamination were assessed by X-ray photoelectron spectroscopy. The nature of the primary passivation layer was an important factor in the oxidation resistance of the Si surface during the secondary functionalization. Specifically, the use of alkynes as the primary functionalization layer gave superior stability compared. to alkene analogues."

According to the news reporters, the research concluded: "The ability to utilize Pd-catalyzed coupling chemistries on Si surfaces opens great versatility for potential molecular and nanoscale electronics and sensing/biosensing applications."
