Data on Fullerenes Described by Researchers at University of Idaho

February 11, 2014



By a News Reporter-Staff News Editor at Physics Week -- A new study on Fullerenes is now available. According to news reporting originating from Moscow, Idaho, by VerticalNews correspondents, research stated, "Lead sulfide (PbS) quantum dots stabilized by 1,2-benzenedimethanethiol can be synthesized by mixing Pb(NO3)(2) and Na2S solutions in ethanol under ultrasound irradiation."

Our news editors obtained a quote from the research from the University of Idaho, "The, PbS quantum dots (2.7 and 3.6 nm in diameter) are characterized by their absorption and fluorescence spectra in the near infrared region and by other surface analytical techniques. With addition of single-walled carbon nanotubes (SWNT) to the system, this ultrasound-assisted procedure allows attachment of PbS nanoparticles to SWNT surface via pi-pi stacking, thus providing a simple one-pot method for preparation of SWNT-PbS nanoparticle composite materials."

According to the news editors, the research concluded: "Using the ultrasound-assisted method for synthesizing silica composites containing PbS nanoparticles by a sal-gel process is also described."
