Studies from University of Economics in the Area of Fullerenes Described (Size distributions of fullerene surface clusters)

July 4, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Fullerenes. According to news reporting originating from Vladivostok, Russia, by NewsRx correspondents, research stated, "We present an exactly solvable generalization of the rate equation model for irreversible growth with size-independent capture numbers which includes desorption of monomers. It is shown that the universal size distribution shapes depend on the sole parameter, the ratio between the characteristic diffusion and adsorption areas."

Our news editors obtained a quote from the research from the University of Economics, "We perform a statistical analysis of the scanning tunneling microscopy images of C-60 clusters deposited onto In modified Si(1 1 1)root 3 x root 3-Au surfaces at different temperatures and deduce the experimental size distributions. These distributions have an essentially asymmetric shape with a much faster decay toward larger sizes."

According to the news editors, the research concluded: "Fitting the data with theoretical distribution shapes yield the estimates for some important kinetic parameters, in particular, the temperature-dependent diffusion lengths and effective lifetimes of C-60 monomers."
