New Carbon Research Study Findings Have Been Reported by Investigators at State University of Campinas

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- New research on Carbon Research is the subject of a report. According to news reporting from Campinas, Brazil, by NewsRx journalists, research stated, "The first- and second-order Raman spectra of carbon nano-onions (CNOs), produced via annealing of detonation nanodiamonds with a mean grain size of similar to 5 nm in the argon ambience at the maximal temperature of annealing process (T-MAX) varying from 1500 to 2150 degrees C, are analyzed together with the high-resolution transmission electron microscopy (HRTEM) images."

The news correspondents obtained a quote from the research from the State University of Campinas, "The combined analysis provides a deep insight into the annealing-induced atomic-scale structural modifications of the CNO nanoparticles."

According to the news reporters, the research concluded: "The Raman and HRTEM data unambiguously demonstrate the reduction in the number of defects in the CNO structure, as well as indicate the conversion from the diamond sp(3)-bonded carbon phase to the sp(2)-bonded carbon phase with increasing T-MAX and its almost full completion for T-MAX = 1600 degrees C."
