Recent Findings from University of Vale do Paraiba Has Provided New Information about Chalcogens

June 3, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Chalcogens is the subject of a report. According to news reporting from Sao Paulo, Brazil, by NewsRx journalists, research stated, "In the present paper we report the production of vertically aligned carbon nanotubes exfoliated (at the tips) by oxygen plasma for electrochemical applications. The fast and dry process produces graphene oxide tips and oxygen functionalization The electrodes are evaluated by cyclic voltametry by ferri/ferrocyanide redox couple and applied for electrochemical detection of lead (II) by differential pulsed anodic stripping voltammetry."

The news correspondents obtained a quote from the research from the University of Vale do Paraiba, "The electrode presents high sensitivity (35.47 uA.uM(-1)) and low detection limit (48.3 pM). As far as we know, this is the lowest LoD in comparison with other works using CNT or graphene electrodes."

According to the news reporters, the research concluded: "The high electrochemical response is attributable to high density of functionalized edges on carbon nanotubes tips."
