Two atomic absorption techniques, acid digestion followed by conventional flame analysis and directanalysisof solidsamples with the graphite furnace, were compared forthe determination of copper in fingernails. Nail samples, from 11 persons, containing between 5 and 50 1zg/gof copper, were analyzed by both methods. There was good correlationbetween resultsofthe two.The furnace requires less sam...
While many promising applications have been demonstrated for vertically aligned carbon nanotube (CNT) forests, lack of consistency in results (e.g., CNT quality, height, and density) continues to hinder knowledge transfer and commercialization. For example, it is well known that CNT growth can be influenced by small concentrations of water vapor, carbon deposits on the reactor wall, and experim...
