In the article "Active Thermotic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe", which appeared in the "Open Chemical Physics Journal", authors Niels Harrit of the University of Copenhagen's Department of Chemistry, Jeffrey Farrer of Brigham Young University's Department of Physics and Astronomy, Steven E. Jones, and others state that thermite and nano-thermite composites in the dust and debris were found following the collapse of the three buildings. The article contained no scientific rebuttal and the editor in chief of the publication subsequently resigned.
