New Chalcogens Study Results Reported from Iowa State University

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Chalcogens. According to news originating from Ames, Iowa, by NewsRx correspondents, research stated, "Solid energetic composites have been used and studied in standard air environments, yet the contribution of atmospheric oxygen to reactive material combustion has not been investigated."

Our news journalists obtained a quote from the research from Iowa State University, "This study experimentally examines the effect of atmospheric oxygen concentration (4% or 93% oxygen) on energy propagation of nanometric aluminum with copper oxide (Al + CuO), iron oxide (Al + Fe2O3), calcium iodate (Al + Ca(IO3)(2)), and iodine pentoxide (1205). In all cases energy propagation was examined in terms of flame speed and higher in the high oxygen environments."

According to the news editors, the research concluded: "However, the convectively dominant reactions showed a smaller percent increase in flame speed mainly attributed to the reaction mechanism."
