Elimination of Aspergillus parasiticus from nut surface

Low pressure cold plasma (LPCP) using air gases and sulfur hexafluoride (SF 6) was developed and tested for anti-fungal efficacy against Aspergillus parasiticus on various nut samples. Artificially A. parasiticus contaminated hazelnuts, peanuts, and pistachio nuts were treated with air gases plasma and SF 6 plasma for up to 20 min duration. The sterilizing effect of LPCP on A. parasiticus was

Uranium - Wikipedia

2  · Uranium is a chemical element with syol U and atomic nuer 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years
