There have been some recent announcements in the news about the synthesis of Uranium Nitride. One announcement from Los Alamos National Labs mentions the use of photolysis to achieve the desired material: http://tri-lab.lanl.gov/index.php/energy-security/75-using-light-to-create-rare-uranium-molecule Another announcement from University of Nottingham mentions the use of sodium to achieve the desired material: http://www.nottingham.ac.uk/chemistry/news/uranium-nitride-breakthrough.aspx Are they talking about the same resulting material in both announcements? Are these 2 different methods of synthesis for the same material? Or are they the same synthesis path? If they are 2 paths to the same thing, then what are the pro's and cons relative to each other?
