Hello Ian:

    I was very interested in your post replying to the question about
    annealing silver.  You suggested that possibly nitrogen was fixed in
    the annealing procedure cited.  That would be very interesting
    because fixing nitrogen by chemical means usually requires a
    catalyst, high temperatures and high pressure (the Haber process
    producing ammonia). Some fairly recent work using unusual metal
    complexes showed the promise of greatly lowering temperatures and
    pressures, but I have not heard anything more about it.  If you have
    a reference for the process you suggested, I would appreciate your
    sharing it.
