Has anyone ever noticed something like the following? 
 Several metals, their oxides and both carbide and oxide
 ceramics per probed with pyridine usig temperature
 programmed desorption on the differential scanning 
calorimeter.  A second set of samples were probed with 
diethylamine.  Only one material desorbed both of these
 bases at the same temperature and, curiosly, at the same 
temperature at which the Neel magnetic phase transition
 occurs.  This material was nickel monoxide and the
 temperature was 252 deg. C.
