Discrete Mathematics, 1994 Let \(T_ G(\lambda)\) denote the number of \(T\)-colourings of graph \(G\) of order \(n\). The author shows that for each set \(T\) of nonnegative integers with maximal element \(r\), there is a polynomial \(Q_ G(\lambda)\) such that \(Q_ G(\lambda)= T_ G(\lambda)\) for all \(\lambda\geq r(n- 1)\).

Mass spectrometric investigation of the vaporization of sodium and potassium chromates: Preliminary results [PDF]
, 1979 Knudsen cell mass spectrometry was used to study the vaporization of sodium and potassium chromates. For both salts, the vaporization proceeds predominately by the reactions M2CrO4(c)=2M(g)+5/4O2(g)+1/2 Cr203(s) and M2CrO4(c)=M2CrO4(g) where M = Na or K.
