Absence of magnetic ordering in NiGa_2S_4
, 2007 Triangular-layered NiGa2S4, contrary to intuitive expectation, does not form a noncollinear antiferromagnetic structure, as do isoelectronic NaCrO2 and LiCrO2. Instead, the local magnetic moments remain disordered down to the lowest measured temperature.

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.The Gibbs free energy change of thermal decomposition of magnesium chromate was determined by various thermal analyses to be ΔG° = 63 000 − 75.8T (J/mol). This thermochemical data can be used to calculate potential diagrams and predict how to suppress the generation of hexavalent chromium.

Development and Characterization of Corrosion Resistant Coatings Using the Natural Biopolymer Chitosan [PDF]
, 2005 In the present study, chitosan was used as the basis for corrosion resistant coating. Chitosan suffers from two inherent weaknesses as a coating material namely high hydrophilicity and poor adhesive strength with Al 2024 T3 alloy.

Mass spectrometric investigation of the vaporization of sodium and potassium chromates: Preliminary results [PDF]
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.
