Determination of silicate liquid thermal expansivity using dilatometry and calorimetry [PDF]

, 1992
A method for the determination of relaxed silicate liquid molar volume and expansivity at temperatures just above the glass transition is discussed. The method involves the comparison of heat capacity and molar expansivity in the glass transition region.

Polymorphism and Phase-Transition Thermodynamic Properties of Phenazone (Antipyrine)

Molecules
In this work, detailed information on the phase-transition thermodynamics of the analgesic and antipyretic drug phenazone, also known as antipyrine, is reported. It was found that the compound forms two polymorphs. Fusion thermodynamics of both forms was

Half-metallic ferromagnetism with high magnetic moment and high Curie temperature in Co$_2$FeSi

, 2005
Co$_2$FeSi crystallizes in the ordered L2$_1$ structure as proved by X-ray diffraction and M\"o\ss bauer spectroscopy. The magnetic moment of Co$_2$FeSi was measured to be about $6\mu_B$ at 5K.

Thermochemistry of yavapaiite KFe(SO4)2: Formation and decomposition [PDF]

, 2005
Yavapaiite, KFe(SO4)2, is a rare mineral in nature, but its structure is considered as a reference for many synthetic compounds in the alum supergroup. Several authors mention the formation of yavapaiite by heating potassium jarosite above ca. 400°C. To
