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.

An adiabatic solution calorimeter and measurements of a standard reaction for solution calorimetry
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1973 This paper discusses in detail the design, construction, and performance of the vacuum jacketed, adiabatic solution calorimeter which was used for the work in the certification of two NBS Standard Reference Materials for solution calorimetry. As a test for the calorimetric precision the following enthalpies of reaction were measured (referred to the ...

The enthalpy of formation of MoF6(l) by solution calorimetry
Journal of Research of the National Bureau of Standards, 1978 Enthalpies of reaction of MoF6(ℓ) in NaOH solutions, of MoO3(cr) in NaOH solutions, of NaF(cr) in MoO3-NaOH solutions, and of NaF(cr) in H2O(ℓ) were measured to obtain the enthalpy of reaction of MoF6(ℓ) in infinitely dilute NaOH solution: MoF 6 ( ℓ ) + 6 OH - ( aq ) = MoO 3 ( cr ) + 6 F - ( aq ) + 3 H 2 O ( ℓ ) Δ H ∘ ( 298.15 K ...

Pressure perturbation calorimetry of apolipoproteins in solution and in model lipoproteins [PDF]
Proteins: Structure, Function, and Bioinformatics, 2009 AbstractHigh‐density lipoproteins (HDLs) are complexes of lipids and proteins (termed apolipoproteins) that remove cell cholesterol and protect from atherosclerosis. Apolipoproteins contain amphipathic α‐helices that have high content (≥1/3) and distinct distribution of charged and apolar residues, adopt molten globule‐like conformations in solution ...
