Phase Polymorphism of [Cd(DMSO)6](ClO4)2 Studied by Differential Scanning Calorimetry
Five phase transitions of [Cd(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry, namely the three reversible transitions: stable KIa ↔ stable KIb at TC4 = 242 K, due to a change of the crystal structure, metastable KII ↔ metastable KIII at TC3 = 318 K, and metastable KII ↔ overcooled K0 at TC2 = 347 K, one irreversible transition: KIa → K0 at TC1 = 376 K, and melting at Tt ...
متن کاملPhase Polymorphism of [Co(DMSO)6](BF4)2 Studied by Differential Scanning Calorimetry
Five solid phases of [Co(DMSO)6](BF4)2 have been detected by differential scanning calorimetry (DSC). Phase transitions were detected between the following solid phases: stable KIb ↔ stable KIa at T C4 = (328± 2) K, metastable KIII ↔ undercooled phase K0 at TC3 = (383± 4) K, metastable KII ↔ undercooled K0 at TC2 = (399± 2) K and stable KIa ↔ stable K0 at TC1 = (404± 1) K. The title compound me...

Six solid phases of [Mn(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry. The phase transitions were found between the following solid phases: stable KIc ↔ stable KIb at TC5 = 225 K, metastable KIII ↔ metastable KII at TC4 = 322 K, stable KIb → stable KIa at TC3 = 365 K, metastable KII ↔ overcooled K0 at TC2 = 376 K and stable KIa → stable K0 at TC1 = 379 K. The title comp...
متن کاملHydration of thermally denatured lysozyme studied by sorption calorimetry and differential scanning calorimetry.
We have studied hydration (and dehydration) of thermally denatured hen egg lysozyme using sorption calorimetry. Two different procedures of thermal denaturation of lysozyme were used. In the first procedure the protein was denatured in an aqueous solution at 90 degrees C, in the other procedure a sample that contained 20% of water was denatured at 150 degrees C. The protein denatured at 90 degr...
