Thermal decomposition of transition metal carboxylates. 2. role of evolution of microstresses in the kinetics of decomposition of anhydrous copper(ii) formate

Abstract: Dynamics of changes in microstresses during thermal decomposition of Cu(HCOO)2 crystals and their effect on the thermal decomposition kinetics were studied by IR spectroscopy at 105 to 120 °C. The formation of solid intermediate HCOOCu was observed, and the dynamics of its accumulation was followed. Kinetic regularities of transformation of HCOO groups were compared with those for gas evolution.

Kinetics of Monodisperse Iron Oxide Nanocrystal Formation by “Heating-Up” Process

Abstract: We studied the kinetics of the formation of iron oxide nanocrystals obtained from the solution-phase thermal decomposition of iron−oleate complex via the “heating-up” process. To obtain detailed information on the thermal decomposition process and the formation of iron oxide nanocrystals in the solution, we performed a thermogravimetric-mass spectrometric analysis (TG-MS) and in-situ magnetic measurements using SQUID. The TG-MS results showed that iron−oleate complex was decomposed at around 320 °C. The in-situ SQUID data revealed that the thermal decomposition of iron−oleate complex generates intermediate species, which seem to act as monomers for the iron oxide nanocrystals. Extensive studies on the nucleation and growth process using size exclusion chromatography, the crystallization yield data, and TEM showed that the sudden increase in the number concentration of the nanocrystals (burst of nucleation) is followed by the rapid narrowing of the size distribution (size focusing). We constructed a theore...
