For the characterization of an epoxy resin composite material, the following analyses were performed: thermal analysis (TG/DTG/DTA) in nitrogen flow at five linear heating rates and under four quasi-isothermal temperature programs, coupled TG + FTIR

The paper discusses the effects of a 4-year natural ageing on hydrothermal stability of new and previously accelerated aged parchments and leathers. It was observed that natural ageing generally lowers the denaturation temperature (measured using DSC

Four new coordination polymers have been obtained solvothermally from the reactions of Zn(NO3)2·6H2O with 1,2-, 1,3-, or 1,4-benzedicarboxylic acids in the presence of various amino-alcohols: 1∞[Zn2(Htea)2(1,2-bdc)] (1), 1∞[Zn(H3tris)(1,3-bdc)(C

The thermal stability and the decomposition steps of bis(pyridine)manganese(II) chloride (Mn(py)2Cl2) were determined by thermogravimetry and derivative thermogravimetry. The initial compound and the solid compounds resulted from each step of decompo

DSC measurements carried out on type I collagen at different heating rates were used for the kinetic analysis of the endothermic processes of denaturation in water excess and of the phase transition in dry state. The application of isoconversional an

In this paper, a TG/DTG–DSC–FTIR study of type I collagen extracted from bovine Achilles tendon both in inert (nitrogen) and oxidative atmosphere (synthetic air and oxygen) from room temperature to 700 °C was performed. The thermal analysis resu
