StepScan DSC technique was used for the study of the glass transition phenomenon. This method allows relatively good monitoring of reversing and non-reversing processes, and thus is very useful tool for glass transition studies of wide type of glass-forming materials, including inorganic glasses as well as organic polymers. In this work, experience with the StepScan DSC technique is summarized. Some interesting results of its application are presented, such as determination of glass transition temperature independent on thermal history of glass, discovered relationship between the slope of temperature dependence of C p in T g, and Angel’s index of fragility and estimation of viscosity glass transition temperature, T g,η.

Investigation of thermal decomposition kinetics of taurine
The non-isothermal thermal decomposition of taurine was investigated by means of thermogravimetric analysis (TG) and differential thermal analysis (DTA). The experimental data were treated using Flynn–Wall–Ozawa, Doyle, Kissinger, and Šatava–Šesták methods, respectively. The results show th ... more
Thermodynamic analysis of the hydrogen peroxide decomposition parameters
This paper discusses the estimation of the decomposition parameters of the liquid–gas-steam system, which is produced by the hydrogen peroxide decomposition at isobar conditions. The thermodynamic analysis calculates the two critical concentrations, which mark the phase transitions of the s ... more
