Introduction Differential scanning calorimetry (DSC) is extensively used in chemistry and physics to analyze, e.g. phase transitions of different compounds [ 1 , 2 ]. Recently this technique has been used with increasing
analyzed using thermogravimetry (TG) and differential scanning calorimetry (DSC). Based on these experiments, a thermal analysis procedure to estimate SOM loss using (Δ H comb SOM ) / (Δ H β–α Qz) was developed and tested on samples from two pile burn
Introduction The kinetics and mechanism of hydration in various cementitious systems can be investigated by use of calorimetry [ 1 – 5 ]. The heat evolution curve reflects the rate of reactions occurring in the hydrating system
the results obtained by the method of cone calorimetry ( ) and on the basis of the quantitative chemical determination of the specific emission of CO, CO 2 , HCN, NO 2 , HCl, and SO 2 at temperatures of 450, 550, and 750 °C, according to standard PN

fenofibrate were obtained by Zhou et al. [ 3 ] as a result of differential scanning calorimetry (DSC) and modulated temperature DSC (MTDSC) measurements. Crystallization studies performed by those authors indicated an intermediate tendency for fenofibrate to
Calorimetric measurements Calorimetry is a good method for studies on cement hydration during its first hours of action when chemical and physical processes occur most intensively. This technique bases on continuous measurements of heat released in
with beech wood at about 27 °C. The smoking was followed by ageing for 35 days (12 °C, 75% RH). During the experiment, the NaCl content, color, water activity, denaturation temperature and enthalpy (differential scanning calorimetry) were measured on
-cysteine and l -cystine reporting their molar enthalpies of formation. In the present work we report the thermal behavior of both compounds studied by differential scanning calorimetry (DSC) and variable temperature powder X-ray diffraction (PXRD) in the
period up to 21 days was necessary for the sponge cakes investigated by differential scanning calorimetry (DSC), because no retrogradation transition was registered up to the sixth day. The humidity and the temperature were kept constant in desiccator
