Structural Aspects and Thermal Degradation Kinetics of Water Treatment Plant Sludge of Moroccan Capital

Published in Waste and Biomass Valorization

This paper reports a study on the structural characterization, structural transformations with temperature, and non-isothermal degradation kinetics of urban drinking water sludge. Chemical composition analysis by quantitative energy dispersive X-ray fluorescence suggests that the sludge is mainly inorganic in nature with small fraction of organic m...

Thermal sensitivities of triazole derivatives and dinitrobenzene mixtures from the perspective of charge transfer

Published in Journal of Thermal Analysis and Calorimetry

Energetic material mixtures can be considered as the blends of fuel and oxidizing agents that release energy during redox reactions; therefore, the relationship between their thermal sensitivity and the electrostatic interactions between the electron donor (reductant) and electron acceptor (oxidant) in such mixtures was investigated as an indicator...

Calorimetric study of carbosilane dendrimers of the third and sixth generations with phenylethyl terminal groups

Published in Journal of Thermal Analysis and Calorimetry

In the present work, temperature dependences of heat capacities of carbosilane dendrimers of the third and sixth generations with phenylethyl terminal groups, denoted as G3[CH2CH2C6H5]32 and G6[CH2CH2C6H5]256, were measured for the first time in the temperature range from 6 to 520 K by precision adiabatic calorimetry and differential scanning calor...

DSC coupled with PCA as a tool for butter authenticity assessment

Published in Journal of Thermal Analysis and Calorimetry

The authenticity assessment of butter is still a big challenge for analytics. Due to its low cost, palm oil (PO) is the edible fat most frequently used as an adulterant in the production of butter. The aim of this study was to test the feasibility of the DSC technique coupled with principal component analysis (PCA) for the distinction of pure butte...

Acid Ionic Liquids as a New Hardener in Urea-Glyoxal Adhesive Resins

The effect of acidic ionic liquid (IL) as a new catalyst on the properties of wood-based panels bonded with urea-glyoxal (UG) resins was investigated. Different levels of N-methyl-2-pyrrolidone hydrogen sulfate ([HNMP] HSO4 (0, 1, 2, 3 wt %)) were added to prepared UG resin. The resin was then used for preparing laboratory particleboard panels. The...

Thermodynamic investigation of Rb2FeTi(PO4)3 phosphate of langbeinite structure

Published in Journal of Thermal Analysis and Calorimetry

The temperature dependence of molar heat capacity for Rb2FeTi(PO4)3 phosphate was investigated between T = 6 and 650 K by precision adiabatic vacuum and differential scanning calorimetry in this research. The anomaly was observed in the heat capacity curve, and its character was explained by magnetic disorder–order phase transition at T below 6 K. ...

Structural, electrical conductivity, and transport analysis of PAN–NH4Cl polymer electrolyte system

Published in Ionics

Poly (acrylonitrile) (PAN) and ammonium chloride (NH4Cl)-based proton conducting polymer electrolytes with different compositions have been prepared by solution casting technique. The amorphous nature of the polymer electrolytes has been confirmed by XRD analysis. The FTIR analysis confirms the complex formation of the host polymer (PAN) with the s...

Isoconversional analysis of copper recrystallization

Published in Journal of Thermal Analysis and Calorimetry

Recrystallization of Cu deformed under compression has been monitored by differential scanning calorimetry (DSC) with experiments carried out at constant heating rate. From these experiments, an isothermal crystallization process has been predicted by the classical Kolmogorov–Johnson–Mehl–Avrami (KJMA) kinetics and by model-free isoconversional ana...

Study of kinetics of α ⇔ β phase transformation in Ti–4.4 mass% Ta–1.9 mass% Nb alloy using differential scanning calori...

Published in Journal of Thermal Analysis and Calorimetry

The kinetics of α ⇔ β phase transformations in a Ti–4.4 mass% Ta–1.9 mass% Nb alloy has been studied as a function of heating and cooling rates in the range of 3–99 °C min−1 using isochronal differential scanning calorimetry. The transformation start (Ts), peak (Tp) and finish (Tf) temperatures show a systematic variation with heating and cooling r...
