Abstract:

The new mercury (II) compounds with (L1), (L2) of the general formula [Hg(L)2], have been synthesized and characterized by elemental analysis, electronic and IR, Raman spectra and thermogravimetry and differential thermogravimetry techniques. The changes observed between the spectra of the ligands and of the complexes allowed us to stablish the coordination mode of the metal in complexes and the mechanism of C–H activation is discussed in detail. Thermogravimetry (TG), differential thermal analysis (DTA) and other analytical methods have been applied to the investigation of the thermal behavio

In this study, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) methods were used to study the structure, the thermal degradation kinetics, and the thermogram of sweet potato starch, respectively. The thermal decomposition kinetics of sweet potato starch was examined within different heating rates in a nitrogen atmosphere. Different models of kinetic analysis were used to calculate the activation energies using the thermogravimetric data of the thermal degradation process. The activation energies got from Kissinger, Flynn–Wall–Ozawa, and Ša

The methods of thermal analysis – thermogravimetry, differential thermal analysis – were used to study the catalytic system phosphor-molybdenum heteropoly acid–aluminum oxide. It is shown that the modification of aluminum oxide has a direct effect on the state of the phosphor-molybdenum heteropoly acid. On the surface of ƞ-Al2O3, phosphomolybdic acid is destroyed by interaction with strong Lewis’s acid sites of the carrier, while on γ-Al2O3 it retains the individuality, probably due to multipoint adsorption on weak Bronsted and Lewis acid sites of the oxide

Abstract:

Solid-state M-3-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 3-MeO-Bz is 3-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), X-ray powder diffractometry, infrared spectroscopy, and chemical analysis were used to characterize and to study the thermal behaviour of these compounds. The results led to information about the composition, dehydration, thermal stability and thermal decomposition of the isolated compounds.

Abstract:

The simultaneous thermal analysis method (thermogravimetry/derivative thermogravimetry + differential thermal analysis (TG/DTG+DTA) and determination of iodine index have been used for characterization of an experimental vegetable insulating oil exposed to thermal cyclic and isothermal accelerated aging in pure state and in contact with red copper. The results obtained by thermal analyses show that three main successive processes of thermo-oxidation occur at progressive heating of initial (un-aged) and thermal aged oil samples. The accelerated thermal aging determines the change of composition

Abstract:

Thermogravimetry was used to investigate the thermal decomposition of oxomemazine. Oxomemazine has three distinct degradation processes during non-isothermal decomposition. The Arrhenius equation, Coats-Redfern (CR), Horowitz-Metzger (HM), and Flynn-Wall-Ozawa (F-W-O) equations were used in this research to perform kinetic analysis of the first decomposition stage. Oxomemazine thermal stability is very important when it comes to how it can be stored, quality control, and how long it can be used. Using thermal analysis, scientists have been able to learn more about how drug compounds are stable

Abstract:

Dark chocolate is a confectionery product traditionally made from cocoa beans, sugar, and vanilla essence. The aim of the study was to investigate the thermal properties of dark chocolates and fats extracted from these chocolates using thermal methods of food analysis, such as differential scanning calorimetry (DSC) and thermogravimetry (TG). The profile of fatty acids in the fat extracted from the chocolates was also determined. The presence of three fatty acids (palmitic P, stearic S, and oleic O) constituting triacylglycerols—SOS, POP, POS, POO, and SOO—was observed in all the samples. The

Abstract:

High-density polyethylene (HDPE) geomembranes have been used for different applications in engineering including sanitation, such as landfills and waste liquid ponds. For these applications, the material can be exposed to aging mechanisms as thermal and chemical degradation, even to UV radiation and biological contact, which can degrade the geomembrane and decrease the material’s durability. This paper aims to present an experimental evaluation of two exhumed HDPE geomembranes, the first was used for 2.75 years in a sewage treatment aeration pond (LTE sample) and another was used for 5.17 year

Abstract:

The effects of Na2SnO3 and CuSnO3 on the thermal decomposition and fire performance of wood were characterized by thermogravimetric (TG) analysis, differential thermogravimetry (DTG), and thermogravimetry–mass spectrometry (TG–MS) analysis. The addition of these chemicals caused a decrease in the decomposition temperature, a reduction in weight loss, and an increase in the amount of char produced. The results showed that ion current intensity and ion peak area of the typical representatives of incombustible ion such as m/z = 18 and 44 MS signals were increased by the flame retardants but the i

Abstract A pavement brick taken from a Romanesque part of the church in Pác, in the Trnava County, Slovakia, was investigated by x-ray diffraction analysis (XRD) and thermal analyses as differential thermal analysis (DTA), thermogravimetry (TG) and thermodilatometry (TD). It was found that the brick contained dehydroxylated illitic clay, calcite and quartz. As revealed, dehydroxylation was completely finished and no redehydroxylation was observed. Partial decomposition of calcite was also found. The estimated firing temperature is between 600 °C and 700 °C.
