“…The other band at 595 cm −1 is assigned to the Y-O vibration mode. A new phase of yttrium oxycarbonate has been observed during the thermal decomposition of YProp 3 in air at 500 • C. The formation of this compound was observed, as a common feature, during the thermal decomposition of Y metal-organic compounds [19].…”

Thermal degradation behaviour of the Ni(II) complex of 3,4-methylenedioxaphenylaminoglyoxime was investigated by TG, DTA, and DTG at a heating rate of 10°C min−1under dinitrogen. The acquired experimental data shows that the complex is thermally stable up to 541 K. The pyrolytic decomposition process occurs by melting metal complex and metal oxide remains as final product. The energies of the reactions involved and the mechanism of decomposition at each stage have been examined. The values of kinetic parameters such as activation energy (E), preexponential factor (A) and thermodynamic parameters such as enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG) are also evaluated.

“…The kinetics of decomposition for LF is studied by non‐isothermal methods. The equations of Coats–Redfern [ 18 ] and Piloyan–Novikova [ 19 ] are applied for calculating the activation energy, order of reaction, frequency factor, enthalpy, entropy of activation, and Gibbs free energy for LF. The equations used are given below:…”

Semi‐organic materials consisting of organic and inorganic semiconductors, exhibit the characteristic properties like strong optical nonlinearity and thermal stability. Lithium Fumarate (LF) is grown as a semi‐organic single crystal using lithium hydroxide and fumaric acid employing a slow evaporation method with de‐ionized water as the solvent. Classical NucleationTheory (CNT) is used to calculate the speed of LF nucleation. By altering the temperature, the thermogravimetric (TG) models, namely Coats–Redfern and Piloyan–Novikova equations are used to calculate the kinetic parameters such as enthalpy, Gibbs free energy, real heat power, and entropy of activation values. The width of the metastable zone in the LF crystal is determined by evaluating the relationship between supersaturation and temperature and it is found to exhibit a linear dependence on temperature and possess positive solubility. Lithium Fumarate's (LF) photoconductivity test shows that the grown crystal has positive photoconductivity. Photoluminescence studies conclude that Correlated Colour Temperature (CCT) values and color purity of LF crystal are suited to the green light emitting devices and flat panel displays.
