Thermal and spectroscopic analysis of Co(II)–Fe(III) polyglyoxylate obtained through the reaction of ethylene glycol with metal nitrates

The role of ionic liquids in the synthesis of the high-temperature superconductor YBa2Cu3O7−δ

“…This band corresponds to the interaction of ethylene glycol as a ligand with the metal cations. 27,28 Therefore, these spectra provide information about how the interaction happens in two separate ways; one will be between the chloride and the metal cations and the second, between the molecule of ethylene glycol and the metal cations. The formation of such complexes will change the chemical environment of the system; thus, changes can be observed in a shift to higher values of the bands in the wavelength range of 3000-2800 cm -1 ( Figure 1B blue line), corresponding to C-H stretching of the alkanes, and 3700-3000 cm -1 , belonging to the O-H stretching of the ethylene glycol and of the overall hydrogen bonding network of the DES.…”

Crystallization kinetics of gehlenite glass microspheres

“…Thermoanalytical methods, such as differential thermal analysis (DTA) and differential scanning calorimetry, are the best suited and most commonly used methods to study the thermal properties of various systems [14][15][16][17][18][19][20]. To get the most trusted information about phase relations, thermodynamic properties and nucleation/crystallization behaviour of prepared systems, the results of thermal analysis are usually supplemented by SEM and X-ray powder diffraction analysis [21][22][23][24][25].…”
