DSC can be used to determine the enthalpies of formation for the 3d transition metal oxalates

Chemical Thermodynamics and Thermal Analysis, 2022
Differential scanning calorimetry has been used to measure the enthalpy of formation for manganese, iron, cobalt, nickel, copper and zinc oxalate. By adding a flameless combustion catalyst (CuO) and using scans of 2 K min−1 in static air, the values ...

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...
