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 ...

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 ...

Disproportionate Belowground Carbon Loss and Ecotone Sensitivity in Boreal Peatland Wildland Fires: Insights From LiDAR and Field Data

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Peatlands play a critical role in the global carbon (C)‐climate cycle, acting as vast long‐term stores of disproportionately large quantities of C relative to their land area. In recent decades, climate‐driven shifts in fire regimes and peatland hydrophysical properties have occurred across Canada's boreal regions, increasing concerns about ...
