Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
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 ...

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

High‐Entropy Metal Phosphide for Efficient Hydrogen Conversion Reactions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, high‐entropy metal phosphide nanoparticles were synthesized via a cation‐binding phosphate–resin heating treatment strategy. Mn incorporation in Co0.62Fe0.20Ni0.14Cu0.23Mn0.38P effectively optimized the electronic structure, accelerated electron transfer among metal sites, lowered the free energy of hydrogen adsorption/desorption, and ...
