Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS
The 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 ...

Analysis of Combustion Instability in Liquid Fuel Rocket Motors [PDF]
The development of a technique to be used in the solution of nonlinear velocity-sensitive combustion instability problems is described. The orthogonal collocation method was investigated. It found that the results are heavily dependent on the location of

ChemSusChem, 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.
