Part 3/9:
Grignia compared aspects of the untreated and treated nickel meshes, noting the resulting surface morphologies. The untreated nickel mesh exhibited a higher degree of apparent carbon contamination, attributed to residual carbon from the adhesive used during the sample preparation process. This raised concerns about the accuracy of elemental identification, as the detection limitations of the SEM precluded hydrogen detection and could falsely elevate carbon readings due to interference.
To better understand the structural integrity and purity of the nickel mesh, Grignia illustrated how luminescent surface areas indicated potential contamination sources, including handling residue and environmental dust, affecting the elemental composition readings.
