Aluminium and Magnesium Comparison Open Science Requirement - Particle Design, Fabrication, and Measurement

This work follows an open-science data-sharing approach by providing the numerical output tables underlying the final FTIR spectrafigures for aluminum (Al) and magnesium (Mg) particle samples, along with the essential metadata needed for reuse. Measurements were collectedon a Thermo Fisher Nicolet 8700 FTIR using an unpolarized PIKE VeeMAX III specular reflection accessory at 30° incidence, with spectra reported inabsorbance-style units derived from reflectance. The shared materials include the spectral axis in wavenumber, the plotted ordinate, a clear statement ofconversions/corrections applied, and a documented MATLAB-based processing workflow used to generate the final plotted results. Samples consist ofrandomly oriented particles in a 2D array on a substrate. This report enables others to interpret the dataset and reproduce the reported spectra andderived peak metrics.
