Savitzky-Golay (SG) filtering, based on local least-squares fitting of the data by polynomials, is a popular method for smoothing and calculations derivatives noisy data. At frequencies above cutoff, SG filters have poor noise suppression; this unnecessarily reduces signal-to-noise ratio, especially when calculating In addition, filtering near boundaries range prone to artifacts, which are strong using We show how these disadvantages can be avoided while keeping advantageous properties...
Infrared Reflection Absorption Spectroscopy (IRAS) on dielectric single crystals is challenging because the optimal incidence angles for light–adsorbate interaction coincide with regions of low IR reflectivity. Here, we introduce an optimized IRAS setup that maximizes signal-to-noise ratio non-metals. This achieved by maximizing light throughput and selecting directly impact peak heights in spectra. The uses a commercial Fourier transform infrared spectrometer usable ultra-high vacuum (UHV)....
Single-atom catalysts are potentially ideal model systems to investigate structure-function relationships in catalysis if the active sites can be uniquely determined. In this work, we study interaction of C

Single-atom catalysts are potentially ideal model systems to investigate structure-function relationships in catalysis, if the active sites can be uniquely determined. In this work, we study interaction of C2H4 with a Rh/Fe3O4(001) catalyst that features 2-, 5-, and 6-fold coordinated Rh adatoms, as well clusters. Using multiple surface-sensitive techniques combination calculations density functional theory (DFT), follow thermal evolution system disentangle behavior different species....
