Raman peak deviations linked to TMV coat protein conformation were observed upon treatment at temperatures equal or higher than 85掳C, substantiating the rod-to-spherical shape transitions observed by TEM and the concomitant drastic loss of infectivity following plant inoculati...
Under an Elsevier user license open archiveSummary On account of its sensitivity to chirality, Raman optical activity (ROA), measured here as the intensity of a small, circularly polarized component in the scattered light using unpolarized incident light, is a powerful probe of protein structure and...

The current thermodynamic databases containing molar Gibbs energy (such as FACT database [26, 27]) allow routine construction TDM-SV for many multi-component melts and glasses. Malfait’s decomposition of Raman spectra and MCR Malfait et al. [28,29,30] proposed the method of numerical analysis...
The results from this work open the way to the use of handheld instrumentation for analysis of ink-based art works and documents and also provide a starting point towards the creation of a reference SERS database for dye identification.Saviello, Daniela...
The “hot spots” effect typically manifests at connections or gaps between noble metal nanoparticles, or in highly curved regions with a small radius of curvature, such as the corners or tips of nanostructures (the “lightning rod” effect), or at topographies with nanometer-scale roughness, ...

The pre-processing of the SERS spectral database consisted of using multiplicative scattering correction (MSC), baseline correction and Savitzky-Golay smoothing prior to the PCA analysis. 4. Conclusions Two Gram-positive bacteria species were successfully characterized and discriminated using Raman and ...
In all cases, when a period of writing ink storage on open air exceeds 1 to 1.5 years [22–24], it can be analyzed using Raman spectroscopy without preliminary sample preparation. If this period is insignificantly smaller, the removal of volatile component traces may be implemented by ...
In addition, the Raman Foods 2022, 11, 2871 6 of 13 spectrum of the string of sample C had a matching rate of 99.99% with polypropylene (PP) when compared with the standard database. Based on the above observations, it can be reasonably inferred that the composition of the filter bags ...
