In this work, ZnO nanoparticles (NPs) were successfully synthesized and coated with oleic acid (OA). The mean diameter of these NPs (ZnO-OA) was around 11.5 nm, their core characterized by XRD coating FTIR Raman. Homogeneous dispersions at different concentrations (0.10, 0.25, 0.50, 0.75 1.00 wt%) ZnO-OA in polyalphaolefin 40 (PAO40) oil thermophysically tribologically characterized. Both density viscosity values increased the concentration NPs, reaching relative increments 0.5% 4.0%,...
Raman spectroscopy is a label-free technique for the detection and structural analysis of molecular materials. Unfortunately, signals are inherently weak, so very low number scattered photons available detection. Surface Enhanced Spectroscopy (SERS) useful method to amplify weak by an increment apparent cross-section analyte though local amplification electromagnetic field in close proximity metal nanostructures caused excitation localized surface plasmon resonances. Laser resonantly drives...
This paper provides new insights for the study of polymer degradation through detection markers released at surface using Al-coated SERS active substrates. Combining a nanodestructive sampling procedure with sensitivity allows achieving limits much lower than traditional characterization techniques, opening way to use as part an innovative strategy diagnose in polymeric museum artefacts. The method was applied artificially photo-aged model polymers and artworks.
Combining submicrometer-sized 3D structures with Al roughness for the development of sustainable SERS substrates.
Abstract Early evidence of materials decay can provide diagnostic insights to conservators and scientists enhancing the overall knowledge on art materials. Limited is available long‐term behavior synthetic natural polymers used in art. This research poses foundations for studies organic suffering from autoxidation processes, using nondestructive surface enhanced Raman spectroscopy (SERS) detection commonly present low molecular weight degradation products. Such products are here considered...
