In situ study of the deterioration of thiazole/gold and thiazole/silver interfaces during interfacial ion transport processes

Terphenylthiazole-based self-assembled monolayers on cobalt with high conductance photo-switching ratio for spintronics

“…For both molecules, in addi'on to the main N 1s peak associated to the C=N bond, a second peak is also observed and is likely associated to a "coordinated-like" form (C=N...Au) of nitrogen (sec'on 5 in the Suppor'ng Informa'on). This N 1s peak spliong is observed when the N atoms interact with a metal surface, [28][29][30] a possible situa'on considering the large 'lt angle of the molecules inferred from thickness measurements and calcula'ons (geometry op'miza'on, vide infra). This "coordinated-like" peak is further used as a fingerprint of a strong interac'on between the molecule and the substrate in correla'on with the electron transport proper'es of the molecular junc'ons (vide infra).…”

Backside SERS studies of inhibitor transport through polyelectrolyte films on Ag-substrates

“…2 [22]. A Renishaw inVia Raman microscope (Renishaw plc, United Kingdom) equipped with a LEICA DM2500 M microscope and an air cooled HeNe laser (632.8 nm) were used for the acquisition of SER spectra.…”

“…5d, MBI molecules adsorbed on the surface of Ag nanoparticles. Therefore, the MBI concentration was low at the SERS substrate surface and a low SERS signal was detected in the backside geometry [22]. MBI concentration at the substrate/polyelectrolyte film interface increased in Section 2 when the Ag nanoparticles were most probably almost covered.…”

“…SERS studies of polymer/metal interfaces were reported for investigations aiming at modelling the adsorption of polymers by coating the organic molecules on SERS active substrates [22,23]. The application of SERS in processes related to corrosion or diffusion through polymer/metal interfaces is not common.…”

“…1a). The permeability of PAA/PAH films for MBI uptake from aqueous solution was investigated using in situ backside surface enhanced Raman spectroscopy (in situ SERS) [22] and Electrochemical Impedance Spectroscopy (EIS). In situ SERS enabled the detection of MBI adsorbing to the SERS substrate/ polyelectrolyte interface.…”
