The Stability of Manganese Oxides Under Laser Irradiation During Raman Analyses: II. Layer Structures

open access: yesJournal of Raman Spectroscopy, EarlyView.
Manganese oxides are important geomaterials with diverse technological applications. Here, we investigate the behaviour of the most common Mn oxides with layer structures under irradiation by a 532‐nm laser, with intensity ranging from 23 µW/µm2 to 36.8 mW/µm2.

Label‐Free Detection of π‐Stacking Interactions During Tryptophan Self‐Assembling Into Amyloid‐Like Structures Using Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
Tryptophan (Trp) self‐assembling into amyloid‐like fibrils was characterized for the first time with surface‐enhanced Raman scattering (SERS). It was possible to identify several spectral characteristics of the self‐assembled structures. This allowed to detect and monitor, as function of time, of several intermolecular interactions such as hydrogen ...

pH‐Dependent Pitting Corrosion in Nickel Thin Films

open access: yesMaterials and Corrosion, EarlyView.
This study investigates pitting corrosion in nickel thin films under varying pH conditions and inhibitor presence. Surface defects and solution chemistry modulate pit formation, while simulations reveal metal redeposition driven by chemical potential gradients at the pit center.
