  1. SERS and Raman imaging as a new tool to monitor dyeing on textile fibres

    Sara Fateixa, Manon Wilhelm, Helena I. S. Nogueira and Tito Trindade

    Surface enhanced Raman scattering and Raman imaging were used with advantage in the monitoring of antimicrobial textile fibre dyeing. Our results show that by using SERS imaging, it is possible to distinguish the local distribution of Ag nanoparticles in the fibres and have an enhanced detection of the organic dye (methylene blue) on the textile surface

  2. Defects band enhanced by resonance Raman effect in praseodymium doped CeO2

    Version of Record online: 25 MAY 2016 | DOI: 10.1002/jrs.4943

    The origin of the Raman defects band at 570 cm−1 of praseodymium-doped ceria was revisited from in situ spectra using six different exciting lines between 458 and 785 nm at low temperatures after oxidizing or reducing treatment. The observation of overtones and the fast change of relative intensity with excitation wavelength were explained by a resonance effect around 514 nm, which involved a Pr4+ containing defect stabilized at the oxidized state.

  3. Characterizing the age of ancient Egyptian manuscripts through micro-Raman spectroscopy

    Sarah Goler, James T. Yardley, Angela Cacciola, Alexis Hagadorn, David Ratzan and Roger Bagnall

    We report the first in-depth, systematic study of the Raman spectra of black pigments on ancient Egyptian papyri with well-specified dates from the 4th century bce to the 10th century ce. The observed spectra are all characteristic of carbon black, but the shapes of the spectra change systematically with the manuscript date. This investigation offers new insights into the ink materials used in ancient Egypt and provides a conceptual basis for a new nondestructive means for estimating the dates of ancient papyri.

  4. Raman study of thaumasite Ca3Si(OH)6(SO4)(CO3)⋅12H2O at high pressure

    Using Raman spectroscopy, thaumasite compressed in water–alcohol and KBr media at high pressure (up to ~7 GPa) was studied. Behavior of thaumasite in both media was similar: several phase transformations in thaumasite at high pressures (4.4, 4.9 and 5.4 GPa in water–alcohol and close transitions in KBr medium) were identified by abrupt changes in characteristic Raman bands, including the strong band at 1074 cm−1. These transitions are assumed to be polymorphic.

  5. Raman mode-selective spectroscopic imaging of coenzyme and enzyme redox states

    Min Gu and H. Peter Lu

    Version of Record online: 22 APR 2016 | DOI: 10.1002/jrs.4915

    Thumbnail image of graphical abstract

    Surface-enhanced Raman scattering spectra of flavin mononucleotide (FMN) in different redox states, and in a redox active enzyme, nitric oxide synthase are studied. Incubated with silver nanoparticles coated with silica, spectra for oxidized and reduced FMN are obtained at different electrochemical potentials. Dominate Raman mode shifting belonging to typical redox-sensitive region of FMN is observed and analyzed.
