- A new insight into polyurethane foam deterioration – the use of Raman microscopy for the evaluation of long-term storage conditions
Susana França de Sá, Joana Lia Ferreira, Ana Sofia Matos, Rita Macedo and Ana Maria Ramos

Four storage conditions have been assessed for polyurethane (PUR): open-air and enclosed systems (simple, anoxic and cold). Raman microscopy proved to be a powerful tool for the detection of PUR molecular deterioration. Hydrogen-bonding interactions were monitored based on C=O wavenumbers (1650-1800 cm-1), and a correlation was established between the broadening of the C=C band (1620 cm-1) and yellowing. Moreover, the high vulnerability of the supramolecular structure of PUR was highlighted, and new contributions for lowering PUR high deterioration rate were launched
- Lipid organization and stratum corneum thickness determined in vivo in human skin analyzing lipid–keratin peak (2820–3030 cm−1) using confocal Raman microscopy

In healthy human skin, the sharpness of the peak centered near 2880 cm−1, which characterizes the polymethylene backbone of long-chain lipids, might be used for determining the stratum corneum thickness. The maximum position and broadness of the Gaussian peaks centered at 2850 cm−1 show that near the surface and in the deep-located layers of the stratum corneum, the state of the lipids is more fluid and disordered compared to the medium layers (20–40% of the stratum corneum thickness).
- Effects of HPO42− and SCN− on the hydrogen bond network of water: femtosecond OHD-RIKES and FTIR measurements
Mengqi Hou, Anchi Yu and Rong Lu
Version of Record online: 21 JUL 2016 | DOI: 10.1002/jrs.4989
The effects of HPO42− and SCN− anions on the hydrogen bond (HB) network of water in their aqueous solutions were investigated by using both femtosecond optical heterodyne-detected Raman-induced Kerr effect spectroscopy (fs OHD-RIKES) and FTIR spectroscopy. Both fs OHD-RIKES and FTIR observations suggest that HPO42− has the ability to promote the HB of water in its aqueous solution. On the contrary, SCN− has the ability to disrupt the HB of water in its aqueous solution.
- Tip-enhanced Raman spectroscopy (TERS) on double perovskite La2CoMnO6 thin films: field enhancement and depolarization effects
Christoph Meyer, Sebastian Hühn, Markus Jungbauer, Sebastian Merten, Bernd Damaschke, Konrad Samwer and Vasily Moshnyaga
Version of Record online: 21 JUL 2016 | DOI: 10.1002/jrs.4986
In this paper, we demonstrate polarization-dependent tip-enhanced Raman spectroscopy (TERS) on double perovskite La2CoMnO6 thin films, grown on SrTiO3 (100) substrates, by using a scanning tunneling microscopy based setup in the side-illumination geometry. The obtained TERS spectra are analyzed for different polarization configurations. They are set in relation to the corresponding far-field spectra and are compared with theoretical selection rule calculations, considering a tip amplification and depolarization model for the tip-induced near field.
- Two-dimensional Raman spectroscopy study of ionogel phase formation in long-chain ionic liquid/water systems
Jonas Kausteklis, Vytautas Balevičius and Valdemaras Aleksa
Version of Record online: 15 JUL 2016 | DOI: 10.1002/jrs.4983
The phase behavior of the long-chain imidazolium-based room temperature ionic liquids [C10mim][Br], [C10mim][Cl] and water were studied by 2D Raman correlation spectroscopy and principal component analysis. The lower border fingerprint of liquid crystalline ionogel phase formation was found by monitoring the chemical shifts of the C–H stretching modes in the Raman spectra and the scores of the first and the second principal components as a function of the water content in the solutions.
