TL;DR: In this article, Fourier transform (FT) Raman and infrared spectra of the stratum corneum of human skin were used for the first time and compared with assignments from the FTIR spectrum.
Abstract: Fourier transform (FT) Raman and infrared spectra of the outermost layer of human skin, the stratum corneum, were recorded. Assignments consistent with the FT Raman vibrations were made for the first time and compared with assignments from the FTIR spectrum. The results demonstrate that FT Raman spectroscopy holds several advantages over FTIR in studies of human skin. The molecular and conformational nature of human skin, and modifications induced by drug or chemical treatments, may be assessed by FT Raman spectroscopy.

TL;DR: In this article, the effect of copper loading on the pore structure of mesoporous copper catalysts was investigated in the hydrogenation of dimethyl oxalate to ethylene glycol (EG).
Abstract: Copper-containing mesoporous HMS catalysts prepared via a one-pot synthesis method based on sol−gel chemistry have been systematically characterized focusing on the effect of copper loading. Structural characterization of a series of different copper loading samples was performed by means of N2 adsorption, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, temperature programmed reduction, N2O titration, and X-ray photoelectron spectroscopy. It is concluded that the copper loading has a great influence on the pore structure of the catalyst. On the basis of the characterizations, the copper species on calcined CuO/HMS samples and reduced Cu/HMS samples were assigned. The synergetic effect between the Cu0 and Cu+ is considered to be responsible for the enhanced catalytic performance in the hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The maximum ratio of Cu0/Cu+ obtained via tuning the copper loading can result in the highest DMO hydrogenation a...

TL;DR: A very efficient, fast and convenient approach for exploring promising nanoassembly materials for water treatment, and a possible mechanism of Cu(2+) removal with the assembly of LDH-NCs@CNs was proposed, showing the deliberation of the assembly on water decontamination.
Abstract: We report on the efficient removal of heavy metal ions from simulated wastewater with a nanostructured assembly. The nanoassembly was obtained via direct assembling the performed anisotropic layered double hydroxide nanocrystals (LDH-NCs) onto the surface of carbon nanospheres (labeled as LDH-NCs@CNs). It was found that the maximum adsorption capacity of the nanoassembly toward Cu2+ was ∼19.93 mg g–1 when the initial Cu2+ concentration was 10.0 mg L–1, displaying a high efficiency for the removal of heavy metal ions. The Freundlich adsorption isotherm was applicable to describe the removal processes. Kinetics of the Cu2+ removal was found to follow pseudo-second-order rate equation. Furthermore, the as-prepared building unit of the assembly, including LDH-NCs, CNs, and the assembly, as well as Cu2+-adsorbed assembly, were carefully examined by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), nitrogen sorption measurements, and X-ray photoelectron spectroscopy (XPS)....
