DE-SC0022082 (spectroscopy characterization). The work of R.S. and V.B. is supported by the National Science Foundation under award no. DMR-1729297 (DFT calculations). The work of J.L. and Y.S.Z. is supported by the New Cornerstone Science Foundation through the Xplorer Prize. This ...
Polarized Raman spectroscopy A Horiba LabRAM HR coupled with a confocal microscope was used. A 785 nm laser source provided excitation for all the measurements, focused through a × 50 long working distance objective. The polarization of the monochromatic light was altered using a rotating quarter...
Bulk shale samples with clear lamination structures were polished and underwent micro-X-ray fluorescence spectroscopy (Micro-XRF) analysis. In order to obtain organic geochemical data from different lamina, shale samples with clear lamina interfaces and of sufficient thicknesses were chosen for micro...
two catalysts were characterized in detail. The X-ray absorption near-edge structure (XANES) and Extended X-ray absorption fine structure (EXAFS) spectroscopy were conducted to study their chemical states and coordination environment of the Cu center [17,18]. As shown in Fig.2a, Cu K-edge ...

The X-ray photoelectron spectroscopy (XPS) curves of the monomer 1a and the as-formed polymer (2) are shown in Figure 3A. A thin layer of 1a and 2 formed by pressing the samples onto a Cu tape was used for XPS measurements. The C 1s binding energies for 1a and 2 were 286.5 and ...
(SEM–EDX) or proton induced X emission spectroscopy (PIXE), are of little use for their identification. There is a single, notable exception: the indirect identification of Tyrian purple is made possible by the presence of two bromine atoms in the structure of 6,6′-dibromoindigotine. This...
Dye-sensitized solar cells (DSCs) remain an interesting photovoltaic concept, although recent times have seen their envisioned broad-scale applications being replaced with more niche ones. Nevertheless, as a key component of DSCs, titanium(IV) oxide (TiO
Review Reports Versions Notes Abstract Quantifying the organic carbon content of soil over large areas is essential for characterising the soil and the effects of its management. However, analytical methods can be laborious and costly. Reflectance spectroscopy is a well-established and widespread method...
