Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Fluorimetric and ratiometric colorimetric dual-mode detection of organophosphorus pesticides based on carbon dots/DTNB

“…1D) exhibits an obvious diffraction peak at 2 θ = 27.9°, which is consistent with the (002) plane of graphitic carbon based materials. 39 In addition, the presence of other diffraction peaks shows a close match with the pattern recorded for standard ammelide. 40…”

Construction of Nitrogen‐abundant Graphyne Scaffolds via Mechanochemistry‐Promoted Cross‐Linking of Aromatic Nitriles with Carbide Toward Enhanced Energy Storage

“…The architecture feature of Gra‐1, N‐Gra‐1, and N‐Gra‐2 was characterized by the X‐ray diffraction (XRD) patterns, with two peaks at 2θ = 26.2° and 43.5° (Figure S6, Supporting Information), indicating the graphitic structure of the as‐afforded skeletons close to the graphite. [ 32,33 ] Graphitic morphology of the as‐afforded scaffolds was further illustrated by (high resolution)‐transmission electron microscopy ((HR)‐TEM) images, which exhibited sheet‐like architectures displaying a set of lattice fringes with a pacing of 0.34 nm and was consistent with the interplanar distance being calculated from the (002) diffraction peak at 2θ = 26.2° (Figures S7 and S8, Supporting Information). Successful introduction of nitrogen‐doping in N‐Gra‐1/2 was verified by the elemental analysis, in which the nitrogen content of N‐Gra‐1 and N‐Gra‐2 was 6.28 wt.% and 4.93 wt.% (Figure 2A), respectively.…”

Ultrafast and Ultralarge Lithium‐Ion Storage Enabled by Fluorine‐Nitrogen Co‐Implanted Carbon Tubes

“…The XRD patterns of both FNCT and NCT in Figure a exhibit a broad peak indexed to the (002) plane, implicating features of amorphous carbon. [ 11 ] Nevertheless, the (002) peak position of FNCT shifts to a lower angle relative to NCT as a result of the extra introduction of fluorine. Based on the Bragg equation, the interlayer spacing of FNCT and NCT was calculated to be 3.68 and 3.44 Å, respectively.…”
