精品干货：SCI论文中如何来描述SAXS实验结果？

1. 如何非常详细地描述 SAXS 的实验结果？

举例：

The SAXS pattern of the solvent-extracted PMO-SBA-16 shows three well-resolved peaks at very small scattering angles, with interplanar d spacings of 12.8, 9.03, and 7.38 nm. These three peaks can be indexable as (110), (200), and (211) reflections of the body-centered 3D cubic space group (Im3m), similar to that reported for the silica-based mesoporous counterpart SBA-16. The unit cell parameter of the cubic lattice is as large as 18.1 nm. This is the first large-pore PMO material that exhibits such a highly ordered 3D mesostructure. By contrast, the SAXS pattern of the solvent-extracted control sample F127 blank prepared in the absence of K₂SO₄ reveals the formation of amorphous gel.

A. LP-FDU-12 materials synthesized at low temperatures were first examined by X-ray diffraction (XRD) and further confirmed by the small-angle X-ray scattering (SAXS) method.The XRD pattern of S-17-100 shows six well-resolved diffraction peaks (SI). A typical SAXS pattern of sample S-17-100 (Figure 1a) also exhibits six peaks, which can be exactly indexed to the 111, 220,311, 331, 333, and 442 reflections of a fcc structure (Fm3m). The cell parameter is calculated to be 34.6 nm (33.0 nm from XRD).

B. The small-angle X-ray scattering (SAXS) patterns of as-made FDU-16 clearly show three well-resolved diffraction peaks with q values of 0.47, 0.64, and 0.80 nm^-1(Figure 1a). Four additional diffraction peaks at q values of 0.88, 1.04, 1.12, and 1.22 nm^-1 can also be detected. The q-value ratios of these peaks are exactly1:√2:√3:√4:√5:√6:√7 and canbe indexed as 110, 200,211, 220, 310, 222, and 321 Bragg reflections, respectively, associated with the body-centered cubic Im3̄m symmetry.

C. The bulk structure of the mesoporous silica prepared with 1 as template via the nanocasting technique was characterized by small-angle X-ray scattering (SAXS). SAXS has turned out to be a powerful technique with which to investigate the structure of two-phase systems, (i.e.,nanostructure materials that can be supposed to be composed of two domains ofconstant electron density). The SAXS diffractogram of the present sample is shown in Figure 2. It exhibits a significantly main peak at s ≈ 0.20 nm,^-1 which corresponds to the packing of the wormlike pores into a certain distorted 3D alignment. The position of th epeak is related to a length scale of approximately 5 nm, the averaged pore-to-pore distance, in good agreement with the TEM observation.

D. Small-angle X-ray scattering (SAXS; see the Supporting Information) reveals four well-resolved reflections, further confirming a highly ordered hexagonal mesostructure. 

E.  Small-angle X-ray scattering experiments confirmed the presence of two kinds of cubic structures  (C_D and C_P).
