特性
导入和可视化
DIFFRAC。一枝displays 1D and 2D SAXS data, as well as Nanography maps. Supported data formats are brml, raw, ascii (two-column xy and three-column xye with different units), gfrm and tiff.
数据预处理
DIFFRAC。一枝allows extracting the pure scattering signal of the nanostructures straightaway.
在第一步中，使用玻碳作为参考或基于主光束强度比来确定样品的透射率。2D数据随后被切片或通过优化算法集成到1D数据中以进行进一步评估。
DIFFRAC。一枝can perform both the transmission calculation and the background correction automatically, without the need for user intervention, if the data measurement strategy is set up with DIFFRAC.WIZARD.
SAXS具体地块和评估
传统上，SAXS曲线显示为具有特定轴缩放的图，允许快速图形检查数据质量，并直接评估参数，如Guinier、pord和Kratky图。在DIFFRAC。一枝all plot types can be readily selected by name. Evaluation of the related parameters, such the radius of gyration (Rg), the forward scattered intensity, the Porod scattering invariant, surface-to-volume ratio etc. is done fully automatically or interactively in a step-by-step procedure.
基于模型的拟合
DIFFRAC。一枝features a non-linear least-squares fitting of 1D SAXS data based on direct modeling of nanostructures in solution using geometrical shapes (sphere, cylinder, etc.) or by dedicated polymer models (chains, Gaussian star, etc.). It also takes into account polydispersity and concentration effects for complete sample characterization. The corresponding model parameters are determined by fitting the experimental SAXS curve.
对距离分布函数
对距离分布函数(PDDF) p(r)是散射粒子内任意两点之间的距离分布。PDDF是粒子大小和形状的函数，通过sin傅里叶变换与散射曲线有关。
