Research output: Contribution to journalArticle


Signatures of heterogeneous ensembles composed of multiple types of random oriented particles are represented by the angular autocorrelation functions of the systems. These signatures are retrieved by averaging oversampled angular correlation functions calculated from simulated high throughput X-ray diffraction patterns. Using a component signature matrix, the composition of the heterogeneous system will be directly calculated from the signature of the ensemble. Dynamic composition of a heterogeneous ensemble is determined by fluctuation X-ray scattering using the angular autocorrelation functions as signatures.
