Simultaneous determination of several crystal structures from powder mixtures: the combination of powder X-ray diffraction, band-target entropy minimization and Rietveld methods
TL;DR: In this paper, a method to reconstruct single-phase powder diffraction data from diffraction patterns of mixtures of several components and subsequently to determine the individual crystal structures is presented.

TL;DR: In this paper, non-invasive in situ monitoring of catalyzed chemical reactions can show and probe the stability of the catalyst and ensure a high yield of the desired chemical processes.

Screening for cocrystallization tendency: the role of intermolecular interactions.
TL;DR: The long-time self-diffusivities measured using pulsed gradient spin-echo nuclear magnetic resonance (PGSE NMR) are used to characterize the particle interactions in solutions for pharmaceutical cocrystallizing systems and are found to be stronger than the homomeric attractions between API and ligand.

A multicomponent calibration approach to the microabsorption problem involving inorganic mixtures
TL;DR: In this article, a multicomponent calibration approach is introduced to reduce the systematic bias that is not accounted for in conventional Rietveld analysis, and six ternary inorganic mixtures containing components with diverse mass absorption coefficients were prepared.

Development of 2D band-target entropy minimization and application to the deconvolution of multicomponent 2D nuclear magnetic resonance spectra.
TL;DR: A higher dimensional entropy minimization method based on the BTEM algorithm and related techniques were extended to large-scale arrays, namely, 2D NMR spectroscopy and it was possible to reconstruct the pure spectroscopic patterns and calculate the relative concentration of each species without recourse to any libraries or any other a priori information.
