Abstract: Irena, a tool suite for analysis of both X-ray and neutron small-angle scattering (SAS) data within the commercial Igor Pro application, brings together a comprehensive suite of tools useful for investigations in materials science, physics, chemistry, polymer science and other fields. In addition to Guinier and Porod fits, the suite combines a variety of advanced SAS data evaluation tools for the modeling of size distribution in the dilute limit using maximum entropy and other methods, dilute limit small-angle scattering from multiple non-interacting populations of scatterers, the pair-distance distribution function, a unified fit, the Debye–Bueche model, the reflectivity (X-ray and neutron) using Parratt's formalism, and small-angle diffraction. There are also a number of support tools, such as a data import/export tool supporting a broad sampling of common data formats, a data modification tool, a presentation-quality graphics tool optimized for small-angle scattering data, and a neutron and X-ray scattering contrast calculator. These tools are brought together into one suite with consistent interfaces and functionality. The suite allows robust automated note recording and saving of parameters during export.

Conformational transition of a non-associative fluorinated amphiphile in aqueous solution
Marc B. Taraban,Li Yu,Yue Feng,Elena V. Jouravleva,Mikhail A. Anisimov,Zhong-Xing Jiang,Y. Bruce Yu +6 more
TL;DR: The resulting fluorinated asymmetric amphiphile remains monomeric well above its apparent critical micelle concentration and up to its solubility limit, as demonstrated by small-angle X-ray and neutron scattering, dynamic light scattering and NMR diffusometry techniques.

Gabriel G. Correa,Everton C. Morais,Rodrigo Brambilla,Arthur A. Bernardes,Claudio Radtke,Diogenes Dezen,Álvaro Vargas Junior,Nei Fronza,J.H.Z. dos Santos +8 more
TL;DR: The gentamicin concentration on the outermost surface and the zeta potential were identified as factors that affected the highest efficiency, as observed in the case of encapsulation via the base-catalyzed process.
Structural evolution during gelation of pea and whey proteins envisaged by time-resolved ultra-small-angle x-ray scattering (USAXS)
TL;DR: In this article , pea (PPI) and whey (WPI) protein isolate gels were produced at the same protein content and similar heating/cooling rate, and the process was monitored using rheology, microscopy and in situ ultra small-angle x-ray scattering (USAXS).
