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.

Sustainable Bio-Based Materials from Minimally Processed Red Seaweeds: Effect of Composition and Cell Wall Structure
TL;DR: In this paper , the use of whole seaweed biomass to obtain bio-based films for food packaging applications was reported, where four different species of agarophytes were minimally processed by melt blending and compression molding, and the effect of their composition and cell wall structure on the final performance of the films was investigated.

Conformational Flexibility Enables Function of a BECN1 Region Essential for Starvation‐Mediated Autophagy
Sangita C. Sinha,Yang Mei,Arvind Ramanathan,Karen Glover,Zhongyu Yang,Christopher L. Colbert +5 more
TL;DR: Cellular studies show that conserved FHD residues are required for starvation-induced autophagy, and the FHD likely undergoes a binding-associated disorder-to-helix transition, and conserved residues critical for this interaction are essential for starve-inducedautophagy.

Effect of genipin cross-linking on the structural features of skim milk in the presence of ethylenediaminetetraacetic acid (EDTA)
TL;DR: In this article, the casein nanogels formed using genipin as a cross-linking agent were studied by dynamic light scattering (DLS), transmission electron microscopy (TEM), small angle X-ray and neutron scattering (SAXS, SANS).

The kinetics of precipitation from supersaturated solid solutions
I.M. Lifshitz,V.V. Slyozov +1 more
TL;DR: In this paper, an analysis is made of the process whereby diffusion effects can cause the precipitation of grains of a second phase in a supersaturated solid solution, and the kinetics of this type of grain growth are examined in detail.
