This article provides an overview of a new integrated software tool for reduction and analysis of small-angle X-ray scattering (SAXS) data from fibrous collagen tissues, with some wider applicability to other cylindrically symmetric scattering systems. SAXS4COLL combines interactive features for data pre-processing, bespoke background subtraction, semi-automated peak detection and calibration. ...

The small angle X-ray scattering (SAXS) pattern of the homotetrameric asparaginase II from Escherichia coli was measured in solution in conditions resembling those in which its crystal form was obtained and compared with that calculated from the crystallographic model. The radius of gyration measured by SAXS is about 5% larger and the maximum dimension in the distance distribution function abou...

Glassy polycarbonate was subjected to cyclic stresses and the changes in its structure were studied by DSC, positronium annihilation lifetime spectroscopy (PALS), and SAXS. On increased exposure to cyclic loading, the enthalpy overshoot near T s increased in a manner similar to increasing physical aging. However, the 'hole' size as revealed by PALS increased, unlike physical aging. SAXS reveals...

The aqua ions of palladium(II) and platinum(II) undergo extremely slow hydrolysis in strongly acidic aqueous solution, resulting in polynuclear complexes. The size and structures of these species have been determined by EXAFS and small angle X-ray scattering, SAXS. For palladium(II), the EXAFS data show that the Pd-O and Pd···Pd distances are identical to those of crystalline palladium(II) oxid...

Poly(l-arginine) (PARG) and poly(l-glutamic acid) (PLGA) homopolypeptides were custom synthesized by precision N-carboxyanhydride ring-opening polymerization methods with two molar masses, matched for pairs of cationic anionic polypeptides (degrees n = 100 500). The conformations the probed using circular dichroism (CD) FTIR spectroscopy which revealed presence mainly polyproline II (PPII) conf...

Tomographic images with absolute units have been reconstructed successfully from Small Angle X-ray Scattering (SAXS) intensities of an interdiffusion layer a precipitation strengthened model alloy cut multilayered Al/Al–Zn/Al sample after heat treatment. Cross sectional specimen Zn concentration distribution was obtained the mass attenuation coefficient; volume fraction precipitates SAXS integr...

The aim of this paper is to introduce a new image analysis program "Nanoannotator" particularly developed for analyzing individual nanoparticles in transmission electron microscopy images. This paper describes the usefulness and efficiency of the program when analyzing nanoparticles, and at the same time, we compare it to more conventional nanoparticle analysis techniques. The techniques which ...

Small-angle X-ray scattering (SAXS) is a useful technique for nanoscale structural characterization of materials. In SAXS, and spatial information indirectly obtained from the intensity in spectral domain, known as reciprocal space. Therefore, characterizing structure requires solving inverse problem finding plausible model that corresponds to measured intensity. Both choice computational workl...

We studied the composition-dependent miscibility of polyamide 6 and biobased 4,10 (PA6/PA410) blends, as triggered by crystallization driven phase segregation. The blends were prepared extrusion in a wide composition range characterized X-ray diffraction (both in-situ ex-situ SAXS/WAXS), Differential Scanning Calorimetry (DSC), Polarized Light Optical Microscopy (PLOM) during non-isothermal cry...

To explore dense packings of soft colloids, scattering experiments are ideal to access the structure factor. However, for microgels, determination factor is difficult because low contrast polymer network and potential microgel interpenetration deformation that change form contribution. Here, we employ small-angle X-ray (SAXS) study soft, thermoresponsive microgels with poly-N-isopropylacrylamid...
