Lamellae structure and crystallinity analysis of semicrystalline polymers
Polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) is a versatile piezoelectric polymer well-known and studied for its ferroelectric and pyroelectric properties.
Size distribution of Gold Nanoparticles
SAXS was employed to characterize various complex nanoparticle samples: monodisperse systems (with a narrow standard deviation or broad distribution) and bimodal mixtures with different ratios. Nanoparticles (NPs) are indispensable in numerous applications, ranging from coatings and cosmetics to drug delivery systems, where they are frequently employed even at exceptionally low…
Phase diagram of lipid nanoparticles obtained with SAXS
Lipid Nanoparticles (LNPs) have attracted considerable attention as promising drug carriers due to their biocompatibility and ability to encapsulate...
SAXS as a tool to study Lipid Nanoparticles
Lipid nanoparticles (LNPs) are one of the most exciting technologies in the drug delivery world. Previously used to study lipid nanoparticles and lipoplexes, small angle X-ray scattering (SAXS) has proven to be an excellent technique for characterizing the structure of LNPs.

Shear alignment of Pluronic block copolymers
The structural evolution of P123 Pluronics was monitored and analyzed through shearSAXS measurements performed with the Xenocs Couette stage Poloxamers, also known under commercial names as Pluronics®, Synperonics® or Kolliphor® are a class of synthetic triblock copolymers that are composed of polyethylene oxide (PEO) and polypropylene oxide (PPO) blocks. They…
Shearing of clay minerals in suspension
Investigation of smectite suspension shear behavior through SAXS measurements performed with the Xenocs Couette stage Clay minerals are a group of hydrous aluminosilicate minerals that are commonly found in soils, sediments, and rocks. The most common types include kaolinite, illite, and smectite, each with its own distinct characteristics and uses.…
Mass specific surface area determined by SAXS
In this Application Note, the XSACT software package is used to process the SAXS data and determine the specific surface area of SiO2 powder samples. Both the invariant and the absolute-scale methods are employed, and the results are compared with the obtained from BET measurements and analysis.
Characterization of protein intermolecular interactions
SAXS was used to study the effect of pH and protein concentration on the self-interaction process of a BSA system in solution Bovine serum albumin (BSA) is a non-glycosylated globular protein found in bovines. It is widely used in drug delivery, immunodiagnostic procedures and in clinical chemistry due to its…
