Polymer phase transformation

Simultaneous SAXS/WAXS measurements of a semi-crystalline polymer during thermal processing enables determination of route for phase transformation. It is well known that polymers undergo a large series of thermal transformations, from the synthesis in the reactor up to the final product shaping, i.e. during injection molding processing or film formation.…

Overview of a surfactant structure

SAXS/WAXS measurements were performed on the Head & Shoulders Classic Clean Shampoo from Procter & Gamble and reveal its inner structure. Many personal care products are concentrated surfactant systems displaying a multi-phasic microstructure. To design new properties through innovative formulation and to control the latter during the production process, good…

Silk fiber nanostructure investigation

SAXS/WAXS measurements enable the determination of the characteristic dimensions and the semi-crystalline structure of Bombyx mori cocoon silk fibers. The excellent mechanical properties of silk fibers, such as their high strength and toughness, made them of great practical interest for numerous applications. The most ubiquitous domesticated silkworm, the Bombyx mori,…

Protein structure resolution

SAXS/WAXS investigation of the protein Sub-unit F of the eukaryotic V1V0 ATPase was performed using the Xeuss 2.0 SAXS/WAXS system, leading to its structure resolution. The Small-angle X-ray Scattering (SAXS) technique is now well known for studying biological systems and more specifically proteins in solution. SAXS measurements allow the determination…

Low detection limit of crystallinity

Low polyolefin crystallinity fraction down to 0.3 % was determined during a kinetic experiment using the Xeuss 2.0 SAXS/WAXS system in combination with an integrated temperature control stage, the Linkam HFSX350. Most polymer transformations from raw material to a finished product necessitate a processing step involving a melt (or molten…

Determination of polymer crystallinity

The level of crystallinity of a polyolefin was determined during a kinetic experiment using the Xeuss 2.0 SAXS/WAXS system in combination with an integrated temperature control stage, the Linkam HFSX350. Most polymer transformations from raw material to a finished product necessitate a processing step involving a melt (or molten state).…
