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 made them of great practical interest. However, relations between the macromolecular structure and the functional properties are far from being understood. More specifically hierarchical…

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. Mechanical and physical properties of solid polymers are resulting from its crystallization kinetic which affects both the nanoscale structure…

Determination of polymer crystallinity

Application Note - AN-XE01 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…
