Journal ArticleDOI
Fibrillar structure and mechanical properties of collagen
TL;DR: It was observed that the strain within collagen fibrils is always considerably smaller than in the whole tendon, which points toward the existence of additional gliding processes occurring at the interfibrillar level.
Journal ArticleDOI
Viscoelastic properties of collagen: synchrotron radiation investigations and structural model
R. Puxkandl,I Zizak,Oskar Paris,Jozef Keckes,W. Tesch,Sigrid Bernstorff,Peter P. Purslow,Peter Fratzl +7 more
TL;DR: In this paper, a simple structural model was proposed to describe the tendon at a hierarchical level, where fibrils and interfibrillar matrix act as coupled viscoelastic systems, and all qualitative features of the strain-rate dependence of both normal and crosslink-deficient collagen can be reproduced within this model.

First performance assessment of the small-angle X-ray scattering beamline at ELETTRA.
TL;DR: The double-focusing high-flux wiggler beamline dedicated to small-angle X-ray scattering (SAXS) and wide-angle OXS at ELETTRA has gone into user operation recently.
Journal ArticleDOI
The Importance of Protein-Protein Interactions on the pH-Induced Conformational Changes of Bovine Serum Albumin: A Small-Angle X-Ray Scattering Study
Leandro R.S. Barbosa,Maria Grazia Ortore,Francesco Spinozzi,Paolo Mariani,Sigrid Bernstorff,Rosangela Itri +5 more
TL;DR: It is confirmed that the protein concentration plays an important role on the pH-unfolded BSA state, due to a delicate compromise between interaction forces and crowding effects.
