Analysis of the conformation of worm-like chains by small-angle scattering: Monte-Carlo simulations in comparison to analytical theory

Solvent-Induced Length Variation of Cylindrical Brushes

“…Systematic deviations, however, occur with decreasing chain length. This is in accordance with recent computer simulations [17] of the scattering function of worm-like chains, which have demonstrated the Koyama approximation to become poorer for increasingly stiff chains, i.e., around one Kuhn length per chain.…”

Time resolved structure analysis of growing β-amyloid fibers

“…As a consequence, aggregates will be interpreted with the model of unperturbed worm-like chains with a distribution of the chain lengths L. The approach of Schurtenberger (Pedersen and Schurtenberger, 1996;Pö tschke et al, 2000) is applied to describe its particle scattering behaviour. Polydispersity is taken into account by means of a (Debye, 1947;Franken and Burchard, 1973;Zimm, 1948).…”

“…This approach turned out to successfully describe angular dependent scattering at all degrees of flexibility including both limits, i.e. the fully flexible coil as well as the stiff rod (Pö tschke et al, 2000). Model fits were performed according to the procedure outlined in Appendix A.…”

Spatial Correlation of Spherical Polyelectrolyte Brushes in Salt-Free Solution As Observed by Small-Angle X-ray Scattering

“…47 In this case the measured intensity should scale with q -1 as expected for a rodlike structure (see the discussion of this point by Guenon et al). 32 It is to be understood, however, that in the case of the dense systems under consideration here this part of I(q) only comes into play for the highest q values in which parasitic scattering and other problems of the background may impose severe difficulties for the evaluation of data.…”
