Dynamics of ring polymer melts: Memory function approach
Nail Fatkullin, Carlos Mattea, Kevin Lindt +2
We investigated the static and dynamic properties of a Rouse ring polymer modified by introducing an effective, spherically symmetric, attractive potential of entropic nature and a…
The Rouse ring chain with attractive harmonic potential of spherical symmetry
Nail Fatkullin, Carlos Mattea, Kevin Lindt +2
The static and dynamic properties of a cyclic Rouse chain modified by the introduction of an effective, spherically symmetric, attracting potential of entropic nature is studied. I…
Molecular velocity auto-correlations in glycerol/water mixtures studied by NMR MGSE method
Janez Stepišnik, Carlos Mattea, Siegfried Stapf +1
Molecular dynamics in binary mixtures of water and glycerol was studied by measuring the spectrum of water velocity auto-correlation in the frequency range from 0.05 to 10 kHz by u…
On the theory of proton solid echo in polymer melts
N. Fatkullin, A. Lozovoi, C. Mattea +1
Based on a modified Anderson-Weiss approximation (N. Fatkullin, A. Gubaidullin, C. Mattea, S.Stapf, J. Chem. Phys. 137 (2012), 224907) an improved theory of proton spin solid echo…
On the theory of Double Quantum NMR in polymer systems: the second cumulant approximation for many spin I=1/2 systems
N. Fatkullin, C. Mattea, S. Stapf
General analytical expressions for Double Quantum Nuclear Magnetic Resonance (NMR) kinetic curves of many-spin I=1/2 systems are derived with an accuracy of the second cumulant app…
A simple scaling derivation of the shear thinning power law exponent in entangled polymer melts
N. Fatkullin, C. Mattea, S. Stapf
This paper has been withdrawn by the author, because it final version is published in: N. Fatkullin, C. Mattea, S. Stapf, Polymer 52 (2011) 3522.
Molecular velocity auto-correlation of simple liquids observed by NMR MGSE method
Janez Stepišnik, Carlos Mattea, Siegfried Stapf +1
The velocity auto-correlation spectra of simple liquids obtained by the NMR method of modulated gradient spin echo show features in the low frequency range up to a few kHz, which c…
