Nanostructured multiphase polymers with mobility contrast, such as semicrystalline polymers or block copolymers with two separate glass transitions, are usually characterized by the presence of an interphase material with in-between mobility. This in

We investigate the molecular dynamics within the crystallites of poly(e-caprolactone), PCL, crystallized from the melt by means of high-field 13C and low-field 1H NMR spectroscopy, addressing the question of whether it can be classified as a “cryst

Using simple and cheap low-field (1)H NMR methods such as the magic sandwich echo technique and FID component analysis, we determine jump rates for 180° chain flips in poly(ethylene) (PE) crystallites, which are comparable to literature data obtaine

We report on the investigation of cyclic and comparable linear poly(e-caprolactone)s (PeCL) with molecular weight between 50 and 80 kg/mol with regard to chain mobility in the melt and crystallinity using low-field solid-state 1H NMR. Our results fro

The dynamics of the polymer matrix in filled rubbers is modified by the presence of solid particles. We used low-field proton NMR to investigate model filled samples consisting of a dispersion of g...

The range of neutron energies encountered at workplaces extends from 10 −2 eV to 10 7 eV or even higher neutron energies. The monoenergetic neutron calibration fields cover the neutron energy range from 10 4 eV to 10 7 eV. Hence calibrations in so-

We review basic principles of low-resolution proton NMR spin diffusion experiments, relying on mobility differences in nm-sized phases of inhomogeneous organic materials such as block-co- or semicrystalline polymers. They are of use for estimates of

The 4.4 MeV photon reference field described in ISO 4037 is produced by the 12 C(p,p′) 12 C (E x = 4.4389 MeV) reaction using a thick elemental carbon target and a proton beam with an energy of 5.7 MeV. The relative abundance of the isotope 13 C in
