Small-angle neutron scattering rheology

It is not possible to discuss all the methods available for characterizing foods critically and systematically in a single volume. Methods pertaining to interfaces (food emulsions, foams, and dispersions), fluorescence, ultrasonics, nuclear magnetic resonance, electron spin resonance, Fourier-transform infrared and near infrared spectroscopy, small-angle neutron scattering, dielectrics, microscopy, rheology, sensors, antibodies, flavor and aroma analysis are included. 

Fig. 8 A slight modification of the structure can lead to completely different properties, as is illustrated by methyl-substituted his-urea compound 14 that, in contrast to gelator 13. forms a typically weak gel. The oscillatory rheology experiment shows the weak gels characteristic frequency dependency of G and G" (right), and small-angle neutron scattering studies revealed that the molecular wires are only two molecules thick, as depicted in the tentative model in the middle.

A series of similar, mixed polymer, surfactant systems has been studied by small angle neutron scattering techniques in order to determine the size of the aggregates. The results obtained are consistent with the rheological interpretation presented here and will be reported separately. ...
