We investigate spatial cross-correlations between two constituents, both belonging to the same microstructure. These investigations are based on two approaches: one via the measurement of the cross-correlation function and the other uses the spatial distances between the constituents. The cross-correlation function can be measured using the fast Fourier transform, whereas the distances are dete...

Polyurethane foams currently dominate the global foam market. Nevertheless, main drawback of these remains use toxic isocyanate reagents. To overcome this issue, several ways have been explored. The most promising route appears to be aminolysis 5-membered cyclic carbonates leading formation polyhydroxyurethanes (PHUs). However, lack reactivity systems using C5-cyclic limits application range PH...
