Stacked morphologies

In recent research, Al-Hussein et al. [25] prepared an oriented low-density polyethylene with a parallel lamellar stack morphology where the c axes of the crystalline lamellae were parallel to the lamellar plane normals. For this structure, explicit equations can be obtained for the elastic constants in terms of the crystalline volume fraction and the elastic constants of the crystalline lamellae (cji, C33, C44, etc.) and the amorphous layer (cji, cfj, c, etc.).

PP/MMT blend and nanocomposites. The scattering patterns of the blend and the two nanocomposites are presented in rows 2-4 of Fig. 5.3. All materials show the mentioned transition into a microfibrillar stack morphology, but their initial stmcture is different from the initial structure of the pure PP. The scattering patterns appear rather blurred and a direct qualitative interpretation can only describe very general... 

It has been established that, when mesophase pitch is carbonized, the morphology of the pitch is the primary factor [20] in determining the microstructure of the resulting graphitic material. This may be attributed to the stacking behavior of mesophase molecules (quite similar to the planar stacking in turbostratic graphite), which may be visualized as shown in Fig. 5. 

Cells do not stop their proliferation upon reaching confluence, pile up in stacks (foci) of morphologically transformed cells that can be considered as an endpoint of neoplastic transformation (Fig. 5).
