Figure 3. Schematic representation of the micro- and nanoscale morphology of gel-type (a) and macroreticular (b) resins [13], Level 1 is the representation of the dry materials. Level 2 is the representation of the microporous swollen materials at the same linear scale swelling involves the whole polymeric mass in the gel-type resin (2a) and the macropore walls in the macroreticular resin (2b). The morphology of the swollen polymer mass is similar in both gel-type and macroreticular resins (3a,b). Nanopores are actually formed by the void space surrounding the polymeric chains, as shown in level 4, and are a few nanometer wide.

FIG. 3. HistoneHl kinase activity and schematic representation of the morphology of one-cell mouse embryos (3A) and two-cell stage blastomeres (3B) bisected at the respective G2 phases. N ote that histone H1 kinase activity rises autonomously in anucleate halves of both embryos and blastomeres. However, the degree of the autonomous activation is lower than in theit nucleate counterparts. Activity detected in nucleate halves obtained during respective M phases was taken as 100%. Note that the nucleate halves obtained at theit respective G2 stages do not activate histone HI kinase to the levels observed in the halves obtained in the M phase, and that the mitotic disassembly of microtubules was observed only when the level of histone HI kinase was between 35% and 46% in anucleate halves.

Fig. 15.1. Schematic representation of morphologic changes in a cell during apoptosis. On reception of an apoptotic signal, an adhesive cell (a) begins to become rounded (b) and the nuclear DNA condenses (c). The DNA is fragmented and the nucleus begins to break down into discrete chromatin bodies (d). Finally, the cell disintegrates into several vesicles (apoptotic bodies) (e), which are phagocytozed by neighboring cells (f).

Recently, a new concept in the preparation of TPVs has been introduced, based on the reaction-induced phase separation (RIPS) of miscible blends of a semicrystalline thermoplastic in combination with an elastomer, with the potential for obtaining submicrometer rubber dispersions. This RIPS can be applied to a variety of miscible blends, in which the elastomer precursor phase was selectively crosslinked to induce phase separation. Plausible schematic representation of the morphological evolution of dynamic vulcanization of immiscible and miscible blends is shown in Fig. 9. For immiscible blends, dynamic vulcanization leads to a decrease in the size...

FIGURE 1.19. Schematic representation of a hierarchic pattern formation in by an electric field. First, the top polymer layer is destabilized, in similarity to Fig. 1.9, leaving the lower layer essentially undisturbed. In a secondary process, the polymer of the lower layer is drawn upward along the outside of the primary polymer structure, leading to the final morphology, in which the the polymer from the lower layer has formed a mantle around the initial polymer structure.

Two kinds of morphology have been found in the specimens observed by cross-section TEM. The aluminum films evaporated on the control film and the corona treated film have the usual "Rod Like structure (RLS) morphology whilst on the fluorine treated film the aluminum layer presents a " Non Rod Like structure" (NRLS) i.e. the grain boundaries are not crossing the full thickness of the metallic layer. A schematic representation of both morphologies is shown in figure 2.
