Unlike reconstruction phenomena, the faceting of surfaces leads to structures, which exist in the bulk lattice already. In

• -binding proteins, such as filamin, into GUVs of 20 μm diameter. K+ ions were introduced into the vesicles by ionophores, thus triggering actin polymerisation. This polymerisation process was observed to induce morphological changes of the initially spherical vesicles towards irregular, asymmetric shapes

• regulation of morphological changes in such synthetic cells was explained by a balance of actomyosin cortical tension and mechanical resistance to rupture [71]. For the functional encapsulation of cytoskeletal proteins into lipid vesicles high physiological salt levels are mandatory and the fabrication

• stable holes and transform into cup-shaped liposomes, which finally turned into lipid bilayers (Figure 7) [81]. Reversion of these morphological changes could be achieved by diluting talin in the surrounding medium, which resulted in the lipid bilayers to transform back into closed liposomes. In future

They cannot be oxidised back and therefore block the active sites of the anode surface [31]. As shown in Figure 2c and Figure 2d, the morphological changes upon

The addition of FBC into Mater-Bi containing PEVOH as plasticizer for the preparation of Mater-Bi/FBC bionanocomposites showed morphological changes on the surface, as shown in Figure 2. It can be seen that FBC is easily incorporated in the Mater-Bi matrix and gives a
