Macromolecular packing

Neither can it be attributed to the more hydrophilic nature of TGDM, because similar results were obtained for copolymers of MMA and ethylene glycol dimethacrylate. An alternative hypothesis was explored that crosslinking results in less efficient macromolecular packing, and hence to increased accommodation of water in mlcrovolds. However, this hypothesis was tested by... 

Using the scheme of macromolecular packing of a LC polymer and the values of the electron density distribution (Fig. 15a, b) the authors calculated one-dimensional correlation functions y x) obtained by Fourier-transform of X-ray scattering intensity curves. Figure 15c shows a one-dimensional correlation function yx (x) for two polymers with identical... 

A diverse range of factors has been shown to influence, often profoundly, the aggregation of amyloidogenic proteins and peptides. These include amino acid composition and sequence peptide length, concentration, pi and solubility and environmental conditions such as pH, temperature, solvent, metal-binding, macromolecular packing, membrane interactions and post-transitional modifications. Some of these effects are outlined below. 

There have been few reports to date on quasicrystaUine structure foimatimi from BCPs. Hayashida et al. obtained a 2D quasicrystaUine structure, a tUing pattern with 12-fold symmetry, from an ABC star BCP and homopolymer blend (see Fig. 3) [34]. The Bates group at the University of Minnesota generated a 3D dodecagonal quasicrystal from diblock and tetrablock copolymers [33]. These unique structures are mediated by macromolecular packing frustration. However, a substantial number of unanswered questions about the stmcture formation await further in-depth studies of these interesting morphologies.
