We have clearly demonstrated the different aggregate structures of isomeric phenols-formaldehyde monolayers by BAM and SMM. The synthetic amphiphilic phenols of structural isomers, o-, m- and / -HP, showed characteristic monolayer properties on the aq. formaldehyde subphase. The aggregate patterns are supposed to give a clue to understand the microscopic morphology of the commercially important phenolic resins. The micron-sized domains observed by SMM can be related to the surface or interior morphology of the bulk phenolic... 

The final level of physical characterization that is sometimes done is to determine the pore size distribution and the interior morphology of the hydrogel. While there are a number of slightly varying methods to measure the pore size distribution most of them utilize the concept of size-exclusion, i.e. particles that are larger than the size of the pores are excluded.

C -CP-MAS NMR provides subtle information about the degree of solvation of the polymer chains of a CFP in a given solvent and consequently it may be qualitatively correlated with the nanometer scale morphology of the polymer matrix. In fact, the prerequisite that enables a polymer framework to develop a nanoporosity is the ability of the polymer chains and its pendants to be suitably solvated by the liquid medium [26-28]. Therefore, C -CP-MAS NMR spectra provide the basis for a first level screening of the possibility of a CFP in a given solvent to be employed as an hexo-template, able to accommodate metal nanoclusters chemically produced in its interior (see below and Ref. [29]). 

By swelling with aqueous electrolyte, cations (and, to lesser extent, also anions) penetrate together with water into the hydrophilic regions and form spherical electrolyte clusters with micellar morphology. The inner surface of clusters and channels is composed of a double layer of the immobilized —SO3 groups and the equivalent number of counterions, M+. Anions in the interior of the clusters are shielded from the —SOJ groups by hydrated cations and water molecules. On the other hand, anions are thus... 

The elastic free energy AFe causes difficulty because of its sensitivity to the crystallization model assumed. To estimate AFe for lamellar morphology, consider first an important property of a network, amorphous or crystalline. Network crosslinks are considerably restricted in their fluctuations. Fluctuations of crosslinks several chains removed from a particular chain are therefore inconsequential for that chain. A chain in the interior of a path traced through several sequentially connected chains behaves as if the path ends are securely anchored at fixed positions ( 7). If Gj chain vectors make up the path, then... 

Proteins of the cytoskeleton play a central role in the creation and maintenance of cell shapes in all tissues. They serve multiple roles in eukaryotic cells. First, they provide structural organization for the cell interior, helping to establish metabolic compartments. Second, cytoskeletal structures serve as tracks for intracellular transport, which creates and maintains differentiated cellular functions. Finally, the cytoskeleton comprises the core framework of cellular morphologies.
