Additionally they are prone to interfere with the hydration kinetics thus playing a role in the very early structuring process of a cement-based mortar.
The structuring process has been additionally characterized by the hydrate phase development.

The POM macro-anions can interact with cationic surfactants toform complex structures, which are usually water insoluble [7-9].
The related ED pattern, as inserted in Fig. 4b, exhibits diffraction spots arrayed in two regular hexagonal structures, indicating an obvious single-crystal nature, suggesting that the {Mo154}-(TTA)n complexes can grow into single-like crystal structures.
Both organic and inorganic components have well-defined molecular structures, therefore the complexes are quite identical in shape and size, which enables them to form 3D, highly ordered quasi-single crystal structure.
Hexagonal packing (corresponding to bodycentered-cubic structure in 3D) is a natural choice for the packing of soft, spherical objects.
(1) {Mo154} clusters form uniform complex structures with cationic surfactants that can self-assemble into quasi-single crystal structures with around 70 to 200 nm by hexagonal packing

The structure of the obtained initiator was confirmed by the NMR spectroscopy and quantitative analysis methods.
The structure of synthesized poly(2-alkyl-2-oxazoline)s was confirmed by UV-Vis spectroscopy and NMR spectroscopy.
The temperature of their phase separation varies depending on the length and structure of the alkyl substituent.
Conclusion It was shown that the synthetic potential of the polyoxazolines chemistry may be considerably expanded with the use of sulfochlorinated calixarene based initiators.

One strategy is to modify the structure and properties of already known materials.
One of the most promising substitutes for hexaferrite BaFe12O19 structure and properties modification is aluminum.

Such structures are sometimes mixed up in a given alloy.
This texture prevents a reliable structure determination.
The structure refinement shows that the martensitic phase exhibits an incommensurate modulated structure.
Similar distances are obtained in the martensite structure.
