In this case, doping amounts to 12 Si-C replacements, the total number of atoms in the original structure remaining unchanged.
This means that the atomic structure is expected to feature Se chains which interlink Ge(Se1/2)4 tetrahedra.
On the one hand, GeSe4 could comprise a phase separated structure made of Ge(Se1/2)4 tetrahedra and Se chains.

[21] The expressions for all the partial structure factors in the Bhatia-Thornton form can be found in H.E.

When supplied with additional chemical constituents, the aluminate and silicate present in fly ash or slag cement arrange into a polymeric structure with similar properties to hydrated cement.
Geopolymer Structure.
While the geopolymer chemistry and properties are well researched, geopolymer materials are not seeing widespread use despite their associated benefits.

The aim of this research is to study the structure and electrical properties of amorphous carbon thin film.
The structuring of a family of amorphous carbons with different sp3 fractions 0–90% and properties ranging between those of diamond and those of graphite opens a large number of possible applications.

Optical and related properties such as the functional groups, structure, and absoption were characterized by using FTIR, Infrared and Raman Spectroscopy and absorption (UVVis).
In these reactions, the silica xerogel structure tends to shrink due to the loss of the hydroxide (OH) groups.

X-ray Computerized Micro-Tomography (CMT) is an increasingly popular method for the 3D imaging of materials structures [16], and particularly of composite materials.
Figure 3 shows that the effective reaction constant of the porous structure may be recovered as a function of the Thiele modulus; the results are in excellent agreement with the analytical solution.
Example of a large scale infiltration with a low Thiele modulus. a) Rendering of the structure at four infiltration times. b) Porosity histograms at 20% residual pore volume.

As everybody knows, magnetite has interesting properties due of its particular structure.
This indicates that the crystalline structure of Fe3O4 is preserved in the composites. 4.2.
The no collinear spin structure due to the pinning of the surface spins at the interface of the magnetic nanoparticles and the polyaniline coating reduces the total magnetic moment of the nanoparticles.
Samples show a core shell structure with both magnetic and conductive properties related to the ratio PANI/ Fe3O4.

All materials were mesoporous but contained micropores in their structures.
This material had a low branched structure.
This process results in linear low-branched structures of a polymer.
These structures have lower BET surface areas and pore volumes.

The influence of deposition parameters on the structure and properties of Ni-P and Ni-Mo-P deposits are compared and discussed.
It is well known that the crystalline state and structure of coatings may influence their corrosion behavior.
The surface of Ni-P deposit exhibits a dense and fine structure with low porosity and little defects.
However, the surface of the Ni-Mo-P film prepared in a basic electrolyte shows a coarse grain structure with many serious cracks.
The Ni-P alloy demonstrates a dense and fine surface structure with low porosity and exhibits near noncrystalline state.

However, the parameters of maximum absolute elongation and elongation have a slight difference, which indicates the same structure of the films.
These forces cannot be changed without changing the fundamental nature of matter and the structure of the material.
An increase in the elastic modulus can occur due to a decrease in the distance between atoms in the irradiated structure of the sample.
This increase occurs due to a decrease in the distance between atoms in the structure of the sample.
