Promising combined biocompatible polymers (polyvinyl alcohol, gelatin, collagen, their complexes) with high strength, water retention, porous structure, etc.
Consequently, protein systems are structure-forming and stabilizing, with certain surface properties.
The ultimate fracture stress (determined using a conical plastometer) approximately corresponded to that for protein systems, structured by functional animal protein.
The microstructure features are apparently related to the molecular structure of the dispersed phase.

However, the breadth and lack of well-resolved structure in this band has been a serious impediment to studying its nature.
Here, we report the first observations of highly resolved 1.7 K photoluminescence (PL) structure in this region.
At lower energies, we observe highly structured PL in the 3.28-3.44 eV range with at least eight separate components.
The strength and detailed structure of the defect-related PL band typically varies dramatically with crystal polarity in the case of c-oriented platelets.
The structure of these bands also varies markedly from sample to sample (see Fig. 5), suggesting that many variants of the structural defects are present.

The results of structural, physical chemistry and mechanical properties study of the nitrided were obtained on equipment of Experimental IMET-LECO Center in Moscow.
It specifies that the nitrated coatings have complex graded inhomogeneous structure.
The martensite structure form in the third cover zone and also contains residual austenite(near 20%) and nitrides.

The steel 25X5M with 5%mass Cr form perlite-bainite structure (α -Fe + γ’ -phase on base Fe4N).

Comparing with other methods, electrospun membrane has high specific surface area, high porosity and the three-dimensional reticulate structure.
The morphology and structure of the membranes are examined by SEM to observe morphological changes occurring in the membranes with mass loss.
Based on this terminology, those samples had a macroporous structure.
The water contact angles on different surface structure types (100/0 Fig.2A) were less than electrospun fiber membranes (100/0 Fig.2B).

Uranyl-salophen complexes are well-studied complexes in terms of structure and property [7].
Uranyl ion is easily bound by the ligand to form a sandwich-type structure of uranyl-salophen-silica gel (USSG).
The complex was mixed with APTS to form the sandwich-type structure of uranyl-selophen-APTS.
The structures of salophen, uranyl-salophen complex and USSG are shown in Fig, 1.
Structures of salophen, uranyl-salophen and uranyl-salophen-silica gel (USSG), and the illustrated procedure of separation and enrichment of phosphopeptides.

Therefore, it is obviously that the chemistry of oxygen at the surface has played an important role when PS is exposed to air and has to be considered in theoretical models for this problem.
Then oxidized clusters are built up by substituting H and Si atoms of the initial full hydrogen-passivated structures with oxygen.
Some of these structures are shown in Fig. 1, take Si10-core-based case for example.
For each model, the first step is to relax the structure with all the freedom, and once the optimization is achieved, the electronic properties are calculated.
Calculations of the electronic structure of silicon quantum dots: oxidation-induced redshifts in the energy gap.

The materials based on foam metals and foam ceramics are produced by doubling the structure of the polymer matrix, especially foam polyurethane, followed by burning out the polymer [1].
This structure ensures a higher degree of bonding and rigidity of the entire structure of the foam metal and anisotropy of the mechanical properties.
A serious problem of the foam-metallic catalysts is their corrosion during oxidation reactions which may lead to partial or complete failure of the structure of the support.

Moreover, it was demonstrated that the photocatalytic properties were strongly influenced by their crystal structure [1-3].
For example, BiVO4 with tetragonal structure had photo-absorption property in the ultraviolet region (band gap 2.9 eV), whereas those with monoclinic structure showed absorption property both under visible light (band gap 2.4 eV) and UV light, and the photocatalytic activity of monoclinic phase was much higher than that of tetragonal one [3].
For reference, the structure of MB is present in Fig. 1.

By heating kaolin at 650-800oC, water and OH was removed from interlayers of kaolin to form metakaolin, together with structure deformation to lose long-range order of silicon-aluminium layer structure[1-3].
Introducing MK into concrete improves the compressive strength, lowers the permeability and porosity, and refines the pore structure of concrete[5-7].
