Water-soluble phosphates and fluorides contribute to the formation of the structure of gypsum products with increased strength and water resistance [2,3].
Physical and mechanical tests carried out within the time specified by the standard do not provide information on the properties of the binder, since the process of structure formation has not ended.

In this study, activated by epoxy chloropropane, the magnetite core/functional organic shell structured particles are characterized in terms of chemical composition, particle size and electrophoretic mobility and act as the immobilized PGA carriers.
Firstly, the PAA, as the competitive inhibitor of PGA, could keep the structure of active center of PGA and decrease the loss of PGA activity in the reaction system.

Conclusions DSC can not provide any direct information about the chemical composition and structure of natural resins and waxes.
These thermodynamic properties are sensitive to the chemical composition and structure of the resins and waxes, and thus can be used in the identification of natural resins and waxes.

Scheme 1 Structures of synthesized DOPO-based phosphonamidates.
The peak at 1290 cm-1 is attributed to the P=O stretching vibration of the O=P-O-Φ structure, where Φ represents a polynuclear aromatic structure.
The bands at 1080 and 750 cm-1 is assigned to the stretching vibrations of P-O-P structure and out-of-plane bending vibrations of aromatic C-H for P-O-Φ complex structure [22].

The Ba6-3xR8+2xTi18O54 solid solutions have an orthorhombic tungstenbronze type-like structure with lattice parameter a≈1.22 nm, b≈2.23 nm, c≈0.77 nm.
Materials with large anisotropy in the crystal structure can be applied the texture engineering to obtain the single crystal-like properties [4, 5].
To clearly understand the correlation between the crystal structure and dielectric properties, evaluation of highly grain-oriented Ba6-3xR8+2xTi18O54 is a important subject of research.

TiO2: from nanotubes to nanopores by changing the anodizing voltage in floride-glycerol electrolyte Claudiu Constantin Manole1, a , Cristian Pirvu1,b, and Ioana Demetrescu1,c 1 Faculty of Applied Chemistry and Materials Science, University Politehnica Bucharest Str.
For the nanostructures growth at 80V the wider distribution of the structures generates a bigger amount of irregularities.
With the increase in voltage, the ordered structures shift from nanotubular aspect towards a porous distribution on the surface.
At 40V applied voltage, the nanotubes are incorporated by porous structures of the same diameter.
With the increase in voltage, the ordered structures shift from nanotubular aspect towards a porous distribution over the surface.

Crystal structure of indinavir base and calculated powder pattern Fig. 3 shows the molecular structure of indinavir with the hydrogen bond between the water molecule and the pyridine moiety, N(4)…HO(5).
The crystal structure of the monohydrate was determined and based on the reflections of the calculated powder pattern it is now possible to clearly identify indinavir monohydrate as a potential component in urinary stones from HIV-patients with X-ray powder diffractometry.
