Keywords: raw natural rubber, aging, structure, properties.
The molecular structure, molecular weight and its distribution, P0, PRI, Mooney viscosity, processibility of raw natural rubber, curing characteristics of compounds and mechanical properties of vulcanites were studied by hot air aging.
With the method Zhang B-L studied the effective storage period of natural rubber [3], Li S-D studied the structure and properties of natural rubber after accelerated storage at 70˚C for 48 hours in the existence of P2O5 [4].
Molecular structure of natural rubber before and after hot air aging were measured by fourier–transform infrared spectrometer (PERKIN ELMER Spectrum GX) with resolution 4 cm-1.

The impact of their use on the properties of composites in the fresh and hardened state was analysed, and these impacts were related to, for example, their chemistry, grain morphology, loss on ignition, or fineness.
The possibility of using coarse-grained fly ashes, which does not differ much in its chemistry from fly ash, but whose activity is affected by inappropriate granulometry, is most often discussed.
Corse particle after grinding Fine particle of fly ash Corse particle before grinding Very reactive fine particles Less reactive fine particles Very reactive amorphous structure Less reactive crystalline phase Reactive amorphous phase Figure 1: Principle of mechanical activation [5] Experimental Part Mechanical activation of bed combustion fly ash by grinding For the experiment and verification of the possibility of using coarse-grained bed combustion fly ashes after their mechanical activation by grinding as an active admixture for the production of cement composites, 3 thermal power plants in the Czech Republic and Poland were selected as sources.

Therefore, it is urgent to create materials of a new generation capable of protecting people, technological equipment, buildings and structures from the effects of fire, radiation and other factors.
Summary The effect of the main structure-forming oxides Li2O/Al2O3, SiO2/Al2O3 and H2O/Al2O3 on the physical, rheological and colloidal-chemical properties of binders in the xLi2O-Al2O3-nSiO2-mH2O system has been studied.
The data obtained will form the basis for the creation of new generation of protective materials that, in the event of emergencies, can provide both the protection of people and technological equipment, buildings and structures.

This variation of lattice parameter values can be described in terms of crystal structure.
In crystallography, the structure of magnetite does not differ much from the structure of maghemite.
The inverse spinel crystal structure of oxidised magnetite remains, considering maghemite (fully oxidised magnetite) also consists of the same structure, with vacancies localised on the octahedral sublattice.
Magnetite’s structure consists of oxygen close-packed cube.

The morphologies and the structures of the samples were examined by a JEOL JSM-6390LV scanning electron microscopy (SEM) and a JEM-2010F transmission electron microscopy (TEM).
The diffraction peaks match well with the standard XRD date of Fe3O4 (JCPDS No. 19-0629) with a cubic inverse spinel structure.
The sample contain hysteresis loop that can be classified as type IV isotherms of porous structures.

Abstract.
Using a polymer template with micrometer-scale features to direct the ordered arrangement of 1, patterned structure with micrometer-scale local order was fabricated.
We greatly appreciate the generous gift of the PDMS molds from Professor Younan Xia, Department of Chemistry, University of Washington.

X-ray diffraction studies confirm the hexagonal structure of zinc oxide nanostructures.
The preparation conditions will have significant effect on the visible luminescence properties of ZnO which can alter the surface chemistry and luminescence properties of ZnO colloids [9].
Lattice structure is primitive and the space group is P63mc.
X-ray diffraction pattern confirms the hexagonal structure of the synthesized ZnO nanostructures.
SEM images show flower like structures of nanostructures.
