The effect of additives of nanofillers (NF) containing nanoparticles (NP) of copper oxide, stabilized by a polymer matrix of maleized polyethylene (MPE), obtained by the mechanochemical method, on the properties of composites based on isotactic polypropylene (PP) and high-pressure polyethylene (PE) was studied by X-ray phase (XRD) and thermogravimetric (TGA) analyzes. The enhancement of strength, deformation, and rheological parameters, as well as the thermo-oxidative stability of the obtained nanocomposites was revealed, which, apparently, is due to the synergistic effect of the interaction of copper-containing nanoparticles with anhydride groups of MPE. It is shown that nanocomposites based on PP/PE/NF can be processed both by pressing and injection molding and extrusion, which expands the scope of its application.

The influence of additions of nanofillers (NF) containing nanoparticles of copper and zinc oxides, stabilized by polymer matrix of high pressure polyethylene, prepared by mechano-chemical method on peculiarities of structure and properties of the metal-containing nanocomposites on the basis of epoxy diane resin (ED-20) by the methods of differential-thermal (DTA) and IR-spectral (IRS) and X-ray diffraction (XRD) has been investigated. It has been shown that an introduction of the metal-containing NF in composition with ED-20 shifts the cold curing reaction temperature from 90 to 75 °C, and hot curing from 125 to 100 °C and favors increase of its thermal stability, which is confirmed by growth of activation energy of thermal-oxidative destruction (Eact) from 210 to 225 kJ/mol. It has been shown that the nanoparticles of copper oxide increase the thermal properties of ED-20 and are the catalysts of curing reaction as evidenced by peak height on curing curve. In this case, the nanoparticles of zinc oxide practically don’t influence on thermal properties of nanocomposites on the basis of ED-20.

The high-pressure phase β -ZrB2O5 represents the first ternary borate in the system Zr-B-O. The compound was synthesized under high-pressure / high-temperature conditions of 7.5 GPa and 1100 °C in a Walker-type multianvil apparatus. The crystal structure was determined on the basis of single crystal X-ray diffraction data, collected at room temperature. The monoclinic zirconium borate crystallizes in the space group P21/c with the lattice parameters a = 439.04(9), b = 691.2(2), c = 896.8(2) pm, and β = 90.96(3)°. The structure is isotypic to the high-pressure phase β -HfB2O5, which is built up from layers of exclusively corner-sharing BO4 tetrahedra. Between these layers, the cations are coordinated square-antiprismatically by eight oxygen atoms.

This paper described the preparation method for composing high-grade synthetic diamond by water atomizing using FeNi30 powder catalyst.The FeNi30 powder was corroded by the 100Mpa super high-pressure water atomizing technique and selecting organic RY corrosion inhibitor. Contrast test of the original FeNi30 powder and the treated FeNi30 powder on synthetic diamonds were conducted under super high-temperature and high-pressure using cubic press. The result shows that after the FeNi30 powder was corroded,the FeO phase and Fe3O4 phase could not longer be found by X-Ray analysis.Furthermore,the oxygen content of the powder increased up to 100PPM under the natural condition for one year. After the powder was mixed with graphite powder, diamond could be made by isostatic pressing method. Its color became darker and its TTI value increased slightly. However, its penetrability was still different from the high-grade synthetic diamond made by gas atomizing FeNi30 powder catalyst.
