In this study, the effect of variety of Nano- additives doping on the hydration resistance of the MgO-CaO system was investigated. Samples were prepared from calcined dolomite and magnesite. Nano-additives that contained cations with various valences (trivalent and tetravalent) used as  a dopant. The bulk density, apparent porosity and hydration resitance were studied and evaluated. Also, phase...

The lipophilic dicarboxylic acid-dicarboxamide macrocycle 1 is an efficient carrier for calcium and potassium transport through a liquid membrane. The process involves competitive Ca2'/K' symport coupled to proton antiport in a pH gradient. It presents a very pronounced phenomenon of pH regulation of transport selectivity from preferential K+ transport to preferential Ca2' transport as the pH i...

Rare-earth nickelates R$^{3+}$Ni$^{3+}$O$_3$ (R=Lu-Pr, Y) show a striking metal-insulator transition in their bulk phase whose temperature can be tuned by the rare-earth radius. These compounds are also parent phases of newly identified infinite layer RNiO2 superconductors. Although intensive theoretical works have been devoted to understand origin bulk, there only few studies on role hole and ...

Earth-Shelter construction is one of the aspects in architecture where the thermal mass of the earth behind the outer walls are applied in order to reduce heat loss and keep the internal temperature at human comfort range. In case of earth-shelter buildings, housing is especially important. As for its applicability the earth-shelter provides good housing. Typological studies of earth-shelter co...

In this work, the investigation of thermosensitive behavior P(CPAAm6C) highlighted formation particles with an average radius about 1940 nm in nitric acid. While hP(CPAAm6C) does not exibit behavior, it was shown polymer had floculation properties. The selective sorption properties two valuable carbamoylmethylphosphonated-based polymers regarding to Th/U/Gd mixtures were studied. influence tota...

For satellite propulsion, new material are developed to sustain harsh thermal and environmental conditions in the combustion chambers induced by development of “green” propellants less toxic than currently used hydrazine. In present study, hafnia-based materials with different amounts natures stabilisers (Lu2O3, Y2O3 Gd2O3) have been chosen for ceramic part system. Microstructures, Thermal Expa...
