چکیده
CoxNi3-xP2O8 (0 ? x 3) solid solutions were synthesized via the chemical co-precipitation method. Variation of unit cell parameters and interatomic distances indicated that these with Ni3P2O8 structure are stable between 800 1200 °C in compositions 0 1.5 1000 when 3). When (2.5 3.0), lead to Co3P2O8 structure, being °C. The yellow colour compound changes pink or red Co(II) ions incorporated as formed. Bands corresponding second third electronic transitions octahedral coordination appear 450–600 nm UV-V spectra, they responsible observed colour. Absorbance visible spectra was also obtained from enamelled samples but a new band at 650 considerable absorbance > 1.0 increased blue amount, yellowish brown, green blue.

Synthesis and mechanical properties of Ti 3 GeC 2 and Ti 3 ( Si x Ge 1 − x ) C 2 ( x = 0 . 5 , 0 . 75 ) solid solutions
In this paper we report on the synthesis and characterization of Ti3GeC2, Ti3Si0.5Ge0.5C2, and Ti3Si0.75Ge0.25C2 solid solutions. Polycrystalline, fully dense, predominantly single phase samples of Ti3Si0.5Ge0.5C2, Ti3Si0.75Ge0.25C2, and Ti3GeC2 of varying grain sizes were fabricated by reactive hot isostatic pressing (HIP) or hot pressing of Ti, C, SiC, and Ge powders. Based on the lattice par...
متن کاملTheoretical Study of OH Adsorption on PdxCu3-x (x = 0-3) Nano Clusters
Adsorption of OH on the PdxCu3-x(x=0-3) small clusters is investigated by density functional theory calculations. It is found that OH adsorbs in three possible modes including on top, bridge and hollow sites while the structures where OH bridges between two atoms are the most stable structures. The Pd-Pd, Pd-Cu and Cu-Cu equilibrium distances for most of the systems...

Raman scattering study of Nd 1 − x Sr x MnO 3 ( x = 0 . 3 , 0 . 5 )
We report on polarized Raman scattering of single crystals of Nd1−x SrxMnO3 (x = 0.3, 0.5). Raman spectra of Nd0.7Sr0.3MnO3 show a significant change through the metal–insulator transition. In the ferromagnetic metallic phase phonon modes grow in intensity and number while the electronic continuum becomes more pronounced. We suggest that these effects are due to the strong competition between t...
