The results of studies of the ionic conductivity and the conjugated chemical diffusion coefficients (CCDC) in the nonstoichiometric LixCu1.75Se (0 ≤ x ≤ 0.25) ternary alloys are presented. It has been observed that the values of the ionic conductivity of Cu1.75Se copper selenide decreases with lithium doping in general owing to increasing the the activation energy. The increasing ...

Neutron-removal cross-section ( σ−xn ) measurements of neutron-rich light nuclei were performed on the COMBAS fragment-separator with a multi-detector Si telescope at intermediate energies (22-34) MeV/nucleon. The removals of one neutron from 8 Li and 9 Be, two neutrons from 6 He and 10 Be and four neutrons from 8 He were observed from the reactions on a Si-CsI(Tl) telescope. ...

Neutron transfer and nucleus breakup cross sections in ( 11Li + 9Be) -reaction are calculated at energy range up to 32 MeV/nucleon. The evolution of probability density of external weakly bound neutrons of 11Li and the probabilities of neutron transfer and nucleus breakup are determined based on a numerical solution of the time-dependent Schrodinger equation. Our calculation ...

Synthesis, X-ray phase analysis, electron microscopy and investigations of the thermoelectric and thermal properties of nanocrystalline copper sulfide alloys contained sodium are presented. At room temperature, the alloys are a mixture of three phases of copper sulfide - the monoclinic phase of Na2Cu4S3 , the hexagonal phase of Cu2S and the cubic phase of Cu9S5 (digenite). The ...

In this paper the experimental data on the differential cross sections for elastic scattering of 9 Be ions on 28 Si nucleus at the energies of the incident nucleus ranging from 12 to 201.6 MeV were analyzed in the framework of the double-folding model using the Paris NN-potential CDM3Y. A good agreement with the experimental angular distributions of differential cross sections ...

The nuclear shell model and its application to studying the structure of nuclei with deformed and spherical shapes are discussed. Calculations of level energies and wave functions in the shell model of deformed and spherical nuclei are performed for 7,8,11Li nuclei. A detailed calculation scheme for solving the radial Schrodinger equation is presented.

One of the main conditions for the transition to hydrogen energy is development of reliable, high-performance and cost-effective fuel cells, in which chemical energy is converted directly into electrical energy. The advantages of solid oxide fuel cells (SOFC) are: high electrical efficiency (50 - 60)%, in cogeneration with thermal energy the efficiency may reach 90%, and high ...

Cathode materials with mixed ion-electron conductivity (MIEC) are necessary for the development of low or intermediate temperature solid oxide fuel cells. Perovskite and perovskite-related materials are promising candidates on this role. In the review the conductivity and the thermal expansion of materials with various types of perovskite-related structures such as pure ...
