Polycrystalline hydroxyapatites Ca(10-x)REE(x)(PO(4))(6)(OH)(2-x)O(x) were synthesized and studied by X-ray powder diffraction, infrared absorption, diffuse-reflectance spectroscopy, thermogravimetry. The solubility limits x(max) of rare earth elements (REE) in Ca decreases with an increasing REE atomic number from = 2.00 for La, Pr, Nd to 0.20 Yb at 1100 °C. Refinements diffraction patterns the Rietveld method show that atoms substitute preferentially Ca(2) sites apatite structure....
The magnetic-field dependence of the oscillation amplitude magnetization two-dimensional electron gas is studied both analytically and numerically. A closed analytical expression for envelope oscillations obtained in limit sharp Landau levels.
We derive an analytical expression for the size distribution of monoatomic wires in framework a one-dimensional lattice gas model at thermodynamic equilibrium. The theoretical results are compared with Ag obtained via nucleation step edges $\mathrm{Pt}(997)$ surface.
It is shown that the strain field of an edge dislocation in a smectic crystal must be described framework nonlinear theory, even far away from core region. We present exact solution this problem. The result linear theory recovered limit large bending rigidity.
The low-temperature electron spin resonance (ESR) spectra and the static magnetization data obtained for stoichiometric single crystals of $\ensuremath{\beta}\ensuremath{-}{\mathrm{Na}}_{0.33}{\mathrm{V}}_{2}{\mathrm{O}}_{5}$ indicate that this quasi-one-dimensional mixed-valence compound demonstrates at ${T}_{N}=22 \mathrm{K}$ phase transition into canted antiferromagnetically ordered state. spontaneous $3.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ ${\ensuremath{\mu}}_{B}$...
The kinetics of the nucleation and growth a new phase in course first-order transition solid is described. growing center very oblate, because this shape lowers elastic energy deformations which arise due to difference densities two phases. An analogy with crack problem emphasized. nucleus governed by combination effects diffusion latent heat. cracklike lead selection mode substantially different from ordinary dendrite.
We consider a sharp interface kinetic model of phase transitions accompanied by elastic strain, together with its phase-field realization. Quantitative results for the steady-state growth new in strip geometry are obtained, and different pattern formation processes this system investigated.
On the basis of working research WWR-M reactor at PNPI there is being built a highly intensive source ultracold neutrons (UCN) and very cold (VCN) for scientific in fundamental physics investigation nanoparticles. The will use superfluid helium that allow us to obtain density 104 cm-3, which approximately 1000 times exceeds available neutron existing UCN sources.
$^{7}\mathrm{Li}$ NMR spectra were measured in a magnetic field up to 17 T at temperatures 5--30 K on single crystalline ${\mathrm{LiCu}}_{2}{\mathrm{O}}_{2}$. Earlier reported anomalies magnetization curves correspond values where we observe changes of the spectral shape. For interpretation and temperature evolutions our spectra, structures analyzed frame phenomenological theoretical approach Dzyaloshinskii-Landau theory. A set possible planar collinear was obtained. Most these have an...
The surface of a propagating crack is shown to be morphologically unstable because the nonhydrostatic stresses near (Asaro-Tiller-Grinfeld instability). We find that energy wavy becomes smaller than straight if length few times larger Griffith length. local dispersion relation derived assuming instability develops via mass transport by diffusion. also argue widely used condition vanishing ${K}_{\mathrm{II}}$, stress-intensity factor sliding mode, appears in natural way our description as an...
We discuss the coarsening process of melt inclusions inside a solid phase. Elastic effects lead to an oblate shape particles, resulting in system with strong diffusional and elastic interactions between inclusions. The usual mean-field approximation breaks down several independent length scales have be taken into account. In parallel oriented particles we find scaling laws for different involved. particular, lateral size obeys nontrivial growth law, R approximately t(5/12).
