The crystal structures of complex antimony(III) fluorides RbSbF4 (I) and (C2N4H5)SbF4 (II) were determined. The crystals of I and II are monoclinic; for I: a = 4.628(1) Å, b = 6.167(1) Å, c = 7.922(1) Å, = 100.582(3)°, V = 222.24(7) Å3, Z = 2, (calcd.) = 4.23 g/cm3, (exp.) = 4.25 g/cm3, F(000) = 248, space group P21/m, R = 0.0395; for II: a = 4.678(1) Å, b = 7.339(4) Å, c = 10.185(1) Å, = 90.88(2)°, V = 349.6(2) Å3, Z = 2, (calcd.) = 2.69 g/cm3, (exp.) = 2.70 g/cm3, F(000) = 264, space group P21. The structure of I is formed by Rb+ cations and [SbF4]

anionic chains composed of SbF5E octahedra with two bridging fluorine atoms. The structure of IIis formed by (C2N4H5)+ cations and isolated [SbF4]– anions in which the antimony polyhedra are SbF4E trigonal bipyramids. The relationship between the crystal structures and electrophysical and biological properties of single-charged cation tetrafluoroantimonates(III) was studied. 相似文献

A comparative analysis of various models of exponentially correlated random fields associated with Poisson point ensembles
is given. Algorithms for the modeling of radiative transfer in random media of this type are considered. An asymptotic estimate
for the particle passage probability is constructed assuming that the flow of trajectory intersections with domains of constant
random density is Poisson distributed. 相似文献

Cyclotron-resonance measurements in 21-nm-thick HgTe/CdHgTe quantum wells of different crystallographic orientations have been performed. It has been found that, in contrast to the structures with the (001) orientation of the quantum-well plane, (013)-oriented quantum wells are semimetallic and their absorption spectra exhibit both electron and hole cyclotron-resonance lines. The simultaneous presence of the two types of charge carriers originates from an overlap between the upper heavy-hole quantum-confinement subbands hh1 and hh2. This overlap is caused by the strong interaction of these subbands with the Dyakonov-Khaetskii interface state. Calculations carried out using the eight-band kp-Hamiltonian indicate that, for known values of the band-structure parameters, the overlap between hh2 and hh1 subbands does not occur; this result is in agreement with the cyclotron-resonance data for (001)-oriented structures. The enhanced interaction between heavy-hole and interface states owing to the existence of steps at low-symmetry heterointerfaces may be the mechanism responsible for the appearance of an overlap between subbands in HgTe quantum wells with orientation different from (001). 相似文献

The formation of periodical structures, and also, micro- and nanoparticles on a polycrystalline magnesium and aluminum surface
under high power proton-carbon beam irradiation has been investigated. The spatial parameters of these structures and particle
sizes have been determined. The possible mechanisms for periodical structure formation have been considered. 相似文献

New composite lignocellulose materials were prepared using modified lignin and nanocellulose. The materials were studied by elemental and thermal gravimetric analysis, and their tensile tests were performed. The results obtained show that addition of nanocellulose to modified lignin makes possible its use as filler in paper production. 相似文献
