Methods were developed for the synthesis of 2-butylthio-2-oxo-1,3,2-oxazaphosphorinane, 2-butylthio-2-thioxo-1,3,2-dioxaphosphorinane, and 2-butylthio-2-thioxo-1,3,2-diazaphosphorinane, as well as of acyclicS-butylO-ethyl (diethylamido)phosphorothioates and-dithioates andS-butyl bis(diethylamido)phosphorodithioate. These compounds can serve as models of possible metabolites of cyclic compounds. Based on the data obtained in studies of the antiesterase activity of the resulting compounds and their synergistic activity in mixtures with permethrine, a possible mechanism ofin vitro andin vivo biological action of diheteraphosphorinanes was proposed. 相似文献

The discrete sources method (DSM) is applied to calculate light scattering by a half-spherical bubble in water on a substrate. For the first time an algorithm which allows the near-field calculation on the base of DSM is presented. Such investigations are important in immersion lithography, as the presence of bubbles on a resist surface decreases image quality. On the base of DSM the numerical algorithm of the near-field calculation is realized. Numerical results for the near-field inside the resist for different depths under the surface are presented. 相似文献

In practical applications a precise and fast detection of the shape of a single erythrocyte from its scattering characteristics is needed. For this reason detailed investigations of light scattering properties of erythrocyte and their relation to shape is of great interest in recent years. In this paper we analyze light scattering behavior of different shape models of erythrocyte using the discrete sources method. For this we compare scattering results for oblate spheroid, disk-sphere, Cassini-based shape and a shape for a real strainless erythrocyte introduced by Skalak. Numerical results for the scattering indicatrix and the differential cross section by different shape models and its orientations are presented. 相似文献

The structural and phase transitions in the nanocrystalline supersaturated α-Fe(Pb) solid solution as a result of the thermally induced transition from a highly strained state to equilibrium have been investigated by differential scanning calorimetry, X-ray diffraction, and Mössbauer spectroscopy. Two stages of structural evolution are established. 相似文献

Crystals of CaF2: Cu (with a copper impurity content higher than 0.1 at. %) grown by the Czochralski method from a melt in a mixed helium-fluorine atmosphere are investigated using electron paramagnetic resonance (EPR) spectroscopy. It is found that the crystals contain paramagnetic centers whose magnetic properties at low temperatures are identical to those of [CuF4F4]6? (S=1/2) single centers. The magnetic properties of the centers exhibit a qualitative change in the temperature range 77–300 K. These changes are described within a model according to which the center is treated as a cluster composed of three [CuF4F4]6? impurity complexes involved in exchange interactions and interactions occurring in the field of Jahn-Teller lattice distortions. 相似文献

The absorption and fluorescence spectra and the lasing ability of aminocoumarin derivatives in thin polymer layers (0.5–0.8
μm) based on the copolymer methylmethacrylate with a methacrylic acid and the copolymer methylmethacrylate with glycidylmethacrylate
formed by coating of optically transparent glass substrates have been studied. It is found that the intensity of absorption
and luminescence as well as the lasing resource of coumarins are determined by the structure of the latter and by the nature
of the polymer medium. Compositions based on the copolymer methylmethacrylate with glycidylmethacrylate and aminocoumarin
derivatives with a fluorized methyl group at the 4th molecular position can be of interest in optical technologies (light
transformers, amplifiers).

Electronic paramagnetic resonance (EPR) spectra of a GdMnO3 single crystal and GdMnO3/LaAlO3 thin film have been measured at X- and Q-band frequencies in the temperature range from 4.2 to 300 K. It is found that the EPR spectrum of a GdMnO3 single crystal consists of only one broad exchange-narrowed line. Unusual magnetism is observed at the interface between the GdMnO3 thin film and LaAlO3 substrate, where it is possible to see the fine structure of the EPR spectrum for a Gd3+ ion. The parameters characterizing the fine structure related to the Gd3+ ion in the GdMnO3 film deposited onto the LaAlO3 substrate are determined. 相似文献

Lanthanum-strontium manganites doped with zinc are studied by the method of electron magnetic resonance. Nano-objects with ferromagnetically correlated spins, which behave themselves like superparamagnetic particles in the magnetic resonance spectrum, have been found in the paramagnetic phase. The temperature dependences of the resonance magnetic field and magnetic resonance linewidth for La1 ? x Sr x Mn0.925Zn0.075O3 ceramic samples at temperatures ranging from 100 to 340 K have been analyzed on the basis of the Raikher-Stepanov theory of superparamagnetic particles. The magnetic moment, anisotropy field, and characteristic size of the regions of the ferromagnetically correlated spins have been determined. 相似文献
