Novel mononuclear cymantrenecarboxylate complexes of transition metals, [Co(H2O)6](CymCO2)2·4H2O (Cym = (η5-C5H4)Mn(CO)3) (1), [Ni(H2O)6](CymCO2)2·4H2O (2), [Zn(H2O)6](CymCO2)2·4H2O (3), [Co(CymCO2)2(imz)2] (imz = imidazole, 4), [Co(CymCO2)2(bpy)2]·2PhMe (bpy = 2,2′-bipyridyl, 5), [Ni(CymCO2)(bpy)2(H2O)][CymCO2]·0.5MePh·2H2O (6), [Cu(CymCO2)2(imz)2] (7), and [Cu(CymCO2)2(bpy)(H2O)] (8), were obtained and characterized by single-crystal X-ray analysis. Complexes 1–3 are isostructural. Magnetism of the Co complexes 1, 4, and 5 was studied; it was shown that they exhibit the properties of field-induced single-molecule magnets with magnetization reversal barriers (ΔE/kB) of 44, 13, and 10 K, respectively. Thermal decomposition of complexes 1–8 was studied by means of DSC and TGA methods. The final products of thermolysis of 1–6 in air, according to powder XRD data, are the pure spinel phases MMn2O4; for the cases of copper complexes, the mixtures of CuMn2O4 and CuO were found in the products. 相似文献

The influence of self-and cross-phase modulation on third-harmonic generation in a hollow waveguide is investigated. Analytic
solutions of the coupled equations for the slowly varying amplitudes of the pump pulse and the third harmonic in a gas-filled
hollow waveguide are obtained with consideration of self-and cross-phase modulation and first-order dispersion effects. The
possibility of controlling the nonlinear phase trajectory of the third harmonic by cross-phase modulation is demonstrated.

An experimental investigation of sedimentation of single particles and concentrated suspensions in Couette flows of viscous
and viscoelastic fluids is presented. With the passage from viscous to viscoelastic fluids, a slowing down of the sedimentation
was observed. The sedimentation of suspensions in viscoelastic fluids accelerated with increase in the suspension concentration.
The development of instabilities during the sedimentation was detected. 相似文献

Plane nonlinear fluid flows through a porous medium which simulate a sink located at the same distance from the roof and floor of the stratum for two nonlinear flow laws are constructed. The following flow laws are taken: a power law and a law of special form reducing to analytic functions in the hodograph plane. 相似文献

The reactivity of dihydroquercetin and catechol flavonoids in acylation, phosphorylation, and aminomethylation reactions was compared. The structure of natural polyatomic phenols was shown to affect markedly their chemical behavior. 相似文献
