Preparation of prolonged-action antimicrobial polymeric films based on polyvinyl alcohol and carboxymethyl cellulose sodium salt (Na-CMC), modified with chlorohexidine, is studied. The effects of Na-CMC on the adsorption capacity, degradability, and specific weight of the electrodeposited film are examined. 相似文献

The reactions between [Mo3(μ3-S)(μ2-S)3(Acac)3(Py)3]PF6 (HAcac is acetylacetone, Py is pyridine) and CuX (X = Cl, I, SCN) afford heterometallic cubane clusters [Mo3(CuX)(μ3-S)4(Acac)3(Py)3]PF6. The structures of two new compounds, [Mo3(CuCl)S4(Acac)3(Py)3]PF6 · 3.25CH2Cl2 · 0.5C6H5CH3 and [Mo3(CuI)S4(Acac)3(Py)3]PF6 · 4C6H6, are determined by X-ray diffraction analysis. All synthesized compounds are characterized by elemental analysis and IR spectra. According to the vibrational spectra, the thiocyanate complex in the solid state is a mixture of the bond isomers [Mo3(CuNCS)S4(Acac)3(Py)3]PF6 and [Mo3(CuSCN)S4(Acac)3(Py)3]PF6, whereas in solution this complex exists as a isothiocyanate form. 相似文献

New supramolecular adducts of cucurbit[6]uril with triangular cluster chloroaquacomplexes of Mo and W with mixed sulfido-selenido
bridging ligands, {[W3S3Se(H2O)7Cl2]2(C36H36N24O12)}Cl2·15H2O (1), {[W3S1.5Se2.5Cl1.5(H2O)7.5]2(C36H36N24O12)}Cl5·18.5H2O (2), and {[Mo3SSe3(H2O)7.5Cl1.5]2× (C36H36N24O12)}Cl5·11H2O (3) are obtained treating the mixture of products in Mo-S-Se-Br and W-S-Se-Br systems, isolated, and structurally characterized.
In all compounds, the supramolecular structure is based on hydrogen bonded associates of cucurbit[6]uril molecule with two

B. Sturmfels modified Viro's "patchworking" method and applied it for construction of complete intersections. In the paper, this modification is used for construction of decomposable curves. 11 new arrangements of an M-cubic and an M-quartic with 12 common points lying on the odd branch of the cubic and an oval of the quartic are realized.

The reactions of the oxalate complexes [M3Q7(C2O4)3]2− (M = Mo or W; Q = S or Se) with MnII, CoII, NiII, and CuII aqua and ethylenediamine complexes in aqueous and aqueous ethanolic solutions were studied. The previously unknown heterometallic
complexes [Mo3Se7(C2O4)3Ni(H2O)5]·3.5H2O (1) and K3{[Cu(en)2H2O]([Mo3S7(ox)3]2Br)}·5.5H2O (2) were synthesized. In these complexes, the oxalate clusters serve as monodentate ligands. The K(H2en)2[W3S7(C2O4)3]2Br·4H2O salt (3) was isolated from solutions containing CoII, NiII, or CuII aqua complexes and ethylenediamine. The reaction of [Mo3Se7(C2O4)3]2− with HBr produced the bromide complex [Mo3Se7Br6]2−, which was isolated as (Bu4N)2[Mo3Se7Br6] (4). Complexes 1–3 were characterized by X-ray diffraction, IR spectra, and elemental analysis. The formation of 4 was detected by electrospray mass spectrometry.

Pentavalent bis(triorganosiloxy)triphenylantimony derivatives, Ph3Sb(OSiR3)2 (R = Me, Ph), were synthesized by reaction of triphenylantimony with trimethyl- or triphenylsilanol in the presence of tert-butylhydroperoxide by the mild reaction conditions (0-5 °C, 2 h). The reaction of triphenylantimony with diethanolamine in the presence of tert-butylhydroperoxide gave the cyclic compound Ph3Sb(OCH2CH2)2NH. The mixture of Ph3SbO and Ph3Sb(OCH2CH2NMe2)2 was obtained by the reaction of triphenylantimony with 2-(N,N-dimethylamino)ethanol in the presence of tert-butylhydroperoxide. 相似文献

The results of experiments studying the propagation of a high-frequency whistler wave in a magnetized plasma duct in the presence of an intense low-frequency wave also related to the whistler frequency range are reported. Amplitude-frequency modulation of the high-frequency whistler wave trapped in the duct was observed. A deep amplitude modulation of the signal that can lead to its splitting into separate wave packets is observed. It is shown that an increase in the wave propagation path leads to a broadening of the wave frequency spectrum and to a shift of the signal spectrum predominantly toward the red side. The transformation of the frequency of the high-frequency wave is related with the time-dependent perturbation of the external magnetic field by the field of the low-frequency whistler wave (the relative perturbation of the magnetic field δB/B≤5×10?2). 相似文献
