Black single crystals of Ta(4)Se(9)I(8) are obtained in a high yield by heating Ta, Se, and I(2) at 300 degrees C in 1:2.2:1.0 molar ratio. In the structure, the tantalum atoms form a square, with four Se(2) ligands bridging the Ta-Ta edges and one capping the square. Each Ta atom has two terminal iodine atoms. The compound is diamagnetic and has only two electrons for metal-metal bonding. 相似文献

The polarization observables Σ,P y ,T 1,P y ⊥ ,P y ∥ are derived in proton polarization measurements of the \(\vec \gamma d \to \vec pn\) reaction, using a linearly polarized photon beam of energies between 300 and 600 MeV for c.m.s. proton emission angles of 90° and 120°. A multipole analysis is performed in the framework of the gauge-invariant pole model considering theγN→πN amplitudes and the deuteron structure without dibaryon resonances and with different sets of isovector and isoscalar dibaryon resonances. It is shown that the inclusion of dibaryon resonances substantially improves agreement with experimental data. 相似文献

The processes of degradation of 2,4-dichlorophenol (2,4-DCP) aqueous solutions under the action of atmospheric pressure of DBD in oxygen were studied. The degradation of 2,4-DCP proceeds efficiently, the degree of decomposition reaching 100%. The degradation kinetics of 2,4-DCP obeys a formal first-order kinetic law on concentration of 2,4-DCP. The effective rate constants depend weakly on the experimental conditions and are equal to ~ 2 s?1. Based on experimental data, the energy efficiency of 2,4-DCP decomposition was determined to be in the range of 0.039–0.173 molecules per 100 eV depending on the experimental conditions. The composition of the products was studied by gas chromatography, chromatography-mass spectrometry, UV/visible spectroscopy, fluorescent methods and some chemical methods. The main decomposition products present in the solution were found to be carboxylic acids, aldehydes and chloride ions, whereas carbon dioxide and molecular chlorine appear in the gas. The results obtained are compared with similar data from other advanced oxidation processes (AOP’s) methods. 相似文献

A method of resonant near-field microwave probing is developed for contactless diagnostics of a high-pressure plasma. The
efficiency of this method in measuring the parameters of the plasma of an rf capacitive discharge in argon under atmospheric
pressure is demonstrated. The experimental results are compared with the data obtained using the independent method, the microwave
radiation “cutoff,” and with theoretical estimates. 相似文献

The known phosphonium chloride [HO(Me)CH]4PCl was prepared at ambient conditions from PH3 and acetaldehyde in aqueous HCl, and characterized by elemental analysis and 1H and 31{1H} NMR spectroscopy. Attempts to obtain the tertiary phosphine [HO(Me)CH]3P via reaction of [HO(Me)CH]4PCl with Na2SO3 or Et3N in aqueous media under Ar revealed that [HO(Me)CH]3P is unstable and equilibrates with the secondary phosphine [HO(Me)CH]2PH and acetaldehyde. A 1:4 reaction of [HO(Me)CH]4PCl with NaHSO3 at room temperature under Ar affords first the oxide [HO(Me)CH]2P(O)H and then the phosphinic acid [HO(Me)CH]2P(O)OH. A 1:1 reaction of [HO(Me)CH]4PCl with Na2S2O3 affords the sulfide [HO(Me)CH]3PS. 31{1H} and 1H NMR data for all the (α-hydroxyethyl)phosphorus species are reported for the first time. 相似文献

Results of study of the $K^ - \to \pi ^0 e^ - \overline \nu \gamma $ decay at the ISTRA+ setup are presented. We observed 4476 events of this decay. The branching ratio is found to be $R = \frac{{Br(K^ - \to \pi ^0 e^ - \overline \nu _e \gamma )}}{{Br(K^ - \to \pi ^0 e^ - \overline \nu _e )}}$ = (1.81±0.03(stat.)±0.07(syst.)) × 10?2 for E*γ > 10 MeV and θ*eγ > 10°. For comparison with the previous experiment the branching ratio with cuts E*γ > 10 MeV, 0.6 < cos θ*eγ < 0.9 is calculated: R = $\frac{{Br(K^ - \to \pi ^0 e^ - \overline \nu _e \gamma )}}{{Br(K^ - \to \pi ^0 e^ - \overline \nu _e )}}$ = (0.47±0.02(stat.) ± 0.03(syst.)) × 10?2. For the cuts E*γ > 30 MeV and θ*eγ > 20°, used in most theoretical papers, Br = (3.06 ± 0.09(stat.) ± 0.14(syst.)) × 10?4. For the asymmetry we get A ξ = ?0.015 ± 0.021. At present it is the best estimate of this asymmetry. 相似文献
