Crystal chemical properties of lanthanide oxochlorotungstates of composition LnWO4Cl (Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm) are reported. The unit cell parameters a, b, c, c′, and V of the LnWO4Cl compounds are correlated with lanthanide ionic radii from different radius systems and with the lanthanide atomic number. The ionic radius systems most suitable for describing the crystal chemical properties of the lanthanide oxochlorotungstates are determined. 相似文献

LCAO MO SCF calculations using the 3-21G basis were used to study the electronic and three-dimensional structure of several
polycyclic aromatic hydrocarbons as models for the surface of activated charcoal. Localized carbon-carbon double bonds capable
of adding electrophilic reagents were found on the periphery of these molecules. The reactivity of the peripheral C=C bonds
was evaluated relative to consecutive bromination reactions of the C54H18 molecule.

A facility is described that allows safe handling of high tritium gas activity as dozens kilocuries in a regular laboratory
environment. It is used to make and deliver into the target a mixture of specific isotopic composition with the contamination
requirement of 10-7 v.f. for Z>1 elements, and recover it upon completion of operation. With this facility, efforts have been accomplished to investigate
into the muon catalyzed fusion on two targets – liquid tritium and high-pressure tritium types. Also, the operation range
was 0.1–120 MPa for pressure and 20–800 K for temperature and the amount of tritium used was about 100 kCi. The facility showed
reliability in operation without indications of radiation beyond the safety level.

A new method of 2D periodic lattices excitation in quadratically nonlinear media with cascade interaction is suggested. It
is shown that in such structures the all-optical management of laser beams could be carried out. The possibility of switching
waveguides and changing the final energy distribution among channels using the phenomenon of discrete diffraction is demonstrated. 相似文献

The recent papers that consider new effects attributed to the total refection of a weak beam at a more powerful beam with
another frequency in nonlinear media are reviewed. As an example, the dynamics of the beam reflection in media with thermal
nonlinearity and photorefractive crystals are analyzed. 相似文献

The effect of a frequency shift and time delay during the cascade parametric interaction of a weak signal pulse with a high
powered reference pulse is demonstrated for the first time. The conditions of total reflection of a pulse signal in a crystal
with quadratic nonlinearity are found. The equation for the frequency shift of a reflected wave is derived. 相似文献

The adsorption of phenylethylamine, tryptamine, and tyramine on carbon nanotubes from aqueous solutions (pH 7.4) was studied
depending on time and sorbate concentration. The suggestion was made that their interaction with electrodes was determined
by electrostatic attraction between protonated amino groups and oxygen-containing functional groups of the surface of carbon.
An increase in the adsorption of biological amines was caused by the interaction of the π systems of their aromatic rings with carbon surface hexagons. The adsorption of biogenic amines on carbon nanotubes was necessary
for their possible electrooxidation and analytic determination by electrochemical methods with the use of carbon electrodes.

The product composition and the principles of photochemical transformations of tetrahexylammonium tetrachlorocuprate [(RH)4N+]2[CuIICl4]2− (RH = C6H13) in 2-chlorobutane at 77 K have been found out by ESR spectroscopy. It has been shown that the photolysis of [(RH)4N+]2 [CuIICl4]2− results in the formation of alkyl radicals (R⊙), presumably, anions [CuICl3]2− and organic copper(II) compounds {CuIIR}. A reduction in the quantum yield of primary photolysis products during the reaction, nonequivalence of the quantum yield
of the buildup of paramagnetic photolysis products to that of [CuIICl4]2− consumption, and a decrease in the total number of paramagnetic particles in the system during the photolysis have been revealed.
A photolysis mechanism involving both photochemical and thermal processes is proposed. 相似文献
