Ion-selective electrodes (ISEs) with membranes based on ion exchangers plasticized with o-nitrophenyl octyl ether (NPOE), diethyl sebacate (DES), or dibutyl phthalate (DBP) are used for the determination of ionic liquids (ILs) in water. The membrane composition is optimized with respect to the ion-exchanger concentration and the plasticizer. 相似文献

The motion of a heavy Brownian particle in a low-dimensional bounded solid structure under the effect of a phonon’s excitation
fluctuations is considered. Because of the finiteness of the system, the fluctuation spectrum has zero spectral density at
zero frequency. The effect of this kind of noise, which is conditionally called “green” noise, is studied both analytically
by using the averaging method and numerically on the basis of predictor-corrector algorithms. The effective potential is introduced,
and its form is shown to govern the particle dynamics. Considering a Gaussian potential well (a trap) as an example, it is
demonstrated that green noise leads to abrupt phase transitions in the system as a result of very small parameter variations
(a catastrophe-type effect). The results are compared with the case of white noise in an unbounded structure. From numerical
calculations, it follows that the boundedness of the structure, which changes the noise spectrum, favors a considerable increase
in the lifetime of the particle in the trap. 相似文献

We report on double-differential inclusive cross-sections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% λ int thick stationary lead target, of proton and pion beams with momentum from ±3 GeV/c to ±15 GeV/c. Results are given for secondary particles with production angles 20°<θ<125°. Cross-sections on lead nuclei are compared with cross-sections on beryllium, copper, and tantalum nuclei. 相似文献

The paper deals with the problem of constructing systems with discontinuous quasizero reconstructing force on the basis of structures where an elastic element moves between two directrices of prescribed design shape perpendicularly to their axis of symmetry. A spring is considered as an elastic element. The cases where the elastic element works only in compression or only in tension are considered. 相似文献

Hadron generation in the Geant4 simulation tool kit is compared with inclusive spectra of secondary protons and pions from
the interactions with beryllium nuclei of +8.9 GeV/c protons and pions, and of −8.0 GeV/c pions. The data were taken in 2002 at the CERN Proton Synchrotron with the HARP spectrometer. We report on significant disagreements
between data and Monte Carlo simulation especially in the polar-angle distributions of secondary protons and pions.

The structural relaxation of a bulk Pd40Cu30Ni10P20 metallic glass is studied by measuring the electrical resistivity and infralow-frequency (0.05 Hz) internal friction. It is demonstrated that the structural relaxation in thermally aged samples can be restored by quenching them from a supercooled liquid state. It is found that the degree of relaxation after quenching can exceed the initial one by several times. 相似文献
