Using additional standards for increasing the accuracy of quantitative chromatographic analysis

Autor: Igor G. Zenkevich, D. V. Prokof’ev

Publikováno v: Journal of Analytical Chemistry. 72:510-519

Uncontrolled partial losses at the step of sample injection into a gas chromatographic column increase errors of determination by the external standard, absolute calibration, and standard addition methods. Modified method is proposed for quantitative

Autor: V. A. Seredkin, V. S. Zhigalov, Irina S. Edelman, Sergey M. Zharkov, G. N. Bondarenko, D. E. Prokof’ev, G. I. Frolov, R. D. Ivantsov

Publikováno v: Physics of the Solid State. 50:2109-2114

The magnetic properties and magneto-optical effects in nanocomposites based on Co-Sm-O films prepared through pulsed plasma sputtering of a SmCo5 target are investigated. It is shown that, depending on the technological conditions and regimes of subs

Distribution of the magnetic field induced by a current passing through slabs in the superconducting and normal states

Autor: D. D. Prokof’ev

Publikováno v: Technical Physics. 51:675-682

The magnetic field induced by a current passing through a long slab is calculated. For the uniformly distributed current, simple formulas for the field components inside and outside the slab are derived. For the nonuniformly distributed current, the

Pseudogap and its temperature dependence in YBCO from the data of resistance measurements

Autor: M. P. Volkov, Yu. A. Boikov, D. D. Prokof’ev

Publikováno v: Physics of the Solid State. 45:1223-1232

The temperature dependence of the excess conductivity Δσ for Δσ = A(1 − T/T *)exp(Δ*/T) (YBCO) epitaxial films is analyzed. The excess conductivity is determined from the difference between the normal resistance extrapolated to the low-tempera
