We find the analytical expression for the residual entropy of the square Ising model with nearest-neighbour antiferromagnetic coupling J, in the maximum critical field H-c = 4J, in terms of the Fibonacci matrix, which ...

The cold solution of a pyrophosphate kit was prepared and dispensed into 2-ml fractions which were stored at -20 degrees C for one week. The solution was prepared by using two protection methods. The first was nitrogen ...

Mechanical activation of CeO2-ZrO2-SiO2 mixtures was performed in a high energetic vibratory mill with WC lining and grinding media. It was shown that in air atmosphere the reduction of Ce4+ into Ce3+ took place at 1400 ...

Data on mechanochemical synthesis of PbTiO3 from PbO and TiO2 without subsequent heating of activated mixtures are presented. Physical and chemical processes occurring during mechanical activation are followed by the X-ray ...

A new diiodine substituted LDA derivative, 2,4-diiodine-6-methyl IDA (DIIODIDA) was synthesized and labeled with Tc-99m. It was established that Tc-99m-DIIODIDA had high radiochemical purity. Biodistribution and influence ...

For arbitrary wave propagation angle with respect to the magnetic field the wave cutoff and in particular, its dependence on the particle temperature are investigated. The obtained results demonstrate that when the wave ...

The Fokker Planck equation was used to analyze the probability of the appearance of radionuclide impulses of any type. Distribution functions for the stationary state and conditions when different factors influence the ...

Unidirectional signal detection in time-resolved rotational anisotropy experiments has been known to affect the time zero and time infinity (persistent alignment) values because these measurements can overestimate the ...
