A new method has been developed to determine the activation energy for hydrogen desorption from steels by means of thermal desorption spectrometry (TDS). This method directly fits the Kissinger’s reaction kinetic formula dX/dt=A(1-X)exp(-Ed/RT) to experimentally measured thermal desorption spectrum and best fit yields the activation energy (Ed) and the value of constant A. It has been proven that this new method is applicable to precise measurement of the activation energy for hydrogen desorption from incoherent TiC particle, coherent TiC precipitate, grain boundary and dislocation in 0.05C-0.20Ti-2.0Ni and 0.42C-0.30Ti steels.

Polarographic Current

A method for the elimination of various components of the polarographic current is proposed, based on its differentiation and/or integration with respect to time forming a linear combination of the results with the original current. A linear combination of n different functions can be used to eliminate n - 1 current components. Examples for the elimination of the charging, diffusion, and kinetic current are given, and the possibilities of realization and utilization of the new method are discussed.

A new method in perturbation theory of electromagnetic fields in metal cavity has been proposed in this paper. When a medium is introduced in metal cavity, the electromagnetic fields and oscillating frequency will be changed. The changed fields can be expanded as the fields of all modes in the original empty metal cavity. The expressions of the fields and the frequency in the various orders of approximation have been derived, that is important for such applications as the precise measurement of high permittivity of microwave materials.

This paper proposes a new method for characterization of 2D materials under the precisely specified conditions. It is achieved by integration of a 2D material as a field effect transistors structures with a piezoelectric resonator. Properties of the 2D material can be mechanically adjusted by the resonator. It results in the independent and precise control of an amplitude of induced mechanical strain, its modulating frequency, which all influence the 2D material properties. The electrical field required to measure 2D material field effect transistors will not be affected by the vibrations, thus giving us a chance to perform the precise measurement of the electrical properties of the 2D material. This approach has a great potential for measuring and monitoring cells, enzymes, nucleic acids, deoxyribonucleic acid and ribonucleic acid. It can be also used for measurement of toxic, combustive or waste gases.
