Carbon target as neutron source from 12C(d,n)13N and D(d,n)3He reactions
No full textPossibility to use carbon as a target material to generate fast neutrons from D(d,n)3He nuclear reaction and intermediate energy neutrons from 12C(d,n)13N nuclear reaction was studied. The experiment results were obtained to characterize an adsorption of the deuterium while stuffing the carbon target by beam of accelerated ions and a desorption of the deuterium from the same carbon target as the function of its temperature. Bombardment of carbon target with 400 keV deuteron beam of 1 mA current leads to the 12C(d,n)13N nuclear reaction, allowing to generate neutrons of (10 ÷ 100) keV energy range with neutron flux density (106 - 107) n/(cm2·s) near the carbon target

No full textContext. The problem of data depersonalization in information systems is considered. The analysis of modern approaches to depersonalization of data is carried out, it is revealed and proved by need of creation of the new method allowing to increase security of the processed data and their reliability. The object of the study was a model of data depersonalization, allowing to reduce the cost of protecting information systems. Objective. The goal of the work is the analysis of modern methods of depersonalization and the creation of a method that eliminates the identified shortcomings, with an increased level of confidentiality and use of hashing of critical data and a private key.Method. A method of personal data depersonalization is proposed, based on the method of entering identifiers using hashing of critical data and a private key, which allows to increase the confidentiality of information processed in information systems. Methods are proposed for selecting key critical attributes from primary documents that uniquely identify the subject of personal data, the method of generating initial sets, which divides the source data into two disjoint subsets, the method of generating a hash identifier from a unique sequence and a private key that depersonalizes information and enhances its confidentiality.Results. The developed method is implemented in software and researched while solving the problems of depersonalization.Conclusions. The carried out experiments confirmed the efficiency of the proposed method and allow to recommend it for implementation in automated information systems for processing personal data for solving problems of depersonalization. Prospects for further research may be in the creation of hardware streamlined data depersonalization allowing to increase the speed of processing and confidentiality of data in the information systems.

Enabling exciton tuning in nanostructured EuOx films by plasma-based synthesis in vacuum
No full text2017 MRS Fall Meeting & Exhibit, Boston, Massachusetts, November 26 - December 1, 2017. -- https://www.mrs.org/fall2017Due to its room temperature band-gap of 1.12 eV in bulk configuration [1] and to its compatibility with the technologically relevant semiconductors Si, GaAs and GaN [2][3], Europium monoxide (EuO) is a promising ferromagnetic semiconductor for the development of integrated spintronics and optical devices [4] . . However, EuO is highly unstable and tends to transform to the more stable Eu2O3. For this reason its synthesis with a suitable stoichiometry is challenging, and usually costly deposition techniques such as molecular beam epitaxy are employed [4]. This has hindered a widespread use of this relevant semiconductor, and its optical response and potential upon nanostructuration have been to-date scarcely investigated and exploited [5].
In this work we report the successful preparation of nanostructured EuOx thin films by a plasma based technique (pulsed laser deposition, PLD) using a non-conventional approach that consists in the in-situ reduction of a Eu2O3 bulk ceramic target by deposition in vacuum (10-7 mbar). Remarkably, our method allows achieving a fine-tuning of the oxygen content in the synthetized films by controlling the vacuum pressure in the chamber during the laser plasma generation. We demonstrate that the full range of film composition tuning: from EuO to Eu2O3 has been obtained. X-ray diffraction measurements show that the films are highly textured and are formed by nanocrystal grains with size in the 10 nm range. Spectroscopic ellipsometry measurements in the UV-VIS have been used to determine the nanostructured films band-gap and the magnetic exciton absorption values. Stoichiometric EuO films show properties similar to those of bulk EuO single crystals, however with a blue shift related to the stressed nanocrystalline structure. Further shift of the absorption edge to higher energies is achieved by increasing the oxygen content in the films. This successful plasma-reduction synthesis can be extrapolated to other plasma-based techniques, opening an inexpensive route for the synthesis of EuO as well as for other active functional oxides.
