The Publication Ethics Statement of the Journal “Rasplavy” (document for review)

The Editorial Board of the Journal “Rasplavy” adheres to the following issues of publishing ethics:

1. Publications and authorship

• No plagiarism and/or falsified data
• The prohibition to publish the same work in more than one journal

2. Authors’ responsibility

• Authors are required to participate in the process of reviewing work
• All authors contribute to the work
• All data in the article must be true and authentic
• All authors should provide text abbreviations and correct errors

3. Reviewing, responsibility before reviewers

• Judgments of the reviewers have to be objective
• Reviewers should not have a conflict of interest with the authors of the work
• Reviewers should note important published works that were not referenced by the authors
• All articles subject to peer review, should be treated confidentially

4. Responsibility of publishers

• Publishers are fully responsible for accepting, refusing articles
• Publishers should not have a conflict of interest regarding the articles they accept / reject.
• The work is accepted if it is really reliable
• If errors were found, it is necessary to amend or reduce text
• Keep anonymity of reviewers

   5. Malpractice statement

• Malpractice – deliberate use of employee official powers contrary to the interests of his official duty, based on selfish personal interest.
• Protectionism, favoritism, nepotism in the selection of publications, as well as other malpractice on the part of the editorial board, are incompatible with the principles and standards of professional ethics.
• Depending on the type of offense resulting from malpractice in relation to the offender measures stipulated by the current legislation of the Russian Federation and local regulations may be applied, either criminal, or administrative, or civil, or disciplinary and material liability.

The editorial board strongly supports publishing ethics issues:

• ensures that articles that do not correspond to ethics are rejected for publication;
• preserves the integrity of the academic word;
• separates commercial issues and intellectual and ethical norms;
• always ready to publish additions, comments, corrections and apologies, if necessary, without plagiarism and knowingly false information.

ABSTRACT

The interaction between a solid inert metal (Ru) and an active liquid metal (Ga) on the mechanical activation in high-energy planetary mill was studied by X-ray diffraction and scanning electron microscopy with EDS-apparatus for high-resolution energy dispersion X-ray microanalysis. The influence of the regime of mechanical activation on the formation of intermetallic compounds GaxRuy and composites GaxRuy/Ru and on their solubility in concentrated acids were investigated. Gallium is a surface-active substance for ruthenium. On the mechanical activation liquid Ga penetrates at the grain boundaries of polycrystalline ruthenium particles and sharply reduces their strength. As a result of strong mechanical deformation the contact surface area between the solid and liquid metals is significantly increased, where the intermetallic compounds are intensively formed. Under the treatment by mixture of concentrated hydrochloric and nitric acids, ruthenium (~37%) from the intermetallic compounds passes into the acidic solution, forming a complex compounds HxRuCly (H2RuCl6).

KEYWORDS:

mechanochemical synthesis, intermetallic compounds, gallium, ruthenium, ruthenium complex compounds.

ABSTRACT

The interaction between a solid inert metal (Ir) and an active liquid metal (Ga) on the mechanical activation in high-energy planetary mill was studied by X-ray diffraction and scanning electron microscopy with EDS-apparatus for high-resolution energy dispersion X-ray microanalysis. The influence of the regime of mechanical activation on the formation of intermetallic compounds GaxIry and composites GaxIry/Ir and on their solubility in various acids were investigated. Gallium, being a surface-active substance for iridium, penetrates at the grain boundaries of polycrystalline iridium particles and sharply reduces their strength. Under strong mechanical deformation during activation the contact surface area between the solid and liquid metals is greatly increased, where the intermetallic compounds are intensively formed. As a result of treatment by mixture of hydrochloric and nitric acids, iridium (~30%) from the intermetallic compounds passes into the acidic solution, forming a complex compounds HxIrCly (H2IrCl6), which, interacting with bases, can give a soluble complex salts.

CON T E N T S

(18–22 September 2017, Ekaterinburg)

From 18 to 22 September the First international conference on intellect-intensive technologies in power engineering (physical chemistry and electrochemistry of molten and solid electrolytes) was held at the recreation center “Oriole”. Officially 257 people were registered at the conference, among them 150 full-time participants. About 70 scientists came from Ekaterinburg and about 80 delegates from various parts of our homeland and abroad: the Republic of Belarus, Israel, South Korea, Italy, the Netherlands, Greece and India.

Within the framework of the conference, 3 plenary sessions were held, at which 13 reports were heard on the most relevant topics of the conference. In addition, 55 key reports, 24 oral presentations, 30 youth reports and about 130 poster presentations were presented at the sections. Roundtables were held in the following areas: testing of nuclear fuel, the study of proton-conducting materials, and the study of electrode processes in electrochemical systems with solid electrolytes. It was held a two-day School for young scientists, which included a course of lectures and the contest of presentations. Young specialists attended 9 lectures on physical and chemical methods of research (Raman spectroscopy, resonance spectroscopy, neutron diffraction); lectures on the improvement of academic writing and communication skills in English; lectures on scientometric analysis in scientific activity and on numerical modeling in electrochemical systems. Within the framework of the Young Scientist Contest, 30 oral reports on 3 directions were heard where, as result, the winners in each of the areas were revealed and awarded. In addition, about 20 poster presentations were made, where one winner was determined as well.

The cultural program was intense and interesting for all participants. So, in an informal atmosphere, during the week there were an evening of grilled meat (barbeque party), billiard and bowling evening, off-site day excursions around Ekaterinburg and to the Sysert porcelain factory were arranged for the guests of the conference.

According to the results of the conference selected reports will be published in special issues of journals “Melts”, “Electrochemistry” and “Alternative Energy and Ecology”. Now a collection of reports is available for downloading (download).

In conclusion, it should be noted that the conference was very successful! The coverage of scientific fields in which the conference participants presented reports is broad and deep.

ABSTRACT:

IR-spectroscopic, X-ray diffraction studies of the initial magnesium nitrate hexahydrate, intermediate and final products of its thermal decomposition in air were carried out. Thermographic analysis made it possible to determine the main parameters and the mechanism of thermolysis of a given salt. Friedman’s analysis shows the multistage process.

KEY WORDS:

thermal decomposition, thermolysis, magnesium nitrate hexahydrate, magnesium oxide, nitrous gases IR spectroscopy, X-ray diffraction, ASTM method, Friedman analysis.
