In the short historical essay, the ways of formation of Materials Science in Ukraine are considered, and tendencies of its development over the World were taken into account. The outstanding human resources and excellent raw deposit capabilities of Ukraine have led to creating Ukrainian scientific schools back in the days of the Russian Empire, which were comparable to the Ural and another world schools of metallurgists and metal scientists. The further development of science on materials in Ukraine is closely related with establishing the Academy of Sciences in 1918. From the first twelve members of the All-Ukrainian Academy of Sciences, three of them namely V.I. Vernadsky, P.A. Tutkovsky and S.P. Tymoshenko, had represented the natural sciences. The election of E.O. Paton to the Academy in 1929 for "technical sciences" specialty had initiated the usage of promising achievements of fundamental sciences for development of applied ones. Since that, the famous Institutes of Ferrous Metallurgy (1936), Metal Ceramics and Special Alloys (1955) and others were founded. The idea to develop the new area of knowledge, which would combine the different types of interatomic bonding to be resulted in new materials and would not be preferable to metallic materials only, has been already in time, namely in 1963. B.Ye. Paton jointly with I.M. Frantcevych had created the Department of Physical and Technical Problems of Materials Science, which included a few institutes namely: electric welding (Paton Welding Institute, PWI), cermets and special alloys (Institute for Problems of Materials Science (IPMS since 1964), foundry (problems of casting since 1964, and Institute of Physics and Technology Metals and Alloys (PTIMA since 1996), mechanical engineering and automation (Institute of Physics and Mechanics (IPM since 1964). And although the institutions are quite different in their profiles, their uniting direction is materials science. As early as 1963, V.N. Yeremenko was elected as the first academician for the "materials science” specialty. Therefore, the issue of a new collection of scientific papers under the title "Progress in Materials Science" is natural and vitally required. It is corresponding to global trends in the formation of scientific and technical priorities in developed countries and is as the task for Ukraine too.

The article is devoted to the development problems of the X-ray Photoelectron Spectroscopy (XPS) method in Ukraine. XPS is a modern method for studying the electronic structure of atoms. The XPS method is used at all stages of the synthesis and study of materials, the functional properties of which are determined by the state of the surface or interphase boundaries, charge states of atoms and the type of functional groups, and material degradation processes. The objects of study are catalysts, coatings, chemical sensors, sorbents, coordination and organometallic compounds (chemistry, materials science, phar­maceuticals), surface condition and composition (microelectronics), thin films (optics), alloys (aviation and space industry), nanopowders, nanofilms (nanotechnology). The method is relevant for the implementation of targeted synthesis of materials. In the world, the XPS method is widespread and integrated into innovative branches of science and technology, and XPS - instrumentation - is a high-tech business. In Ukraine, the method is practically not presented, there is no competition in this field of instrumentation. The article proposes the creation on the basis of the National Academy of Sciences of Ukraine a park of unitary, high-quality and affordable domestic XPS-spectrometers and the opening of a service center. The XPS method is necessary for most of the institutes of the National Academy of Sciences of Ukraine from the departments of chemistry, physics and astronomy, physical and technical problems of materials science, earth sciences and all specialized faculties of state universities. In general, for Ukraine, this is at least 50 spectrometers. The mechanism for the implementation of the project can be the formation of a state order for the development and manufacture of a batch of XPS spectrometers on the basis of imported and domestic components (50:50) and attracting business to the project. Creation of a network of Domestic XPS-spectrometers allows to obtain a sharp increase in the efficiency of scientific research in chemistry, physics, materials science and is one of the conditions for Ukraine’s transition to an innovative economy.

Scientific Achievements

Abstract This study examines the science and technology prize system of the Académie des Sciences through a first survey of the prizes granted over the period extending from the 1720s to the end of the 19th century. No reward policy was envisaged by the Royal Academy of Sciences in the Réglement (statute) promulgated by King Louis XIV in 1699. Prizes were proposed later, first by private donors and then by the state, and awarded in international contests setting out specific scientific or technical problems for savants, inventors and artists to solve. Using cash prizes, under the Ancien Régime the Academy effectively directed and funded research for specific purposes set by donors. By providing it with significant extra funding, the donor-sponsored prizes progressively gave the Academy relative autonomy from the political power of the state. In the 19th century, with the growing awareness of the importance of scientific research, the main question became whether to use the prizes to reward past achievements or to incentivize future research, and the scale and nature of the prizes changed.

Breast-fed infants in Bangladeshi villages were weighed at 1, 2, 6, 9 and 12 months. The concentrations of zinc and copper in the breast milk were measured and the daily intake of these elements calculated. Breast milk Zn concentration decreased over the year but was comparable with that found in developed countries. The calculated daily intake decreased from 17·7 to 8·0 μmol (10–30% of recommended dietary allowances (RDA); National Academy of Sciences, 1980). Breast milk Cu concentration also fell over the year and was lower than that reported from developed countries. Calculated daily Cu intake was 1·95–2·63 μmol (RDA 7·81–15·63 μmol). Deficiencies of trace elements may therefore be a problem in poorly nourished communities where breast feeding is continued for several years with only small amounts of additional food. Breast milk may not be adequate as the only source of infant nutrition after the first few months of life in Bangladesh.

Subject. The article is devoted to the problem of improving the ranking of the leading Russian technical universities by transforming them into multidisciplinary research universities with the limitation of technical faculties (programs) to 40–50% of the admission plan of entrants. Objectives. The study focuses on improving the position of Russian technical universities in international rankings, providing an opportunity for students to change their specialty or shape it, according to the requirements of the employer. Methods. I analyzed the structure of world-class technical universities in terms of differentiation of specialties and methods of improving the rankings. Results. The analysis shows that the leading positions in international rankings belong to multidisciplinary research universities that provide training and conduct integrated research at the intersection of different sciences. Conclusions. There is a need for gradual reforms of Russian research technical universities, in terms of compliance with global trends in multidisciplinarity, differentiation of funding, and research activities. Such reforms can be carried out in the form of mergers and creation of network structures on the basis of agreements on cooperation between technical universities and research institutes of the Russian Academy of Sciences.

Abstract. Since 2004, atmospheric carbon dioxide (CO2) is measured at the High Altitude Research Station Jungfraujoch by the division of Climate and Environmental Physics at the University of Bern (KUP) using a nondispersive infrared gas analyzer (NDIR) in combination with a paramagnetic O2 analyzer. In January 2010, CO2 measurements based on cavity ring down spectroscopy (CRDS) as part of the Swiss National Air Pollution Monitoring Network have been added by the Swiss Federal Laboratories for Materials Science and Technology (Empa). To ensure a smooth transition – a prerequisite when merging two datasets e.g. for trend determinations – the two measurement systems run in parallel for several years. Such a long-term intercomparison also allows identifying potential offsets between the two datasets and getting information about the compatibility of the two systems on different time scales. A good agreement of the seasonality as well as for the short-term variations was observed and to a lesser extent for trend calculations mainly due to the short common period. However, the comparison revealed some issues related to the stability of the calibration gases of the KUP system and their assigned CO2 mole fraction. It was possible to adapt an improved calibration strategy based on standard gas determinations, which lead to better agreement between the two data sets. By excluding periods with technical problems and bad calibration gas cylinders, the average hourly difference (CRDS − NDIR) of the two systems is −0.03 ppm ± 0.25 ppm. Although the difference of the two datasets is in line with the compatibility goal of ±0.1 ppm of the World Meteorological Organization (WMO), the standard deviation is still too high. A significant part of this uncertainty originates from the necessity to switch the KUP system frequently (every 12 min) for 6 min from ambient air to a working gas in order to correct short-term variations of the O2 measurement system. Allowing additionally for signal stabilization after switching the sample, an effective data coverage of only 1/6 for the KUP system is achieved while the Empa system has a nearly complete data coverage. Additionally, different internal volumes and flow rates between the two systems may affect observed differences.
