The development of modern technologies in various industries cannot be imagined without the development and use of new materials, including new highly entropic alloys (HEA) and coatings based on them, as more advanced in terms of performance compared to traditional materials and coatings. Methods for producing various highly entropic alloys are described in many literature. Almost all such technologies at the moment cannot be applicable in the mass production of parts due to the high cost and lack of appropriate infrastructure and production technologies. However, obtaining coatings formed on the basis of highly entropic alloys for various parts of mechanisms and machines is currently a highly promising direction in improving the operational properties of work surfaces. The goal of this work is to create highly entropic coatings obtained by magnetron sputtering of special multicomponent targets. The paper shows the possibility of synthesis of coatings of the predicted composition and properties. A coating based on a matrix target made of 12Kh18N10T steel with pressed multicomponent Cr-Ni-Zr-Ti-Cu pellets was synthesized. The elemental composition of the coating and its properties were determined, the microhardness was measured, and the functional properties were established.

Abstract Research in termoacoustics began with the observation of the heat transfer between gas and solids. Using this interaction the intense sound wave could be applied to create engines and heat pumps. The most important part of thermoacoustic devices is a regenerator, where press of conversion of sound energy into thermal or vice versa takes place. In a heat pump the acoustic wave produces the temperature difference at the two ends of the regenerator. The aim of the paper is to find the influence of the material used for the construction of a regenerator on the properties of a thermoacoustic heat pump. Modern technologies allow us to create new materials with physical properties necessary to increase the temperature gradient on the heat exchangers. The aim of this paper is to create a regenerator which strongly improves the efficiency of the heat pump.

Some issues in pharmaceutical therapies such as instability, poor membrane permeability, and bioavailability of drugs can be solved by the design of suitable delivery systems based on the combination of two pillar classes of ingredients: polymers and lipids. At the same time, modern technologies are required to overcome production limitations (low productivity, high energy consumption, expensive setup, long process times) to pass at the industrial level. In this paper, a summary of applications of polymeric and lipid materials combined as nanostructures (hybrid nanocarriers) is reported. Then, recent techniques adopted in the production of hybrid nanoparticles are discussed, highlighting limitations still present that hold back the industrial implementation.

The article examines the origin and development of Russian graphic landscape art, performed in the technique of engraving on linoleum. It covers the period from the early 20th century, the moment the first masters of this direction of graphic art appeared in Russia, until the late 1960s when linocut, the landscape, in particular, reached its prime and acquired its completely individual, unlike any other graphic technique, characteristic. The authors analyze the linocut landscapes of notable artists of the period described starting with the founder, N.Sheverdyaev, and the leading propagandist of linocut in Russia, I.Pavlov. The article describes the distinctive features of engraving and making prints by famous artists of the 20th century, graphic artists, and not only. This is M.Dobuzhinsky, B.Kustodiev, V.Falileev, K.Kostenko, N.Piskarev, later I.Sokolov, P.Staronosov, and many other not so famous artists. The Soviet period is represented by A.Kravchenko, M.Matorin, I.Sokolov, S.Yudovin, and, of course, A.Zyryanov, one of the well-known printers of the 1960s. The linocut technique is well established in almost all types of landscape. These were industrial, agitational works, glorifying the work of Soviet people, colorful sheets, and lyrical, delicate, and poetic works. The architectural and rural landscape occupied an important place in the work of the letterpress masters: in the urban landscape, of course, the images of the two capitals prevailed, which is not surprising since most of the artists studied and worked in Moscow and Leningrad. The authors of the article drew attention to the creative work of N.Lapshin, F.Smirnov, N.Novoselskaya, A.Smirnov, and others. In the article, the authors try to show how versatile and complex the linocut technique, especially colored, is. The authors want to show that the art of engraving on linoleum helped to view the landscape genre in graphics differently and, possibly, influenced the development of the landscape in other types of prints and painting. The authors are trying to prove that linoleum engraving rightfully takes an equal position with woodcut and etching. The works of masters working in this technique are exhibited in all museums in the country.

Generative Organs

During long-term axenic culture of Chara continuous illumination (L=24) increases mitotic activity of almost all types of cells. In such conditions only initiation of oogonia is inhibited, leading into a strong predomination of male generative organs. Prolonged darkness (L:D=1:23) exerts a mitodepressing effect. Oogonia and antheridia are especially susceptible to the reduction of the light period. Modifications of the elongating growth in various photoperiods are different in the polyploid regions of the vegetative thallus and in haploid cells of the antheridial filaments. Segments of both axial internodes and lateral pleuridia increase their dimensions at L:D=1:23, whereas at L=24 their growth is significantly inhibited. Different reaction is noted in the cells of antheridial filaments: at L=24 they are about 10% longer than in the control (L:D=14:10). The duration of the antheridium aevelopment, from the stage of unicellular filaments to the moment of antheridium opening, is 1.5 days shorter at L=24 as compared with the control. This shortening includes proportionally both the period of divisions within antheridial filaments and the period of spermatozoid differentiation.

Classics of Polish Design. Post-War Polish Furniture Design the paper presents a review of Polish post-war design in the times of Polish People's Republic: in the 1950s and 1960s. It is the first paper in the series of "Classical Polish Design", presenting the results of research on Polish furniture and the icons of Polish design, carried out within the framework of dissertations in the Department of Wood Technology in the Warsaw University of Life Sciences (SGGW). The paper presents two main trends in Polish post-war design, together with their background. We analysed the development of industrial design and of mass production dedicated for mass users, as well as the education system for industrial designers. We present the concept of furniture for small living spaces and the impact of global trends, availability of new materials and technological solutions on Polish furniture design.
