Abstract Heavy metal contamination of water resources is a critical issue which adversely affects humans. Ferrate(VI) (FeVIO42−, Fe(VI)), as a new type of green multifunctional water treatment agent, has shown promising potential for environmental decontamination. A complete understanding of the interactions between ferrate(VI) and toxic metals can be conducive to the further development of ferrate(VI) technology for application to wastewater treatment. This review first introduces the purification of ferrate(VI) technology for toxic metals including free heavy metals and metal complexes briefly. The effective parameters are then analyzed and discussed in detail. Subsequently, the reactivity and mechanisms of ferrate(VI) with toxic metals are emphatically described. Finally, possible research challenges and directions for ferrate(VI) technology applied to wastewater treatment in the future are summarized.

An electroactive polymer-ceramic hybrid actuation system (HYBAS) was recently developed. The HYBAS demonstrates significantly-enhanced electromechanical performance by utilizing advantages of cooperative contributions of the electromechanical responses of an electrostrictive copolymer and an electroactive single crystal. The hybrid actuation system provides not only a new type of device but also a concept to utilize different electroactive materials in a cooperative and efficient method for optimized electromechanical performance. In order to develop an effective procedure to optimize the performance of a hybrid actuation system (HYBAS), a theoretical model has been developed, based on the elastic and electromechanical properties of the materials utilized in the system and on the configuration of the device. The model also evaluates performance optimization as a function of geometric parameters, including the length of the HYBAS and the thickness ratios of the constituent components. The comparison between the model and the experimental results shows a good agreement and validates the model as an effective method for the further development of high performance actuating devices or systems for various applications.

ABSTRACTMokumé Gane layered metal is a 300-year old decorative metal laminate technique peculiar to the isolated culture of the Japanese Shogunate. Like many complex craft practices handed down through individual experience, the manufacture and development of Mokumé Gane has changed minimally over time. The application of contemporary metallurgical knowledge and solid state bonding techniques such as Hot Press Diffusion Bonding and Hot Roll Bonding provide for further development of Mokumé Gane: bonding success rates are improved, and manufacturing times are reduced. In addition, the range of possible metal combinations is substantially increased; 42 different combinations to date have been successfully bonded, including a new type of Mokumé Gane employing aluminium alloys. This research has allowed a very large increase in the variety of colours, patterns, and visual effects, available to contemporary metalsmiths and jewellers.

The purpose of the study is to prove the innovative approaches of F. Schubert in vocal works on the example of his later opuses – the vocal cycle „Winterreiseˮ, op. 90 („Winter Roadˮ) and the song collection „Der Schwanengesangˮ („Swan Songˮ). The methods of this proposed scientific article are based on the research approaches (historical, compare, analytical), which allow to us to follow the path of dramatization of the song in the late works of F. Schubert, as well as to determine the conformity of the vocal intonation to the poetic text. The material of scientific intelligence there are ten separate songs, namely, five songs from the vocal cycle „Winter Pathˮ and five songs on the lyrics by G. Heine from the collection „Swan Songˮ. In our opinion, they are not only indicative, but also similar in form, methods and content. The scientificnovelty of this research is to in the treatment to the issues of determining the correspondence of vocal intonation to a poetic text. Conclusions. Lyrics by Wilhelm Muller and Heinrich Heine are the peak of Schubertʼs vocal lyrics, the starting point for the further development of the song (romance) genre. Simplicity and the associated „sociability” of song intonation, on the one hand, naturally continue the traditions of the Austro-German song Lied. However, while the melody of Schubert reveals time fundamentally new qualities caused by the composerʼs innovative attitude to its formation. The reason for this is a great attention to the verbal text. The close interaction of poetic words and music, especially in the late works of the composer romantic, gives rise to a fundamentally new type of vocal intonation, a new level of voice and accompaniment and, as a final result, the emergence of a new quality of the chamber-vocal work – „poems with music”, thereby pushing on the further path of development of chamber vocal genres.

The event market has been developing in Ukraine for less than 15 years. It is a market with high competition, yet, according to experts, a low culture that requires research, study, and improvement. The article reveals the concepts: event industry, event technology, events, event management, event marketing, as well as describes the relationship between them. The event industry sector is studied based on the development of the creative economy in Ukraine. The conceptual model of event organization is built and the interrelation of its elements is investigated. The approaches to the practical application are described. The example of the State Enterprise “Arena Lviv” outlines the problems of development of the event industry in Ukraine in modern conditions, operating during the quarantine period associated with the prevention of the spread of acute respiratory disease COVID-19 in Ukraine. The article determines that in the quarantine period, the number of event measures decreased significantly, in particular, many planned activities were canceled or postponed. To hold events in compliance with all quarantine norms, the State Enterprise “Arena Lviv” proposed a new type and method of events - a project - a car cinema, where spectators stay in their cars and do not lose touch with art. Prospects and ways of further development of the event industry in Ukraine are described. The paper generalizes that for further development of the event industry in Ukraine, it is necessary to create conditions for the interpenetration of spheres that form the basis of the industry. It is determined that the government approaches to the development of the event industry should take into account the fact that the industry makes extensive use of human relations, so it is most vulnerable to emergencies and unusual social situations.

With the improvement of living standards, the requirement of food quality, nutrition, and freshness have been higher and higher. As the characteristics of highly effective, non-toxic, low cost, easy operation and significantly preservation effect, chitosan has been used widely as a new type of natural antistaling agent. Chitosan fresh-keeping mechanism and application in food preservatives are discussed in this study. From the three aspects of chitosan coating, composite coating, and chitosan modification, this work provides an overview of some researches about chitosan fresh food technology in abroad and domestic. And further development is discussed: the effect of the sole use of chitosan is not very good. Composite coating of chitosan will be more and more attractive with the merits about effectively preventing moisture loss, reducing weightlessness rate and so on. Storage stability about liquid chitosan can be solved by modified chitosan, which will also have a more attractive effect. This paper has theoretical significance to develop chitosan applications in food fresh-keeping technology.
