The Future

Comparisons of the large nuclear accidents that occurred at the nuclear power plants in Chornobyl and Fukushima usually focus on the emission of radionuclides, the contamination area, doses to the public and liquidation workers, etc. However, little attention has been paid to various factors that affect decisions regarding the future development of these territories, such as the sociopolitical and economic situation in the countries during the accident and at the present time, the density and structure of the population, climate change, media coverage, and accessibility of information to the public. This article attempts to discuss the above factors, speculates about the paths for future development of both exclusion zones, and suggests the most promising areas for joint research in the future.

AbstractThe development of materials is one of the driving forces to accelerate modern scientific progress and technological innovation. Machine learning (ML) technology is rapidly developed in many fields and opening blueprints for the discovery and rational design of materials. In this review, we retrospected the latest applications of ML in assisting perovskites discovery. First, the development tendency of ML in perovskite materials publications in recent years was organized and analyzed. Second, the workflow of ML in perovskites discovery was introduced. Then the applications of ML in various properties of inorganic perovskites, hybrid organic–inorganic perovskites and double perovskites were briefly reviewed. In the end, we put forward suggestions on the future development prospects of ML in the field of perovskite materials.

Spray Coatings

Abstract High-temperature corrosion of critical components such as water walls and superheater tubes in biomass/waste-fired boilers is a major challenge. A dense and defect-free thermal spray coating has been shown to be promising to achieve a high electrical/thermal efficiency in power plants. The field of thermal spraying and quality of coatings have been progressively evolving; therefore, a critical assessment of our understanding of the efficacy of coatings in increasingly aggressive operating environments of the power plants can be highly educative. The effects of composition and microstructure on high-temperature corrosion behavior of the coatings were discussed in the first part of the review. The present paper that is the second part of the review covers the emerging research field of performance assessment of thermal spray coatings in harsh corrosion-prone environments and provides a comprehensive overview of the underlying high-temperature corrosion mechanisms that lead to the damage of exposed coatings. The application of contemporary analytical methods for better understanding of the behavior of corrosion-resistant coatings is also discussed. A discussion based on an exhaustive review of the literature provides an unbiased commentary on the advanced accomplishments and some outstanding issues in the field that warrant further research. An assessment of the current status of the field, the gaps in the scientific understanding, and the research needs for the expansion of thermal spray coatings for high-temperature corrosion applications is also provided.

Low Sulfur

Within the article an issues of implementing the new kinds of marine diesel fuels into ships’ operation was described taking into ac-count restrictions on the permissible sulphur content introduced by the International Maritime Organization. This is a new situation for ship owners and fuel producers, which forces the necessity to carry out laboratory research tests on especially adapted engine stands. How to elaborate the method enabling quality assessment of the self-ignition engine performance, considered in three categories: ener-gy, emission and reliability, represents the key issue of the organization of such research. In the field of energy research, it is necessary to know the thermal efficiency of the engine as the basic comparative parameter applied in diagnostic analyzes and syntheses of sequen-tially tested marine diesel fuels. This type of scientific research has been worked out for two years in the Department of Marine and Land Power Plants of the Gdańsk University of Technology, as a part of the statutory activities conducted in cooperation with the Regional Fund for Environmental Protection in Gdansk and the LOTOS Group oil company. This article presents the algorithm and results of thermal efficiency calculations of the Farymann Diesel D10 test engine in the con-ditions of feeding with various low-sulfur marine diesel fuels: distillation and residual fuels. This parameters stands for one of ten diag-nostic measures of the ranking of energy and emission quality of newly manufactured marine diesel fuels being built at the Department.

Available Information

According to recent estimates the mycota of Sri Lanka is highly diverse, yet it has been relatively little studied and remains poorly understood. Sri Lanka may contain up to 25,000 species of fungi, of which only a little more than 2000 are presently known, and this estimate does not take into account the large number of exotics introduced along with food, plantation, and ornamental plants. Mycological research in Sri Lanka has been limited to certain parts of the country, and the available information is widely dispersed, difficult to access, and plagued by synonymy. Commercially cultivable mushrooms were first introduced to Sri Lanka in 1985, and today both endemic and non-native species are cultivated. This paper addresses the current status of Sri Lankan mushroom research, and suggests measures which are needed to support the future development of Sri Lankan mycology.
