ABSTRACT
The research relevance is predefined by the fact that the European financial market has suffered a direct negative impact due to the russian aggression and violation of the territorial integrity of Ukraine. All these processes are accompanied by several previously formed and unfavourable trends for socio-economic and financial development, which have become even more severe due to the hostilities. In particular, COVID-19, environmental degradation, rising inflation, deglobalization, insufficient social development of individual countries, as well as fuel and food shortages. The research aims to conclude a comparative analysis of financial policy in European countries and individual countries of the Balkan Peninsula, as well as substantiation of the financial risk management features and the formation of a forecast model of economic stabilization. To achieve the set objectives, scientific methods were used, including analysis method, analogy method, and modelling method. The article analyses expert reports and the results of scientific research on the current state of the financial market and monetary policy in Europe as a result of the russian-Ukrainian war, in particular in the Balkans and Kosovo. The analogy of the directions of financial policy in the period before the russian invasion of the territory of Ukraine with the period of direct aggression of the russian federation is conducted. The fundamental reasons for changes in pricing policy, in particular pricing mechanisms, are characterized. The determining factors of financial risks, tools for assessing the consequences, as well as generalization of management methods for their reduction and elimination in the future are substantiated. The directions of European financial support aimed at the defence sector and socio-economic needs are considered. The practical value of the work is that the conceptual model of strategic development of the European financial market in the context of stabilization processes of international financial policy, as well as food and energy security was formed Copyright © The Author(s).
ABSTRACT
In recent years, due to the rise in energy prices and the impact of COVID-19, energy shortages have led to unsafe power supply environments. High emissions industries which account for more than 58% of the carbon emissions of Guangdong Province have played an important role in achieving the carbon peak goal, alleviating social energy shortage and promoting economic growth. Controlling high emissions industries will help to adjust the industrial structure and increase renewable energy investment. Therefore, it is necessary to comprehensively evaluate the policies of energy security and the investments of high emission industries. This paper builds the ICEEH-GD (comprehensive assessment model of climate, economy, environment and health of Guangdong Province) model, designs the Energy Security scenario (ES), the Restrict High Carbon Emission Sector scenario (RHS) and the Comprehensive Policy scenario (CP), and studies the impact of limiting high emissions industries and renewable energy policies on the transformation of investment structure, macro-economy and society. The results show that under the Energy Security scenario (ES), carbon emissions will peak in 2029, with a peak of 681 million tons. Under the condition of ensuring energy security, the installed capacity of coal-fired power generation will remain unchanged from 2025 to 2035. Under the Restrict High Carbon Emission Sector scenario (RHS), the GDP will increase by 8 billion yuan compared with the ES scenario by 2035. At the same time, it can promote the whole society to increase 10,500 employment opportunities, and more investment will flow to the low emissions industries. In the Comprehensive Policy scenario (CP), although the GDP loss will reach 33 billion yuan by 2035 compared with the Energy Security scenario (ES), the transportation and service industries will participate in carbon trading by optimizing the distribution of carbon restrictions in the whole society, which will reduce the carbon cost of the whole society by more than 48%, and promote the employment growth of 104,000 people through industrial structure optimization. Therefore, the power sector should increase investment in renewable energy to ensure energy security, limit the new production capacity of high emissions industries such as cement, steel and ceramics, and increase the green transition and efficiency improvement of existing high emissions industries. © 2022 by the authors.
ABSTRACT
Scintillators as the core materials of radiation detection play an important role in industrial nondestructive testing, medical imaging, high energy physics and safety inspection, etc.. Theexisting scintillator research faces both opportunities and challenges, especially in the context of COVID-19 pandemic period. It is of great practical significance to develop cost-effective scintillators and optimize their overall performance. The nano-glass composites (i.e., glass ceramics) have some advantages like high emission efficiency of scintillator crystals, simple preparation and low cost as an effective star scintillator. Based on the different luminescence centers, such scintillators can be broadly divided into rare-earth element ions doped or rare-earth-free luminescent nanocrystals embedded materials. This review represented recent development on the preparation of these materials, the relationship between the types of nanocrystals and their luminescence properties, and the potential applications of these materials in high-energy X-ray and gamma-ray detection. In addition, the existing problems in the research were discussed and the future development direction of nano-glass composite scintillators was also prospected. © 2022, Editorial Department of Journal of the Chinese Ceramic Society.
