As it follows from Rietveld refnement of powder X-ray difraction data, both chalcogenides have orthorhombic symmetry and belong to Pmna space group. All experimentally observed Raman bands have been attributed to the theoretically calculated phonon modes, and the mode assignment has been performed. Prediction of mechanical properties (hardness and elastic moduli) of new boron-rich chalcogenides has been made using ab initio calculations, and both compounds were found to be members of a family of hard phases. ; Horizon 2020 Framework Programme 689279 Ministry of Science and Higher Education of the Russian Federation 2711.2020.2 National Natural Science Foundation of China 11604159 Center of Excellence has received funding from the European Union's Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-TeamingPhase2 under grant agreement No. 739508, project CAMART²

This book outlines the process of China's trade reforms over the past two decades and assesses the impact of these reforms on the economy. The author provides a detailed quantitative analysis to trace China's evolving commodity pattern of trade and changing comparative advantage structure over the entire reform period. Comparison is made between the trade patterns and comparative advantage to reveal the dynamic effects of the recent economic reform on resource allocation efficiency.

This commentary reviews An et al.'s (2021) article, 'Towards Confucian Geopolitics'. It first acknowledges the article's achievement in highlighting the importance of reading geopolitics by excavating the Chinese traditions and cultural perspectives. However, the commentary also points out that An et al.'s article has failed to understand the complex nature of the Confucian ideology by differentiating between real-world political struggle and cultural idealism. The lack of an evolving political geography has made their reading of Confucianism as either an official ideology or spatialisation unable to correspond with concrete historical realities. Specifically, it has resulted in over-simplification in benchmarking Chinese history and the dichotomous understanding of Hua-Yi division. The commentary further points out that the above problem is a general issue with the culturalist approach to world politics.
