High entropy carbides (HECds) are multi-component carbides consisting of transition metal carbides.HECds are generally composed of five or more metal cations of the equal or near-equal substances,obtaining a single crystal structure.HECds have great potentials for future applications due to excellent mechanical,antioxidant and thermal properties.Due to their complex crystal structures and lattice distortion,computer simulations are widely used to efficiently associate the properties of HECds with the corresponding microstructures.In response to the development of HECds,this article provides an overview of the basic design,preparation process and properties of HECds. 展开更多

The CICG President Du Zhanyuan shares his insights about China-Europe talent cooperation.THE history of exchange between China and Europe is long and profound.Since the 16th century,European thinkers represented by Voltaire,Bertrand Russell,and Arnold Joseph Toynbee have taken Chinese philosophy as a valuable complement to the European ideological system.China has also absorbed the ideas of European giants such as Adam Smith,Georg Wilhelm Friedrich Hegel,and Karl Marx for its transformation and progress.In recent years,exchanges and interactions between the two sides in various fields have become increasingly close. 展开更多

In recent years,the international community has been facing a series of severe challenges to the global environment as the COVID-19 pandemic emerged as another alarm bell from nature to humanity.At the general debate of the 76th Session of the United Nations General Assembly held in September,Chinese President Xi Jinping proposed a Global Development Initiative aiming to steer global development toward a new stage of balanced,coordinated,and inclusive growth.He called on the international community to accelerate implementation of the UN 2030 Agenda for Sustainable Development and pursue more robust,greener,and more balanced global development.“We should stay committed to harmony between man and nature,”Xi stressed.“We need to improve global environmental governance,actively respond to climate change,and create a community of life for man and nature.” 展开更多
