The rapid development of science and technology including cloud computing, chips, 5G, and artificial intelligence technology, has stimulated the recovery of the metaverse. From the technical point of view, we (it seems) have touched the threshold of the metaverse, which is no longer as far away as before.

The metaverse includes such six technologies as blockchain technology, interactivity technology (VR/AR/MR/XR/ER), game technology (game engine, game code, multimedia resources), AI technology, network communication technology, and Internet of Things. To support the operation of the huge metaverse, it also needs extremely powerful algorithms. The metaverse is a digital universe and a parallel world, which involves the application and development of Metaverse in various fields, including but not limited to: education, art, philosophy, industry, medicine, agriculture, forest.

Metaverse (Met) is an open-access academic journal that studies relevant issues on metaverse. Met also welcomes different types of articles including research article, case report, review, perspective, and method concerned with metaverse studies such as the concept definition and its development.

Micromaterials and Interfaces (MI) is an open access journal, which is accessible for those in the field of electrochemical technology and material science. Key researches include but are not limited to: elematerials science, electron microscopy research, electronic structure of material interface. Original research are willing to be collected on the physics and chemistry of micro-materials, such as the structure, physical properties and applications.
