In the era of the Internet of Things and 4th industrial revolution, soon every object that we interact with will be smart and multifunctional. To pack more and more functions in one object, we need to take advantage of every atomic layer to enhance performance and improve properties. Designing layered materials and structures, from the nano to the macro scale, would be the inevitable choice for the future of objects.
2D Layered Materials
2D transition metal carbides and nitrides (MXenes)
Few atom-thick 2D transition metal carbides and nitrides (MXenes) family is one of the rapidly expanding 2D materials beyond graphene. About 30 different MXene compositions have been synthesized, and structures and properties of about 60 MXenes have been theoretically predicted. The versatile chemistry of MXenes allows the tuning of properties for applications including energy storage, electromagnetic interference shielding, photonics, reinforcement for composites, water purification, gas- and biosensors, lubrication, and photo-, electro- and chemical catalysis.

Property tuning for different applications
MXene sheets have a 2D core of transition metal carbide and a surface of transition metal oxide. The availability of solid solutions, the control of surface terminations and a recent discovery of multi-transition metal layered MXenes offer the potential for the synthesis of many new structures.
