Abstract: Graphene, a two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice, has emerged as a revolutionary material due to its exceptional physical, chemical, and mechanical properties. Its unique structure endows it with remarkable electrical conductivity, high mechanical strength, excellent thermal conductivity, and a large surface area, making it a versatile material across various applications. In electronics, graphene shows potential as a replacement for silicon in transistors, enabling faster and more efficient devices. In energy storage, its high surface area and conductivity enhance the performance of batteries and supercapacitors. Furthermore, graphene’s chemical inertness and mechanical exibility make it an excellent candidate for sensors, composites, and coatings.
Keywords: High entropy alloys, Nanomaterials, Electron Microscopy.
Introduction:
The concept proposed by both Cantor in UK and Yeh in Taiwan, has led to a new class of material, popularly known as “high entropy alloys” and proven to be significantly influential in the design of new materials providing solutions to some of the problems humanity facing today [1, 2]. HEAs’ basic advantage over the conventional bi and tri-metallic alloys is the presence of multiple species providing outstanding physiochemical, surface, and electromagnetic properties, including extraordinary catalytic activity with reasonably good stability, which can rather be regulated by tuning the content of each species depending on the need. Initially, HEAs were investigated for the structural materials and inundated with studies to understand the mechanical properties with various alloy compositions[3,4]. Recent literature shows the potentials of HEAs as a functional material, which could be applied in different areas due to tunable composition as well as emerging new properties. Since, the field is broad and highly unexplored, they will constitute a paradigm shift in catalysis and energy applications by providing a useful handle to discover novel catalysts with improved activity, selectivity, stability via intelligent navigation of the vast compositional space and surface microstructure. HEAs are blessed with outstanding properties due to some salient effects associated with multi-principal component nature. Among them, the “cocktail” effect due to the mixing of different atomic species is related to the emergence
