Seeking strength in diversity

An essentially limitless range of two-dimensional materials with diverse physical properties could be generated by marrying two concepts in advanced materials design.
High-entropy alloys are novel materials made by combining multiple chemical elements in roughly equal proportions. This mixed-up makeup can confer high stability, strength, corrosion resistance and tunable electronic properties.
High-entropy alloys were discovered at around the same time as graphene, a high-performance example of a van der Waals material, which consist of weakly bonded stacked arrays of two-dimensional atomic sheets.
Combining these two material types to form two-dimensional sheets of high-entropy alloys can be used to generate a wide new range of materials, a team that included two ShanghaiTech University researchers has shown.
These materials showed superconductivity, enhanced magnetic properties, and high corrosion resistance, and may find use as long-lived catalysts.
