2-D Materials: The Synthesis Of Solid-State Fuel From Metastable Diboride, Alma Kolakji

Chemistry

2-D materials are widely recognized for their anisotropic mechanical and electrical properties, surpassing their bulk counterparts. These superior characteristics of 2-D materials arise from their high surface-to-volume ratio and strong in-plane bonds. Current routes to exfoliate bulk material into 2-D nanosheets rely on weak interlayer Van der Waals forces and traditional top-down techniques. These methods are dominated by physical “force,” such as liquid-phase and mechanical exfoliation. The downside is that they apply only to weakly bonded VdW materials, limiting the variety of possible 2-D materials. To expand the variety, researchers have studied the synthesis of borophene (boron sheets). Borophene is …
