| Abstract Scope |
Diamond is an exceptional material with fascinating applications due to its wide range of superior properties, including extreme hardness, low thermal expansion coefficient, high thermal conductivity, chemical inertness, and optical transparence. Its natural scarcity has driven quest for the ways to synthesize diamonds with chemical vapor deposition (CVD) which requires high-cost. Hexagon-shaped diamond two-dimensional (2D) nanoplates were obtained in the aqueous solution of acetonitrile at room temperature onto an anodized aluminum oxide (AAO) nanoporous template with a pore size of 150 nm, which was partly filled with cobalt (Co) nanowires being electrodeposited into the pores on the side of the silver-coated AAO surface. Acquired diffraction patterns from high-resolution TEM are indexed with Lonsdaleite diffraction data. The yield of 2D nanoplates was found to be dependent on crystallographic orientation of Co naowires. Investigation of mechanical properties by atomic force microscopy (AFM) resulted in the elastic modulus of 952 GPa. |
