Special Issue Information

Dear Colleagues,

Over the last several decades, materials have been critical to the growth, prosperity, security, and quality of life of humans. Since the dawn of time, novel materials have been among the greatest achievements of every age. They have paved the way for new technologies in the fields of civil, chemical, construction, nuclear, aeronautical, agricultural, mechanical, biomedical, and electrical engineering that make use of functional materials such as biomaterials, packaging materials, and flexible electronics. Specifically, advanced materials in which the composition, structure, and surface are functionalized to confer specific, application-oriented properties.

This Special Issue collection will cover some of the latest developments in the synthesis, processing, and characterization of nanostructured functional materials for advanced applications. It will correlate the structure and properties for realistic applications. Ceramics, composites, electronic and optoelectronic materials, amorphous materials, crystalline materials, thin films, and nanostructured materials are examples of such materials.

Carbon nanomaterials are in high demand owing to their exceptional physical and chemical properties. This study employed a mixture of CH4, H2, and N2 to create carbon nanostructures on a single-crystal diamond using microwave plasma chemical vapor deposition (MPCVD) under high-power conditions. By controlling the substrate surface and nitrogen flow rate, carbon nanowires, carbon nanotubes, and carbon pompons could be selectively deposited. The results obtained from OES, SEM, TEM, and Raman spectroscopy revealed that the nitrogen flow rate and substrate surface conditions were crucial for the growth of carbon nanostructures. The changes in the plasma shape enhanced the etching effect, promoting the growth of carbon pompons. The CN and C2 groups play vital catalytic roles in the formation of carbon nanotubes and nanowires, guiding the precipitation and composite growth of carbon atoms at the interface between the Mo metal catalysts and diamond. This study demonstrated that heterostructures of diamond–carbon nanomaterials could be produced under high-power conditions, offering a new approach to integrating diamond and carbon nanomaterials.
