“…Therefore, diamonds have been extensively studied for applications in electronic devices [15], thermal management, diffractive optical elements [16], and biomedicine [17]. In most applications, carbon nanomaterials are grown on substrates, such as silicon carbide, graphite, platinum, and nickel [18][19][20]. Existing evidence suggests that the heterostructure of graphene and diamond is beneficial for many applications.…”

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.

“…Hence, Environmental Science: Water Research & Technology Paper processing must be done carefully to ensure the formation of suitable formulations, as it affects the final product quality. 23 Graphene has a two-dimensional planar structure and is hydrophobic, which improves the mechanical, thermal, electrical, and functional properties of the membranes. 24 However, the inherent hydrophobicity of graphene and graphite makes them less attractive for the fabrication of hydrophilic membranes for oily wastewater treatment.…”

“…Moreover, Si 3 N 4 ceramics were predicted to have a theoretical thermal conductivity of 200–320 W·m −1 ·k −1 at room temperature in 1995 3 . Consequently, Si 3 N 4 ceramics have attracted considerable attention as a potential heat dissipation substrate material for high‐power electronic devices 4,5 . Therefore, the development of Si 3 N 4 ceramics with excellent mechanical properties and high thermal conductivity will undeniably promote the industrial applications of Si 3 N 4 ceramics as structural and functional materials.…”

Si 3 N 4 ceramics were prepared by gas pressure sintering at 1900 • C for 12 h under a nitrogen pressure of 1 MPa using Gd 2 O 3 and MgSiN 2 as sintering additives.The effects of the Gd 2 O 3 /MgSiN 2 ratio on the densification, microstructure, mechanical properties, and thermal conductivity of Si 3 N 4 ceramics were systematically investigated. It was found that a low Gd 2 O 3 /MgSiN 2 ratio facilitated the thermal diffusivity of Si 3 N 4 ceramics while a high Gd 2 O 3 /MgSiN 2 ratio benefited the densification and mechanical properties. When the Gd 2 O 3 /MgSiN 2 ratio was 1:1, Si 3 N 4 ceramics obtained an obvious exaggerated bimodal microstructure and the optimal properties. The thermal conductivity, flexural strength, and fracture toughness were 124 W⋅m −1 ⋅k −1 , 648 MPa, and 9.12 MPa⋅m 1/2 , respectively. Comparing with the results in the literature, it was shown that Gd 2 O 3 -MgSiN 2 was an effective additives system for obtaining Si 3 N 4 ceramics with high thermal conductivity and superior mechanical properties.
