Carbon nanomaterials have been extensively used in many applications owing to their unique thermal, electrical and mechanical properties. One of the prime challenges is the production of these nanomaterials on a large scale. This review paper summarizes the synthesis of various carbon nanomaterials via the chemical vapor deposition (CVD) method. These carbon nanomaterials include fullerenes, carbon nanotubes (CNTs), carbon nanofibers (CNFs), graphene, carbide-derived carbon (CDC), carbon nano-onion (CNO) and MXenes. Furthermore, current challenges in the synthesis and application of these nanomaterials are highlighted with suggested areas for future research.

“…Carbon nanotubes (CNTs) have attracted considerable interest as one of the most promising building components of nanoelectromechanical systems (NEMSs). − The nano-objects inside the CNTs can be driven using different methods, such as an electric field, − pressure gradient, , and thermophoresis. − The one-dimensional characteristics of the CNTs restrict the motion of objects that can only move along the CNT axis or rotate coaxially.…”

Carbon nanotubes based on mechanical deformation for controlling mass transport have various promising potential applications in nanofluidic devices. Thermophoresis of water nanodroplets through carbon nanotubes with deformation imposed by nanoindentation is explored using molecular dynamics simulations. We find that deforming the carbon nanotubes can effectively control the thermophoretic motion of the confined droplet. When the carbon nanotubes are deformed to a certain level, the migration of the droplet is significantly limited. Under strong deformation, the exchange of water molecules between separated droplets is blocked by a narrow passage. Moreover, we identify some interesting phenomena and important physical mechanisms, and explain them via the relationship between the molecular interactions between the interfacial water and the thermophoretic effect. The thermophoretic dynamics of a small droplet confined in the carbon nanotubes with a larger radius reveals that the interfacial interactions between the droplets and the carbon nanotubes form an energy barrier to prevent migration of the droplets.

“…For the cantilever designs, a lower F 0 usually means that a higher voltage is often required for the switch to pull down. To decrease the pull-in voltage, NEMS process [23,24,28,29] or liquid dielectric [30,31] is necessary. As logic devices, the NEMS are perfect [32][33][34], but the NEMS devices are hard to be used as power devices to convert tens or even hundreds of milliamperes current [35][36][37].…”

Electrostatic in-plane microelectromechanical systems (MEMS) relays/switches are widely applied for their low power consumption and simple process. However, compared to the out-ofplane designs, in-plane designs usually suffer from high pull-in voltage, since the feature size of the bulk-silicon process limits the gap between the driving electrodes. Area cost and speed usually have to be sacrificed to enhance the driving force and decrease the pull-in voltage.Balancing the pull-in voltage, speed and area cost is difficult for MEMS relays/switches but is essential in many practical applications. Comb structure is promising to relieve this contradiction. In this paper, we integrated the comb structure with the cantilever structure. As a result, the pull-in voltage decreased with the decreasing of the mass and area cost. A novel electrostatic lateral MEMS switch was introduced. The experiments have shown that 12 V pull-in voltage, 120 µs switching time with a 28 V driving voltage at atmospheric pressure, and small area were fabricated using a conventional bulk-silicon process.
