Dear colleagues,

Carbon nanofibers (CNFs) are one-dimensional nanostructures with remarkable properties that make them invaluable in various practical applications. Their unique structure and exceptional properties have sparked interest in diverse fields, including materials science, electronics, and nanotechnology. CNFs are typically composed of graphitic carbon with a high aspect ratio. This tubular structure provides them with outstanding mechanical strength, excellent electrical conductivity, and a large surface area. These properties make CNFs ideal for a wide range of applications. CNFs, with their high electrical conductivity and strong mechanical properties, are used in the construction of field emission sources. These sources are essential components in X-ray tubes, producing intense, stable X-ray emissions for medical imaging, material analysis, and non-destructive testing. CNFs serve as exceptional electrode materials in supercapacitors. Their large surface area and electrical conductivity allow for high energy storage and rapid charge-discharge cycles. This is crucial in energy storage applications, including electric vehicles and renewable energy systems. CNFs have a high sensitivity to gases, making them excellent candidates for gas sensors. They can detect and measure trace amounts of gases in environmental monitoring, industrial safety, and healthcare, enhancing our ability to detect pollution, toxic gases, and disease markers. Understanding the growth and deposition processes of CNFs is critical for optimizing their properties in various applications. Different growth methods, such as chemical vapor deposition (CVD), arc discharge, and electrospinning, lead to CNFs with distinct structures and properties. The choice of deposition process impacts the final material's performance. Simulation is an essential tool for designing and optimizing CNFs' growth processes. Molecular dynamics simulations and computational modeling help predict the CNFs' structural properties and guide the experimental process. However, experimental verification is crucial to validate the simulations and understand the real-world behavior of CNFs. In conclusion, carbon nanofibers are versatile nanostructures with a wide range of practical applications, from X-ray emitters to supercapacitors and gas sensors. Understanding the deposition processes is crucial to tailor CNFs for specific applications, and simulations play a vital role in this. Combining simulation results with experimental verification ensures the reliability and efficiency of CNFs in real-world applications, contributing to advances in technology and materials science.
