Dear Colleagues,

Carbon nanotubes (CNTs) are cylindrical nanostructures composed of carbon atoms arranged in a hexagonal lattice. They are one of the most versatile and promising nanomaterials with a wide range of applications due to their exceptional mechanical, electrical, thermal, and structural properties. Some key characteristics of CNTs include structure, strength, electrical conductivity, thermal conductivity, high surface area and flexibility and resilience. Carbon nanotubes can have a single-walled structure (SWCNT) or a multi-walled structure (MWCNT) depending on the number of concentric carbon layers. SWCNTs are single-layered, while MWCNTs have multiple layers nested within each other. CNTs are incredibly strong and have a tensile strength that is orders of magnitude higher than steel. They are also very lightweight. CNTs are excellent conductors of electricity due to their sp2 hybridized carbon atoms. This property makes them suitable for various electrical applications. CNTs exhibit high thermal conductivity, which makes them valuable in applications requiring efficient heat transfer, such as thermal management in electronics. The large surface area of CNTs is advantageous for applications like gas and liquid adsorption, catalysis, and as supports for nanoparticles. CNTs are highly flexible and can bend without breaking. They can recover their original shape after deformation, making them useful in applications requiring resilience.

Carbon nanotubes continue to be a subject of extensive research and innovation, offering numerous possibilities for advancing technology across multiple fields. Their unique properties make them valuable in a wide array of applications with the potential to revolutionize various industries. Carbon nanotubes (CNTs) have garnered significant attention in the field of energy conversion due to their exceptional electrical, thermal, and structural properties. These cylindrical nanostructures made of carbon atoms have a wide range of potential applications in energy conversion technologies

The main objective of this section is to play a leading role in shedding light on carbon nanotubes and their application in energy conversion. However, considering its interdisciplinary structure and potential impact to scientific and technological development in almost all fields, the goal of the section is to publish research articles/reviews supporting both experimental and theoretical models that will advance the research area.

We look forward to receiving your contributions.
