Nanotubes are tiny cylindrical structures made of carbon atoms arranged in a hexagonal pattern. They can be single-walled or multi-walled, with diameters as small as one nanometer. Due to their unique structure, nanotubes exhibit remarkable strength and electrical conductivity, making them valuable in various applications, including electronics and materials science. These materials are often used in the development of advanced composites, batteries, and even medical devices. Researchers are exploring their potential in fields like nanotechnology and materials engineering, where their properties can enhance performance and efficiency in numerous products and technologies.
