from the micro scale to the nano scale‚ though it is another matter in the periodic table that is used‚ Carbon. This leads us to the main issue of this project. Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more popular to the scientists. Initially‚ it was the spectacularly

Carbon Nanofibers Carbon nanofibers can simply be known as nanostructures with bonded carbon atoms that has a molecule composed entirely of carbon in shape of hollow sphere‚ ellipsoid or tube. The layers are usually wrapped up to form carbon nanotubes. Nanotubes are usually constructed with length-to-diameter ratio of up to 132‚000‚000:1. Basically‚ carbon nanofibers can be used very commonly in future as the technology for it is really taking its shape. It can be used for sensors‚ bone growth‚

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

This paper presents the design‚ fabrication and thermal imaging of three microheaters (Fig. 1) and the growth and characterization of single-walled carbon nanotubes (SWNTs) (Fig. 5) on these microstructures. SWNTs have many superior properties suitable for beyond-CMOS technology scaling and high-sensitivity chemical and biological sensors. For material synthesis‚ chemical vapor deposition (CVD) is a widely used method that produces high-quality SWNTs [1][2][3]. However‚ the high CVD growth temperature

Unit 4: Carbon Nanostructures Carbon Structures: • Carbon contains six electrons with electronic structure: (1s2)‚ (2s)‚ (2px)‚ (2py)‚ (2pz). Outer s orbital together with three p orbitals form the chemical bonds of carbon with other atoms. • Conventionally‚ solid carbon has two main structures called allotropic forms: diamond and graphite: - Diamond is tetrahedrally bonded through sp3 hybrid bonds that form a 3D network. - Graphite has a layered structure with each layer called graphene formed
