1. Introduction. A plethora of singlewall carbon nanotubes , multiwall carbon nanotubes MWCNTs , and their commercial applications have been extensively importance of using precursors to design the fabrication of determined carbon nanomaterials for specific applications has been intensely argued , , .In addition, transition metals such as Fe, Co, and Ni are known as
This study reports a highperforming nonprecious metal catalyst for the oxygen reduction reaction that is composed of highly dispersed Fe centered active sites on bamboolike carbon nanotubes. NH2MIL88B is used as the iron source and ZIF8 as the carbon source. The precursors are uniformly mixed by ball milling, which destroys their crystal structures. A bamboolike carbon nanotube network
The fabrication of micrometersized SiGC composites is mainly also relied on one simple, lowcost, and easily scaled up manufacturing method, such as ball millingmechanical milling, spray drying, chemical vapor deposition CVD, or wet processing, or on combinations of these methods, and the selection of raw carbon materials can also be
The effects of ball milling on cupstacked carbon nanotubes are summarized as follows. Two different cleavage modes are considered, based on TEM observations. It is expected that the bending mode plays the main role in cleaving carbon nanotubes from the viewpoint of the cupstacked morphology of these carbon nanotubes.

properties of the surrounding biomolecules. By ballmilling single walled carbon nanotubes SWCNTs we have introduced physical defects which alter their properties through physical deformations and additional electronic states in their energy structure. A higher defect density
BALL MILLING Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis ,partially filled with the material to be ground plus the grinding medium.
Ball milling is a grinding method that grinds nanotubes into extremely fine powders. During the ball milling process, the collision between the tiny rigid balls in a concealed container will generate localized high pressure. Usually, ceramic, flint pebbles and stainless steel are used.25 In order to further improve the quality of dispersion and
Conversely, chemical vapor deposition is a method to produce a desired solidstate material. In the case of CNTs, CVD is used to dissociate the organic portion of a molecule and leave the C atoms

Nano Ball Milling 1. BALL MILLING METHOD By Aravind N. B 2. Nano materials can be defined as those materials which have structured components with size less than 100nm at least in one dimension. Nanotechnology is an advanced technology, which deals with the synthesis of nanoparticles, processing of the nano materials and their applications.
2.Single wall carbon nanotube SWCNT additives have been shown to significantly improve mechanical and conductive properties in elastomers in extremely low concentrations work has incorporated SWCNT using various approaches in mixing and compounding 1. Mixing ultrasonication, calendering, ball milling, shear mixing, and extrusion 2.
Recently, carbon nanotubes CNTs are attracting much interest as fibrous materials for reinforcing aluminium matrix composites due to unique properties such as high strength, elastic modulus, flexibility and high aspect ratios. However, the quality of the dispersion is the major concern factor which determines the homogeneity of the enhanced mechanical and tribological properties of the
Carbon nanotubes reinforced pure Al CNTAl composites were produced by ballmilling and powder metallurgy. Microstructure and its evolution of the mixture powders and the fabricated composites were examined and the mechanical properties of the composites were tested.
The optimum conditions for ball milling to obtain the optimal structure of carbon nanotubes for hydrogen adsorption need further investigation.
