This review paper provides researcherwith a comprehensive information about the Carbon Nano tubes and the catalyst parameters that influences theproduction and morphology of the of Carbon Nano tubes.Carbon nanotubes, referred to as CNTs, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. Since discovery of CNTs in 1991, many scienti...

A simple method has been developed for the preconcentration of benzene and phenolic compounds (BPC) by the adsorption of its carbon nanotubes (CNTs). The preconcentration of benzene and phenolic compounds (BPC) are ubiquitous pollutants, and many of them are carcinogenic or mutagenic. Carbon nanotubes (CNTs) are a kind of novel and interesting carbon material which can be used for separation an...

In this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. Mechanical properties of micro and nano- composites, including tensile strength, elongation, and Young’s modulus, before and after ageing, were determined and analyzed. For this purpose, micro- and nano-sized CaCO3 particles were used as fillers to prepare micro-composites (c...

The aluminum bronze matrix alumina composites using hot press and resin infiltration were investigated to study their porosities, hardness, bending strengths, and microstructures. The experiment results show that the hardness of the sintered composites with the decrease of porosity increases. The composites without and with resin infiltration have about HRF 42-61 of about 34-40% of porosity and...

In recent year’s aluminum and aluminum alloys are widely used in automotive industries. These are light weight (density of about 2.7g/cc),having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. High machinability and workability of aluminum alloys are prone to porosity due to gases dissolved during melting processes. However, in the engi...

Direct attachment of MoS2 to materials with carbonaceous architecture remains a major challenge because of non-intimate contact between the carbonaceous materials and active MoS2 material. In this study, we report a new unique synthetic method to produce a new type of hybrid nanostructure of MoS2-CNTs composites. We developed a novel strategy for the synthesis of cylindrical MoS2 directly grown...

Hybrid composite architectures employing traditional advanced composites and carbon nanotubes (CNTs) offer significant potential mechanical and multifunctional performance benefits. Dense patterns of well-aligned carbon nanotubes (CNTs) were grown on silicon wafers using a thermal chemical vapor deposition (CVD) process [1]. Wetting of CNTs and retention of mechanical properties of the fibers a...

Metal matrix composites reinforced by nano-particles are very promising materials, suitable for a large number of applications. These composites consist of a metal matrix filled with nano-particles featuring physical and mechanical properties very different from those of the matrix. The nano-particles can improve the base material in terms of wear resistance, damping properties and mechanical s...

Introduction As a new class of an ultra-high capacity anode material for Li-ion batteries, nano-Si/carbon composites have a considerable potential [1, 2]. In such composites, nano-Si can store lithium faster than bulk Si, and the carbon matrix serves nano-Si with an electrical path to compensate the poor electrical conductivity of Si. Though Si has an extremely high theoretical capacitance up t...
