During the past few decades, materials design has shifted emphasis to pursue low cost, quality, light weight, environment friendliness, and performance. Aluminium matrix composites are important class of engineering materials used in aerospace, automotive, engineering, defence and other industries because of their lower density, higher specific strength, and better physical and mechanical prope...

Carbon nanotubes (CNTs) possess remarkable properties. They are very stiff and very strong, yet ductile. They can be conducting or semiconducting, depending on their chirality. Possible applications of CNTs include diverse areas such as conductive and high strength composites, energy storage and conversion devices, sensors, field emission displays and radiation sources, nanometer sized semicond...

This review summarises the research work carried out in the field of carbon nanotube (CNT) metal matrix composites (MMCs). Much research has been undertaken in utilising CNTs as reinforcement for composite material. However, CNT-reinforced MMCs have received the least attention. These composites are being projected for use in structural applications for their high specific strength as well as f...

studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...

We report on the nano-electron beam assisted fabrication of atomically sharp iron-based tips and on the creation of a nano-soldering iron for nano-interconnects using Fe-filled multiwalled carbon nanotubes (MWCNTs). High energy electron beam machining has been proven a powerful tool to modify desired nanostructures for technological applications (1-4) and to form molecular junctions and interco...

Carbon nanotubes (CNTs) incorporated porous 3-dimensional (3D) CuS microspheres have been successfully synthesized via a simple refluxing method assisted by PVP. The composites are composed of flower-shaped CuS secondary microspheres, which in turn are assembled with primary nanosheets of 15-30 nm in thickness and fully integrated with CNT. The composites possess a large specific surface area o...

The influence of dipping in hot salt solution on water absorption in nylon6 composites with dispersed aluminum powders was investigated. Dipping in hot salt solution (3mass%NaCl in distilled water) for 10 s at 373K increased the overweight of composite samples, whereas the addition of aluminum with dispersed powders (A1-addition) from zero to 40 vol%Al decreased the overweigh of the sample. Bas...

An anodic aluminum oxide (AAO) template was formed by a two-step anodization process. Carbon nanotubes (CNTs) were successfully synthesized along with AAO pores and the diameters of CNTs equaled those of AAO pores. The lengths of CNTs during a chemical vapor deposition synthesized process on the AAO template were effectively controlled. These AAO-CNTs exhibit excellent field emission with a low...

abstract background and aim: one of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. considering the diverse composition of available ...
