To control the exhaust emissions from two stroke spark ignition engine, copper nano-particles coated on wire mesh at the junction of improved design as catalytic converter, AVL-422 gas analyzer was used for measurement and comparision for CO and unburnt hydrocarbon in the exhaust of the engine at various speeds and loads. In the present work, an improved design is proposed which is more suitabl...

Nickel based nano particles are metallic Ni and NiO. These materials find wide utility in various fields in view of their high surface potentials, surface area, semi conducting nature, reduction and complexing tendencies. The present review is mainly aimed at the investigations made in using these nano nickel particles as adsorbents in purifying water. The synthesis of nano particles of Ni/ NiO...

The crystal structure wasinvestigated by X-ray powder diffraction method and the values of the refined unit cell volumeand the structure properties were st...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...

using the nanotechnology and decreasing the dimension of reinforcement particles to nanometer, outstanding mechanical properties are achieved in aluminum matrix nanocomposites. fabrication of aluminum matrix nanocomposites by casting is of great importance because of its simplicity, low cost and ease of the control of matrix microstructure. in this study, the aging behavior of nanocomposite sam...

Nano-twinned copper exhibits an unusual combination of ultrahigh strength and high ductility, along with increased strain-rate sensitivity. We develop a mechanistic framework for predicting the rate sensitivity and elucidating the origin of ductility in terms of the interactions of dislocations with interfaces. Using atomistic reaction pathway calculations, we show that slip transfer reactions ...

background and objectives: zinc oxide (zno) nano-particles have been proven to have strong antibacterial activity against food borne pathogens. the practical applications of different concentrations (control, 0, 1, 2, 4, 6 and 8 mm) of zno suspensions containing 1% acetic acid were investigated against the pathogenic bacteria like staphylococcus aureus. materials and methods: the projects of la...
