The surface analysis of nanomachined AISI D2 tool steel materials is measured using atomic force microscopy. The surface roughness and fractal dimensional analysis are the important factors in nano tribology and evaluating the quality of nanomachined surface. Carbon nanotube increases the heat carrying capacity, thermal conductivity of the lubricating oil and thus prevents any damage to the wor...

Recently, dense sensor instrumentation for structural health monitoring has motivated the need for novel passive wireless sensors that do not require a portable power source, such as batteries. Using a layer-by-layer self-assembly process, nano-structured multifunctional carbon nanotube-based thin film sensors of controlled morphology are fabricated. Through judicious selection of polyelectroly...

Carbon nanotubes (CNTs) are one of the most significant achievements of nano-technology because of its important applications in the design of electronic nano-devices. The study of their properties is therefore important. In this study, Density Functional Theory (DFT) was used to investigate the adsorption of gas molecules on the surface of carbon nanotubes. Theoretical studies have found that ...

Background and Objectives : Ethylbenzene (EB) is a dangerously organic compound which the presence of this pollutant in water solutions can be considered as an environmental and public health hazard. In this study, nano magnetic particles (Fe 3 O 4 ) were used as an adsorbent to remove ethylbenzene from aqueous solutions. Methods : The specification of the adsorbent was investigated by transmis...

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...

Carbon−based nano−conductive silicone rubber is a kind of composite conductive polymer material that has good electrical and thermal conductivities high magnetic flux. It application prospects for replacing most traditional materials, but its mechanical tensile strengths are poor, which limit applications. In this study, carbon fiber (CF), graphene (G) nanotubes (CNT) used as fillers to prepare...

Surface, interface and bulk properties of artificially structured, new magnetic materials play a fundamental role in modern science and technology. From thin films to patterned magnetic nano-structures, these magnetic materials and systems can be utilized in many electrical and electronic devices. Using highly surface sensitive techniques, electron capture spectroscopy (ECS), angleand energy-re...

Iron-dextran nanoparticles functionalized with T cell activating proteins have been used to study T cell receptor (TCR) signaling. However, nanoparticle triggering of membrane receptors is poorly understood and may be sensitive to physiologically regulated changes in TCR clustering that occur after T cell activation. Nano-aAPC bound 2-fold more TCR on activated T cells, which have clustered TCR...

Laser pyrolysis has been used to synthesize WO3 nanostructures. Spherical nano-particles were obtained when acetylene was used to carry the precursor droplet, whereas thin films were obtained at high flow-rates of oxygen carrier gas. In both environments WO3 nanowires appear only after thermal annealing of the as-deposited powders and films. Samples produced under oxygen carrier gas in the lase...
