in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...

The carbon based coils with the nanometer scale have the 3 dimension helix geometry. We synthesized the carbon nano-coils by the use of chemical vapor deposition technique with iron and tin as the catalysts. The fabricated coils have the external diameter of ranging few hundred nm to few thousand nm. The Scanning Electro-Microscope (SEM) and Tunneling Electro-Microscope has shown detail images ...

The numerical scrutiny of unsteady incompressible magneto-hydrodynamics (MHD) for blood flow in carbon nano tubes (CNTs), past a sensor surface has been presented under the influences viscous dissipation, resistive heating, and thermal radiation. variables without having dimensions have deployed to alter reigning equations, which are non-linear, coupled partial differential equations (PDEs), in...

A possible way to increase thermal conductivity of working fluids, while keeping pressure drop at acceptable levels, is through nanofluids. Nanofluids are nano-sized particles dispersed in conventional fluids. great number materials have potential be used nanoparticles production and then nanofluids; one them Multi-Walled Carbon Nano Tubes (MWCNT). They around 3000 W/mK other as like CuO 76.5 W...

The aim of the study was to investigate the flexural and impact strength of 3 commercially available denture base resins after reinforcing them with single walled carbon nanotubes (SWCNT’S). Each acrylic resin was first solubilised in Tetrahydrofuran (THF) and then carbon nanotubes were added in different percentages respectively. A total of 50 specimens were made from each material (Eclipse, T...

Nanoelectronic devices: nanoparticles or fibers can be integrated into smart devices and has broad applications in variety of fields, such as computer chips, nano-sensor, electrical switching, emission amplification, and more efficient solar cells. Carbon-based nanomaterials are intentionally produced fullerenes, which involve carbon nanotubes and buckyballs (National Geographic 2014). For carb...

Nano-carbon materials are promising canidates for applications in high performance devices, including highly sensitive biosensors. We have developed a self-alignment process for nano-carbon field effect transistors (FETs), using a carbon nanowall (CNW)—a nano-carbon materials—to fabricate CNW-FETs. We measured the pH dependence of the device properties. The binding molecules are known to be key...
