In the world of Integrated Circuits, Complementary Metal–Oxide– Semiconductor (CMOS) has lost its credentiality during scaling beyond 32nm. Scaling causes severe Short Channel Effects (SCE) which are difficult to suppress. As a result of such SCE many alternate devices have been studied. Some of the major contestants include Multi Gate Field Effect Transistor (MuGFET) like FinFET and Carbon Nan...

The acidic group (-CO2H) of MultiWall Carbon Nanotube (MWCNT) converted to acyl chloride group (-COCl) producing of MVCNT@COCl. Then the reaction of MVCNT@COCl and MoO2(acac)2 resulted in direct immobilization of the MoO2(acac)2 and the formation of MVCNT@CO(acac)MoO2(acac) catalyst. In addition, the MVCNT@COCl was esterified...

With CMOS technology being scaled to ever smaller dimensions to achieve higher performance and integration levels, power dissipation has become a major concern in modern VLSI designs. Sub-threshold circuits have gained a lot of importance due to ultra low-power consumption. The paper reviews the sub-threshold circuit design. Various body-biasing schemes and logic families for performance enhanc...

using c2h2, 112 and as gases at 550'c, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by dc magnetron sputtering. aystamless steel andfe/cteal, by thermal chemical vapor deposition (tcvd) the surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the cnt's growth is cri...

Sensor coverage will benefit from finding better ways to communicate among smaller sensors. Also, as development in nanotechnology progresses, the need for low-cost, robust, reliable communication among nano-machines will become apparent. Communication and signaling within newly engineered inorganic and biological nano-systems will allow for extremely dense and efficient distributed operation. ...

Nano-Sn/C composites are ideal anode materials for high energy and power density Li-ion batteries. However, because of the low melting point of Sn and the tendency of grain growth, especially during high temperature carbonization, it has been a significant challenge to create well-dispersed ultrasmall Sn nanoparticles within a carbon matrix. In this paper, we demonstrate an aerosol spray pyroly...

background: the presence of heavy metals in the environment especially in water supplies have caused many concerns because of their toxicity and non-degradability. hexavalent chromium (cr) is one of the most toxic metals which is used in many industries, so it is essential to remove it from industrial wastewater. in this study, we made a comparison between different adsorption isotherms in the ...

   Physical study of nano ribbon, tetragonal bundled and isolated nano tube SiC (7,0) are part of our project in knowing new nano material such a silicon carbide. These studies have been performed by density function theory. Effect of ribboning, tubulating and tetragonal bundling on the physical properties such as stability, structural constants, optical physics, chemical parameters and mag...

this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...
