in this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, ctab as cationic surfactant and butanol as a cosurfactant. surface modification have been carried out by using poly(ethyleneglycol) (peg). the structure,morphology, and magnetic properties of the products were characteriz...

Nanocontainers have great potentials in targeted drug delivery and nanospace-confined reactions. However, the previous synthetic approaches exhibited limited control over the morphology, size and materials of the nanocontainers, which are crucial in practical applications. Here, we present a synthetic approach to multi-segment linear-shaped nanopores with pre-designed morphologies inside anodic...

lithium disilicate nano-powders were synthesized via a mild condition hydrothermal reaction at 180 ºc for 48 and 72 h with a non stoichiometric1:2 li:si molar ratio in naoh aqueous solution using li2co3 and sio2.h2o as raw materials. the synthesized materials were characterized by powder x-ray diffraction (pxrd) technique and fourier transform infrared (ftir) spectroscopy. the xrd data showed t...

Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

Nano-plasticity of thin single-wall carbon nanotubes under uniaxial compression is investigated through generalized tight-binding molecular dynamics (GTBMD) and ab-initio electronic structure methods. A novel mechanism of nano-plasticity of carbon nanotubes under uniaxial compression is observed in which bonding geometry collapses from a graphitic (sp 2) to a localized diamond like (sp 3) recon...

Carbon nanomaterials (CNMs) are increasingly employed in nanomedicine as carriers for intracellular transport of drugs, imaging probes, and therapeutics agents, thanks to their unique optical and physicochemical properties. However, a better understanding about the effects of CNMs on a vertebrate model at the whole animal level is required. In this study, we compare the toxicity of oxidized car...

We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

Carbon nanotubes (CNTs) and carbon nanotube field effect transistors (CNFETs) have demonstrated extraordinary properties and are widely expected to be the building blocks of next generation VLSI circuits. This chapter presents (1) the first purely CNT and CNFET based nanoarchitecture, (2) an adaptive configuration methodology for nanoelectronic design based on the CNT nano-architecture, and (3)...

Owning to their unparalleled sensitivity resolution, nanomechanical resonators have excellent capabilities in design of nano-sensors for gas detection. The current challenge is to develop newdesigns of the resonators for differentiating distinct gas atoms with a recognizably high sensitivity. In this work, the characteristics of impulse wave propagation in carbon nanotube-based sensors are inve...
