Linear scaling techniques for first-principle calculations of large nanowire devices

Zhang D., Polizzi E., University of Massachusetts, FR

This paper aims to provide a sound basis to face the challenges in large scale atomistic simulations for applications ranging from material sciences and chemistry to nanoelectronics and bio-nanotechnology. In nanoelectronics, large scale ’ab-initio’ simulations [...]

New developments in the purification, filling and functionalisation of carbon nanotubes

Clarke R., Thomas Swan & Company Limited, UK

A substantial body of research has been focused on the preparation of high purity carbon nanotubes (CNT) in a large scale. Subsequently the purified CNTs can then be filled or functionalized depending on the envisaged [...]

Growth of Nanostructured Diamond, Diamond-Like Carbon, and Carbon Nanotubes in a Low Pressure Inductively Coupled Plasma

Okada K., National Institute for Materials Science, JP

A 13.56 MHz low pressure inductively coupled CH4/CO/H2 plasma has been applied to prepare nanocrystalline diamond particles of 200-700 nm diameter. The minimum diameter of the particles was found to be 5 nm. Two-dimensional platelet-like [...]

Diameter Selective Growth of Vertically Aligned Single Walled Carbon Nanotubes by Ethanol Flow Control

Hahm M.G., Noah M.A., Kwon Y., Jung Y.J., Northeastern University, US

The role of ethanol flow rate in CVD process for the diameter control of vertically aligned-SWNTs is presented. Three different flow rates of ethanol (50, 100, and 200 sccm) were supplied to grow VA-SWNTs while [...]

Systematic Approach on Modeling and Identification for Nanobattery Prototyping

Bhattacharya P., Ye Z., Walker E., Lacy F., Banerjee M., Southern University, US

Nanobattary microstructure consists of anode, cathode, electrolyte, separator for miniaturized power source. Miniaturization is a challenging area of research. Miniature power sources have a variety of applications on miniature power-controlled devices. Li-Ion is selected by [...]

Enlarge the distance of water molecules to incise microorganism cell-the development and application of nano-grade microorganism cell crushing machine

Hongwen Y., Suge G., Hebei University of Science and Technology, CN

We have developed a prototype nano-grade crushing machine that leads to improved yield. The machine utilizes ultrasound in connection with pressure as high as 3400 kg/cm2 to achieve final product with nanometer scale. We have [...]

High performance iPP based nanocomposite for food packaging application

Avella M., Errico M.E., Gentile G., INSTITUTE OF POLYMER CHEMISTRY AND TECHNOLOGY - CNR, IT

High performance iPP based nanocomposites filled with innovative calcium carbonate nanoparticles were prepared by melt mixing. Peculiarities of the nanoparticles were the high specific surface area, the elongated shape (aragonite), and the surface modifiers (polypropylene-maleic [...]

Preparation and Characterization of Various Nanofluids

Williams W.C., Bang I.C., Forrest E., Hu L.W., Buongiorno J., Massachusetts Institute of Technology, US

As part of an effort to evaluate water-based nanofluids for nuclear applications, preparation and characterization has been performed for nanofluids being considered for MIT’s nanofluid heat transfer experiments. Three methods of generating these nanofluids are [...]

Gas Sensor Arrays by Supersonic Cluster Beam Deposition

Barborini E., Leccardi M., Bertolini G., Rorato O., Franchi M., Bandiera D., Gatelli M., Wegner K., Raso A., Garibbo A., Ducati C., Piseri P., Milani P., Tethis S.r.l., IT

Supersonic cluster beam deposition was employed to produce nanostructured thin films of transition metal oxides to be used as gas sensors. The cluster beam was generated by a pulsed microplasma cluster source equipped with aerodynamic [...]
