Fluidic Molecular Processing Devices

Lyshevski M.A., Lyshevski S.E., Lyshevski M.A., Lyshevski S.E., Microsystems and Nanotechnologies, US

We study fluidic molecular processing devices and modules to perform processing and related tasks. These developments are envisioned to be utilized in foreseen processing and memory systems. We consider various fluidic devices as modular primitives [...]

An FPGA Architecture Using Vertical Silicon Nanowire Transistors

Bindal A., Wickramaratne D., Hamedi-Hagh S., San Jose State University, US

This study presents an FPGA architecture using vertical silicon nanowire transistors. A complete picture from designing ultra low-power silicon nanowire transistors to their use in an FPGA architecture is given. Post-layout, worst-case rise delay changes [...]

Total flexibility in thin film design using polymer nanocomposites

Druffel T., Buazza O., Lattis M., Farmer S., Optical Dynamics, US

Optically clear, mechanically flexible nanocomposites are created by doping host polymers with nanoparticles having higher or lower refractive indices. The composite materials preserve the viscoelastic properties of the binding polymers and exhibit infinite tunability between [...]

Thermal Cycling of 300 nm Buried Damascene Copper Interconnect Lines by Joule Heating

Read D.T., Geiss R.H., National Institute of Standards and Technology, US

We report tests of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric to failure under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured [...]

Improvement of Stab Resistant Body Armor Using SiO2 Nanoparticles Dispersed into Silane Coupling Agent through Sonic Cavitation

Lambert V., Mahfuz H., Bordner P., Florida Atlantic University, US

Enhancing a flexible body armor using the Shear Thickening Fluid theory (STF) with use of SiO2 nanoparticles has shown good results regarding the stab resistance. A completely new approach based on investigations demonstrates that silated [...]

High Strength Metal-Carbon Nanotube Composites

Goyal A., Wiegand D.A., Owens F.J., Iqbal Z., New Jersey Institute of Technology, US

Carbon nanotubes have been extensively investigated for developing polymer matrix nanocomposites and a number of such nanocomposites are already being used in various applications [1, 2]. Metallic composites, particularly those of aluminum, containing carbon nanotubes [...]

Fabrication of Nano-engineered Composites Reinforced with Carbon Nanotubes (CNTs)

Wicks S.S., Yamamoto N., Guzman de Villoria R., Ishiguro K., Cebeci H., Wardle B.L., Massachusetts Institute of Technology, US

Composites, consisting of aligned advanced fibers embedded in epoxy, are common structural materials used in the aerospace industry for their superior strength to weight ratio and their versatility in tailoring specific mechanical properties, among other [...]

Halloysite Nanotubes in Polymers

Daly R.C., Fleischer C.A., Wagner A.L., Duffy M., NaturalNano, Inc., US

Halloysite Nanotubes (HNT TM) provide a new avenue for the preparation of nanocomposites. These unique tubes can be dispersed by normal extrusion processes in a variety of polymer melts to produce nanocomposites with unusual physical [...]

Separation Mechanisms for Nanoscale Spheres and Rods in Field-Flow Fractionation (FFF)

Phelan Jr. F.R., Bauer B.J., NIST, US

A Brownian dynamics simulation for modeling the separation of spheres and rodlike particles in field-flow fractionation (FFF) is developed. Modeling of particle elution for spheres from (10 to 1000) nm was examined. The simulation captures [...]

Multi-Functional Carbon Nanotube Based Filtration Material

Cummings A., Seldon Technologies, Inc., US

The very small diameters of carbon nanotubes (CNTs) present relatively low resistance to fluid flow. This, combined with their high surface area, means that highly-efficient, bio-contaminant removals are possible with a thin filtration media possessing [...]
