Ultrasonic Spraying of Carbon Nanotubes using NMP

Willey A., Davis R., Vanfleet R., Brigham Young University, US

We will present a new method for spraying thin films of carbon nanotubes, in which they are suspended in an organic solvent and then sprayed ultrasonically onto a heated substrate. These thin films have applications [...]

Shock Testing of Free Standing Silicon-Nitride and Beryllium Membranes

Brough D., Barrett L., Vanfleet R., Davis R., Liddiard S., Cornaby S., Coffin M., Brigham Young University, US

As micro and nanotechnology continue to advice into products, durability, reliability and robustness become important factors. One application where micro technology needs such qualities is X-ray windows. X-ray windows consist of free standing thin film [...]

Fabrication and Characterization of of Nanoscale Tellurium Fuses for Long Term Solid State Data Storage

Pearson A.C., Singh B., Linford M.R., Lunt B.M., Davis R.C., Brigham Young University, US

We have fabricated nanoscale tellurium fuses using electron beam lithography for long term data storage applications. The tellurium fuses contain a narrow resistive region(250 nm to 10 micron). Application of a sufficiently high voltage accross [...]

Low-Z, Chemically Resistant, Microfabricated Carbon Composite Transmission Electron Microscope Grids

Zufelt K., Vanfleet R., Davis RC., Brigham Young University, US

An issue that often impacts x-ray and electron analysis of transmission electron microscopy (TEM) samples is the presence of high-Z atoms in the sample substrate. In many cases, it is also desirable that the chosen [...]

A Novel Method for the Production of a Vast Array of Metal, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

Woodfield B.F., Liu S., Boerio-Goates J., Astle L., Brigham Young University, US

In this paper we discuss the materials that can now be produced using a novel method for producing large quantities of high-purity metal, metal oxide, and mixed-metal oxide particles. These nanoparticles are uniform in size [...]

A Revolutionary New Method for the Synthesis of a Wide Array of Metal Oxide and Mixed Metal Oxide Nanoparticles with Sizes as Small as 1 nm

Woodfield B.F., Liu Q., Liu S., Liu Q., Liu S., Astle L., Boerio-Goates J., Brigham Young University, US

We have developed a revolutionary new method for the production of large quantities of high-purity metal, metal oxide, and mixed-metal oxide nanoparticles. Particles are uniform in size with dimensions that can range from 1 nm [...]

In-Plane Transduction of Nanomechanical Microcantilever Motion To Enable Sensor Arrays

Nordin G.P., Kim S., Noh J., Qian Y., Brigham Young University, US

We have recently introduced a new microcantilever transduction mechanism that is designed to scale to large arrays on a single chip while maintaining a very compact form factor and high sensitivity. It is based on [...]

Simulation Studies of Channels in Biological Membranes

Henderson D., Busath D.D., Rowley R.L., Crozier P.S., Boda D., Brigham Young University, US

The results of our recent studies of the selectivity of a calcium channel by means of a Monte Carlo simulation and of the conductance of ions in a model channel by means of a molecular [...]

Modeling the Effects of Joint Clearances in Planar Micromechanisms

Wittwer J.W., Howell L.L., Chase K.W., Brigham Young University, US

Surface micromachining of micro-electro-mechanical systems (MEMS) has inherent limitations that can lead to mechanisms having an undesirable amount of clearance in revolute and prismatic joints. In micro devices, where actua-tion of the mechanisms is often [...]
