A nanoscale machine shop for NWs

Cheng G.J., Li Ji, Purdue University, US

One-dimensional nanomaterials have attracted a great deal of research interest in the past few decades due to their unique mechanical, electrical and optical properties. Changing the shape of nanowires (NWs) is both challenging and crucial [...]

Directed Self Assembly: a Novel, High Speed Method of Nanocoating Ultra-thin Films and Monolayers of Particles

Powch G.A., Jain A.R., VersuFLEX Technologies LLC, US

A novel, practical fluidic method is presented for coating ultra-thin, ultra-uniform layers and realizing self-assembled monolayers of particles, into nanoscale in atmosphere and room temperature at rates scalable to web processes at >4 m/min. A [...]

Towards nanofabrication with UV femtosecond fiber laser

Huang H., PolarOnyx, Inc., US

In this paper, a UV fs fiber laser was used for direct writing nanofabrication on different materials. The laser used is a commercialized mode-locked fiber laser (PolarOnyx Uranus Series), generating typically Gaussian shape pulses (750 [...]

Milling Process Control with Dimensional Feedback on a Focused Ion Beam – Scanning Electron Microscope System (FIB-SEM)

Sanabia J.E., Raith USA, Inc., US

In nanofabrication and nanoanalysis, focused ion beam – scanning electron microscope (FIB-SEM) systems are increasingly used for demanding patterning tasks which rely on precise pattern placement and/or dimension control. Easily verifying and correcting for patterning [...]

Design and Fabrication of a Large Scale Electric Field Array Device for Directed Self-Assembly of Multilayer BioDerivatized Nanoparticle Materials

Heller M.J., Song Y., University of California San Diego, US

In earlier work, an electronic microarray device was used to carry out a bottom-up approach for the directed self-assembly of higher order 3D structures from biotin/streptavidin, DNA and enzyme derivatized nanoparticles. Structures with up to [...]

Impact of Channel Length and Gate Width of a N-MOSFET Device on the Threshold Voltage and its Fluctuations in Presence of Random Channel Dopants and Random Interface Trap: A 3D Ensemble Monte Carlo Stud

Ashraf N., Joshi S., Vasileska D., ASU, US

Previously we have reported threshold voltage fluctuations caused by presence of random distribution of dopant ions in the channel region of a 45 nm n-MOSFET and random single interface trap positioned from source to drain [...]

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 [...]

Functional Performance of Microfluidic On-Board Pumps and Valves with Various Actuation Protocols

Podczeviensky J., McDowell J., Levine L., ALine, Inc., US

Microfluidics are critical to the development of high sensitivity, multiplexed, and quantitative point-of-care diagnostic products that promise to improve the quality of healthcare while lowering costs. Fundamental to a shift from qualitative screening tests to [...]

Nanoparticle transport models in confined fluids

Mahadevan T.S., Kojic M., Milosevic M., Isailovic V., Filipovic N., Ferrari M., Ziemys A., The Methodist Hospital Research Institute, US

Mechanisms of nanoparticle (NP) and microparticle (MP) transport in confined spaces and role of material properties are not clearly understood, and transport models may not be complete. Here we present recently developed models of convective [...]

Modeling Particle-Fluid Coupling and its Impact on Magnetic Particle Transport in Microfluidic Systems

Khashan S.A., Furlani E.P., University at Buffalo (SUNY), US

Applications of magnetic particles have grown dramatically in recent years, especially for emerging microfluidic applications in the fields of microbiology, nanomedicine and biotechnology where they are commonly used to sort and separate biomaterials. Magnetic particles [...]
