Molecular Dynamics Simulation of Sensor-Enabled Geosynthetics

Hatami K., Yazdani H., Hawa T., Grady B.P., University of Oklahoma, US

Molecular Dynamics (MD) simulations are used to examine selected mechanical and electrical properties of Sensor-Enabled Geosynthetics (SEG) samples. Dreiding force field is adopted for the simulations which are carried out in the LAMMPS© environment. The [...]

Rapid Combustion Synthesis of Zinc Oxide Nanostructures

Merchan-Merchan W., Farmahini Farahani M., University of Oklahoma, US

In this contribution we show that Zn oxide nanostructures of various morphologies can be formed at high rates by using a counter-flow flame. A 1.0-mm in diameter Zn probes with a purity of ~99.99% is [...]

Using proton NMR to characterize functionalized single-walled carbon nanotubes

Nelson D.J., University of Oklahoma, US

Single-walled carbon nanotubes (SWCNTs) can be functionalized covalently at SWCNT ends, covalently at SWCNT sidewalls, or by complexation with SWCNT sidewalls. Each type of product has a wide range of applications, but sometimes the full [...]

A New QCA Architecture for the Future of Nano-Scale Computing

Hook IV L.R., Lee S-C, University of Oklahoma, US

By the time CMOS reaches its physical scaling limits in the next several years, computing will have very likely evolved to meet the demands imposed with increases in application complexity and the processing of enormous [...]

An Architecture for Designing Noise-Tolerant QCA Nanocircuits

Lee S-C, Hook IV L.R., University of Oklahoma, US

Due to many random factors from thermal fluctuations to wave interference, computation perfection in nanoICs is hard to achieve. Defects and faults arise from noise susceptibility of nanoICs which leads to unreliable results. A probabilistic [...]

Evolutionary selection of bone mineral hydroxyapatite binding peptide using landscape phage library

Modali S., Abbineni G., Jayanna P., Petrenko V., Mao C., University of Oklahoma, US

Hydroxyapatite [(Ca5(PO4)3OH)2] is a biomineral which is associated with bone proteins to form mineralized extracellular matrix in a mature bone. Using two landscape phage libraries, in which random octa-peptides and nona-peptides are displayed on all [...]

Utilization of SWNT-Filled Polystyrene Obtained by Miniemulsion Polymerization as a Modifier for High-Performance Epoxy Resins

Barraza H.J., Rueda O., Pompeo F., O'Rear E.A., Williams R.J.J., Resasco D.E., University of Oklahoma, US

One of the several reasons that engineering research aimed towards the purification, functionalization and incorporation of carbon nanotubes into polymeric matrices has been actively pursued for the last five years is that vastly important applications, [...]
