A Comparison of Surface Acoustic Wave Modeling Methods

Wilson W.C., Atkinson G.M., NASA Langley Research Center, US

Surface Acoustic Wave (SAW) technology is low cost, rugged, lightweight, extremely low power and can be used to develop passive wireless sensors. For these reasons, NASA is investigating the use of SAW technology for Integrated [...]

Transition from exo to endo Cu absorption in SinCu clusters: A Genetic Algorithms Density Functional Theory (DFT) Study

Oña O.B., Ferraro M.B., Facelli J.C., University of Utah, US

The characterization and prediction of the structures of metal silicon clusters is important for nanotechnology research because these clusters can be used as building blocks for nano devices. Several authors have postulated that there is [...]

Multiscale modeling carbon nanotube growth on a supercapacitor electrode

Vasenkov A.V., CFD Research Corporation, US

Recently, the supercapacitors utilizing Carbon Nanotubes (CNTs) were reported. Currently, the fabrication of CNT-based supercapacitors involves manipulation of CNTs that is difficult and expensive owing to tiny size of CNTs. The direct deposition of well [...]

Design of Silicon-based Leaky-mode Resonant Nanopatterned Devices Using Inverse Numerical Methods

Shokooh-Saremi M., Magnusson R., Suleski T.J., Johnson E.G., University of Texas at Arlington, US

We present single-layer, silicon-based resonant leaky-mode elements implemented with periodic waveguide layers. This new device class has wide applicability in photonic devices and systems. Leaky waveguide modes can be exited when an incident light beam [...]

Molecular Simulation Studies for the Synthesis of Ni Nanowires in Zeolite Cancrinite

Huertas-Miranda J.A., Quiñones-Fontalvo L., Martínez-Iñesta M.M., University of Puerto Rico, US

Evaluation of the spatial distribution of Ni metal atoms inside CAN was done at two Si/ Al ratios and four Ni loadings. Using Sorption from Material Studio 4.0 (Accelrys, Inc.), Metropolis Monte Carlo simulations under [...]

An Online Tool for Simulating Electro-Thermo-Mechanical Flexures Using Distributed and Lumped Analyses

Li F., Clark J.V., Purdue University, US

We present an online software tool that enables both novices and experts to quickly and fairly accurately model and simulate an electro-thermo-mechanical microdevice. We model and simulate a MEMS thermal actuator by coupling finite element [...]

Oxylink™: Improved resistance for water borne coatings

Pilotek S., Burgard D., Herold M., Steingröver K., Buhler Inc., US

The overall market share of environmentally friendly water borne coatings is small compared to solvent borne alternatives. Today, they are used in a wide selection of market segments, such as wood and furniture, but also [...]

The Next Generation of Proteomic Nanochips for Biomarker Discovery

Hu Y., Tasciotti E., Bouamrani A., Liu X., Li L., Liu X., Ferrari M., The University of Texas at Austin, US

In this study, the nanoporous silica thin films (NSTF) were chosen for the reproducible fractionation and selective binding of the serum-based low molecular weight proteome (LMWP). It has been recognized that the collection of LMWP [...]

Wicking Study of Nanostructured Titania Surfaces for Flat Heat Pipes

Ding C., Bogorzi P., Sigurdson M., Soni G., Meinhart C., MacDonald N.C., university of california, santa barbara, US

We report a wicking material based on nanostructured TiO2 (NST) for the application of flat heat pipes. This wicking material is formed by oxidizing Ti pillar structures in H2O2 solution. The NST surfaces shows nano-scale [...]

Functional Polymer Micro- and Nanostructures by Nanoimprint

Cheng X., Park H., Cui D., Texas A&M University, College Station, US

We present here the patterning of polymer micro- and nanostructures by nanoimprint technique. Since its inception, nanoimprint has gained huge interest as a high-resolution and low-cost lithography technique for microelectronic fabrication. We demonstrate that nanoimprint [...]
