Precise Simulation of Freezing Transitions

Despite recent advances, precise simulation of freezing transitions remains a challenging task. In this work, a simulation method for fluid-solid transitions, based on a modification of the constrained cell model of Hoover and Ree, is [...]

A Nano-Scale Module with Full Spin-Wave Interconnectivity for Integrated Circuits

Eshaghian-Wilner M.M., Khitun A., Navab S., Wang K.L., UCLA, US

In this paper, we present a nanoscale computational architecture for integrated circuits where the nodes intercommunicate using Spin Waves. The key advantage of the proposed architecture is that the information transmission is accomplished without charge [...]

Using Surface Plasmon Propagation through Nanostructures for Chemical and Biological Sensing

Benahmed A., Ho C-M., UCLA, US

By taking advantage of the properties of the propagation of surface plasmon waves through nanostructures, we developed a new chemical and biological sensor. Compared to traditional Surface Plasmon Resonance (SPR) sensing, our sensor does not [...]

Development of a Self-Assembled Muscle-Powered Piezoelectric Microgenerator

Xi J., Dy E., Hung M-T, Montemagno C., UCLA, US

As technology advances into a new era of N/MEMS, powering these tiny devices becomes a significant issue. To address this issue, a self-assembled living/nonliving microgenerator has been developed through seamless integration of PVDF-TrFE and neonatal [...]

Modeling and Simulation for Epitaxial Growth with Strain

Caflisch R.E., Connell C., Luo E., Gyure M., Simms G., Vvedensky D., UCLA, US

We describe a new approach to simulation of epitaxial growth with strain. An island dynamics model with a level set numerical method is used for the growth, a lattice statics model is used for the [...]

Prediction of the Pressure Drop Through Micromachined Particle Filters

Yang J.M., Yang X., Yang J.M., Yang X., Ho C-M., Tai Y-C., UCLA, US

Micro-filters are fabricated using MEMS technology, and both measurements and numerical calculations are carried out in order to estimate the power requirement in a micron-size particle collection process using the micro-filter. In order to numerically [...]
