Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations

Patankar N.A., Northwestern University, US

The interaction of sub-micron scale objects with fluids is an important problem encountered in miniaturized systems. Various physical phenomena should be modeled simultaneously for a fundamental investigation of these systems. Our objective is to develop [...]

Transient Analysis of Electroosmotic Flow in Nano-diameter Channels

Qiao R., Aluru N.R., University of Illinois at Urbana-Champaign, US

Transient analysis of electroosmotic flow in a nano-diameter channel is presented. The time for flow to reach steady state in a nano-diameter channel for various Debye lengths is investigated by solving the Navier-Stokes equations in [...]

Numerical and Analytical Studies of AC Electric Field in Dielectrophoretic Electrode Arrays

Feng J.J., Krishnamoorthy S., Chen Z.J., Makhijani V.B., CFD Research Corporation, US

Manipulation of micro-sized particles and biological cells using dielectrophoresis (DEP) is an emerging technique in MEMS and nano technology[3]. This paper presents an exact solution of dielectrophoretic motion of a polarized particle in the vicinity [...]

What to do with Statistical Mechanics when the Figure of Merit Cannot be Calculated: Library Design for High-Throughput Materials Development

Deem M.W., University of California, Los Angeles, US

By analogy with Monte Carlo algorithms, we discuss new strategies for design and redesign of libraries in high-throughput experimentation, or combinatorial chemistry. Several Monte Carlo methods are examined, including Metropolis, several types of biased schemes, [...]

The Inverse Band Structure Approach: Given the desired electronic property, find the atomic configuration

Zunger A., National Renewable Energy Laboratory, US

Modern crystal-growth techniques, such as molecular beam epitaxy or metal-organic chemical-vapour deposition, are capable of producing prescribed crystal structures, sometimes even in defiance of equilibrium, bulk thermodynamics. These techniques open up the possibility of exploring [...]

The Number of Human Genes and Proteins

Davison D., Bristol-Myers Squibb, Pharmaceutical Research Institute, US

The definitive prototype for nanotechnology is the cell. Its many machines and exquisitely controlled internal and external movements are a reference for all researchers working in the field. The complete instructions for every molecular machine [...]

Complex Fluid Dynamics in BioMEMS Devices

Liepmann D., University of California-Berkeley, US

MEMS technologies promises to revolutionize health care by providing precise control of biological fluids for both diagnoses and treatments. For example, microneedles can be used for sample collection for biological analysis, delivery of cell or [...]

Modeling and Simulation for MEMS Design, Industrial Requirements

Neul R., Robert Bosch GmbH, DE

The development process of today’s products is dominated by demands like ‘product performance’, ‘quality, ‘time to market’, ‘development cost’, ‘development risk’ etc., while the products’ complexity is increasing. Design methods for MEMS devices are discussed, [...]

The Vision and Action Plan of the National Nanotechnology Initiative

Roco M., National Science Foundation, US

The vision of novel phenomena, unity in nature, and promise of the most efficient manufacturing length scale has been essential in establishing the multidisciplinary National Nanotechnology Initiative (NNI). The research opportunities and projections of their [...]
