Molecular Synergy in the Nano-networks

Znamirowski L., Silesian University of Technology, PL

Technology heterogeneity in the products or object fabrication system, where the external control system usually is based on silicon technology, the interface e.g. transducers or robots represents mixed technology, and the controlled process another, leads [...]

Atomistic Simulation of Cracktip Failure Pathways in Fe and Fe Alloys

Gordon P.A., Neeraj T., Li Y., Luton M.J., ExxonMobil Research & Engineering, US

This work employs transition pathway analysis to examine the activation barriers associated with failure of atomically sharp cracktips in Fe. The effect of structual and compositional heterogeneities are explored, as it is speculated that these [...]

Scanning Tunneling Microscopy Images of Au Adsorbed on GaAs(111)B surface

Yi H., Kratzer P., Hilner E., Mikkelsen A., KISTI, KR

We have studied the GaAs(111)B surface with Au deposited either homogeneously or as nanoparticles, and found the presence of Au in either form to give rise to a $(sqrt{3} !times! sqrt{3} )$ Au-induced surface reconstruction. [...]

QBITS Simulations for Develompment of Quantum Computer using the DSP 6711

Téllez V.H., Duchen G., Campero A., Iuga C., UAM, MX

Quantum computation is a new technology with the potential for providing exponential parallelism, but a quantum computation is a series of quantum logic gates. This work uses the DSP 6711 to simulate the different quantum [...]

Compact Modeling of Threshold Voltage in Nanoscale Strained-Si/SiGe MOSFETs

Nawal S., Venkataraman V., Kumar M.J., Indian Institute of Technology, IN

A simplae compact model for the threshold voltage of Strained Si/SiGe MOSFET is reported for the first time. This model accurately predicts the effects of Ge content and other device parameters on threshold voltage. The [...]

Modelling of Torsional Micromirrors with Springs made of Multiple Rotational Serpentine Elements

You J., Packirisamy M., Stiharu I., Concordia University, CA

In general, this paper presents the deduced analytical model and numerical simulation of electrostatically actuated torsional micromirrors with two symmetrical side springs of multiple rotational serpentine elements. Modelling of these kinds of micromirrors is carried [...]

Strong and Weak Inversion Mode of MOS in the Design of Direction Sensitivity Matrix

Husak M., Boura A., Jakovenko J., Czech Technical University in Prague, CZ

In the article there is presented a new arrangement of a temperature sensor system for air velocity and direction measurement. The system utilizes temperature dependence of the current through the channel of MOS structure. The [...]

Dielectrophoretic ratchets for linear and rotary nanomotors

Hughes M.P., Astumian R.D., University of Surrey, UK

Dielectrophoresis (DEP) is a phemomenon of induced particle motion in non-uniform electric fields. In this paper, we will describe how the phenomenon can be used to design electrokinetic ratchet devices to provide both linear and [...]

The Dynamic Performance of a Micro-machined Coriolis Flow Meter

Clark C., Wang S., Cheesewright R., Brunel University, UK

The dynamic performance of micro-machined Coriolis flow meters Summary The performance of a prototype MEMS mass-flow meter developed by ISSYS was investigated using the Brunel University Virtual Coriolis Meter facility. The flow meter comprises a vacuum sealed [...]

Lattice Boltzmann simulation of emulsification in microfluidics devices

van der Graaf S., van der Sman R.G.M., van der Graaf S., van der Sman R.G.M., Wageningen University, NL

Using microdevices we investigate the manufacturing of surfactant stabilised monodisperse food emulsions. Design of the process is a complicated matter, involving knowledge of wetting behaviour, droplet breakup in confined systems, surfactant dynamics coupled to droplet [...]
