Enhanced Mass Sensing for Nanomechanical Resonators

De Greve K., De Vlaminck I., De Greve K., De Vlaminck I., Naulaerts R., Sivasubramaniam V., Lagae L., Tilmans H.A.C., Borghs G., IMEC, BE

A new method for improving the mass detection limit of nanomechanical resonators in crystalline silicon, compatible with scaling, is demonstrated. Clamped-clamped silicon beam resonators are fabricated with a non-rectangular, ‘diabolo’ cross-section starting from SOI wafers. [...]

A Nanoelectronic Device Based on Endofullerene Peapod: Model Schematics and Molecular Dynamics Study

Kang J-W, Byun K.R., Lee H.J., Lee J-H., Lee H.J., Lee J-H., Hwang H-J., Chung-Ang University, KR

We investigated a nanoelectronic device based on multi endo-fullerenes shuttle memory element based on nanopeapods using classical molecular dynamics simulations. We suggested the model schematics of endo-fullerene shuttle memory device fabrication. The dynamics of the [...]

Preparation and Property of Novel CMC-tactile Sensors

Chen X., Yang S., Motojima S., Gifu University, JP

Carbon microcoils/nanocoils (CMC) have an interesting anisotropic morphology of 3D-herical/spiral structure such as a DNA or proteins. The CMC have double-helix or single-helix structure with a coil diameter of 0.05-10 _m and a coil pitch [...]

Calculating Deflection of Micro-Cantilever with Self-Assembled Monolayer Molecules Using Molecular Dynamics Simulations

Kan H-C, Wang Y-T, Tsai S-H, National Center for High-performance Computing, TW

Self-assembled Monolayers (SAM) by spontaneous adsorption of molecules on microscale substrates have attracted a huge interest due to their scientific importance and potential uses in technological applications and health care industry. Diverse selections of SAM [...]

Polyaniline Nanofibers and Composite Materials for Chemical Detection

Weiller B.H., Virji S., Baker C., Huang J., Li D., Kaner R.B., The Aerospace Corporation, US

Polyaniline is a conducting polymer with electrical properties that can change greatly upon exposure to various chemicals. Most notably, when polyaniline is exposed to strong acids and bases, the conductivity changes by greater than 8 [...]

Preparation of Zeolite Microspheres and their Application in Biology

Wong L.W., Yeung K.L., the Hong Kong University of Science and Technology, CN

The potential use of zeolite hollow microspheres in biological studies was illustrated in the study of formation of neuromuscular junction (NMJ). The hollow zeolite microspheres carry and locally deliver signalling molecules, thus mimicking the in [...]

Gold Removal and Recovery using Mesoporous Silica Adsorbents

Lam K.F., Yeung K.L., McKay G., Hong Kong University of Science and Technology, CN

This work investigates the selective removal of dissolved metal ions from aqueous solutions using MCM-41 adsorbents grafted with different chemical moieties. A systematic study was conducted to understand the adsorption mechanisms, in order to better [...]

RuO2 and Ru Nanoparticles for MISiC-FET Gas Sensors

Salomonsson A., Roy S., Aulin C., Ojamäe L., Käll P.-O., Strand M., Sanati M., Lloyd Spetz A., IFM, SE

Catalytically active nanoparticles used as gate material on SiC-FET gas sensors. The goal is to improve the selsectivity and senstitivty.The sensors are sensitive towards oxidising and reducing gases (H2, NH3, C3H6).

Nanostructured Gas Microsensor Platform

Routkevitch D., Polyakov O., Deininger D., Kostelecky C., Synkera Technologies, Inc., US

Nanostructured materials, with their small grain size, large number of grain boundaries, and high specific surface area, hold promise for significantly improving the performance of solid-state gas sensors. To fully realize this potential, precision nanoscale [...]
