Polymer Nanocoatings by Initiated Chemical Vapor Deposition (iCVD)

Gleason K.K., Pryce Lewis H.G., Chan K., Lau K.K.S., Mao Y., Massachusetts Institute of Technology, US

Initiated chemical vapor deposition (iCVD) is a novel process capable of producing a range of polymeric and multifunctional nanocoatings. Coatings can be made extremely thin (down to 10nm) on objects with dimensions in the nanometer [...]

Multiscale Modeling of Self-Organized Mono-layer Surface Atomic Clusters

Hu Q., Ghoniem N.M., Walgraef D., University of California, Los Angeles, US

We present here a novel multiscale modeling approach to investigate the conditions for atomic cluster self-organization on atomically flat substrates during epitaxy deposition processes. A phase field model is developed for the free energy of [...]

Simultaneous Determination of Heavy Metals Using Array Based Optical Chemical Sensor

Choi Y., Ryoo D., Park S.H., Park S.Y., Park S.H., Park S.Y., Jeonju University, KR

A sol-gel optical chemical sensor encapsulated with complexing agents for simultaneous detection of selected heavy metals such as chromium, lead, mercury, and iron in aqueous media was fabricated. The sensor was prepared by acid catalyzed [...]

Micromachined Nanocrystalline Silver Doped Tin Oxide Hydrogen Sulfide Sensor

Gong J., Chen Q., Lian M-R, Liu N-C, University of Central Florida, US

We report here an ultra high sensitive micromachined hydrogen sulfide gas sensor with nanocrystalline thin (100nm) silver doped SnO2 film. A polymeric sol-gel process has been successfully developed in fabricating the thin SnO2 nanofilm as [...]

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 [...]
