Formation of Biotinylated Alkylthiolate Self-Assembled Monolayers on Gold

Canaria C.A., Maloney J.R., Yu C-J, Smith J.O., Fraser S.E., Lansford R., California Institute of Technology, US

We demonstrate the successful formation of functional biotinylated monolayers on gold surfaces using aqueous solvents. Cyclic voltammetry (CV), alternating current voltammetry (ACV), and fluorescence microscopy have been used to characterize the films. Protein binding assays [...]

Ferroelectric Properties of FIB-prepared Single Crystal BaTiO3 Nanocapacitors

Schilling A., Saad MM., Baxter P., Adams TB., Bowman RM., Gregg JM., Morisson FD., Scott JF., Queen's University, Belfast & Nanotec NI, UK

Measurements on free standing single crystal barium strontium titanate capacitors made using focused ion beam micromachining with thicknesses down to 75 nm, show a dielectric response typical of large single crystals, rather than conventional thin [...]

Coating of Glass Surfaces with Nanoparticles of different Materials Synthesized in Microemulsions

López-Trosell A., Schomäcker R., TU Berlin, DE

In this paper a developed methodology is presented to coat glass substrates with nanoparticles of different materials. Particles of palladium, zirconium oxide, yttrium iron garned and perovskite Ca0.5Sr0.5MnO3 were synthesized in microemulsions. The microemulsions form [...]

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 [...]
