A unique carbon-based metal nanocomposite comprised of 80% carbonaceous matrix and a dispersed metal component of 20% aluminum material, represents a culmination of efforts in material science and manufacturing processes focused on the advancement of [...]

Yellow electroluminescence from sputtering synthesized aluminum nitride nanocomposite thin film containing aluminum nanocrystals

Yang M., Chen T.P., Liu Y., Wong J.I., Nanyang Technological University, SG

In this work, visible electroluminescence (EL) from aluminum nitride (AlN) thin films containing aluminum nanocrystals (nc-Al) prepared by a radio frequency sputtering technique is reported. The yellow EL shows a spectrum peaked at 565 nm. [...]

Molecular Dynamics of Self-Assembled Monolayer Formation in Soft Nanolithgoraphy

Heo D., Yang M., Jang J., Pusan National University, KR

Molecular dynamics simulation is performed to study the growth mechanism of self-assembled monolayer in the AFM tip-assisted soft nanolithography such as in dip-pen nanolithography [1]. We investigate how the droplet created around the tip spreads [...]

Effects of Silicon Nanowires on HepG2 Cell Adhesion and Spreading

Qi S., Yi C., Chen W., Fong C-C, Lee S-T, Yang M., City University of Hong Kong, CN

The unique capabilities of nanomaterials make them good candidates for catalysts, biosensors, and even drug carriers. However, interactions of nanomaterials with biological systems and the environment may lead to potential toxicity. While there have been [...]

Instability in flatband votlage of SiO2 embedded with silicon nanocrystals

Ng C.Y., Wong J.I., Yang M., Chen T.P., Nanyang Technological University, SG

In this work, the stability of the flatband voltage due to the Si-ions implantation into the SiO2 and subsequent annealing is being studied. There are lack of study on the impact of different annealing temperature [...]

Static dielectric constant of SiO2 embedded with silicon nanocrystals

Ng C.Y., Yang M., Wong J.I., Chen T.P., Nanyang Technological University, SG

The static dielectric constant of isolated silicon nanocrystal (nc-Si) embedded in a SiO2 thin film synthesized by Si+ implantation has been determined from capacitance measurement based on the Maxwell-Garnett effective medium approximation and the Stopping [...]

Electric Field Induced Self Assembly of Polymer Structures

Yang M., Ozkan C.S., Gao H., University of California Riverside, US

We have developed a method for fabricating polymer microstructures based on electric field induced self assembly and pattern formation. A dielectric fluid placed in between to conductive plates experiences a force in an applied electric [...]

Modeling and Optimal Design of High Sensitivity Piezoresistive Microcantilevers for Biosensing Applications

Yang M., Zhang X., Ozkan C.S., University of California Riverside, US

We discuss the mechanical design and optimization of piezoresistive microcantilevers for use in detecting changes in surface stress upon analyte-receptor binding. Conventional microcantilevers are used along with an optical detection system in many commercially available [...]
