Solution processed high Performance thin-film transistors using polymer/SWCNT composite ink

Zhang D., Zhang F., Lv N., Zhang D., Zhang F., Qiu S., Cui Z., Suzhou Institute of Nanotech, Chinese Academy of Sciences, CN

Semiconducting single-walled carbon nanotubes (s-SWCNTs) are increasingly being used for making inks for printed or solution processed thin-film transistors (TFTs) in printed and flexible electronics. However, the inherent insolubility of carbon nanotubes in most organic [...]

Novel Hierarchically Ordered Porous Vanado-Silicate Nanocomposites for the Application in Industrial Catalysis

Howard M., Whittle J., Zhang F., Zhao D., Sen T., University of Central Lancashire, UK

A novel hierarchically ordered porous vanado-silicate nanocompsoites were fabricated with isolated vanadium species with well dispersed state in the porous martrix for the oxidation of bulkier organic molecules i.e cyclooctene for the selective production of [...]

Patterning Technology for Nanomanufacturing

Smith H.I., Walsh M., Zhang F., Hourihan G., Ferrera J., Jaspan M., LumArray, US

We describe a new approach to patterning that circumvents the limitations of techniques that were developed for the semiconductor industry. The new approach, zone-plate-array lithograhy (ZPAL)will enable an expansion of applications of nanoscale science and [...]

Polarity sensitive colloidal gold nanoparticles

Amin F., Yushchenko D., Zhang F., Zulqurnain A., Parak W.J., Philipps Universität Marburg, DE

Polarity sensitive gold nanoparticles have been synthesized and their fluorescence properties have been measured. The effect of external factors such as alcohols, polyamines and detergents has been investigated.

Iridium Oxide Nanowire Monitors for Protein Detection

Venkatraman V.L., Reddy R.K., Zhang F., Hsu V., Ulrich B., Prasad S., Portland State University, US

The overarching research objective is the development of a “point-of-care” immunoassay device based on iridium oxide nanowires for disease state identification to predict human health outcomes. This device is based on electrical detection of proteins [...]

A Comparative Analysis of Iridium Oxide Nanowires in Electrical Detection of Biochemical Reactions

Venkatraman V.L., Reddy R.K., Zhang F., Hsu V., Ulrich B., Prasad S., Portland State University, US

Pt, Ir, Au and few other precious metals have highly conducive electrical and chemical properties; hence have been widely used in pH sensors and biomolecular sensing applications. The chief objective of this research is to [...]

Field Enhancement and Work Function Difference of IrO2 Nano-Emitter Arrays using EFM and SKPM Spectroscopy

Chiang D.C.-S., Lei P.Z.-F., Barrowcliff R., Zhang F., Washington State University and Sharp Corporation, US

We have measured two important physical properties related to field emission (surface potential and electric force gradient) of IrO2 nanorod emitter arrays using spectroscopy methods of electric force microscope (EFM) and scanning Kelvin probe microscope [...]

Developing PbSe/PbS Core-Shell Nanocrystals Quantum Dots (NQDs) for Light Emitting NQD/Silicon Heterojunctions

Xu J., Xu S., Cui D., Xu J., Xu S., Paradee G., Zhang F., Zhu T., Pennsylvania State University, US

In order to incorporate infrared colloidal nanocrystal quantum dots into silicon matrix to develop silicon-based light emitters, we report in this paper the epitaxial growth of PbS shells over PbSe NQDs with monolayer precision. The [...]

IrO2 Nano Structures by Metal Organic Chemical Vapor Deposition

Zhang F., Barrowcliff R., Stecker G., Wang D., Hsu S-T, Sharp Labs of America, Inc., US

This paper will discuss the deposition of IrO2 nano structures using (methycycpentadienyl) (1, 5-cyclooctadiene) iridium as the precursor and using Metal Organic Chemical Vapor Deposition (MOCVD) method with no template. Three different shapes of IrO2 [...]
