Electric field induced self-assembled nanostructures in spray deposited nanocrystalline CdX and HgX (X= Se and Te) thin films

Dutta V., RangaRao A., Indian Institute of Technology Delhi, IN

In this paper we report on electric field induced self assembled nanostructures in the spray deposited nanocrystalline CdX and HgX thin films. Nanoparticles of II-VI semiconductors (CdX, HgX; X= Se, Te) have been synthesized using [...]

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 [...]

Fabrication of ZnO hybrid structures and light emitting diode applications

Park S.H., Seo S.-Y., Kwak C.-H., Lee Y.B., Kim S-H, Han S.-W., Chonbuk National University, KR

Vertically well aligned ZnO nanorod arrays with a diameter of 50 - 150 nm were fabricated on Al2O3 substrates with and without GaN interlayers, and consequently covered with a crystalline ZnO film in-situ by a [...]

Sensor application of ZnO nanowires on microheater

Park J., Kim G.-T., Maeng S., Udrea F., Milne W., ETRI, KR

We fabricated the ZnO nanowire network device using sol-gel synthesis method on the pre-patterned electrode and tested the electrical property for chemical sensing. The electrodes were prepared in various ways, for example, photolithographically defined interdigitated [...]

Synthesis of three-dimensional Mn3O4 nanostructures

Du C.S., Yun J.D., Browning N., Pan N., University of California at Davis, US

Owing to the large specific surface area and other superior properties over their bulk counterparts arising from quantum size effect, nanoscaled and nanostructured materials have attracted considerate research interest and many novel nanoscale materials have [...]

Wide Wavelength tuning of ZnSe Nanostructures by Temperature

Choy W.C.H., Leung Y.P., Jin L., Wang J., The University of Hong Kong, HK

As one of the most important II-VI compound semiconductors with a direct wide band gap, zinc selenide (ZnSe, bulk crystal Eg = 2.7 eV at 300K) [1] exhibits a great potential for various applications. In [...]

Controllable synthesis of patterned ZnO nanostructures based on the templation of plant cell walls

A novel approach based on vapor-phase transport technique using Au-coated plant cell walls with metallic ions as the catalyst has been developed to synthesize ZnO nanostructures. It is shown that plant cell walls can serve [...]

Light Induced Self-Inscription (LISI) in Organo-silica Network Glasses and Nanocomposite Polymers

Andrews M.P., Belanger N., Manseau M.-P., Duxin N., Maron E., Lofgreen J., van Veggel F.C.J.M., McGill University, CA

This talk focuses on two classes of nanocomposite media that exhibit Light Induced Self Inscription. We describe LISI in sol-gel derived photosensitive glasses containing nanodispersions of zirconia, titania and noble metal nanoparticles. Waveguiding at 488 [...]

Development of Mn2O3/SiO2 nanocomposite by sol-gel route

Prakash I., Muralidharan P., Nallamuthu N., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Nanocrystalline manganese oxides have been gaining importance in the fields of catalysis, electrochemistry, ion-exchange materials, magnetite, sensors, batteries, etc. An in - situ sol-gel process is investigated to synthesize uniform dispersion of the Mn2O3 nanocrystals [...]

Influences of the Surrounding Materials on CdTe Quantum Dots within Self-Assembled Thin Films

Gardner H.C., Bertoni C., Gallardo D.E., Dunn S., Cain M.G., National Physical Laboratory, UK

Semiconductor nanocrystals (NCs) have been successfully incorporated into nanostructured light emitting devices (NLEDs) and now promise applications in electronic, medical and telecommunication industries. To better understand and further develop NLEDs it is important to consider [...]
