Characterization of airborne particles released by the combustion of Nanocomposites

Motzkus C., Chivas-Joly C., Guillaume E., Ducourtieux S., Saragoza L., Lesenechal D., Macé T., Laboratoire National de Metrologie et d’Essais, FR

Day after day, new applications using nanoparticles appear in industry, increasing the probability to find these particles in workplaces as well as in ambient air. As epidemiological studies have shown an association between increased particulate [...]

Photo Catalytic Activity of Coated PET Fabrics with Synthesised Nano TiO2 & ZnO: A Comparative Study

Elahi A., Torkian L., Khajavi R., Azad University-Tehran South Branch, IR

The coated PET fabric with atomic ratios of Ti/(Ti+Zn) of 100%, 75%, 50%, 25%, and 0% was successfully prepared via sol–gel process from directly mixing TiO2/ZnO sol. The scanning electron microscopy (SEM) observation, energy dispersive [...]

Charge Confinement in Silicon Nanowires by Surface Functionalization

Shih Y.-C., Lee J-H., Lin C-T, Chen C-S, Wu K.-C., National Center for High-performance Computing, TW

Silicon nanowires (SiNWs) are expected to play an important role in nanotechnology because they possess remarkable physical property and compatibility with current Si-based fabrication. They have been successfully used in advance applications such as biosensors, [...]

Reinforcing Kevlar by Thin Outer Graphene Shell

Martirosyan K.S., Zyskin M., University of Texas at Brownsville, US

The development of advanced method to reinforce Kevlar fibers by using 2D graphene structures is reported. This method is based on the ultrasonic-assisted swelling of the polymeric fiber in a graphene suspension with the use [...]

Odd-Even Effect in Self Assembly and Phase Transition of Alkanethiols Monolayers (SAMs) on Au (111) Surfaces

Ramin L., Jabbarzadeh A., The University of Sydney, AU

Molecular dynamic simulations were conducted to predict the structural properties of n-alkanethiols CH3(CH2)n-1SH (n=4-22) self assembled monolayers (SAMs) on Au (111) surfaces. We studied the effects of chain length on the structural properties, including orientation [...]

Simultaneous determination of guanine and adenine on nano-poly(4-aminothiophenol) patterns modified ITO electrode

El-said W.A., Kim T-H., Choi J.W., Sogang University, KR

Here, poly(4-aminothiophenol) nano-patterns modified ITO electrode was fabricated to investigate the electrochemical behavior of A and G individual as well as simultaneous detection of mixture of A and G. The results demonstrated that nano-poly(4-aminothiophenol)/ITO can [...]

A novel strategy for fabrication of mesoporous crystalline tin dioxide films with large pores and fully crystalline walls

Fattakhova-Rohlfing D., Rathousky J., University of Munich (LMU), DE

We have developed a new facile procedure for manufacturing crystalline thin films of tin oxide with a uniform mesoporous architecture and full crystallinity of the walls. The procedure is based on the evaporation-induced self-assembly of [...]

Nanoporous Materials through Anodizing of Iron in F-containing Organic Electrolytes

Jagminas A., Mažeika K., Klimas V., State research institute Center of physical sciences and technology, LT

In this brief review, our recent progress in fabrication, characterization and application of thick nanoporous iron anodic films in ethylene glycol and a novel dimethyl sulfoxide (DMSO) electrolyte containing some fluorides will be presented and [...]

Enhancement of the magneto-optical activity via surface plasmon resonance on Au-Co nanocomposite thin films

Yang K., Clavero C., Skuza J., Lukaszew R.A., College of William and Mary, US

We find that the Au-Co nanocomposite thin films grown at 300 ºC, which exhibit segregate nano-cluster microstructure and smooth surface capable of SPP propagation, exhibit largest magneto-optical effects than the films grown at lower and [...]

White-Light Emission Characteristics of Nanoporous Silicon Membrane by Post-Treatment of Supercritical Fluid Technology

Lin J.C., Hsu M-K, Hou H-T, Wu J-Y, St. John’s University, TW

Nanoporous silicon (NPS) membrane with white-light emission property, including red, green and blue (RGB) colors by using the glucose post-treatment of supercritical fluid technology (SCF) is originally proposed in this paper. The electrochemical anodization with [...]
