Self Healing Hybrid Coating for Aggressive Environment

Vashisth C., Potrekar R., Roy Choudhury N., Dutta N.K., University of South Australia, AU

Self healing is a desirable property of a coating on metallic substrate to help arrest the development of micro-cracks and the propagation of corrosive species to the interfacial layer and eventually to the substrate. While [...]

Solution Growth of Nanostructured Ceramic Films

Cho J., State Univ of New York (SUNY) at Binghamton, US

Low-temperature processing that can lead to the development of highly-functional, strain-tolerant ceramic films will offer innovative solutions for the use of ceramic thin films and coatings. Current developments in organic and flexible electronics make the [...]

Design Parameters for “Robust” Superoleophobicity Surfaces

Law K-Y, Zhao H., Park K.C., Xerox Corporation, US

Earlier we reported the fabrication of a model superoleophobic surface comprising ~3-micron diameter pillar arrays on Silicon. Results showed that both surface fluorination and the re-entrant geometry are crucial in achieving the superoleophobicity with hexadecane [...]

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 [...]
