Fabrication of Guided-mode Resonance Devices by Soft Lithography in Hybrimers

Lee K.J., Magnusson R., Jin J.H., Bae B.-S., University of Texas at Arlington, US

Diffractive optical elements and photonic crystals consist of fine spatial patterns designed to affect the spectrum, polarization, phase and other properties of light. Periodic layered structures are widely used in integrated optics, communication systems, spectroscopy, [...]

Cost Saving Strategies: Using a project planning process that can integrate capital and operational spending into a Nanofabrication Business Plan

Gregg A., Strnad M., Abbie Gregg, Inc., US

AGI will show how a project planning process that includes a business case analysis for nanofabrication buildings can help with many of the design, construction and operational decisions for the buildings. The typical building project [...]

Synthesis and characterization of nanoporous alumina films with controlled physical and chemical attributes

Monfared N.A., Atre S., Kishton R., Varadarajan S., Oregon State University, US

The performance of nano-porous surfaces and nano-porous membranes are highly dependent on the pore’s morphology, size and chemistry as well as their density and homogeneity. Therefore it is important to be able to control these [...]

Catalyst-Free, High-Speed Synthesis of ZnO Nanostructures

Pedersen J., Teh K.S., San Francisco State University, US

We demonstrate a rapid and catalyst-free method of synthesizing ZnO nanostructures on Si(100) using a low-power (65W) induction heating process. Our preliminary results show that we could grow ZnO nanostructures of specific geometries ranging from [...]

Self Aligned Multi-Layer Nano-Gap Electrodes for Fluidic and Magnetic Assembly of Carbon Nanotubes

Shim J.S., Yun Y.H., Schulz M.J., Ahn C.H., University of Cincinnati, US

A self aligned nano-scale gap was fabricated using conventional optical lithography, and applied for the assembly of a carbon nanotube (CNT). The new technique enables the formation of a sub-micron gap between self-aligned electrodes with [...]

Nanosilicate Filled Poly (vinyl chloride-co-vinyl acetate) and Epoxy Coatings for Steel Corrosion Protection

Allie L., Thorn J., Aglan H., Tuskegee University, US

The corrosion protection of nanosilicate filled poly (vinyl chloride - co - vinyl acetate) (VYHH) and epoxy resins has been studied. Nanosilicate was incorporated into VYHH at 0%, 0.5% and 1.5%wt loadings, and into epoxy [...]

Nanotechnology for Building Security

Elvin G., Green Technology Forum, US

Despite increased vigilance and annual federal anti-terrorism spending in excess of $55 billion, building security remains a major concern for most Americans. For those working in large governmental or institutional buildings, fears are particularly acute. [...]

Optimization of Phage-Based Magnetoelastic Biosensor Performance

Huang S., Yang H., Johnson M., Wan J., Chen I., Petrenko V.A., Chin B.A., Auburn University, US

A magnetoelastic (ME) platform coated with a bio-molecular recognition element (bacteriophage) for selective and specific recognition of Bacillus anthracis spores is described. ME materials have a mass-sensitive, characteristic, resonant frequency. In response to the binding [...]

Instantaneous Microbial Detection Demonstrated for Air & Water

Jiang J.P., McGill S., Morris S., BioVigilant Systems, Inc., US

Traditionally, growth based techniques have been the standard in environmental monitoring for evaluating the quality and quantity of microbial content. However, many studies have underscored the inadequacy of these techniques: (1) to provide environmental microbial [...]

Agent Reactive Modulated Optical Reflector for Hazardous Agent Detection

Kovalev A.E., Bray M.G., Mayer T.S., Werner D.H., Pennsylvania State University, US

We demonstrate a standoff passive sensor working in the near infrared range. The device uses a platform based on dielectric and metallo-dielectric layers. The sensor demonstrated a significant change in the reflection coefficient if exposed [...]
