High efficiency capture of multiple bacterial species by microfluidic dielectrophoresis filter

Simon S., Weber M., Fluid-Screen, Inc., US

Fluid-Screen, Inc. presents a bacterial concentration and filtration method based on dielectrophoresis (DEP). DEP has been known to induce particle motion since the 1960’s. However, yields and reproducibility have consistently been low in practice, reducing [...]

Artificial Nanostructure Materials for Optical Power Control Devices

Ofir Y., Donval A., Cheskis D., Fisher T., Oron M., KiloLambda, IL

The design of artificial nanostructured materials for the use in non-linear devices and integrated photonic systems is very challenging as it involves the need to incorporate the nanoparticles, nanomaterials and quantum physics equations. Near-field interactions [...]

microGreen Extended Performance Oil Filter

Assion N., Sahoo D., Flamenbaum M., SOMS Technologies LLC, US

By significantly improving the filtration efficiency of a vehicle engine oil filter the use of the engine oil can be greatly extended, reducing motor oil consumption and generation of hazardous waste. This was demonstrated by [...]

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, [...]

Drinking water treatment with Caspian region natural sorbents

Egorov M.A., Astrakhan State University, RU

The present work is focused on developing effective and efficient mass consumer household filters to treat drinking water with natural sorbents which is especially important for developing regions communities. The aim of the research was [...]

Porous filter with spatially graded response

Krause K.M., Hawkeye M., Brett M., University of Alberta, CA

Glancing Angle Deposition (GLAD) has become a common technique for producing thin porous films with various structural features. In the current work, we have further modified GLAD in order to create porous structures that have [...]

Add-Drop Filters utilizing Vertically Coupled Microcavities in Silicon

Koonath P., Indukuri T., Jalali B., University of California, Los Angeles, US

Micro-resonant optical cavities facilitate dense integration of optical devices on a chip. Through vertical integration of devices, precise control over the critical dimension of the structure can be achieved. Add-drop multiplexers based on vertically coupled [...]
