Plasmonic nanodome array fabricated on plastic as a dual-mode surface plasmon resonance and surface-enhanced Raman scattering sensor

Choi C-J, Semancik S., National Institute of Standards and Technology, US

Label-free optical sensors have recently emerged as a highly sensitive approach for detecting a broad range of chemical and biological analytes that include illicit drug compounds, explosives, proteins, viruses, and bacteria.To best meet such diverse [...]

Luminescent Water Soluble Carbon Quantum Dots for Bio-imaging and Target Drug Delivery

Allam A., Allam A., Cromoz Inc, US

Biologists for years have been trying to visualize the movement and action of proteins and other molecules in and around cells and tissues. Transgenic way of attaching green fluorescence proteins started to help in such [...]

Development and Application of a Rod and Sphere-Shaped Viral Nanoparticle MRI Contrast Agent for Atherosclerosis Diagnosis

Bruckman M.A., Steinmetz N.F., Case Western Reserve University, US

The use of nanoparticles to deliver magnetic resonance (MR) contrast agents to enhance MR sensitivity has shown great potential in identifying and diagnosing diseases such as cancer and cardiovascular disease. A common challenge is the [...]

A Nanodiamond is Forever: Functionalizable fluorescent nanodiamonds that do not photobleach or blink for in vitro and in vivo imaging

Bumb A., Sarkar S., Brechbiel M., Neuman K., National Heart, Lung, & Blood Institute, US

Fluorescent nanodiamonds (FNDs) are a new category of nanoparticles with optical properties that make them superior imaging probes that could replace commonly used fluorescence agents (i.e. dyes and quantum dots). In particular, their near infrared [...]

Infrared Sensor Interference Isolation for Low-Cost Three-Dimensional Anemometers

Hirano J., Garmire D., University of Hawaii at Manoa, US

The further integration of wind power generation into our power grids from residential and industrial building installations increases the need to gather high spatial resolution wind data. This results in a need for low-cost three-dimensional [...]

Self-Sustaining Meteorological Wireless Sensor Networks

Carland J., Oberbeck A., Umeda M., Cumming J., Wilkey T., Fripp M., Kuh A., Garmire D., University of Hawaii at Manoa, US

Existing electrical grid infrastructure designs cannot reliably handle large intermittent power production fluctuations. Providing an autonomous, self-powered, and easily deployable meteorological sensor network can provide the tools to help mitigate this issue. With proper data [...]

Nextek is a pioneer in direct current (DC) power networks for buildings. The Nextek Direct Coupling® power distribution platform delivers superior efficiency, flexibility, and reliability to interior electrical circuits and on-site power generation. DC Systems; [...]

Bridging the Legacy and the Smart Grid: the Power Continuity Unit

Lank R., Trivedi S., DERP Technologies, LLC, US

In light of the massive storms that have hit the East Coast and the faltering reliability of the Grid, the need to add more distributed generation (DG) and to have more micro-grids is becoming increasingly [...]

Direct catalytic liquefaction of low-volatile hydrocarbons to clean light liquid fuels

Ganguli P.S., Energy Catalysis, Inc., US

Energy Catalysis, Inc. developed a direct catalytic liquefaction process for converting low-volatile heavy hydrocarbons such as coal, petroleum residuum, vacuum gas-oil, and tar sand bitumen into clean light liquid fuels. The technology concept was based [...]

Mobility of paramagnetic nanoparticles in porous media

Wang Y., Bagaria H., Zhang X., Johnson K., Abriola LM., Pennell KD., Tufts University, US

Stable paramagnetic nanoparticles were prepared and their mobility in reservoir matrix was measured as a function of particle mass loading, rate of sulfonate fraction in coating polymer, and the presence of surfactant.
