Resistance and Potentiostatic Based Measurements of an Antibody Functionalized Conductive Polymer Coated Textile as a Biosensor

Bandremer A., Hebert A., Torosian S.D., Battacharyya D., Gleason K., McGraw S.K., Senecal A., Marek P., Food and Drug Administration, US

Effective food safety monitoring is challenged by the necessity to identify human infection capable microorganisms at sufficient infective doses and consumption levels. Regulatory agencies have developed methods for assessing food safety based on currently available [...]

Real-time monitoring of pathogens and nanomarkers in water by resonance laser spectroscopy techniques

Moguilnaya T.Yu., Bobkov P.V., Tomilin V.A., Kononenko E.B., JSC “SERVET-M”, RU

We develop a new method, allowing real-time monitoring of pathogens and DNA in water. The method is based on an analysis of radiation spectra in near-IR region. We have applied this method for rapid analysis [...]

Potential artifacts when evaluating the ecotoxicological effects of nanomaterials

Petersen E.J., Henry T.B., Zhao J., MacCuspie R.I., Kirschling T.L., Xing B., Dobrovolskaia M.A., Hackley V., White J.C., National Institute of Standards and Technology, US

Novel physicochemistries of engineered nanomaterials (ENMs) offer considerable commercial potential for new products and processes, but also the possibility of unforeseen and negative consequences upon ENM release into the environment. Investigations of ENM ecotoxicity have [...]

Assessment by Ames Test and Comet Assay of Toxicity Potential of Polymers Used to Develop a Field Capable Biosensor

Hebert A., Torosian S., Gleason K., Food and Drug Adminstration, US

Current methods of detecting food-borne pathogens take days to show and confirm results. There is a need for devices that decrease detection time. A field-capable rapid-detection device is being developed and in this study it [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]

More Efficient Hydrokinetic Turbines

Farb D., Pioneer Valley Renewables, US

Pioneer Valley Renewables applies fluid dynamic technologies to make a large advance in the performance of underwater river and tidal turbines--a synergy of unique fluid dynamic foil shapes with propeller blades that better direct the [...]

Autonomous Nanosensor System for Monitoring and Quantifying Arsenic in Water

Salinas S., Mosquera N., Yate L., Coy E., Yamhure G., González E., Pontificia Universidad Javeriana, CO

In present work, we have developed a system for detection and quantification of arsenic in water, based on surface plasmon resonance. The sensor uses a gold self-assembled monolayers on Au(111) substrate. Studies that we have [...]

Reducing Energy Footprint of a Waste Water Treatment Plant by Increasing Harvesting Efficiency of Solids following Primary Clarification

Lancaster C.D., Chang N., Kole A., Stephenson M., PARC, a Xerox company, US

This presentation describes a novel hydrodynamic separation (HDS) technology that has the potential to dramatically reduce the energy footprint of a wastewater treatment plant (WWTP) by reducing the energy required for aeration and by increasing [...]

Synthesis of nano-hydroxyapatite from a biogenic waste for the removal of manganese from wastewater

Amuda O.S., Sanni K.A., Kolawole L.L., Ladoke Akintola University of Technology, NG

A novel Hydroxyapatite nanopowder prepared from a biogenic waste, shell of a gastropod, by hydrothermal method was used for adsorption of manganese ion in wastewater. The nano-Hap produced was characterized using XRD, FTIR and SEM. [...]

Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]
