Electrospun TiO2 nanofibers for gas sensing applications

Kim D.Y., Kim I-D, Rothschild A., Tuller H.L., Kim D.Y., Kim I-D, Jo S.M., Korea Institute of Science and Technology, KR

TiO2 fiber mats were deposited onto Al2O3 substrates with interdigitated Pt electrodes by means of electrospinning from a solution of DMF and PVAc synthesized using bulk radical polymerization of titanium propoxide and acetic acid as [...]

Wireless Micro and Nano Sensors for Physiological and Environmental Monitoring

Kaminska B., Simon Fraser University, CA

A wearable physiological/environmental monitoring system and a practical implementation are presented. The technical requirements for wearable electronics and sensors have been specified with an example of ECG, oxygenometer, and wireless network-based bidirectional communication. A presented [...]

Investigating the Benefit-Cost of MEMS Application for Structural Health Monitoring of Transportation Infrastructure

Jha M.K., Davy A.B., Morgan State University, US

This paper develops a fuzzy-logic based procedure for quantitative cost and benefit calculation of MEMS application for structural health monitoring of transportation infrastructure. This will be a major step forward for widespread MEMS application in [...]

Microbial fuel cell

Willert-Porada M., Lorenz K., Freitag R., Jerome V., Peiffer S., University of Bayreuth, DE

Polymer electrolyte fuel cells, PE-FC, use hydrogen or methanol as fuel. Water soluble organic compounds, like starch, glucose, acetates, can not serve as fuel because of limited catalytic activity of common metal catalysts. Opposite to [...]

Electrochemical ‘Lab-on-a-Chip’ for Toxicity Detection in Water

Popovtzer R., Neufeld T., Ron E.Z., Rishpon J., Shacham-Diamand Y., Tel Aviv University, IL

An electrochemical Nano-Bio-Chip for water toxicity detection is presented. Integrating living cells with electronic devices contributes functional information regarding the effect of toxicants on living organisms. Bacteria, which have been genetically engineered to respond to [...]

Layer by Layer Fabrication of an Amperometric Nanocomposite Biosensor for Sulfite

Adeloju S.B., Ohanessian A., Water and Sensor Research Group, AU

This paper will present the results of a layer by layer strategy that we have developed for the fabrication of a polypyrrole nanocomposite amperometric biosensor for sulfite. The use of this strategy to fabricate bilayer [...]

Hydroxyapatite-imidazole-polymer composite films as a proton conductor under no humidified condition

Tsutsumi H., Hisha Y., Yamaguchi University, JP

We prepared the proton conduction system, hydroxyapatite (HAp)-imidazole (Im)-polymer composite films and investigated their structure, conduction behavior and mechanical properties. HAp particles used in our investigation were prepared with two different ways, a-HAp and n-HAp. [...]

Molecular Simulation Studies on Adsorption of Mercuric Chloride

Kotdawala R.R., Kazantzis N., Thompson R.W., Worcester Polytechnic Institute, US

The need to develop technologies capable of achieving high removal efficiencies for mercury chloride emission control led many researchers to focus their attention on the evaluation of the adsorption capacity and selectivity shown by different [...]

Determination of Pore Size Distribution of Nafion/Sulfated beta-Cyclodextrin

Jeon J-D, Lee B.H., Kwak S-Y, Seoul National Univesity, KR

Direct methanol fuel cells are promising candidates for portable power sources and transport applications. One of the critical problems hindering the commercialization of DMFCs is high methanol permeation rate across proton-exchange membranes. In this study, [...]
