Development of alumina/iron oxide nanocomposites as adsorbents for arsenic and fluoride removal from aqueous solutions: Process Optimization

Prathna T.C., Kumar Sharma S., Kennedy M., UNESCO-IHE, NL
The study was designed to optimize the process for the synthesis of alumina/ iron oxide nanocomposites and to investigate their potential as a sorbent to remove fluoride and arsenic from contaminated water. The nanocomposites had [...]

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 [...]

The Development of a Portable Arsenic Detector Based on Surface-Enhanced Raman Spectroscopy for Rapid on-Site Testing of Groundwater

Wang K.Q., Wang Y., Pan G., Wang K.Q., Wang Y., Agiltron, Inc., US
The combination of high toxicity and widespread occurrence has created a pressing need for effective monitoring of arsenic in groundwater. Although laboratory analysis has been used to measure arsenic in collected groundwater samples, the time [...]

Detection of Plant Cell Compartments and Changes in Cell Dielectric due to Arsenic Absorption via Traveling Wave Dielectrophoresis

Bunthawin S., Wanichapichart P., Tuantranont A., Membrane Science and Technology Research Center, TH
This study determined changes in cell dielectric properties due to variation of arsenic concentration of the cell suspending medium, from 1 to 150 ppm. An octa-pairs interdigitated electrode was used to induce dielectrophoresis, and the [...]

Atomistic Modeling of Arsenic Diffusion and Activation

Dunham S., Fastenko P., Qin Z., Henkelman G., University of Washington, US
Understanding the diffusion and activation of arsenic is critical for the formation of low resistance ultra-shallow junctions as required for nanoscale MOS devices. In this work, we combine the results of ab-initio calculations with continuum [...]
