Computational Modeling of Ligands for Water Purification Nanocoatings

Vanka K., Houndonougbo Y., Lien N.R., Harris J.M., Farmen L.M., Johnson D.W., Laird B.B., Thompson W.H., University of Kansas, US

Electronic structure and molecular dynamics calculations are being used to investigate ligand-based nanocoatings for use in drinking water purification applications. The aim is to use computational chemistry to aid in the development of design principles [...]

Instantaneous Microbial Detection Demonstrated for Air & Water

Jiang J.P., McGill S., Morris S., BioVigilant Systems, Inc., US

Traditionally, growth based techniques have been the standard in environmental monitoring for evaluating the quality and quantity of microbial content. However, many studies have underscored the inadequacy of these techniques: (1) to provide environmental microbial [...]

Baltimore Charter on Sustainable Water Systems

Nelson V.I., Coalition for Alternative Wastewater Treatment, US

The Baltimore Charter on Sustainable Water Systems was drafted as a commitment to design new water systems that mimic and work with nature. These systems will both protect public health and safety and will restore [...]

Wastewater Effluent Total Nitrogen of 3 mg/l with Cost Effective, Low Maintenance Cluster Treatment System

Lombardo P., Lombardo Associates, Inc., US

Excessive nitrogen levels pose a threat to the ecological health of water resources in the United States due to excessive algal growth that causes ecological decline. The NitrexTM denitrification filter is a low cost, low [...]

Direct hydrothermal synthesis of LiMn2O4 spinel and lithium ion selective adsorption

Zhang Q-H, Sun S-Y, Li S-P, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Spinel LiMn2O4, in which the [Mn2O4] framework provides a three-dimensional interstitial space for Li+ transportation, shows excellent Li+ insertion and extrusion property from the Mn-O lattice. The lithium ion-sieve effect strongly depends on the crystal [...]

Water Purification Using Carbon Nanotubes

Cummings A., Seldon Technologies, Inc., US

As we learn more about the hundreds of contaminants common in water, the decline of our water infrastructure, and the potentially harmful effects of chemical treatments, it is not surprising that consumers are turning to [...]

Lombardo P., Lombardo Associates, Inc., US

The Malibu Creek Plaza is a shopping plaza consisting of both retail and commercial businesses, located in an environmentally sensitive area adjacent to the famous Surfrider Beach in Malibu, California. In 1999 the California Regional [...]

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 [...]

Off-Grid Fuel Cell System for High Power Quality Applications

Lima R.J.S., de Almeida A.T., Mendes A.M.S., Mendes A.M.S., Cardoso A.J.M., University of Coimbra, PT

There is a variety of critical loads, such as information technology, telecommunication, medical equipment and industrial process controls, which require high power quality. Conventional approaches to provide high power quality levels include battery based uninterruptible [...]

Improving Water Management in Fuel Cell Flow Channels via Oscillation of Water Droplets

Schultz R., Diebel J., Allen J., Michigan Technological University, US

To achieve maximum efficiency and reliability in a PEM fuel cell, a balance between keeping the membrane from becoming too dry or too wet must be monitored carefully. At present, product water is moved through [...]
