In March 2010, researchers from Rice University in Houston traveled to to Guanajuato, Mexico, to conduct field tests on a new nanotechnology for removing arsenic from drinking water. The system uses nanoscale magnetite, or nanorust. The tests are some of the first that attempt to move nanotechnology beyond the laboratory and into the real world. The ongoing research by Rice's Center for Biological and Environmental Nanotechnology (CBEN) is funded by the National Science Foundation.

A piece of chemically treated cotton cloth is able to separate crude oil from sea water (both from Mexico Gulf) completely within seconds by using gravity alone. It can be developed into various effective tools for cleaning up the oil spill in Mexico Gulf. The treated cloth allows water to path through but not oil. The novel surface chemical treatment method is developed by University of Pittsburgh.

The health and environmental effects of carbon nanoparticles, which are widely used in electronics and medicine, are not well understood. Researchers at Brown University have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae.

IBM has unveiled a novel nanomembrane technology that stands to alleviate the growing shortage of drinkable water worldwide. Scientists at IBM Research, together with collaborators from Central Glass, the King Abdul Aziz City for Science and Technology, and the University of Texas, Austin have created a new membrane that filters out salts as well as potentially harmful toxins in water such as arsenic while using less energy than other forms of water purification.

Scientists and engineers are collaborating across disciplines to develop and network miniaturized intelligent nanosensors that can rapidly and remotely detect change in their surroundings. These sensors have a wide range of potential applications: environmental, medical, military and transportation. This workshop will focus on revealing the chemistry and physics behind the creation and application of these sensors.

Radiant Shield Coating (RSC) by Hyperion Environmental uses the power of light to keep building exteriors clean. Over time, abrasive methods like power washing can damage surfaces beyond repair and harsh chemicals harm the environment. Radiant Shield is environmentally friendly and can last years with just one application. Continually re-energized under direct or ambient sunlight, RSC destroys organic contaminants before they accumulate, keeping buildings cleaner, longer than ever before.

Nano-sized particles of silver are terrific at fighting bacteria and mold, and are being used in hospital settings and for food storage. But they're also being incorporated into more casual types of consumer products, like children's toys and clothing. Could this lead to a harmful accumulation of nano silver in our wastewater treatment plants and in our rivers and streams?
