New water filter kills disease-causing bacteria

19.11.2010
The latest episode in the American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions," focuses on development and successful initial tests of an inexpensive new filtering technology that kills up to 98 percent of disease-causing bacteria in water in just seconds without clogging.

The technology could aid many of the almost one billion people lacking access to clean, safe drinking water. A report on the work appears in the American Chemical Society's monthly journal Nano Letters.

Most water purifiers do their jobs by trapping bacteria in tiny pores of filter material. Pushing water through those filters, however, requires electric pumps and demands lots of energy. The filters also can get clogged, so they often have to be replaced. A new material developed by Yi Cui, Ph.D., of Stanford University could avoid many deficiencies of traditional filters. For starters, it does not trap bacteria like most technologies. It kills them outright.

"The removal of bacteria and other organisms from water is very important, not only for drinking and sanitation but also in industry as there's a frequent need to replace filters due to clogging," Cui says in the podcast. "The product we've developed could dramatically lower the cost of many filtration technologies for water as well as food, air, and pharmaceuticals, where the need to replace filters is common and very challenging."

This podcast is available without charge at iTunes and from ACS' Web site at www.acs.org/globalchallenges.

Global Challenges/Chemistry Solutions is a series of podcasts describing some of the 21st Century's most daunting problems, and how cutting-edge research in chemistry matters in the quest for solutions. Global Challenges is the centerpiece in an alliance on sustainability between ACS and the Royal Society of Chemistry. Global Challenges is a sweeping panorama of global challenges includes dilemmas such as providing a hungry, thirsty world with ample supplies of safe food and clean water; developing alternatives to petroleum to fuel society; preserving the environment and assuring a sustainable future for our children; and improving human health.

The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 161,000 members, ACS is the world's largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences. Its main offices are in Washington, D.C., and Columbus, Ohio.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
