A new generation of water filtration materials is enabling municipalities and industries in the United States and water-short countries overseas to produce safe drinking water from supplies contaminated with salts and other undesirable compounds, according to an article scheduled for the April 23 issue of Chemical & Engineering News, ACS' weekly newsmagazine.

DNA-wrapped single-walled carbon nanotubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards and Technology (NIST). The results of their laboratory studies appear in an upcoming issue of Advanced Materials.
