The Nano Road to Energy Efficiency

Science Daily reports: Researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a new way to apply nanostructure coatings to make heat transfer far more efficient, with important potential applications to high tech devices as well as the conventional heating and cooling industry. These coatings can remove heat four times faster …


What’s in Your Toothpaste?

A new UCLA study raises health concerns about a nanomaterial found in a broad range of consumer products.  Nanoscale titanium dioxide, which is used in toothpaste, sunscreen, paint, cosmetics, vitamins, food coloring, and nutritional supplements, has not been extensively studied for its toxicological properties.  A team lead by Robert Schiestl, a professor of pathology, radiation oncology …


One Step Backward, One Nano Step Forward. . . Maybe

The action on nanomaterials continued at the federal level in August, advancing forward in one area (tentatively) and faltering in another (perhaps temporarily).  First, on August 4, the Interagency Testing Committee (ITC) issued its 64th report.  (The ITC is an independent advisory committee charged with identifying potentially toxic chemicals for which there is inadequate testing …


Nanopolicy Bumps in California

California continues to lead the way nationally on nanotechnology regulation, despite some bumps along the way.  Most recently, the Department of Toxic Substances Control issued a request for information regarding analytical test methods, fate and transport in the environment, and other relevant information from manufacturers of reactive nanometal oxides.   Substances covered include aluminum oxide, silicon …


Getting Serious About Toxicity Testing

Most of the products we use everyday contain chemicals that have never undergone meaningful health and safety testing.  That statement is hardly controversial; most folks on all sides of the continuing debate over chemical policy reform accept it as accurate.  Yet there is controversy over whether such testing should be required as a routine matter …
