Brown University researchers have discovered a nanomaterial that can absorb the mercury emitted from a broken compact fluorescent lamp (CFL). The researchers, led by Robert Hurt, professor of engineering, and engineering student Natalie Johnson, have created a mercury-absorbent container lining that can be used commercially.

New ORNL process brings nanoparticles into focus

harminka — Tue, 24 Jun 2008 03:54:25 -0500

Scientists can study the biological impacts of engineered nanomaterials on cells within the body with greater resolution than ever because of a procedure developed by researchers at the Department of Energy's Oak Ridge National Laboratory.

Measuring movement of nanomaterials in simple model food chain

harminka — Sat, 31 May 2008 03:38:31 -0500

New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.
