Grant to Further Study Nanotechnology’s Environmental Impact
How are nanomaterials affecting the environment—and us? With a new grant renewal, CEINT researchers seek answers. The nanomaterials revolution has made these exceedingly tiny engineered particles a hot commodity, used in products from clothing to sunscreen to electronics. But the very properties that make them so useful – vanishingly small size and high surface area – may have unintended consequences as they enter living organisms and the environment.

Emissions of Pollutants from Nanowaste Incineration
Disposal of waste through incineration produces hazardous pollutants. Among them, polycyclic aromatic hydrocarbons (PAHs) and chlorinated dioxins and furans are of concern, as some of them can induce cancer, can cause mutations in genetic material, and can interfere with the proper functioning of [...]

Sediment Biogeochemistry Model wins Best Poster
In the long run, most of the nanosilver that will enter aquatic environments will end up in river and lake sediments, so it is important to know what happens to the silver nanoparticles in these sediments. Amy Dale, a Ph.D. student CEINT affiliate at Carnegie Mellon University has developed the [...]
