Diver, Chemist Joins Pratt Faculty

For centuries, the forces of weather and winds have sent more than 500 ships to the bottom of the Atlantic Ocean off North Carolina’s coast. Some were also brought down by another terrifying force -- German U-boat torpedoes during the Second World War. Forty miles off the coast from Morehead City [...]

When Nano May Not Be Nano

DURHAM, N.C. – The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is. A new [...]

How Mercury Becomes Toxic in the Environment

DURHAM, N.C. – Naturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is dangerous to most living creatures. This finding is important, say Duke University environmental engineers [...]

Novel Approach Estimates Nanoparticles in Environment

DURHAM, N.C. Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health. Civil engineers at Duke University believe they have come up with a novel way of estimating how much of [...]
