Optically active defects improve carbon nanotubes

The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of ...

Extracting information from ancient teeth

There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights ...

Synthesis of diamond-like carbon nanofiber film

An international team of researchers, led by Distinguished Professor Rodney S. Ruoff (Department of Chemistry) from the Center for Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) at ...

Researchers building a harder diamond, called pentadiamonds

Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed "pentadiamond" by its creators, may be useful for replacing current ...

Scientists investigate global spread of stinging jellyfish

"Get it off of me! Get it off of me!" shrieked Mary Carman, a marine ecologist at Woods Hole Oceanographic Institution (WHOI) as she flailed knee deep in the bath-like water of Farm Pond on Martha's Vineyard. She was observing ...
