Related: About this forumThere's a New Blackest Material Ever, and It's Eating a Diamond As We Speak
By Brandon Specktor - Senior Writer 5 hours ago Tech
It's so black, it turns diamonds into "black holes."
A new exhibition in New York turns a sparkling yellow diamond (left) into a veritable black hole (right) thanks to the blackest material ever created.(Image: © R. Capanna, A. Berlato, and A. Pinato)
On the floor of the New York Stock Exchange, a team of artists and scientists have made a 16.78-carat diamond valued at more than $2 million disappear.
Granted, denizens of the Stock Exchange are no strangers to making vast amounts of wealth vanish, but this time the scientists are doing the heavy lifting. Working with artist Diemut Strebe, a team of researchers from MIT covered the shimmering yellow diamond in a newly discovered type of carbon nanotube coating that turns 3D objects into black, almost 100% light-free voids.
According to the researchers, who described the coating in a study published Sept. 12 in the journal ACS Applied Materials & Interfaces, this newfound nanotube structure is the blackest of black materials ever created, absorbing more than 99.996% of any light that touches it.
"Our material is 10 times blacker than anything that's ever been reported," lead study author Brian Wardle, a professor of aeronautics and astronautics at MIT, said in a statement.

What makes this material so special?
