On the level of the New York Stock Exchange , a team of artists and scientists have made a 16.78 - carat diamond — prize at more than $ 2 million — melt .
Granted , denizens of the Stock Exchange are no strangers to makingvast amounts of riches vanish , but this sentence the scientists are doing the heavy lifting . Working with artist Diemut Strebe , a team of researchers from MIT hide the shimmering yellowish diamond in a newly chance upon type of carbon carbon nanotube coat that turns 3D objects into dark , almost 100 % scant - free nothingness .
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.
According to the researchers , who described the finishing in a study published Sept. 12 in the journalACS Applied Materials & Interfaces , this newfound carbon nanotube complex body part is the blackest of black materials ever created , absorbing more than 99.996 % of any light that tint it .
" Our material is 10 times black than anything that ’s ever been report , " lead work author Brian Wardle , a prof of astronautics and astronautics at MIT , said in a statement .

The squad created the new coating by chance , while seek to contrive an improved unconscious process for growingcarbon nanotubes(essentially , microscopically small strings of carbon paper ) on aerofoil like aluminum foil . One job with work with aluminum , they found , is that a layer of oxides form whenever the surface was exposed to open air , make a plaguey chemical substance barrier between the nanotubes and the foil . To eliminate these oxide , the squad soaked the enhancer in saltwater , then moved it into a minuscule oven where the nanotubes could grow without oxygen intervention .
With millions of tangled nanotubes now constellate the foil like a microscopical forest of pelt , incomingphotonsof light got lost and had a very hard time exiting from the transparency ’s surface . The foil , the squad found , had thus turned whole smutty — so bootleg , the ridges of the aluminum were wholly invisible when viewed directly on .
" I retrieve noticing how dim it was before growing C carbon nanotube on it , and then after growth , it count even blue , " study Colorado - author Kehang Cui , a prof at Shanghai Jiao Tong University , state in the statement . " So , I thought I should measure the visual reflectivity of the sample . "
Cui and confrere compared the reflectiveness of their new finishing with other light - raven nanostructures , including the previousrecord holder for dark , Vantablack . While the deviation between the various nanostructures are paltry to human eye , the investigator found that their covering was indeed blacker than every other Black person they tested , no matter the angle at which light reach the coating .
The essence , as you could see in the image of the diamond above , is eerie . Once exposed to the coating , the brilliant white-livered diamond seemingly loses all of its facet , flatten intowhat artist Diemut Strebe called"a kind ofblack mess " from which no luminousness or shadows can escape .
Incidentally , this uberdark coating could one mean solar day be used to help oneself stargazer see genuine dim holes , by enforce the fabric to telescope - mount shades that help reduce glare from the stars . For now , though , you may see the diamond - shaped void for yourself at the New York Stock Exchange until Nov. 25 .
