Scientists have designed a new type of carbon that is harder and
brighter than naturally formed diamonds.
For those who want to wear a one-of-a-kind sparkler on their
fingers, the new material, called Q-carbon, also gives off a soft glow.
"This new phase is very unique," said study co-author
Jagdish Narayan, a materials scientist at North Carolina State University.
"It has novel electrical, optical and magnetic properties."
For instance, the material can act as either a metal or a semiconductor, and is magnetic at room temperature.
Heat and pressure :- Despite being one of the
most ubiquitous and iconic symbols of wealth and luxury, scientists still don't
fully understand how diamonds are
formed. Most think the diamonds mined today formed between 1 billion and 3
billion years ago, at a depth of about 62 miles (100 kilometers) below the
Earth's surface, researchers
previously told Live Science.
