What is the first hard thing in the world

Introduction of carbon alkynes

Carbon alkynes are carbon chains formed by many carbon atoms gathered together, and the carbon atoms are connected by single, double and triple bonds. It has been proven to be the strongest material in the world, and its strength is more than 200 times stronger than steel. Until the discovery of carbynes, we thought that the hardest thing in the world was diamond, but diamond is much less strong than carbynes, a full 40 times less strong. Carbon alkynes are harder than all other carbon substances.

The carbonyne debate

Astronomers have always felt that they have found a signal for the existence of carbynes in the vast universe, while chemists have been arguing about the possibility of synthesizing carbynes on Earth. It was only when scientists synthesized a chain of 44 carbon atoms that the debate stopped and all was quiet. In 2016, a team of researchers found a way to mass-produce carbonyne chains by taking double-walled carbon nanotubes and generating carbon chains that do not break down easily. The length of carbon chains generated with this method also set a record.

Properties of carbonyls

The properties of carbonyls are interesting in that they have the same flexibility as polymers and double-stranded DNA. Its rotational strength is determined by the solidity of its terminal chemical composition, and if the carbonyne is twisted or bent, its overall structure is able to rotate with it. The stability of carbynes is probably its most interesting property. Recent studies have found that if two carbynes chains come into contact, they react, but there is a barrier that activates the reaction, acting as a wall between the reactions and preventing them from occurring very easily.
