Scientists just got the first direct proof of stable carbyne - the world's strongest material

40 times stronger than diamond.
Elemental carbon is extremely versatile, and scientists have long been able to create new carbon allotropes that make for super durable and multi-functioning materials - such as everyone’s favourite material, graphene.
The 'carbon family' is one very resourceful family. But even with all these developments, carbyne remained elusive. In fact, it is the only form of carbon that has not been synthesised, even though researchers have been studying its properties for over 50 years.The reason for this is that carbyne is extremely unstable. This one-dimensional carbon chain was first discovered in 1885 by Adolf von Baeyer, who even stated that carbyne would remain elusive, as its high reactivity would always lead to its immediate destruction.
Carbyne’s mechanical properties are hypothesised to exceed all known materials. It’s assumed to be twice as stiff as graphene, 40 times stiffer than diamond, and have greater tensile strength than any other carbon material. With these kinds of properties, no wonder we’ve been trying to find ways to stabilise it.
And now, an international team of researchers have now found a way to mass-produce carbyne.
The team took two layers of graphene, pressed them together, and rolled them into thin, double-walled carbon nanotubes. The tubes were then wrapped around the atoms. These nanotubes protect the carbyne chains from meeting imminent doom.
Their research is published in the journal Nature Materials. 
Before their discovery, the record-holding number of carbon atoms in one continuous chain was 100. Now, the record has been broken with an astounding 6,400 atoms utilizing this novel method – and the chain continues to be stable.
Also, carbyne’s electrical properties increase with its chain length. This means that researchers will be able to experiment with the material more effectively with success from the nanotubes.
There is a huge wealth of possible applications using carbyne, and we’re excited to see what kinds of devices will arise with the delivery of this 'miracle' material.

There’s a Previously Undiscovered Organ in Your Body, And It Could Explain How Cancer Spreads

Ever heard of the interstitium? No? That’s OK, you’re not alone  —  scientists hadn’t either. Until recently. And, hey, guess what  —  you’ve got one! The interstitium is your newest organ. Scientists identified it for the first time because they are better able to observe living tissues at a microscopic scale, according to a recent study published  in  Scientific Reports , Scientists had long believed that connective tissue surrounding our organs was a thick, compact layer. That’s what they saw when they looked at it in the lab, outside the body, at least. But in a routine endoscopy (exploration of the gastrointestinal tract), a micro camera revealed something unexpected: When observed in a living body, the connective tissue turned out to be “an open, fluid-filled space supported by a lattice made of thick collagen bundles,” pathologist and study author Neil Theise  told  Research Gate . This network of channels is present throughout ...

20,000 megawatts under the sea: Oceanic steam engines

Jules Verne mused about getting energy from heat in the ocean  (Image: Marc Pagani/Getty) Jules Verne imagined this limitless power source in Victorian times – now 21st-century engineers say heat trapped in the oceans could provide electricity for the world IF ANY energy source is worthy of the name "steampunk", it is surely ocean thermal energy conversion. Victorian-era science fiction? Check: Jules Verne mused about its potential in  Twenty Thousand Leagues Under the Sea  in 1870. Mechanical, vaguely 19th-century technology? Check. Compelling candidate for renewable energy in a post-apocalyptic future? Tick that box as well. Claims for it have certainly been grandiose. In theory, ocean thermal energy conversion (OTEC) could provide  4000 times the world's energy needs in any given year , with neither pollution nor greenhouse gases to show for it. In the real world, however, it has long been written off as impractical. This year, a surprising number of pro...
