Carbon Structures from Pencils to Jetpacks

Рет қаралды 8,869

Күн бұрын

Buckyballs, nanotubes, and graphene sheets have been the way of the future for decades but so far, the science just hasn’t lived up to the hype. Yet there are new carbon structures that pop up about once a year claiming to be the next big thing. So… how far are we actually from carbon structures revolutionizing the world and finally bringing us jetpacks?

Graphene is great at conducting electricity, but if you cut the super thin sheets into ribbons - like for connecting parts on a computer chip - the ragged edges of the ribbon impede the electrons’ movement. So instead, some scientists deposited carbon right onto ridges of silicon carbide and found that the electrons moved along the edges “like light travels down an optical fiber.” One description described the movement as “ballistic.” It’s fast. Really fast. This could change everything… but that was 2014 and I’m still not taking a jetpack to work.

People rarely make ribbons by "cutting" them now. Nowaday you make ribbons "bottom-up" from depositing a molecule on a surface and allowing it to self-assemble in a 1D structure such that you don't get any ragged edges and hence can observe ballistic transport... Additionally, you can also open a bandgap in graphene nanoribbons and control the value by adjusting the width or edge structure.

This might be nitpicky, but diamonds are not the strongest known substance, but rather the hardest known substance. Diamonds are the best at cutting and scratching, but are actually very brittle when faced with hard impact.

One day we'll have to start talking about recycling all these devices that are full of graphene or carbon nanotubes. Carbon is abundant so recycling them is not necessary, but do we need to concern ourselves with the toxicity of any of these carbon structures (like we are worried about benzene) or their ability/lack thereof to break down in nature?

What about the carbon fiber rockets that are in use right now? You rarely hear about them and I have no clue why that is. It's incredibly strong, lightweight and used quite often in certain rockets made by certain company. I just thought that was something awesome that could be mentioned that most people don't know about.

I think the reason that we keep getting disappointed by the promises of these crazy new materials, is related to something I heard at an interview I had with a tech company (one with a few Ms in its name) a few years ago. The person I was talking with said that you can come up with lots of great materials that do great things, but if you can't figure out a way to make a mile of the stuff, it's not really all that useful

I don’t understand how graphene has chirality? Any single carbon would be bonded to four other carbons right? I feel a little foolish asking this but is it some sort of crystal structure, symmetry chirality?

Alex is a great science communicator and the worst (in a good way) person to pitch carbon based technologies if you want funding. If every new technology creator will take it takes it self less seriously, like Alex does here it will a better and funnier world. Cause common, unless you have good idea on what to do with tiny carbon football (not soccer) stop pitching it as life changing tech.
