What new materials are there?

One person's waste is another's resource.

Today’s carbon-based supercapacitors are expensive, but recently scientists at Imperial College London have found that they can use lignin to replace the graphene-based carbon used in supercapacitors today. The lignin-derived material can store more electrical energy for a given volume than carbon-based components and it is cheaper.

Finnish company Stora Enso is piloting production of a sustainable graphite replacement for lithium ion battery anodes made from lignin. Range and performance are as much about weight reduction as power and energy storage.



A year later:

Northvolt will use Stora Enso’s lignin-based hard carbon anode material, Lignode, to produce battery cells and ultimately a sustainable battery made from raw materials sourced from Nordic forests. When the battery goes into production, it will be the first to be made entirely from European raw materials on an industrial scale.

 
Once again, nature has the answer . . .

cheers,
Robin.

And now you can get the plastic out of exhaust

Would very much be interested to know more.
 
Planes that take too long to service need to start being phased out, not continue serial production...sorry.. if this character is correct it is too expensive and time consuming to keep these sculptures flying as they are. unrealistic expectations all around as usual.

If this ceramic stuff is practicable then one would hope Congress will know and start taking measures.
 
Related to that topic. Spray-on clothes were described by Stanisław Lem in Return from the Stars in 1961, over sixty years ago. (About that time he was also writing about swarming nanobots, VR and AI-produced literature and art.)



Some of the images are probably NSFW.

Outside the world of fashion, I can think of other applications for the technology - seamless hazmat suits for example (apart from the headpiece). Some known problems are lunar dust, which is highly abrasive, and Martian dust, which is rich in toxic perchlorates. A spray-on single-use outer coat for spacesuits could be a solution.

From phys.org "Heat-proof chaotic carbides could revolutionize aerospace technology." It can stir steel....good to 7000 degrees. This is a big one, guys.
Do you have a link?

I wonder what the other physical properties are? Not much use if it’s brittle.
 
 

Where have we heard this before.
 
OK, this is paywalled, but pretty astonishing. 100-fold improvement in shielding? Really?


A bit of googling and...


This refers to radiation-resistant aluminium alloy, not explicitly shielding the occupants within, so you might find the headline a little misleading. In essence, metals degrade over time when exposed to radiation, becoming brittle (a problem anticipated for commercial fusion reactors). This stuff is apparently very resistant to that effect.

Want to land on Mars?---just crash
After many years of research, NASA has finally found the right answer.:)

Nothing.

The perfect material. See 'It Was Nothing - Really!' A very funny story by Theodore Sturgeon.


Noting that toilet paper never tears right across the perforation, then...

... if, in these special cases, the substance becomes stronger when a small part of it is removed, it would seem logical to assume that if still more were removed, the substance would be stronger still. And carried to its logical conclusion, it would seem reasonable to hypothesize that by removing more and more material, the resulting substance would become stronger and stronger until at last we would produce a substance composed of nothing at all - which would be indestructible!

Can we please build spacecraft with sharp noses and wings now? Aww…
