Oh... I guess I found out about as much as find-out-able.
Our two-step process involves the partial removal of lignin and hemicellulose from the natural wood via a boiling process in an aqueous mixture of NaOH and Na2SO3 followed by hot-pressing, leading to the total collapse of cell walls and the complete densification of the natural wood with highly aligned cellulose nanofibres. This strategy is shown to be universally effective for various species of wood. Our processed wood has a specific strength higher than that of most structural metals and alloys, making it a low-cost, high-performance, lightweight alternative. -Source
So... Science FTW!... yay!!!

Yeah, that's all great and all, but what about flammability and heat tolerance?
Wood's never been too great in those departments

To be completely fair, neither has aluminum or magnesium, which rhyme with titanium.

FTFA: "This new way to treat wood makes it 12 times stronger than natural wood and 10 times tougher,"

And, I'm guessing, 12 times more flammable.

"The most outstanding observation, in my view, is the existence of a limiting concentration of lignin, the glue between wood cells, to maximize the mechanical performance of the densified wood. Too little or too much removal lower the strength compared to a maximum value achieved at intermediate or partial lignin removal. This reveals the subtle balance between hydrogen bonding and the adhesion imparted by such polyphenolic compound. Moreover, of outstanding interest, is the fact that that wood densification leads to both, increased strength and toughness, two properties that usually offset each other," said Orlando J. Rojas, a professor at Aalto University in Finland who does not speak, English.

Engineers at the University of Maryland, College Park (UMD) have found a way to make wood more than 10 times times stronger and tougher than before, creating a natural substance that is stronger than many titanium alloys.

So is this like exponentially stronger? 1010, maybe?

A guitar made out of wood would be a very interesting new thing... Are you ready to break into new frontiers? :-)

Fine with me, as long as this doesn't turn into some excuse to ramp up logging.

It mentions in the article that you can use *any* wood for this - even balsa wood which is very fast-growing.

Magnesium is highly flammable.  Titanium is also pretty flammable.

Machining and welding them are a biatch.

/the fun thing about magnesium fires is that water makes it burn hotter

Based upon their methods, it sounds like they really are driving towards compacted cellulose molecules. That's all well and good, but there's probably ways to use scrub weeds and other sources of cellulose, denature the cell walls in a way that leaves the cellulose molecules largely intact (but free to move in a solution), filter, and then compact the cellulose / squeeze out the solution to result in something even better than this material. I suspect that someone here on Fark even knows about such a process, and can point us to such a material.

blah blah blah

"It is both strong and tough, which is a combination not usually found in nature,"


Oh? Not usually found in nature? Like your treated wood, you dolt?

Seriously though... Wood is an awesome material. If these maniacs have come up with a way to make it superior to current materials... Well, that's fan-freakin'-tastic.

Hmm, on one hand it's a grass, but on the other hand it still has lignin so a similar process might work since on a quick read of destructor's previous info it's basically boiling it in certain chemicals to remove all but a specific amount of lignin and then hot pressing it to increase density. Maybe hemp would work too.

Thing of it is, Bamboo has a goofy vascular system. So this process probably won't work with it since it doesn't have a favorable lignin/cellulose ratio.
