Boron nitride nanotube: Tiny tube with great potential | Catharine Fay | TEDxArendal

[@mattgraham2473]

Take a look at PPK (ASX) stock in Australia, its skyrocketing as Deakin University has found a way to continuously produce BNNT and PPK has the license to commercialise it. BNNT's are the 4th Industrial revolution

[@massaddress]

What a time to be alive.

[@toamaori]

BNNT composite ceramics are going to be very useful for our future

[@cupajoesir]

is it just me or does this seem like a bnnt infomercial?

[@Peace2051]

I'm surprised there's no comment below about hypersonic cruise missiles as being an early adopter of this technology. They go about Mach 5 and are a game changer to counteract the effectiveness of aircraft carrier task forces. But I'm glad there appears to be more benign applications. How stable are these structures and will they be the next wave of pollutant? Remember asbestos was useful but never breaks down and that's why it irritates the body when ingested or breathed in. So this promo video is very informative but also very one-sided.

This is fantastic. I was not aware, that a material, other than something like lead, could block radiation. I would like to invest in this.

[@MrMonkeybat]

Any material blocks radiation. Lead is often used because it is dense so takes up less space. To block radiation you need as much stuff as you can get between you and the source.

[@VFusioN69]

second hardest after diamond

[@Bassotronics]

The nanotubes are strong but the overall structure is an incoherent mess. If we could organize those nanotubes like the structure of cardboard box material, you’ll hit the structure jackpot.

[@theopinion367]

applicable in space

[@diortoop]

Thanks

[@bungercolumbus]

are they the same thing as hydrogenated boron nitride nanotubes?

[@mikethespike056]

No, those are hydrogenated.

[@just1certifiable]

The opportunity to make materials for aircraft and spacecraft? How about turning humans into cyborgs, did you envision that also?

[@jimtheedcguy4313]

Take a shot every time she says bnnt.

[@CarlJohnson-wk3rv]

Jim The EDC Guy ahahahahaha

[@arlaban22]

Can it stop a bullet? ...is it better than kelvar ?

[@spasegeek9214]

30x stronger than kevlar

Cost of Boron vs Graphene

[@Seekerofknowledges]

I am throwing a bottle in the sea here in the hope of getting someone to help me answer some of the questions I have about this wonder material. I am just a man with zero notion of chemistry and material science, but meanwhile I am possessed with the idea of starting my own small series electric car boutique. I am looking for a material or composites that can allow me to build the world lightest, stiffest and strongest possible car chassis ever built. Ideally weighting less than 30kg. I am aware that this will cost a kidney but extreme light-weighting is a must for me to achieve the speed record I am targeting. Hopefully someone out here can help. Thank you in advance

[@RetroDanceMonsterxX]

I’m not an expert in BNNT but I am doing my MSc thesis on 2D hexagonal boron nitride, so flat version of what she mentions. It is very similar to graphene both in atomic structure and bulk stacking. Picture a pencil, the pencil lead is made of Graphene, essentially carbon 2d layers. Graphene is one of the strongest materials because of the hexagonal atomic structure. But pencil lead is soft, that’s because the strength is in the flat bonds, between two layers however, the bonds are weak so the layers slide off each other. One difference between h-BN (hexagonal boron nitride) and graphene is that graphene is a conductor while h-BN is a widegap semiconductor. This means that h-BN acts like an insulator but under high temperatures or electric fields it acts like a semiconductor. h-BN is also a great heat conductor. I don’t know how good or strong it would be for cars but since BN structures are very similar to carbon structures (e.g. diamond, graphene) it is worth researching whether or not it can be used similarly to carbon fiber and whether it would have any advantages. Hope this helps, good luck!

[@maldenbarisic4002]

Can BNN be ,if threaded,used to make ropes for Space Elevator?They are ligtweigt and 100 times stronger from Steel,as said in this video.

[@JohnDoe-kq8hz]

I wonder, could this process of making BNNT be used to make other nano tubes..? If so, possibilities would be endless.. how about combining titanium, carbon and some super-conducting matterial into nano tubes.. or combining matterials that are on the top of heat/cold, radiation, gas and chemical ressistance, as well as ultra strong, light weight, and some other properties.. would it mesh into nano tubes with all those properties..? Or do matterials lose their curent properties once they're in nano scale..? DNNT is interesting because it seems that production is quite simple and very cheap, which could easilly find its way into mass industry.. I wonder if other nano tubes uses similar production methods..? From shat I understand it has to be different from how for example carbon nano tubes are produced, because acording to concensus it is too expensive for industrial use.. if its production is in any way similar to DNNT's, then I'm not sure where those production costs would be coming from.. sure you'd need specialised facilities to produce nano tube composites structured and shaped to specific needs, such as building an airplane, or producing specific parts for vehicles/boats, buildings, machinery etc.. Simply put, if producing any type of nano tubes isn't as complex as moving individual atoms to form specific paterns, then I'm not entirelly sure why industry doesn't catch up.. then again, having cars and machines harder to break would mean less sales, so perhaps it's not so strange after all.. :-)

[@mikethespike056]

I think they're pretty difficult to make. Ask the NASA Langley Research Center. They made them.

[@manuj9861]

Nice speaking make subject easy to understand. Like this video

[@ReallyNo.01]

So how does this degrade? We could be making abestos.

[@PeterTysdal]

I want to wear it

[@MarianoNappi]

The lunar module was made of a "special" aluminum and all astronauts who stayed on the moon suffered nothing. Why do you have to build such a special ship now?

[@alanshibuqut6638]

Do you realise that the moon is only 384, 400km away thus the radiation levels aren't that dangerous. The distance to planets like mars is millions of kilometres away thus the risk of radiation increases. To sum it up the further we travel away from earth the more dangerous the radiation levels. Which is why we need efficient shielding materials like Hydrogenated BNNts

[@tonito_69]

"a special aluminum"??? Oh, yes... very special... Unfortunately, NASA lost that advanced and special aluminum foil "technology."...

[@khan92asif]

Graphene or bnnt

[@ginger_nosoul]

Graphene is the harder material but bnnt is easier to produce and it get most jobs done, thats how i understand it anyway.

[@malizaar4114]

Graphene..?

[@JesseGilbride]

What CAN'T it do??

[@sonjaONeill]

clean up the leaking fusion reactors here on earth?

[@Polemicist_]

Ahhh, but you can use BNNT as an insulator for the electronics that go into particle accelerators, which can be used to split uranium, reducing its half-life.

[@anoaboadosaro]

@@sonjaONeill fusion?

[@xafar67]

Make a comment from a vegan interesting

[@RynaxAlien]

Boron nitride nanotube bicycle frames? Or space elevator cable? Cancer can be prevented by choosing healthier lifestyle and vegan diet.

[@zenapoo1]

Yes, how about using it for the good of humans and the planet instead of destroying ?!

[@synexiasaturnds727yearsago7]

Add some carbon nanotubes in

[@bungercolumbus]

can you build a solid wall out of this?

[@sachinpatare5887]

Yes

[@mikethespike056]

Yes.

And these mainstream doctors tell me my condition is delusional 😞 my morgellons is very real , the fibres growing under my skin are very real and alive , I'm beginning to think they tested their experiment on me .
