A group of scientists say they have created the Superman of metals, a material so strong and lightweight it could lead to the creation of faster vehicles and revolutionize the airline and automotive industries. Engineers at the University of California, Los Angeles, used a combination of ceramic silicon carbide nanoparticles and magnesium. The new metal boasts a stiffness-to-weight ratio that far surpasses other strong metals that engineers have reliably used for generations. The metal is also capable of absorbing and withstanding high heat without having its integrity altered. Nanoparticles are a tiny speck of any material, just 1 to 100 nanometer in size, or a billionth of a meter—not even close to being visible to the naked eye. When the material is scaled down to such a small size, its physical and chemical properties change. In this case, the silicon carbide nanoparticles were infused into a molten magnesium zinc. Silicon carbide is the hard ceramic material used for cutting blades. This “nanocomposite” metal is made up of approximately 14 percent silicon carbide and 86 percent magnesium by weight. “It's been proposed that nanoparticles could really enhance the strength of metals without damaging their plasticity, especially light metals like magnesium,” said Xiaochun Li, a professor of manufacturing and engineering at UCLA, in a press statement. “But no groups have been able to disperse ceramic nanoparticles in molten metals until now.” Magnesium is available in large quantities, meaning it would be easy to produce the material without damage to the environment. It is considered a type of load-bearing metal that is already used to make cars, albeit a weaker version. Correction: A previous version of this article inaccurately stated that an object with width between one and 100 namometers would be just barely visible to the naked eye. In fact, such an object would not be visible at all. By way of comparison, the diameter of a strand of human hair is in the range of 80,000 to 100,000 nanometersm, according to the National Nanotechnology Initiative Very interesting development. Sounds very promising. I would think it would have positive impact not only on cars, and airliners, but also on combat aircraft, and spacecraft.

They're going to build planes and cars out of hair?
You missed this part: By way of comparison, Si vis pacem, para bellum Those who beat their swords into plowshares will plow for those who don't Rebellion to tyrants is obedience to God.

Oops. My bad.
No problemo

I dunno. Magnesium is pretty flammable. Apparently, there are a vast collection of iPhone vids at YouBoob like this one where people try to destroy iPhones in new and unique ways.
Yes it is I was under the impression that under extreme heat magnesium burns so we are going to make cars out of an 86% flamable substance. I don't think we have thought this through. I had some magnesium wheels once they developed stress fractures
Alloys can have lower flammability: https://en.wikipedia.org/wiki/Magnesium_alloy
OK... so what happened to the zinc?
Magnesium filings or thin shavings oxidize very rapidly, but a larger/thicker piece is more chemically stable. Similarly, aluminum "dust" can be dangerously explosive... and even iron or steel wool can be ignited by a flame or electrical current...
are they going to call this new metal Adamantium ?

In a Cop Culture, the Bill of Rights Doesn’t Amount to Much Thanks, funny. I saved that to my collection of funny pictures. Happy New Year !

Wasn't than something that was obtained from ameteor? I thought they might call it unobtainium. I suspect that like many things created in a laboratory in small quantities it won't prove to be commercially obtainable
Wasn't than something that was obtained from ameteor? it's a fictional metal that they used in the comic book character Wolverine's skeleton .It is the metal in his claws . But I like the suggestion of Rearden steel better . Who is John Galt ? Quis custodiet ipsos custodes?
Beats me, use your google. I know what adamantium is according to fiction, I also know what unobtainium is according to fiction and no doubt you can find out what reardon steel is according to fiction just for your benefit Tom becuase I know you can't get past googling the constitution which is printed on a parchment made of unobtainium "in the realm of scientific wishful thinking, Unobtainium can refer to any substance needed that is critical to the plot of a science fiction story, but which does not exist in the universe as we know it. In other words, total bullshit"
'Who is John Galt ? 'was a rhetorical question by me ,but one of the most famous lines in literature . Rearden steel is also a fictional steel from the same book by one of the most famous authors of the 20th Century .Suggest you use Google yourself .
Quis custodiet ipsos custodes?
Tom do you think we are backwoods hicks down here of course we have read Ann Rand, required reading for any democratically minded person who wants an exposee of the system, besides the book market is controlled by overseas publishers just like everything else

Magnesium is pretty flammable.
and of course, alkali metals like sodium, lithium & potassium are all highly flamable when exposed to air/water...

“Truth is treason in the empire of lies.” - Ron Paul
Americans who have no experience with, or knowledge of, tyranny believe that only terrorists will experience the unchecked power of the state. They will believe this until it happens to them, or their children, or their friends.
