A carefully manicured.
That spring is beautiful! Especially when you get up and already has itchy eyes and nose full of snot, it's all ... beautiful. But above all is mysterious, as the world around us, all full of mysteries that are waiting for a response to leave in peace to our restless minds. At least in the minds of some, since I have the feeling that there are some who just live to see Big Brother and other crap. It's nice to see people question and are interested in anything. It compresses like that ad that said ... "To the clouds that smell?" I, as I am, I started a series of mindsets to try to find the connection between the smell of a cloud and a napkin. I must admit that the conclusion it was not very satisfactory. But the nice thing is that it makes you wonder what they are made of clouds, how they behave, what kinds there are and all that stuff. Many who know me know my love of astronomy as an amateur astronomer I am, my biggest enemies are the clouds, but still I like the clouds, so today we will discuss the aerogels, to see that démontrer that.
Here is your cap Aerogel. Sure
clouds expected to speak, ha ha! If I am a master of suspense and surprises, both pleasant and unpleasant. But if I come to speak of Aerogel is for one simple reason. The reason is that it's damn funny and I want to have it in my house. You could say that Aerogel is the material of the future, as it has unique properties that make it the sea of \u200b\u200bcurious. Beginning with the first
curiously, its origin. This material looks as good in the photos, seems to have been taken from a alien spacecraft Saturday afternoon, but nothing further. Aerogel was discovered / invented by Samuel Stephens Kistler as a result of a bet between him and his colleague Charles Learned. Dealt bet on who could replace the liquid from a gas jar of jam without the bulk of this decrease. The result is the wonderful .. AEROGEL!.
The wonderful Aerogel thermal insulation.
Aerogel is a substance called collodion Coloide.Un is a substance composed of two phases. A continuous phase, usually smooth, and a dispersed particulate, usually solid. Well, in the aerogels, the continuous phase fluid which is usually water, is replaced by a gas, which is air and voila, Aerogel singing. Other celebrities are colloids, foam, aerosols, mayonnaise, etc etc.
Typically, the solid component used in the aerogels are silicates, but also constructed of zirconium, chromium oxide, alumina (also called corundum) tin and carbon.
In its solid state, the Aerogel seems totally out of a science fiction novel (remember the great Chief Hubbard). Its density is extremely low. On average, a cubic centimeters Aerogel weighs 3 milligrams. This may seem something a little abstract, but just imagine a cube or hexahedron made of Aerogel, with all sides measuring one meter. This is something great and think that will necessarily be heavy. But no! weigh no more than three measly pounds. This is because the Aerogel is basically air. On average, the Aerogel is composed of a 99.8% air and the rest is the material that is formed. Why so called "frozen smoke." This leads to a material that is extremely porous and gives him a unique insulating properties. It is an excellent insulator, as can be seen in the post dipuestas fotillos. This is because the network intrincadísima pores in the material, which prevents the heat to reach the other end. Totally awesome, as the flame, blue, has all the earmarks to be at over 1000 º C.
And do not light matches! that mystery!
is also reasonably strong, since as shown in the photo below, about 2.5 grams of aerogels, are capable of holding a brick without breaking a sweat weight 2.5lbs. This means that are capable of holding 1000 times its weight, but you have to endure much more, the order of 4000 times its weight. It all depends, of course, manufacturing.
absorbs the energy of a crash so that almost 90% of the crash energy is absorbed by the esturctura aerogels. It also absorbs toxic compounds in water, such as lead, mercury etc etc.
brutal force!
All advantages, no? So what the hell happens that my windows are not made of Aerogel and no longer made of Aerogel dirigibles? It turns out that the material fell into oblivion until he went to NASA, rather interested in its improvement and development. Airgel used in a fascinating mission, Stardust, in which a satellite, deployed a palette of Aerogel capture particles from comet Wild 2's tail. The mission ended successfully in 2004, when the samples arrived safely in the earth, but more of that another day.
Collector from the Stardust mission.
But until today, where still no flying cars, there is nothing Aerogel, there are only stupid like I can close this blog without a warrant for being "violated" copyright "or other government bullshit, as usual. Consider, dear friends, that rulers are stupid, and citizens are more or less heads thinking, but if a citizen becomes political, become hopelessly stupid (read Animal Farm). But better not to talk politics and say goodbye, with a smart move to hand, while waiting to start making cars Aerogel. And as it has much to do with the topic, I put a farewell video for a laugh and in general, and that laugh! I said!
