Fiction | Five industrial materials that can change the future
Over the past few years, mankind has invented a whole bunch of different technologies, devices and gadgets. However, the most important component that puts into question the practice of the invention, in practice, is the production material that makes up these things, and without which it is impossible to implement certain ideas. Please find a selection of the five most insane, newly invented materials that are designed to change the future because of their potential use and possible use are virtually limitless.
Aluminum foil bubble
The material, invented by a team of engineers from the University of North Carolina, may be very useful in the production of protective equipment and packing goods. For its production, scientists take aluminum sheet is rolled thereon ribbed roller to create a uniform depressions fill these recesses foaming agent such calcium carbonate or hydrate Tinat, placed on the same second sheet is rolled and placed in a furnace. The high temperature starts foaming and finally in place these “bubbles” are formed air gaps.
Further production tests have confirmed that this metal weighs 30 percent less than conventional sheets, at the same time, it is almost 50 percent stronger and much better absorb the impact of external energy to it. Furthermore, the production cost of such material is not too high, compared with conventional. In this field of application is almost incalculable: from the production of cargo containers, packaging for fragile items to production of bicycle helmets.
By connecting the polyurethane sponge titanium powder and special binders that scientists have the opportunity to create a metal material, in form resembling a sponge (or foam). In the production of the main frame and polyurethane foam evaporates as a result of the titanium turns a kind of “foam” design, which was subsequently under the influence of temperature can be provided with additional desirable properties and forms.
The final properties will thus depend on the porosity of such sponge. But the most basic – its strength and incredible ease – will remain. Dishes such a sponge, of course, not pomoesh, but to apply the material as the production of artificial bone substitutes seems ideal to use it. First, the material in its mechanical properties substantially identical to bone tissue, and secondly, because of the porosity, this bone can live in the material literally grow into. In general, the real “Wolverine” very soon in your city.
Just a couple of months ago, this stuff knocked out the title of the lightest material in the world. Prior to that, in the palm of this property was owned aerografitu, whose density is 0.18 mg/cm3. In turn, the density of the newly developed graphene airgel is only 0.16 mg/cm3, which is lower than that of helium and only two times lower than that of hydrogen. Graphene airgel literally can “float” in the air.
Aerogel has been created through the use of freeze-drying (pre-frozen and then follow vysushki in a vacuum) of interconnected carbon nanotubes and graphene. The result is an incredibly lightweight material with remarkable strength and elasticity. Its absorbent properties affect not smaller – material capable to absorb a variety of organic substances in a total of 900 times its own weight. When and if the graphene airgel will become more accessible, it is perfectly cope with the role of an insulating material and is an excellent tool for data collection, such as oil spills.
Artificial spider silk
Silk is amazingly durable natural material, but to extract it not as easy as it seems. Therefore, the Japanese start-up company Spiber decided to develop a method for the production of synthetic versions of this material. Companies were able to determine the fibroin gene, a key component that allows web spiders produce.
Having determined the gene, the company has created a way of bioengineered bacteria that can produce silk is incredibly fast. Moreover, this approach has opened Spiber ability to create new types of silk in a very short period of time, literally within 10 days from the start of development to implement it into production. When the bacterium is not very demanding for food, feeds on sugar, salt and other trace elements. When it produces the special protein which engineers ground into powder, then it is created from the material of which it is possible to make not only the skin, but give generally any desired shape. One gram of fibroin with enough to produce 9 km of silk thread.
By 2015 Spiber plans to create 10 metric tons of this wonderful material.
If you at least once glued my fingers with superglue, you probably know how painful they will then tear off each other. Now imagine that your fingers are stuck together at the molecular level! Unstick them will be much more painful. So, a group of researchers from the University of Oxford, inspired by the bacteria Streptococcus pyogenes opportunities to cling to other cells, created on the basis of this principle, a new molecular superglue.
It is produced in bacteria, scientists took one kind of protein, the one that is responsible for the adhesion to human cells and used it to come up with the glue that creates in contact with neighboring cells bond at the atomic level. Contact this gives is so strong that, in laboratory testing equipment on which the tests were conducted, broken faster than the glue was able to withstand this.
Now, scientists still find a way to connect with other selected protein molecular structures that will create a heavy-duty types of selective adhesive that will not be glued our fingers.
