Hybrid material “Proteus” cannot be cut by any known method

Researchers from Durham University (UK) and Fraunhofer Institute (Germany) have developed a material whose sole mission is to oppose any attempts to cut. This does not mean outrageous strength or even invincibility – on the contrary, named “Proteus”, the new material may well be destroyed. But cutting or drilling with a mechanical device completely useless.

Proteus consists of an aluminum base, in which the raisins into the dough rolls evenly inserted numerous ceramic spheres. They are fixed in place and not so strong – on the contrary, the external ceramic layer actively crumbles under the load, turning into grains of sand. Because of this, in place of the deformation forms a viscous mess of ceramics, dust and metal particles that fills the gap.

It is very similar to how a bullet gets stuck in the bag with the sand, the farther it moves, the more grains of sand begin to communicate with her, slowing the movement. If instead of a metal drill to take the cutting tool provides, round and movable ceramic particles will rotate under the action of the jet and to reflect it in different directions that will eventually make her as useless. Can be left on the surface of the aluminum body Proteus as many cuts, but to cut it entirely fail.

As noted by the co-designer Stefan Chinesische, trying to cut Proteus is akin to attempts to break a jar of jelly diamonds. The developers plan to use new to create light armor and protective gear against bladed weapons and other similar threats. Also it is possible to make the cables anti-theft alarm for bikes which are unlikely to bite even the bolt cutters.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
