Atoms promise as proton conducting membranes, for each of the thinner mineral green technologies.

Experiments by researchers at the University of Manchester have found that the atom is a type of common mineral found in each form of thin mic - soil, and is an excellent proton conductor, and this amazing result results in fuel cells and other hydrogen-related technologies, As such, it is important to use 2-D materials in applications.

Researchers have conducted many experiments before, with Manchester researchers led by Professor Andre Geim and Dr. Marcelo Lozada-Hidalgo finding that, like graphene, a one-atom thick material is highly permeable to the nuclei of protons, hydrogen atoms. However, researchers also found that there are many other 2-D substances, like molybdenum sulfide (MoS2), which had only three atoms thick, and are completely impermeable to protons.The results of the experiment by the same researchers suggested that any one-atom thick crystal can be permeable to protons.

Researchers, writing in Nature Nanotechnology, have shown that protons can allow very easily, through multiple layered micas, and are about 10 times thicker than graphene, because micas and graphite  Like, crystal layers stacked on top of each other, and can be moved down to one layer, the team of researchers separated one of these layers, and this  Or, that was 100 times more permeable to protons than Graphene proton.

The team of researchers said that at first, this result seemed impossible to come up with, because micas are too thick for protons, and this monolayers are much thicker than MoS2, and would be completely impermeable to protons. However, the researchers pierced the tubular channels in their experiment, and it was found that the mic can be thought of as a crystal slab, because the channels are not empty, but are filled with hydroxyl groups, because it  In water the protons of a one-dimensional chain operate, and these protons jump along these chains, and this makes the material an excellent proton conductor Switch to change. 

During the project, Lucas Mogg and a Ph.D. he said.We have found that the proton conductivity in the atom-thin mic is 10 to 100 times greater than that of graphene, and this is encouraging, as it was previously considered graphene to be a promising protecting material.Researchers' results show that mikes can be more promising because they are the least abundant and inexpensive.

Professor Andre Geim believes that this can also result in many other 2-D materials being turned into proton conductors. Professor Andre Geim states that our strategy is not limited to protons or micas only.And it is similar to mic with many 2-D crystal atomic-scale channels.Professor Andre Geim says that we can, that will bring many unexpected events, and fresh new applications in the field of protons and ionic conductors.

Researchers have also found in their experiment, mikes are highly conductive in temperature range, and are notorious for related technologies.Dr,Marcello Lozada-Hidalgo states that there is a shortage of proton-carrying materials, and that they can work reliably between 100 ° C and 500 ° C.  However, it is the sweet spot temperature range for optimal operation of many fuel cells and for, and each of the hydrogen technologies, and atmoli-thick mikes in this temperature range work correctly, and they draw attention from this point of view.

And in addition to all this, the researchers believe that they are now working on making a mica prototype membrane, and this is a large enough test for industrial conditions, the area of ​​two-dimensional ionic conductors, and the properties of each crystal  Promises more, and can be converted into other ionic and proton conductors.

The Esa / Nasa Hubble Space Telescope captured the image of cluster 47 Tucanae.

The Nasa/Esa Habble telescope has captured an image of a group of stars, spherical in shape, spanning a large area, this group of stars has billions of stars, these stars have their own color, which is much about them  It says.  In the image we can see, around 35,000 stars are visible near the center of the cluster 47 Tucanae , the stars are tightly packed near the core (top left) of the cluster, and propagate farther away from the core.

In the cluster image of stars, how stars are shown in natural colors, scientists have told about their composition and age through the color of stars, as the star which appears red, the stars end of their life. Is near, bright red signifies giants, while more common yellow stars indicate that these stars are still young, whose age is similar to our sun.

Cluster 47 Tucanae image taken by Hubble's Wide Field and Planetary Camera 2, this image was taken in 1999.

According to Nasa's report the rules protecting other planets from pollution can be very strict

Some scientists believe that the moon will have an interesting mission to seek life, with scientists also considering it as a potentially interesting site to investigate the origin of life on the Moon. But some scientists say that most of the moon is not astrologically interesting. Some places on the moon, Mars and other planets are safe, while some places are unprotected.  Some policies may be too strict to protect the Moon, Mars and other places.

What was the conclusion of NASA's 12-expert panel To review voluntary international guidelines, to keep space missions polluting other worlds with earthly life. These guidelines are recommendations of the international scientific organization COSPAR, which revised policies for spacefaring countries for decades.  Nasa will send a sample-collection mission to Mars next year, the same other space agency also lunar  Interpretation of preparing the trip, as the scientists, there is an urgent need to update safety guidelines of the planets.  A…

How did life begin on Earth? Is it possible by a violent collision on the moon.

The moon, which has many stories to make, did the violent, and cosmic collision during the making of the moon make life possible on earth? This is a big question, but a new study shows that this is true. Science has given many theories about life on earth, but there is always a question in our mind that how life came to be born on earth.Given by science, has many theories, and tries to explain to us how to find elements for life on our planet: such as carbon and nitrogen elements.
Scientists have previously believed that meteorites have brought life-giving elements to Earth, bacteria with meteorites coming from space for example, and the energy of explosions caused by the continuous fall of meteorites from organic matter.Synthesis of. And the isotopic signatures of these elements on Earth coincide with those objects, but what? The ratio of carbon to nitrogen is not very accurate.If we think of transporting the elements that are important for life on Earth due to meteorites, then each p…
