Breakthrough enables mechanical waves to release storage without energy.


Friends, as we know, that there are waves of light and sound, based on their energy and signal transport, that are fundamental to some of the most basic technologies, because from cell phones to engines, scientists have, so far,One such method is derived, or a method has been developed, which allows them to store a wave for an indefinite period of time, and it then directs it to a desired location.And such development would lead to energy harvesting if the ability to manipulate waves would be greatly facilitated for desired uses, including quantum computing, structural-integrity monitoring, information storage, and more experimentation. X in Science Advances  In a newly published paper, a group of researchers led by Andrea Aloe advanced science research center (ASRC) at The Graduate Center, QNY  Georgia Tech, by the founder director of the Photonics Initiative, and Massimo Goozin, professor of aeronautics engineering, Georgia Tech, has shown experimentally that it is possible to capture, and store, a wave intact, and then store it in a specific  Can move towards the location.

Experimentation thus proves that wave propagation is an unconventional form of excitation, and seeks new opportunities to gain control over scattering, according to Alo, when carefully observing the time dependence of the excitation, and the wave  It is possible to do the trick to efficiently store it in a cavity, and then leave it out of the mode towards a desired direction.  Scientists had to devise a way to change the basic between waves and materials.When a light or sound wave hits an obstacle, or collides, it is partially absorbed or reflected and scattered.The same absorption process very soon insists on converting the wave into heat or other forms of energy.Even materials that cannot absorb waves, but only reflect and disperse them, the researchers aimed to find a way to convert the wave into other forms of energy and mimic the absorption process.Theoretically introduced by the ASRC group two years ago, and the concept is known as coherent virtual absorption.Researchers argued their theory, and they needed to tailor the evolution at the time of the waves, because when they came into contact with non-elimination material, they would not be reflected, scattered, or transmitted. And it will be efficiently trapped inside, and the stored wave can then be released on dimand During their experiment, the researchers propagated a carbon steel waveguide bar during the experiment and two mechanical waves traveling in opposite directions, along with a cavity, and carefully controlled the time variation of each wave to ensure Was done, that the cavity will retain all impulse energy. When stopping the excitation or isolating one of the waves, they were able to control the release of stored energy and shift it to a desired direction on demand.

When researchers carried out the use of elastic waves traveling in solid materials, and the proof-of-concept experiment, it was found that these findings also apply to radio-waves and light, and efficient energy harvesting,Wireless power transfer, low-energy photonics, and generally offer exciting possibilities for enhanced.

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…
