Scientists of the world community have done a serious job and learned how to create lattices of electrons with sound, the media reported with reference to profile publications. It is reported that the research results will help in the process of modeling complex quantum systems.
According to experts, acoustic waves can act as a tool for creating lattices of electrons of a stable type, the same process can be used for polaritons and their further transformation. The frequency of the oscillations is able to influence the result obtained, as a result of which the charged particles are set in motion.
The researchers explained that these grids can serve as a means for gathering information and its source, which tells about the interaction of particles inside the device. This work has opened the way to the creation of the most complex quantum systems, what now experts will do.

The opening of undergraduate students from the Massachusetts Institute of Technology can make concrete stronger, reduce carbon dioxide emissions from its production, and at the same time find useful applications for various plastics in landfills. +
"Every year, a huge amount of plastic comes into the garbage vaults, with which no one knows what to do," explains Michael Short, associate professor of the university department. "We invented a method of how to make something useful out of this garbage, and economically beneficial."
Plastic and tried to add to the concrete, however, each time it turned out that it degrades the strength characteristics of concrete. This time scientists have subjected plastic gamma-irradiation, which changed its crystal structure.
For this purpose, they took the most common thermoplastic polymer polyethylene terephthalate (PET), the material from which plastic bottles are made. Chopping it, the scientists sent the material to the irradiator, where they exposed it to cobalt-60. This element emits gamma rays similar to those used for sterilizing food products and medical instruments.
The addition of recycled plastic has made the concrete 20% stronger
After that, the irradiated plastic was ground to the powder state, and mixed with a concrete mixture in which coal ash (a by-product of coal combustion) and silicon dioxide (a by-product of silicon production) were present.
During the compression tests, it turned out that the concrete into which the treated polymer was added became 20% stronger than the conventional one.
After studying the new material with X-ray diffraction and inverse scattering electron microscopy, the scientists found that high-dose irradiated plastics, due to their unusual crystal structure, somehow blocks (clogs) the pores of the concrete, thereby giving it increased strength.
As a result, with the help of this technology it is possible to create very strong concrete, while at its production will go to 35% less cement. This will not only reduce the cost of production of this most used material in the world, but also reduce harmful emissions from its factory production. And, of course, with this, mankind will finally be able to find a useful application of spent plastics.

Scientists from the European Organization for Nuclear Research explained why our universe should not exist.
The results of research by CERN specialists were published in the journal Nature. A group of physicists conducted a series of experiments and found out that the existence of our universe is contrary to all the laws of physics. According to scientists, the universe had to self-destruct at the very beginning of its creation. This was due to the same amount of matter and antimatter.
Why did antimatter not serve the elimination of the universe - a mystery, the answer to which many scientists are trying to find. By the standard model of the creation of the universe, after the Big Bang, the formation of matter and antimatter occurred. According to the latest data, these materials are considered to be completely identical and differ only in the sign of the charge. But in that case, they had to self-destruct, because this did not happen, scientists are trying to find some more differences between matter and antimatter.
Christian Smorra, one of the authors of the study, explained that the difference between matter and antimatter should be manifested in some aspect, but so far scientists have no guesswork. Therefore, scientists intend to study antiprotons in more detail in order to get to the bottom of the truth.

Why do we need a TV box, if most TVs are already "smart"? Prefixes on Android offer more services and choice of applications, install or delete which is much easier. Gadgets with advanced hardware "stuffing" work smartly: web surfing, games, social networks, music and photos, movies in 3D and 4K resolution, video calls - all this is in compact devices for a relatively low price. In this collection - prefixes on Android, expanding the capabilities of the TV.
TV boxes with a 5 GHz Wi-Fi band for seamless connection
All the set-top boxes in the first part of our collection can be connected to a 5 GHz wireless network. Why is it important? The fact is that most home devices are connected to routers at a frequency of 2.4 GHz. This range is heavily loaded, especially in apartment buildings. Due to interference, the data transfer rate is reduced. "Heavy" multimedia content is better to transmit in a freer five-gigahertz range.
The updated TV box Beelink GT1 Ultimate received more memory - 3 GB of RAM (DDR4), so you can run games heavier. The console is controlled via a remote control or a portable wireless keyboard with a touchpad that is shipped separately. The box supports dual-band Wi-Fi, Bluetooth 4.0, and allows you to play your favorite movies and TV shows in 4K resolution at 60 frames per second. There is a QODI media player, a KODI clone, with which it's easier to manage content. The device is based on the eight-core processor Amlogic S912 and Android 6.0.
In July of this year, the NEXBOX A95X TV box was slightly updated: the Amlogic S905 chip is replaced by the quad-core Amlogic S905X, and Android 5.0 came to replace the Android 5.1. The prefix is available in two versions: with 1 or 2 GB of RAM and 8/16 GB ROM "on board" - this is enough for downloading applications, running games and surfing the Internet. The package includes a convenient, customizable remote control. Its programmable keys can be assigned to the buttons of the home TV remote and one-touch to send to sleep mode instead of turning it off. Separately, the console offers a gamepad or a portable keyboard, with which it will be comfortable to play or correspond. Bottom of the NEXBOX A95X there are ventilation holes, and on the side faces - a standard set of connectors: AV output, two USB 2.0 ports, HDMI-connector, LAN-port, microSD-slot and S / PDIF optical output.
Mini M8S Pro is one of the most affordable boxes on the eight-core Amlogic S912 with the graphics core Mali-T820 MP3. The gadget has received the plastic case in dimensions 110 x 110 x 17 mm - such a gadget does not take much space, and even in the eyes will not rush particularly. The top and bottom panels of the Mini M8S Pro have a matte surface, the side faces are glossy, translucent. Due to this, the remote control will "reach" the Mini M8S Pro from either side. The gadget is equipped with 2 GB of RAM and 32 GB of internal memory. Control is carried out using the keyboard, mouse or remote control. Mini M8S Pro turns TV into a real entertainment center, which is enough to connect a smartphone, gamepad, headphones or any headset. There is boxing on Android 6.0.
Turn the TV into an entertainment center with the Mecool M8S Pro. Duo eight-core processor Amlogic S912 and graphics chip Mali-T820 MP3 "pull" movies in 3D and serials in 4K-resolution at a frequency of 60 frames per second, games, applications and online video. For smart work, the console has 2/3 GB of RAM and 16/32 GB of ROM. The owner of Mecool M8S Pro can try and office applications: for these purposes, a wireless keyboard is offered separately. The TV box supports DLNA, Miracast and AirPlay for streaming multimedia. Deliver a gadget with Android 7.1.
Inside the H96 Pro Plus, the same pair is installed - an 8-core Amlogic S912 processor and a Mali-T820 MP3 graphics chip. They will cope with Internet surfing, playback of video content in 2K and 4K resolution at a frequency of 60 frames per second in HDR10 and Dolby Vision formats. For added convenience, a free KODI media player is available: it's easier and more convenient to manage video files, music and photos. The box is available in two versions: with 2 GB and 3 GB of RAM. The amount of internal storage is 16 GB. H96 Pro Plus runs on Android 7.1.
The Xiaomi Mi TV Box 3S with a quad-core Amalogic S905X and a stock Android TV 6.0 joined the compilation. Against the background of other participants, the memory capacity of this model is rather modest - 2 GB of RAM and 8 GB of ROM, but enough to install a small number of applications and games. The box reproduces YouTube TV movies and movies in 4K and 2K resolution at 60 frames per second and HDR support. There is a gadget with Wi-Fi frequencies of 2.4 GHz and 5 GHz, so there will be no problems with network configuration. The console supports Bluetooth 4.1 and is equipped with a USB 2.0 port - there is the possibility of connecting headphones, a wireless keyboard, a gamepad and another headset. Dimensions of the device are
