artificial sun

08.08.2019

American scientists from the University of Wisconsin were able to create a mini-copy of the Sun in the laboratory in order to better learn about the structure of a real star. The project was named Big Red Ball.

The project was the first in which scientists managed to create reactions that mimic the Sun's magnetic field. It is impossible to simulate all processes completely in the laboratory. This time, as noted, the team managed to implement the movement of solar plasma.

With the help of research, physicists intend to find out why and how the solar wind occurs. It is a stream of charged particles of plasma and gas, which flows at extremely high speeds from the surface of a star.

The model is a hollow three-meter sphere filled with helium plasma. To create a magnetic field, scientists placed magnets in the center of the sphere. As a result, when the physicists turned on the mini-copy, the particles began to rotate around the center due to the force of the inner core.

However, at a speed of 35,5 thousand km / h, the plasma escaped outside the sphere, showing how the solar wind works. The project helped scientists figure out how he manages to overcome the attraction of a star.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Radio modem based on CC1310 01.03.2016

Texas Instruments has released new software for the CC1310 that turns the chip into a complete radio modem controlled by AT commands. The CC1310 system on a chip consists of a Cortex-M3 microcontroller and a Sub1GHz radio, which allows you to create complete devices with wireless data transmission on a chip. However, in many cases it is required to add a radio channel to an already existing system with its own microcontroller. The new firmware (firmware) allows to solve this problem in a short time and with a minimum of engineering effort.

The rfEasyLinkNp software turns the CC1310 into a network processor, ie. into a microchip that completely takes care of all the tasks associated with wireless data transmission. At the same time, the system designer does not need to dive into the internal structure of the CC1310, packet formation features, modulation parameters, etc. This approach is often used by radio module manufacturers.

To add a wireless protocol, just read the description of a dozen AT commands. For example, to receive data, the main system controller sends the AT+RX command to the network processor , which in turn outputs the received data to the UART.

The network processor can do address broadcasting and has message filtering when receiving, which allows you to organize a "Star" network of hundreds and even thousands of devices in the 868 MHz band.

The unique feature of rfEasyLinkNp software is its completely open source code. This allows the advanced developer to add new AT commands or modify existing ones. Additionally, the network processor contains commands to generate a continuous carrier and send packets for transmission error testing, which will be extremely useful when testing devices in the production process.
