Tetraneutron discovered

14.02.2016

Scientists from the Institute of Physical and Chemical Research of Japan reported the discovery of a tetraneutron candidate.

A tetraneutron is a resonant particle consisting of four neutrons. The energy of an open particle is approximately 0,83 megaelectronvolts.

Scientists have not been able to directly observe the particle because its energy is extremely low. However, with the help of conservation laws, physics showed the birth of a tetraneutron during experiments. In total, scientists registered four events associated with new resonant states.

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, ... >>

Efficient installation for energy storage in compressed air 04.10.2022

Compressed air energy storage systems are nothing new. The problem was their relatively low energy efficiency, which Chinese scientists successfully solved. Based on the development in Hebei Province, the world's most advanced 100 MW air-compression energy storage system has been created, tested and will be put into commercial operation by the end of the year.

The world's first CAES (compressed air energy storage system) project on a utility scale was implemented in Germany in 1978. The plant is still in operation today, providing an output power of 290 MW. CAES equipment pumps atmospheric air into voids in the ground, compressing the air to a pressure of about 140 atmospheres. The efficiency of the German installation is 40%, which is significantly lower than pumped storage power plants with energy reserves in the process of pumping water masses to a great height (efficiency up to 75%) and battery storage, the efficiency of which reaches 90%, but is realized in the course of the most serious financial injections.

In the process of compressing air, a CAES unit releases a lot of heat energy. The German project does not use this heat, and when releasing compressed air, it uses fossil fuel combustion to heat it, which in combination greatly reduces the efficiency of the solution (additional heating greatly increases the pressure of the outgoing air flow and enhances the work it does - the rotation of generator turbines).

Chinese engineers have learned how to capture and efficiently store the heat generated in the process of air compression and then reuse it to heat the air supplied to the turbines. According to the test results, the heat storage efficiency is maintained at 98,95% after eight hours and 98,73% after 16 hours, which is the highest among existing CAES heat storage devices.

In parallel, other projects are being implemented in China on systems for collecting energy from renewable and therefore unstable energy sources, such as the sun and wind. For example, a 100 MW storage system based on vanadium flow batteries is being built in Dalian, and energy storage projects have been launched in Inner Mongolia, Ningxia and other regions, both in conventional lithium batteries and in more exotic options, such as using flywheels. China is striving to become a leader in energy storage and is testing all possible options to achieve its goals.
