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, ... >>

Flying a little lower, the plane harms the environment less 07.02.2024

A study of six million airline flights found that small changes in altitude during flight can significantly reduce harmful emissions from aircraft engines that contribute to global warming.

A temporary change in altitude would allow planes to avoid areas of high humidity and pressure, which contribute to the formation of aircraft trails - water vapor and soot, which cause significant environmental damage, no less than carbon dioxide emissions.

Scientists from the Technical University of Delft estimate that if 61 percent of the planes examined lowered their altitude by 326 meters, and 39 percent, on the contrary, rose to 305 meters, then emissions of water vapor and soot would be significantly reduced. These changes do not require significant additional fuel consumption and do not increase safety risks, but only allow aircraft to avoid areas with high humidity and temperatures less than 40 degrees Celsius, which contribute to the formation of wakes.

Scientists believe that more than half of the flights could allow altitude changes within 609 meters, which would be enough to reduce the formation of wakes behind aircraft. While these measures will not reduce carbon dioxide emissions from fuel consumption, they will still help reduce aviation's global warming contribution, which accounts for five percent of total human-caused activity.

Changing the altitude of aircraft can be an effective strategy to reduce their environmental impact, promoting cleaner skies and less contribution to global warming.
