Created a unique cold matter

10.09.2022

A team of scientists at Kyoto University has created the coldest matter in the universe. It is three billion times colder than interstellar space.

For the experiment, scientists used fermions, which physicists call any particles in the composition of matter. They cooled the ytterbium atoms to about a billionth of a degree above absolute zero, the hypothetical temperature at which atomic motion would cease.

Lasers were used for cooling. The conducted experiment simulates the model of quantum physics, first proposed in 1963 by theoretical physicist John Hubbard. It allows atoms to exhibit such unusual quantum properties as superconductivity.

It is noted that interstellar space is never so cold, as it is evenly filled with cosmic microwave background radiation. According to scientists, the created matter is even colder than the Boomerang Nebula, which is the coldest known region of space. The temperature is only one degree above absolute zero.

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 ... >>

Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Construction of houses from grass blocks 22.08.2023

North Carolina-based construction company DR Horton, one of the largest real estate developers in the US, has begun a revolutionary use of pressed perennial grass in the home building process.

The essence of the innovative idea is to create panels obtained by pressing large volumes of fast-growing plants. These panels have the potential to replace traditional building materials used for walls and ceilings.

The pilot project began life as a series of homes in North Carolina, where DR Horton partner Plantd is implementing this innovative approach. Grass panels are becoming an alternative to conventional oriented strand board (OSB) and plywood.

Plantd undertakes not only the cultivation and harvesting of plant materials, but also the creation of production machines capable of producing up to one panel per minute. The company is currently working on an all-electric plant that will include 50 production lines and will be up and running within the next few years.

According to the company, its panels can replace up to 16-17 trees needed to build one house, which, in turn, requires about 175 panels for walls and roof.

What's more, Plantd actively researches perennial biomass in its lab and claims that its current panels offer improved moisture resistance and durability over comparable products available on the market.

Now, as part of its pilot project in North Carolina, DR Horton is completing a "trial" home. Following the successful installation of this home, the company intends to purchase 250 panels for use in more than a thousand family homes, demonstrating the potential of this unique technology.
