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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. 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, ... >>

Acoustic levitator for food transfer 13.10.2017

The SCHI Lab at the University of Sussex has developed a prototype acoustic levitator designed to hold and transport droplets and pieces of food through the air. The authors will make a presentation at the ACM ISS conference, which will be held next week in Brighton (UK).

Sound is an acoustic wave moving through space. Acoustic levitation is based on the fact that emitters directed at each other create a standing wave. Moreover, if an object placed in a standing wave is two or more times smaller than the acoustic wavelength, it will hang in one of these areas.

Despite the fact that acoustic levitators have existed for a long time, such devices are rarely used to solve any practical problems. Now, British engineers have proposed using acoustic levitation for non-contact transportation of food.

Their prototype, called TastyFloats, can carry small drops and pieces of food, including several different ingredients at the same time. It is assumed that the levitator will move the treat to the person's mouth, after which he can eat food directly from the air.

To demonstrate the performance of their installation, the authors placed several drinks and dishes in the acoustic field, among which, for example, were wine, milk, coffee with milk (two separate drops) and even a microburger consisting of four different pieces (2 pieces of bread, meat and salad ).

The researchers also suggested that food delivered with TastyFloats might taste different, for which they invited 11 volunteers to try drops with three of the five basic tastes: umami, sweet and bitter. Subjects received drops of 5, 10, and 20 microliters per tongue via pipette or TastyFloats and were asked to identify the taste and describe its intensity. It turned out that the delivery of food using an acoustic levitator affects the taste - the volunteers said that sweet was felt more pronounced, while bitter, on the contrary, was felt weak and indistinguishable with this method of delivery.

The developers offer several options for using TastyFloats, among which there are both realistic (delivering desserts or, on the contrary, bitter food) to the mouth, and fantastic projects - for example, one of the proposals describes an "edible cinema" (Edible Cinema), in which built-in similar food dispensers.
