Created the most powerful magnet in the world

22.12.2017

A powerful superconducting magnet presented by American developers generates a field with a magnetic induction of 32 Tesla, which is 3 times more than the previous record and 3 times "stronger" than a souvenir fridge magnet. The novelty was developed by engineers from the National High Magnetic Field Laboratory together with SuperPower Inc.

The design of the 32 T magnet is a hybrid of low and high temperature superconductors. Along the way, the developers managed to create a number of new methods for isolating, amplifying and supplying energy to the system. A magnetic field of 32 T will help scientists in studying the interaction of electrons with each other and their atomic environment. A heavy-duty magnet is also necessary for the creation of scientific instruments - X-rays and neutron scatterers. The novelty will be available for use by scientists from all over the world in their scientific research, which will help in new discoveries in various fields of knowledge, including physics, chemistry and biology.

The discovery of high-temperature superconductors by Karl Müller and Georg Bednorz in 32 helped scientists create a super-powerful 1986 T magnet. The use of superconductors of this type has become available at relatively high temperatures, at which the effect of superconductivity is triggered. Scientists who made breakthroughs in the science of superconductors were awarded the Nobel Prize in 1987.

A more powerful magnet had already been created earlier, the team from the MagLab laboratory managed to obtain a device based on conventional conductors with a power of 41.4 T, but for its operation it required too much energy (32 megawatts of DC power), which made it impractical.

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, ... >>

Smart Light Bulb Connected Cree LED Bulb 23.01.2015

Cree has unveiled its new Connected Cree LED Bulb. This is the first LED lamp in the range of the manufacturer, which is endowed with intelligent functions and is compatible with most smart platforms.

The novelty replaces a conventional 60-watt incandescent lamp, while consuming only 11,5 watts, and is compatible with Wink hubs, ZigBee, and the Apple HomeKit platform. The user gets the ability to remotely control the Connected Cree LED Bulb using a smartphone running iOS or Android and a special application. For example, you can set the lamp to turn on and off according to a schedule, or remotely turn on the lamp when you are away for a long time to create the illusion that the owners are in the house for security purposes.

The Connected Cree LED Bulb emits a soft omnidirectional light thanks to its 4Flow Filament Design. The lamp is made in a compact and durable case. The brightness of the lamp is 815 lumens at a color temperature of 2700K. The life cycle of the device is 25 thousand hours.
