smallest storage device

29.11.2020

Engineers from the US and UK have created the world's smallest atomic data storage device. Its performance is one hundred times higher than that of modern flash drives, according to the press service of the University of Texas at Austin (USA).

Scientists called the new device "atomristor" (combining the words "atom" and "memristor"). They used molybdenum disulfide (MoS2) as the main nanomaterial. Previously, researchers have created a similar device, reducing its thickness to one atomic layer. This time they went even further and reduced not only the thickness but also the cross-sectional area of the device. The resulting version of the memristor promises a performance of about 25 terabits per square centimeter.

"When another metal atom enters and fills this nanoscale hole, it transfers some of its conductivity to the material, and this leads to a change or memory effect," said study leader Deji Akinwande, professor in the Department of Electrical and Computer Engineering at the University of Texas at Austin. "The holy grail of science is to bring the scale down to where a single atom controls the memory function, and that's what we've achieved in the new study."

Smaller processors will enable smaller computers and phones. Reducing the size of chips also reduces their power consumption and increases their capacity, so devices will run faster and use less power to operate.

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, ... >>

Approved a single standard chargers for all gadgets 02.12.2022

European Union environment ministers have finally approved the introduction of a common standard for chargers for small electronic gadgets by 2024.

USB type-C will become mandatory for a number of devices such as mobile phones, tablets and e-readers, digital cameras and game consoles, headphones and speakers, wireless mice and keyboards and portable navigation systems.

The rules will apply 24 months after they go into effect, likely in the fall of 2024.

For laptops, there is a longer transition period of 40 months, which means that a common single device for laptops will appear in early 2026.

"Having a charger that fits multiple devices will save money and time and help us reduce e-waste," said Czech Industry Minister Józef Sikella.
