Data can be stored in the dust

11.11.2018

Scientists from the University of Ghent have discovered a technology for recording small amounts of information, such as a bit of text or a QR code, onto grains of powder.

Specialists have developed a chemical process by which they were able to translate information into a chemical signature on a macromolecule with a certain sequence, that is, a molecule with a certain chain length and known subgroups. The researchers then developed two computer algorithms. One fully automates the process of converting information into a chemical form and vice versa. The other is responsible for making this process happen quickly. It's all about the amide-urethane oligomers on which information is recorded, and the operation of the algorithms is based on the techniques of tandem mass spectrometry.

The programs are called Chemcoder (it encodes and decodes information) and Chemreader (it automates the process of chemical writing and reading).

As a result of all their efforts, the scientists were able to make a powder that contained links to websites and applications.

This is not the first unusual way to store information - researchers have already found ways to store data on DNA or diamonds, but so far the problem is that they are still far from industrial scale and penetration into our daily lives. Although the prospects for the use of data dust are extremely wide, it is true, rather than in our homes, but for military or intelligence purposes.

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, ... >>
