Electric price tag

16.06.2006

British scientists are developing liquid crystal cells that will greatly facilitate the life of the owners of supermarket chains.

Dr. Tim Spencer from the University of Sheffield says: “Imagine that you are the owner of a thousand stores and you need to change the price of jars of green peas in all stores at the same time. You will need to make a lot of new labels, and besides, no one is safe from error. it's easier if the same thing can be done with the push of a couple of buttons on a single computer.This is where the electrical labels we design come in handy."

The new labels are liquid crystal displays, and they need electricity only when the picture changes. The rest of the time the display shows it without power consumption. The store owner almost does not bear the cost of maintaining electric labels and at the same time gets rid of a mountain of small pieces of paper. Yes, and it is more convenient for buyers - the true information is always reflected on the price tag.

The idea of electric labels was supported by such a British trade giant as the Tesco company, which owns supermarkets around the world: the first successful experiment took place in one of the chain's stores located in Leicester. "Labels are just the beginning. We want to reduce the electrical voltage required to write information on displays, and if successful, they can be used in smart cards and cell phones.

The energy consumption for creating images will be so small that the battery charge will be enough for a much longer time, "- says Dr. Spencer.

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, ... >>

Graphene speeds up optical switches by 100 times 05.08.2013

Scientists from the Universities of Bath and Exeter in the UK have come up with a way to increase the speed of optical switches used in telecommunications equipment by 100 times. The corresponding scientific article was published in the journal Physical Review Letters.

"Every day, huge amounts of information pass through optical fibers, photodetectors and lasers. Signals sent in the infrared wavelengths pass through optical switches that convert them into a sequence of light pulses," the scientists say in the work.

The essence of the invention is the use of graphene in the design of an optical switch instead of a conventional semiconductor. Graphene is a lattice of carbon atoms one layer thick.

"Thanks to its high strength, flexibility and conductivity, lightness and low price, graphene is one of the most promising materials. And now we see that it allows you to reach new frontiers in the telecommunications market," the scientists comment.

“The more we learn about graphene, the more amazing new properties we discover in it,” says Simon Bending, co-leader of the Graphene Research Center at the University of Bath. “During our research, we saw that this material has unique optical features that open up new possibilities.

Graphene has previously been proposed for use in telecommunications equipment. In March of this year, scientists from the Georgia Institute of Technology, USA, developed a graphene antenna that allowed data to be transmitted at a speed of 1 Tbps.

Another example is the joint work of Nobel laureates Andrey Geim and Konstantin Novoselov, who two years ago developed a method to increase data transmission speed over fiber optic networks by a factor of 20. Their work was also based on graphene discovered by them earlier.
