PHILIPS introduced a mirror-TV

17.03.2004

The Dutch company Philips has announced a curious novelty - "mirror TV", which is called - Mirror TV.

This device is a built-in mirror. LCD panel that works as a TV. However, if you turn it off, the panel will look like a normal mirror. In addition to the functions of a TV, Mirror TV may well perform the functions of a monitor, for which the device has the appropriate connectors. Mirror TV was originally developed for use in hotels, but now Philips is positioning this device as a home interior item.

Prices for Mirror TV are still unknown, as is the exact date of the start of deliveries. However, it is expected that the first lots containing LCD-matrices with a diagonal of 17, 23 and 30 inches will go on sale next year.

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, ... >>

Mushrooms found to extract gold from the soil 28.05.2019

Today, Australia ranks second in the world in gold mining. However, according to experts' forecasts, the volume of the precious metal mined will decrease in the near future if researchers do not find new deposits.

An interesting approach was proposed by scientists from the State Association of Scientific and Applied Research of Australia (CSIRO). They suggest using ... mushrooms to search for precious metal deposits.

In the course of the new work, experts found that filamentous fungi called Fusarium oxysporum are literally gold-bearing. Scientists have found that if you look at these fluffy mushrooms under a scanning electron microscope, you can see that their threads are "encrusted" with gold nanoparticles.

For research, the team collected colonies of fungi that grow on soils near the Boddington mine in western Australia, where gold and copper are mined.

Geochemical and other analyzes have shown that Fusarium sharpspore collects gold through chemical reactions that involve underground minerals. By producing superoxides, the fungus oxidizes the collected gold and then produces another chemical that causes the dissolved gold to solidify around the filaments.

It is not yet known exactly what role the gold "extracted" by it plays in the life of the fungus. However, experiments have shown that Fusarium sharpspore grows and spreads faster in an environment where this noble metal is present.

According to the team, this discovery could play a key role in the search for new gold deposits.

In the future, experts intend to find out whether the extensive colonies of these fungi are a sign of the presence of gold under the earth's surface.

Fusarium ostrosporovy, by the way, is widespread. Therefore, if the assumption of scientists is confirmed, a new way to search for the precious metal using "mushroom beacons" is likely to help increase gold mining around the world.
