Kinescope on Chernobyl

04.03.2000

Every year, German viewers throw into the landfill about half a million used kinescopes weighing from 10 to 30 kilograms. Burying them is a big problem. Firstly, the phosphor that covers the screen from the inside contains cadmium and is therefore poisonous. Secondly, the cone of the kinescope is made of lead glass, which is also unsafe for burial (this glass absorbs X-rays that occur when the TV is in operation). And it is also difficult to melt it into new kinescopes, because the screen itself is made of another, barium-strontium glass, which also absorbs radiation. For secondary use, these varieties would have to be separated.

The Munich company "Stratecon" proposes to use German kinescopes for shielding the Chernobyl sarcophagus. The idea is to build something like a rack of steel corners around the sarcophagus, on which to place old kinescopes in two layers, alternately - neck or screen first. You can also fill them with some material that absorbs radiation. Then this structure is poured with concrete.

This idea has already been patented, and both in Germany and Ukraine, the first experiments to test it are underway. It is estimated that several hundred thousand old kinescopes will be needed for its implementation.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Adapter SilverStone ECM23 17.09.2018

SilverStone has announced an accessory with the designation ECM23 - an adapter that allows you to use M.2 solid state drives (SSD) in computers without the appropriate connector.

ECM23 is a kind of cartridge inside which you can install an M.2 PCIe module. Work with products of standards 2230, 2242, 2260 and 2280 is supported - 30, 42, 60 and 80 mm long respectively.

The adapter is designed for installation in a PCIe x16 slot. In this case, the PCIe x4 interface is actually involved. An LED indicator is provided to indicate data read/write operations.

The novelty has dimensions of 105 x 11 x 44 mm and weighs 52 grams. The adapter features an aluminum heatsink and thermal pad to dissipate heat from the installed SSD.
