Toshiba launches new generation of 4K TVs

05.07.2013

Toshiba Corporation officially introduced the second generation of Ultra HD (4K) LCD TVs, which included models with a screen diagonal of 58, 65 and 84 inches. All of the new devices are equipped with 6-core processors to convert sub-4K content to 4K with "quality close to that of original 4K content," the company said.

In addition, all devices have Ethernet and Wi-Fi support and offer users an expert mode for adjusting image parameters.

The 58L9300U, 65L9300U, and 84L9300U will be available in the US in August 2013 for $4999, $6999, and $16999, respectively.

The Ultra HD format offers four times the resolution of Full HD - 3840 x 2160 versus 1920 x 1080 pixels. Notably, Toshiba was the first company to introduce such a TV to the consumer market in October 2011.

Subsequently, similar devices were released by other manufacturers. So, for example, since April 2013, Sony Corporation has been selling the XBR-55X900A and XBR-65X900A models with a diagonal of 55 and 65 inches in the US for $5 and $7, respectively.

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, ... >>

Iron mining on Mars 01.10.2022

Australian researchers at Swinburne University of Technology have developed a process to produce iron on Mars. They propose using concentrated sunlight as an energy source, and extracting iron from regolith using carbothermal reduction.

Experiments on the Perseverance rover have shown the possibility of extracting oxygen on the Red Planet using the electrolysis of carbon dioxide (CO2). During this process, a large amount of carbon monoxide (CO) is released as a by-product. The researchers propose to combine an oxygen plant with iron production to use by-products.

In their calculations, the scientists showed that the hot gas produced by the electrolysis of carbon dioxide would be rich in CO (91%). It can be used to preheat regolith. In addition, by condensing the monoxide, pure carbon can be obtained.

The researchers analyzed the composition of the Martian regolith (soil) and found that by adding 10% carbon to it at a temperature of 1120 ° C and a pressure of 7 mbar (atmospheric pressure on Mars), liquid iron can be obtained with a conversion of 99,9%. In this case, the alloy will contain a small amount of impurities of carbon, silicon, phosphorus and chromium.

Experts believe that the resulting material can be used for the independent production of various machines and devices for a colony on Mars. The technology is based solely on local materials and does not require the delivery of goods from the Earth.
