Zakharova commented on the US reaction to the ICC charges against the Israeli authorities Posting in CHAT: Russia On May 20, ICC prosecutor Karim Assad Ahmad Khan called for the issuance of arrest warrants for the Israeli Prime Minister and the country's Defense Minister. Among the war crimes that Netanyahu and Galant may be involved in are starvation of civilians causing great suffering, harm and ill-treatment, murder and attacks on civilians. Crimes against humanity include extermination, persecution and other inhumane acts. Khan also requested arrest warrants for Hamas leaders: Gaza leader Yahya Sinwar, deputy commander of the armed forces Mohammed al-Deif and Politburo chief Ismail Haniyeh. Source link Source link

Replacement lithium batteries – charges in seconds and does not explode – Russia today Posting in CHAT: Russia A new type of battery has been developed in Korea - sodium-ion with ultra-fast recharging. Its key difference from lithium batteries is that such batteries can be charged to 100% in just a few minutes, and often faster. It is based on supercapacitor technology, and Russian scientists learned how to make these energy storage devices from hogweed, a plant that is being fought all over Russia. There is no need to wait for new researchers from the Korea Advanced Institute of Science and Technology (KAIST). has made a promising breakthrough in the field of batteries, writes TechSpot. They have developed a new sodium-ion battery that can not only store electricity, but also do it at lightning speed. According to TechSpot experts, the development of Korean scientists can revolutionize the field of portable power sources. Sodium-ion batteries are similar in design to regular lithium-ion batteries, which have three problems - they charge slowly, burn quickly, and burn well. and they are difficult to get rid of. Thanks to an almost identical design, new Korean batteries can be sent to the production line without the need for large investments in modernizing production. In the new batteries, sodium ions replace lithium ions in the cathode, and lithium salts in the electrolyte (the liquid that helps transfer charge between the battery electrodes) are replaced by sodium salts. Korean scientists do not disclose the technical characteristics of their invention. The well-forgotten old sodium-ion batteries themselves are far from the latest technology. But in their original form they are noticeably inferior even to older lithium in terms of charging time and density, so their mass distribution has not yet occurred. But the technology is still gradually gaining momentum, including because the materials used in lithium batteries are 1000 times less abundant on the planet than sodium components (TechSpot statistics. In fact, KAIST specialists simply eliminated the main drawback of sodium-ion batteries - slow speed ). loading speed And they managed to do this with the help of technologies used in supercapacitors - modern batteries capable of storing large reserves of energy in a small volume. You can immediately “pump” energy into them, or you can just as quickly extract it from them. The service life of supercapacitors is practically unlimited. The KAIST team replaced traditional battery cathode materials with materials used in supercapacitors, resulting in a high-energy, high-power hybrid sodium battery that can be charged quickly. Changes were made to the anode to increase the capacity, and an optimized electrode material was synthesized using a special method. You can't heat it with fire. Sodium-ion batteries lack two more fundamental disadvantages of their lithium-ion competitors. Firstly, they are ten times safer because they burn very poorly, and secondly, they can be discharged to zero without consequences and then recharged. This trick doesn't work with lithium batteries - dropping the voltage to 0V usually means you need to buy a new battery or use specialized chargers. The latter, however, do not always help when the battery is 100% discharged and can even cause a fire. Sodium-ion batteries also eliminate the risk of overheating due to a short circuit, write TechSpot researchers who worked on the project, and their solution has a density higher than commercially available lithium-ion batteries. This means that Korean scientists were able to eliminate the problems of sodium-ion batteries with the inability to store the same amount of energy as lithium-ion batteries, having the same dimensions, it was possible to make sodium batteries more compact than lithium batteries while maintaining capacity. According to TechSpot, given all the improvements that KAIST has made to the design of sodium batteries, they are now ideal for use in all types of electronic devices. These batteries are compact, lightweight, safe and charge quickly. They could also have a major impact on the electric vehicle market, which has been experiencing slow growth due to lithium batteries. Electric cars with such batteries charge too slowly and burn too well, and replacing the battery is always, with the exception of warranty cases, a big blow to the wallet. Electric cars powered by sodium batteries will be able to charge in a few minutes - the same amount of time it usually takes to fill a full tank of a passenger car with an internal combustion engine. Automakers, as reported by CNews, are also looking for ways to solve the problem of slow charging of electric vehicles in batteries. At the time of publication of the material, KAIST scientists did not indicate the time of commercialization of their technology. However, the absence of the need to modernize production and the easy availability of components for assembling sodium-ion batteries gives hope that their appearance in technology is a matter of the coming years. Russia also has ideas for creating batteries based on fast charging. on non-standard materials. For example, in 2019, domestic specialists learned how to produce them at a plant that the whole of Russia wants to get rid of as soon as possible. We are talking about the so-called “hogweed” - a weed that, according to many experts, can be dangerous to human health. CNews wrote that Russian scientists have found a way to use the stem of hogweed as a material for the production of supercapacitor electrodes. They tested their idea in practice, and it proved its effectiveness - the results obtained during the research showed that, despite the plant origin of the electrodes, supercapacitors did not lose their properties and could accumulate charge in large volumes and retain it for some time. for a long time Source link Source link

Depardieu released from custody after arrest on stalking charges Posting in CHAT: Russia April 29, 2024, 20:26 Actor Depardieu, detained in a harassment case, has been released from custody RIA Novosti Read 360 in French actor Gerard Depardieu, detained in a harassment case, has been released from prison in Paris. This was reported by the BFMTV channel. “Gerard Depardieu is no longer at the police station,” said the artist’s lawyer Christian Saint-Palais. Women accused Depardieu of sexual assault. Allegedly, in both cases, the artist molested them while working on films. One of the episodes occurred on the set of the film in 2014, the second in 2021. Before this, Depardieu was summoned for questioning. The artist did not admit his guilt in harassment. The lawyers did not comment on the situation.
