Водная батарея на основе йода показала удельную энергоплотность 1200 Вт*ч/л
По сравнению с литиевыми аккумуляторами, удельная энергоплотность которых 700 Вт*ч на литр, у новых батарей на основе йода и брома этот показатель намного выше — 1200 Вт*ч/л. Вдобавок они безопаснее. Разработка позволит использовать водные батареи в электромобилях, утверждают специалисты Академии наук Китая.

One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. Some people used the platform to organize ahead of the storming of the U.S. Capitol in January 2021, and last month Senator Mark Warner sent a letter to Durov urging him to curb Russian information operations on Telegram. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup.
