Литий-серный аккумулятор сохраняет 80 зарядной емкости после 25 000 циклов Международная группа инженеров и материаловедов разработала литий-серную батарею, способную сохранять 80 своей зарядной емкости после 25 000 циклов. Их статья опубликована в журнале Nature. Чтобы сделать батареи меньше и легче, инженеры постоянно ищут новые материалы. Такие усилия, как правило, сосредоточены на электродах, где литий удерживается другими материалами. Поиск лучшего материала для https://web-deposit.com/component/k2/item/100167

Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea. Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegram’s FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links.
