Ученые лаборатории химии технеция Института физической химии и электрохимии РАН изучили подверженность биообрастанию и коррозииметаллического технеция. Выяснилось, что жизнедеятельность бактерий на первом этапе провоцирует коррозионные процессы, но через некоторое время продукты метаболизма и мертвые микроорганизмы покрывают поверхность металла подобно пленке и процессы коррозии останавливаются.

Unlike Silicon Valley giants such as Facebook and Twitter, which run very public anti-disinformation programs, Brooking said: "Telegram is famously lax or absent in its content moderation policy." Recently, Durav wrote on his Telegram channel that users' right to privacy, in light of the war in Ukraine, is "sacred, now more than ever." So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee. 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.
