Недавно опубликованная статья в The Journal of Physical Chemistry Letters исследует динамику обмена воды в пористом кремнеземе с применением методов ЯМР-релаксации. Исследователи впервые использует модель обменно-ориентированной рандомизации (EMOR), которая позволяет количественно оценить влияние обменных процессов между молекулами воды и поверхностью кремнезема на ЯМР релаксацию. В работе варьируется время обмена для молекул H2O и D2O, при помощи добавления фосфата натрия, что позволяет детально изучить, как эти обменные процессы влияют на релаксационные характеристики ЯМР, важные для более точного моделирования взаимодействий воды на поверхностях. https://doi.org/10.1021/acs.jpclett.4c02590

Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read." The SC urges the public to refer to the SC’s I nvestor Alert List before investing. The list contains details of unauthorised websites, investment products, companies and individuals. Members of the public who suspect that they have been approached by unauthorised firms or individuals offering schemes that promise unrealistic returns On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations. 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.
