The USA government has announced that the social networks TikTok and WeChat will be banned in the USA starting from September 20. It’s another step of President Donald Trump’s administration in the clash with Chinese social media, accused of spying on American citizens. In particular, TikTok’s situation is complicated because in recent days the news of a partnership with Oracle arrived, however, it didn’t satisfy the White House, which demands the social network’s sale to an American company. The Chinese Ministry of Commerce accused the USA of bullying. Behind this clash there’s the problem of controlling user activity, the reason why some American social networks are banned in China.

Ethereum is a platform for a well-known cryptocurrency, but out of the blockchain world – the technology behind cryptocurrencies – Bitcoin remains by far the most famous one. However, the growth of Ether (ETH) transactions of this period led Ethereum to become the most used blockchain platform in recent days, surpassing Bitcoin. This doesn’t mean that the value of Ether surpassed its own record and indeed it’s still far from its highest values. For Ethereum it’s an important period also because at the beginning of August a public test phase of version 2.0 will begin.

The Covid-19 pandemic has stopped or at least slowed down many industries’ operations with a number of consequences and ramifications. The shutdown, which is hopefully only temporary, of a factory, is a clearly visible event, but behind it, there may be other events connected to it and less visible. For example, there are important materials in several different industries such as tungsten carbide and silicon nitride: in their case, there are problems connected to production and distribution, but there’s also the problem connected to research on their performance and to the expansion of their applications.
