For this reason, gold is often used in key areas – such as coating connectors and in the bonding wires used to connect a silicon die to the pins that form external connections. But oxidation and corrosion on its surface can lead to increased electrical resistance and limit the lifespan of components in some cases. The boffins developed this method along with colleagues at Sungkyunkwan University, also in Korea, and Mississippi State University in the US, and the research behind it is described in a paper published in Nature.Ĭopper is used pretty much universally in electronics because of its excellent electrical conductivity, from wiring to the tracks on circuit boards. The academics at Pusan National University in South Korea say they have developed a method to fabricate atomically flat single-crystal copper thin films, and that this offers semi-permanent resistance to oxidation. If they're right, this could potentially allow copper to replace gold in electronics, leading to lower costs and, ultimately, cheaper components.

Based on your routine, Siri can even anticipate what you might need to help you breeze through your day. Siri can do it all without your ever having to pick up a device. Scientists claim to have found a way to stop copper from oxidizing. Siri is a faster, easier way to do all kinds of useful things. However, observers suspect ByteDance has stopped using Alibaba Cloud in order to satisfy governments outside China that TikTok does not expose users to Beijing's snooping. The app is so popular that Facebook last week even rated it as a threat to its advertising revenue.Īpple maintains that it offers Chinese iPhone owners splendid security, despite China's pervasive surveillance of its citizens. TikTok, in all its incarnations, was rated the single largest source of web traffic in 2021 by Cloudflare, ahead of even Google, Amazon, and Netflix.

And even that market share was largely the result of Huawei's involuntary exit from the high-end handset business thanks to US sanctions. For Apple, the benefits of the arrangement are clear: Douyin has over half a billion monthly active users in China, but the iPhone has just 23 per cent market share in the Middle Kingdom.
