阳光为什么能高效的蒸发水
#科学

太阳可以很快把水晒干,但为什么阳光比加热炉子更高效?北卡罗来纳州立大学的一项新研究给出了答案:关键是阳光中的振荡电场!研究团队利用计算模拟的方法,系统地分析了阳光的不同特性。他们发现:阳光中本就包含振荡电场,它能极大地加快水分子的逃逸速度。更令人惊讶的是,电场不仅“赶走”了单个水分子,它还能把一整簇水分子——即“水分子团簇”——从液体中分离出来!这效率可比一个个赶单分子高多了。研究者们还比较了纯水和水凝胶中的蒸发差异。结果发现,在水凝胶中,由于交联聚合物链的存在,更多的水团簇出现在水表面附近。也就是说,在这种环境中,电场能更容易“切断”水团簇,让蒸发更快发生。

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

NEWS: Telegram supports Facetime video calls NOW!

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
