[quick news] the existence and growth mechanism of two-dimensional ice in 2020 / 1 / 3 has been confirmed for the first time

The existence and growth mechanism of two-dimensional ice has been confirmed for the first time in the past hundred years, 18 kinds of three-dimensional structures of ice have been discovered, among which the most common is the hexagonal ice phase, such as falling snow, summer thawing ice, thick ice layer in the Antarctic But whether there is stable two-dimensional ice in nature has been lack of exact experimental evidence The research team of Peking University, University of Nebraska Lincoln and Chinese Academy of Sciences, using high-resolution qplus type atomic force microscope technology, confirmed the existence of two-dimensional ice for the first time in experiments, and photographed the formation process of two-dimensional ice with atomic level resolution, revealing its special growth mechanism The results were published in the world's top academic journal Nature on Tuesday According to Jiang Ying, the friction between materials can be reduced by using two-dimensional ice In addition, two-dimensional ice can be used as a special two-dimensional material, providing a new platform for the study of high temperature superconductivity, deep UV detection, frozen electron microscopy imaging and so on Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-01/03/content_.htm?
