As is well known, the outer planets of our solar system, Uranus and Neptune, are gas giants rich in water. The extreme pressure on these planets is 2 million times that of the Earth's atmosphere. Their interiors are also as hot as the surface of the sun. Under these conditions, water exhibits a strange high-density ice phase.Researchers have recently observed one of the stages, called Ice XIX, whi...
Recently, Professor Xu Tingfa's research team from the School of Optoelectronics at Beijing Institute of Technology and Assistant Professor Lin Xing's team from Tsinghua University jointly developed a new type of Opto Intelligence Spectrometer (OIS). The device is based on diffractive neural network technology and achieves precise spectral reconstruction under spatially coherent or spatially incoh...
The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...
When you shoot a laser at a solid-state battery, you find that the particles inside are not thrown into the chaos. This surprised a team of researchers from the United States and the United Kingdom.The team discovered the persistence of memory in ions that help move electricity around solid-state batteries.This discovery has improved the understanding of solid-state batteries, which are candidate...
Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
