BEIJING, Dec. 19 (Xinhua) -- A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology.This photo taken on Dec. 15, 2023 shows a Twist Boron Nitride (TBN) crystal placed on a piece of fused silica in Peking University, Beijing, capital of China. A team of Chinese rese...
Recently, the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of composite based picosecond mirrors. The related research results were published in Optics and Laser Technology under the title of "Hybrid Material Based Mirror Coatings for Picosed Laser Applications"....
In the U.S., one in five of the 37 million adults who has diabetes is not aware of it (according to the U.S. CDC – Centers for Disease Control & Prevention). Current methods of diagnosing diabetes and prediabetes usually require a visit to a doctor’s office or lab work, both of which can be expensive and time-consuming. Now, diagnosing diabetes and prediabetes may be as simple as breathing. ...
Semi light, partially matter quasi particles, known as excitons polaritons, can easily bypass obstacles and condense into a single coherent state - both of which are characteristics of topological insulators. Researchers from the United States and China have developed a new technology to manufacture microcavities from chloride based halide perovskites. They expect this work to lead to a new type o...
Recently, four research groups from the University of Science and Technology of China, namely Yao Hongbin, Fan Fengjia, Lin Yue, and Hu Wei, have collaborated to make significant progress in the field of pure red perovskite light-emitting diodes (LEDs). The team independently invented the Electrical Excitation Transient Spectroscopy (EETA) technology and used it to reveal that hole leakage is the ...
