Just ten years ago, fiber laser cutting machines were considered experts in thin plates. The stores quickly realized that they had to invest in them to compete, at least by reducing their instrument materials. For high-quality sheet metal cutting, CO2 laser is still the way to go. Of course, fiber lasers can cut thicker blanks, but the quality is not very good, and their speed advantage almost dis...
Researchers at the University of Bristol have made significant breakthroughs in expanding quantum technology by integrating the world's smallest quantum photodetector onto silicon chips. The paper "A Bi CMOS Electron Photon Integrated Circuit Quantum Photodetector" was published in Science Advances.In the 1960s, scientists and engineers were able to miniaturize transistors onto inexpensive microch...
Through the SOMA project funded by the European Union, organic silicon material expert Aiken has collaborated with research partners and clients to develop a new specialized iron silicon powder that can more efficiently 3D print motor components.Yesterday's electric motor was usually made by cutting and shaping parts from a metal plate. 3D printing can fundamentally improve efficiency and...
Researchers at the Federal Institute of Technology in Lausanne have resolved the long-standing debate surrounding laser additive manufacturing processes through a groundbreaking defect detection method.The development of laser additive manufacturing is often hindered by unexpected defects. Traditional monitoring methods, such as thermal imaging and machine learning algorithms, have shown significa...
Recently, the team of Yang Tao-Yang Xiaoguang, a researcher at the Key Laboratory of Materials Science of the Institute of Semiconductors of the Chinese Academy of Sciences, and Lu Dan, a researcher, together with Ji Chen, a professor at the Zhijiang Laboratory of Zhejiang University, have made important progress in the research of high-power, low-noise quantum dot DFB single-mode lasers.Distribut...
