Around the poles, ice accumulated over millions of years can reach depths of several kilometers. The undisturbed deep ice preserves information about the past. The air bags and particles trapped in the ice tell scientists what the atmosphere used to be like. This has aroused great interest among paleoclimatologists in glacier ice cores.By regularly sampling the ice core at its depth, they can reco...
With the development of groundbreaking components for terahertz quantum cascade lasers, a huge leap has been made in the field of laser technology. A group of researchers have successfully designed a broadband single-chip external coupler with the potential to redefine the functionality of terahertz QCL.The new external coupler is fundamentally based on planar bimetallic waveguides. Its design is ...
According to the University of Cambridge, researchers have developed a new method for 3D printing metal, which can help reduce costs and more effectively utilize resources. This method, developed by a research team led by the University of Cambridge, allows structural modifications to be "programmed" into metal alloys during 3D printing - fine-tuning their performance without the need for thousand...
Dr. Yongcui Mi from Western University in Sweden has developed a new technology that enables real-time laser beam shaping and control for laser welding and directional energy deposition using laser and metal wire. This innovative technology draws on the mirror technology used in advanced astronomical telescopes.Adaptive beam shaping using deformable mirror technology (Image source: Western Univer...
