The world's first 40000 watt groove laser cutting machine is put into production in China

When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...

BMW explained how to use WAAM (Arc Additive Manufacturing) starting from 2025 to manufacture lighter and stronger automotive components and reduce waste generation, in order to optimize the use of generative design tools.The demonstrated WAAM process uses aluminum wire raw materials directly deposited through laser welding heads, enabling automotive companies to manufacture lighter and more robust...

As a promising imaging modality that combines the high spatial resolution of optical imaging and the deep tissue penetration ability of ultrasound imaging, photoacoustic microscopy (PAM) has attracted a lot of attention in the field of biomedical research, and has a wide range of applications in many fields, such as tumor detection, dermatology, and vascular morphology assessment. Depending on the...

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 ...

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...
