Samsung Heavy Industries Developing a Laser High Speed Welding Robot for Liquefied Natural Gas Ships

Recently, Professor Tian Zhen's team from Tianjin University has made a breakthrough in the field of photoacoustic remote sensing microscopy technology and successfully developed a new type of non-destructive testing method. This technology uses Kaplin high-power femtosecond laser as the key light source, further optimizing the solution to the internal flaw detection limitations of inverted chips,...

AbstractDue to the width of the laser melt pool and the sintering effect on the surrounding powder, the experimental size of the selective laser melting (SLM) sample will be larger than the design size, which will greatly affect the dimensional accuracy and surface quality of the thin-walled sample. In order to obtain SLM thin-walled TC11 specimens with precise dimensions, an orthogonal experiment...

Recently, the team led by Wu Kaifeng, a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Zhu Jingyi, an associate researcher, has made progress in the interdisciplinary field of photochemistry and photophysics. The team directly observed the quantum coherence properties of hybrid free radical pairs composed of quantum dots and organic molecules, achieving ef...
