Billionaire Mike Cannon-Brookes' plan to export clean energy from Australia to Singapore via a 4,200km undersea cable has gained new momentum after taking control of the stalled project.Cannon-Brookes' Grok Ventures has completed its acquisition of SunCable from the government and is advancing talks with authorities in Singapore and Indonesia, the investment firm said on Thursday. The revised plan...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
It is reported that researchers from the University of Salamanca in Spain have demonstrated a high-order harmonic spectroscopy scheme generated by the interaction between a structured driving beam and a crystal solid target. This work promotes the topological analysis of high-order harmonic fields as a spectroscopic tool to reveal nonlinearity in the coupling of light and target symmetry. The rele...
In a recent study published in the journal AIP Advances, researchers used molecular and elemental spectroscopy techniques such as laser induced breakdown spectroscopy (LIBS), Raman spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy to characterize mines in ancient Egypt.In this study, researchers examined various gemstones that can be traced back to the era of the pharaohs. The team...
The National Key Laboratory of Interface Science and Technology for High end Equipment at Tsinghua University has made progress in the field of magnetic field and laser composite processing - magnetic field assisted laser shock strengthening of Ti6Al4V alloy. The relevant research was published as a cover article titled "Magnetic Field Assisted Laser Shock Peening of Ti6Al4V Alloy" in the journal ...
