It is reported that researchers from BIAS Bremer Institution f ü r angewandte Strahltechnik GmbH in Germany have reported a comparative study of laser deep penetration welding processes for pure nickel using blue and infrared light wavelengths. The related research was published in Welding in the World under the title "Process comparison of laser deep penetration welding in pure nickel using blue ...
Recently, scientists from the National Ignition Facility at Lawrence Livermore National Laboratory in California produced a burst of energy by bombarding hydrogen pellets with 192 laser beams, briefly reproducing the fusion process that powers the sun. This is a repeat of an experiment in December last year, but this time the scientists generated more energy, with a gain almost double that of the ...
Researchers from the Hanover Laser Center and Leibniz University in Germany reported on the mechanism of increased welding depth during time power modulation in high-power laser beam welding. The related paper titled "Mechanisms of Increasing Welding Depth during Temporary Power Modulation in High Power Laser Beam Welding" was published in Advanced Engineering Materials.Understanding the basic mec...
Researchers have developed a new experimental platform that can measure the light wave electric field captured between two mirrors with sub periodic accuracy. This electro-optical Fabry Perot resonant cavity will achieve precise control and observation of the interaction between light and matter, especially in the terahertz (THz) spectral range. The research results were published in the journal "...
According to a recent study published in the journal Science Advances, it reveals how early mammals grew and developed during critical periods of their long 'life history'. A research team including Queen Mary University of London used synchrotron X-ray tomography technology to image the growth rings in fossilized tooth roots, in order to infer the lifespan, growth rate, and even sexual maturity t...
