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...
Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
Archaeologists have long wondered why the people of Anglo Saxon England began using more silver coins and fewer gold coins between 660 and 750 AD. Researchers in Europe now say they have developed a method to help find the answer. This technology combines laser ablation with traditional trace element analysis to match the isotopic abundance of silver bars in coins with known sources of metal ores ...
Recently, the research team of Yang Shanglu from the Laser Intelligent Manufacturing Technology R&D Center of the Chinese Academy of Sciences Shanghai Institute of Optics and Precision Machinery has made new progress in laser welding of new structural materials for high-temperature molten salts. The research team used a high-power laser for the first time to achieve defect free welding of nick...
Customized laser beams focused through transparent glass can generate a small dot inside the material. Researchers from Northeastern University have reported a method of using this small spot to improve laser material processing and increase processing resolution.Their research results are published in the journal Optics Letters.Laser processing, like drilling and cutting, is crucial in industrie...
