Breakthrough Chinese Crystal May Revolutionize Precision Navigation

Chinese scientists have engineered a breakthrough in fluorinated borate crystals, paving the way for ultra-precise nuclear clocks capable of functioning without GPS. By achieving a record-breaking laser wavelength of 145.2 nanometres, this innovation surpasses the previous 1990s-era standard, bringing such clocks closer to becoming portable technological realities. Nuclear clocks, unlike traditional atomic ones, operate at the atomic nucleus level, offering unprecedented precision even in enviro
