Science Museum, London Atomic Clocks Osaka Station clock. Japan Atomic clocks are currently the most accurate time-measuring devices, used to ensure accuracy during radio wave broadcasting, in global navigation satellite systems, and in global time distribution services. The atoms used in these clocks...
19. These diagrams represent the gases helium and hydrogen. A Helium gas exists as atoms and hydrogen gas exists as molecules. B Helium gas and hydrogen gas both exist as molecules. C Helium gas and hydrogen gas both exists as atoms. D Helium gas exists as molecules and hydrogen gas exists...
9Altmetric Explore all metrics Abstract Over the past ten years, the search for compounds combining the properties of semiconductors and ferromagnets has evolved into an important field of materials science. This endeavour has been fuelled by many demonstrations of remarkable low-temperature functionalities...

81Kr has been recognized as an ideal tracer for groundwater dating in the 50,000–1,000,000-year range, but its low abundance (~103 atoms/L H2O) has made routine measurement nearly intractable. We have applied a new analytical method, atom-trap trace analysis (ATTA) (Chen et al., ...
