...carbon, nitrogen, oxygen – in Moon rocks. Our findings suggest the presence of a water reservoir in the Moon which is similar to certain parts inside the Earth’s structure. Furthermore, the distinctive chemical composition of the water in the lunar samples points towards water in the Moon having a common origin with that of the Earth and asteroids. As we look forward...

...carbon pick-up may occur in steel workpieces, leading to a hard martensitic layer. Design: Used extensively for tool and die work, and particularly suitable for irregular slots and cavities and small holes with high aspect ratios. Leaves no burrs. Holes down to 0.05 mm can be formed, but an allowance has to be made of 0.005–0.50 mm side-1 for “overcut”. Holes are...

...carbonate. The clay minerals could have been produced by silicates reacting with ammonia ice. However, if Ceres had formed where it is now, it would not have been able to pick up any ammonia ice to enable such a reaction, because the ice would not be stable. This means that Ceres may have originally formed in the Kuiper Belt on the outskirts of the solar system and then...
