Furthermore, the mass of a copper atom is 63.57 times the mass of a hydrogen atom (which is 1.63×10−24 g) so that the mass of 1 m3 of copper, i.e. the density, is 8.56×1028×63.57×1.63×10−24=8900 kg m−3. On alloying, the density of a metal changes. This is ...

Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain our ability to expand the cultivation of crops into ...
The morphological evolution of different topographical features (namely cones, ridges, cliffs, and featureless planes), as developed on bombarded copper surfaces as a function of consecutive doses of mass-separated 12 keV Kr+ ions, has been compared. The doses ranged from 1.2 1017 ions/cm2 up...
