On theperiodic tableof elements, copper is situated next to nickel and zinc in the first row of what is called transition metals, which refer to metallic metals with certain properties. These properties include being good conductors of electricity, being resistant to corrosion, being very malleable...
There are a number of factors that made precious metals ideal for use as money. While it could merely be a happy accident that these elements were put to the same use by different societies long ago in humanity's past, perhaps we will find that the ancients knew more than we assume. 2...

The reactions of pyrene with molecular oxygen are investigated for developing kinetic models and oxidation rate kinetics. To determine the molecular properties of reactants, transition states and products of the different species occurring in the pyrene/\(\hbox {O}_2\)system, the Gaussian 03/09 ...
