  • Towards a universal embedded-atom method: empirically adjusted and consistent set of atomic densities for all elements of the periodic table

    The Hartree-Fock-Slater model of atom has been modified by using individual values of the exchange parameter αex for each atom. Each value of αex was adjusted to reproduce the empirical value of the first ionisation energy of the atom considered. The expectation values of energies and radial functions for all elements of the periodic table have been evaluated on ...

  • Sorting Equipment Focus: Keeping Time

    (From Recycling Today Magazine) In with the new, out with the old. A reversal of an old adage is perhaps the best way to describe the increased demand for America’s scrap metals. The world’s hunger for new cars, appliances and buildings was a boon for steel makers in 2004.  Global steel production exceeded 1 billion tons last year, a record amount. And as the need for “new” steel products ...

  • High-quality plastics from waste electrical equipment

    All over Europe, electrical and electronic scrap is the waste stream showing the highest growth rates. Since electronic equipment contains the most varied kinds of materials, the recycling of such waste involves high demands with respect to separation and sorting processes. The German plant manufacturer MeWa builds state-of-the-art recycling plants for large international waste management ...

  • Why Rare Earth Recycling is Rare (and What can We Do About it)

    Earbuds, touch screens, CFLs with a warm glow, rechargeable batteries and power windows: Most of us take these things for granted. When we do, we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful enough — you probably have ...

  • Conductivity Theory and Measurement

    Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such as salt is dissolved in a liquid to form electrical components having opposite electrical charges. For example, sodium chloride separates to form Na" ...
