Re: Superatom mimics for rare earth elements

What Jay has c&p'ed is the New Age continuation of ancient technology and Alchemy carried out at Penn State. It was likely spurned on by China's monopoly of the global Rare Earth Market.

The two main examples in that facsimile producing art are the well mimickers of Gold and Platinum made up from combinations of cheap & common materials like Copper, Nickel and Tin.

One begins with matching the *proton sum* of the starting materials (29Cu, etc.) with the desired proton # (79Au) in the respective noble elements:

29Cu & 50Sn :::: CuSn-Bronze = 79 ..... 79Au 28Ni & 50Sn :::: NiSn-NickelTin = 78 ..... 78Pt

As is well known, the ancient Bronze (CuSn), and the more modern "platinumy" Nickel Tin (NiSn) alloys can act as poor man's Gold resp. Platinum.

Both alloys have properties that are mimicking the state of the noble metals, and exhibit other desired properties that are not available in the noble metals.

There are a number of other such binary or tertiary alloy whose proton sum of its constituents mimic the macro characteristics of the same proton number element.

All in all, this is highly interesting R&D, that now has incorporated the particle size to mimic desired properties.

All of it is lab work; trial and error. The only theoretical help come from the 150 years old Periodic Table of the Elements by Dmitri Ivanovich Mendeleev (1872).

So, let us see whether any of the Einstein Dingleberries with their curved Space-time or the QMorons with their HUP can predict how to produce the next new material.

And how about those 'heat trapping gases'? Still in the pipeline? I could use some green insulation for my log cabin.
