Pb -> Au


As I was digging through Paracelsus' writing , I noted his tantalizing discussion of Alkahest.

It occurred to me that Alkahest, if slightly deactivated by perfusion of Phlogiston,
might effect transmutation on the surface of lead foil.

Semi-empirical modeling at the PM6 level suggest a mildly endothermic reaction (<10 kcal/mol) but the ab initio kinetics simulations on Pb clusters predict a very slow reaction rate.

This means that the lead should be finely divided, perhaps
by generating elemental Pb <i>in situ</i>, or using a suspension of precipitated Pb, at the very least.

Reaction rates in heterogeneous media can sometimes be improved using Type-1 or Type-2 sonochemical conditions.

In implementation, this means dropwise addition of a Pb suspension into a hazmat vessel agitated by a 40kHz ultrasound bath.

Suggestions?

Ssssh.

Yer suspozedta go along with it, maybe suggest that it's in the wrong section.

So this is what happens when centuries of knowlege become interweved together in the mind of an immortal. I'm on to you arsphenamine.

I guess this is the part where

That arsphenamine's a spy! He's come here to give us false information on how to transmute gold! (Hint: the Alkafest should be finely powdered).

It is possible to transmute lead into gold, but it takes more energy than it is economically worth.
One other potential option is a type of thermonuclear bomb that would also contain a segment of normal hydrogen, and would utilize the wakefield effect to accelerate the resulting positrons to high energies. These high energy positrons could transmute a portion of a lead shell into gold. But I am not exactly sure how the gold would be recovered, as it would be widely dispersed, and mixed with a fair ammount of radioactive byproducts from the fission initiator.

You forgot the part where you

  • hug the trees and claim personal inerrancy like some self-proclaimed pagan high priest
N.B. Amazingly, these two are both mirror images of each other and not mutually incompatible. Sort of like spin-up and spin-down. Or, more apropos, like Thing 1 and Thing 2.

Close, but no cigar. Precipitates aren't going to cut it. You'll want Pb nanoclusters -- 7-atom clusters, to be precise -- and they'll need to be carefully distributed in vacuum.

I'm not going to to spoon-feed you; you'll have to figure out the correct distribution on your own. You wouldn't be too far astray were you to consider the family of icosohedral stellations and their duals. You'd also do well to teach your self some physics (specifically metaphysical chemical kinetics), learn to do the basic lab procedures of creating and maintaining Bose-Einstein condensates (your Pb nanoclusters), and that in turn means mastering laser tweezer techniques. Given all that, you'll still face the problem of selecting your laser tweezer frequencies given the five distinctive emission lines of ordinary Pb atoms at 357.2, 364.0, 368.3, 373.9 and 405.8 nm. The 405.8 nm peak, the emission line most used for Pb analysis owing to its strength, involves -e transitions from 7s1 3P to 6p2 3P, and for that reason clearly can't be used. Further, as the Pb clusters are Bose-Einstein condensates, QM consideration must be given to spectral line broadening and displacement.

Oh, and two more hints:
1) the pentagons/pentagrams in the distribution shells are critical;
2) Unless you have an astonishing fume hood, autoclave, and vacuum set up, I would strongly advise not experimenting in this area unless you have a LOT of open space. In fact, I'd feel much better, all things considered, if you would promise not to try this inside the orbit of Neptune.

And next time, UTFSE! And cite book and verse, the next time you mention Paracelsus; you'll get treated much more kindly by the geezers (and you know who you are!).

Oh piss off. The 7 atom clusters collapse to a very stable D5h point group with a &Delta;H<sub>f</sub> around -700 kJ. No way will that react with anything.

A 'dirty' (viz, weakly self-orienting) precipitation produces a great variety of cluster sizes. Surely one of them may transmute in a prototypic effort.

This is *research*, man!

Don't care. This is to be run between 273 and 373K as a LENR.

The conjecture is that a phlogistickated Alkahest may engender an intense <b>bogon</b> flux within the reaction vessel. Bogons, the supersymmetric pair particle of cluons, are an intuitively obvious choice...particularly today.
uh, rather, yesterday.

You are too generous. There were three.

Hmmn. Until I'd encountered bogon-initiated LENR's, I'd thought the reaction was best performed inside the orbit of Mercury. ...*well* inside its orbit, in fact.

zOMG! I love that paper.

Completely ignoring the jargon-laden tongue-in-cheek premise in service of scathing sociopolitical commentary, the chemistry just rocks.

Using Cr and Mo organometallics makes for a fascinating bit of preparative chem. Intellectually very savory.
