Fun reading!

Continuing on a series of interesting arxiv articles,
Clarification as to why alcoholic beverages have the ability to induce superconductivity in Fe_{1+d}Te_{1-x}S_x claims to have investigated the key components in alcoholic beverages and clarified the mechanism to induce superconductivity in Fe1+dTe1-xSx.

Actually reading this, I agree that they have investigated the key components in alcoholic beverages.
They have mentioned previous work with that material, specifically regarding the presence (necessitating absence) of iron in that material to achieve superconductivity.

Also, they have not experimentally induced superconductivity in that material.

Procedure:
They considered the concentrations of three acids: malic acid, citric acid and β-alanine and water (which are major components of their drinks).

Temperature susceptibility measured to 2K.
Shielding volumes were calculated for the drinks showing increase proportional to concentrations of of the three acids.
X-ray diffraction shows that the drink solutions does not decompose the crystal structure.

So reasonable question  (which they mention) would be how does/why would malic acid, citric acid and β-alanine make things superconduct?
They mention Fe content is interesting, bu these three acids don't contain Fe.

Their procedure raises a question which they have not addressed/supported: what's shielding volume and how is it relevant?
I suppose superconductivity involves conduction without loss, so there's some term that must shield a current from the outside?

Anyway, if alcoholic beverages had the ability to induce superconductivity, that'd be a pretty good party trick...
