Paint-On Copperplating? What is this Sorcery?

Article note: Well that's cool and useful. Looks like it's basically a displacement reaction with not-too-nasty supplies. I wish there were text instructions, it _appears_ to be 10 mg Cupric Oxide (pretty sure it's CuO, it's black so it's not CuO2 or Cu2O) dissolved in hot 20ml 85% Formic Acid + 100mL distilled water that reduces on the surface.

In a follow-up to her recent video where she electroplated the gas tank of her motorcycle with copper, Laura Kampf decided to try a much easier method of simply painting on a copperplate solution.

She saw a video demonstrating the technique and wanted to try it out. It appears to work. Amazing. As she points out, this could lend itself to all sorts of applications.

A Dishonest, Indifferent, and Toxic Culture

Article note: Damn. I've been watching this at a distance since it went down, at least the guilty parties are being punished (By the ACM, IEEE doesn't give a fuck about anything but money, and I let my membership lapse this year because I've become so cumulatively sick of their shit), which is more than I expected. It really is a perfect "The incentive structure of academia laid bare" situation.
