| Subject: Scientists Turn Copper into ‘Gold’ — Will Bitcoin Replace as Store of Value? Tue Jan 01, 2019 6:29 pm | |
| Per SCMP, a team of scientists at the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences in Liaoning have developed a method to turn cheap, plentiful copper into a substance that is “almost identical” to gold, accomplishing what alchemists have for hundreds of years believed could be a gateway to endless riches. Lest anyone protest that this sounds like something out of the National Enquirer or one of the more fantastical medieval travel narratives, the study was published in the peer-reviewed journal Science Advances, and the methodology relies on chemical reactions rather than secret incantations. To create the pseudo-gold, the scientists shot a payload of hot, electrically-charged argon gas at a target made out of copper. The ionized gas particles dislodged copper atoms from the target, and these atoms fell onto a collecting device where they cooled off into a pile of microscopic sand — each grain just a few nanometers in size. The scientists then tested the properties of these copper particles by using them as a catalyst in a chemical reaction to turn coal into alcohol. Confirming their research, they found that the nanoparticles “achieved catalytic performance extremely similar to that of gold or silver,” Sun and the other researchers wrote, explaining that it can resist high temperatures, oxidization, and erosion much better than standard copper.
