Gold Reinvented: Stanford Scientists Uncover Exotic Chemical State in New Material
A form of gold that does not occur stably in nature is at the heart of a new crystalline material with intriguing properties.
Stanford scientists have synthesized a rare form of gold, Au2+, stabilized by halide perovskite, with potential applications in electronics and energy sectors, linking their findings to Nobel laureate Linus Pauling’s earlier research. https://scitechdaily.com/gold-reinvented-stanford-scientists-uncover-exotic-chemical-state-in-new-material/#gold#exotic#halide#perovskite
With so many tight matches, it’s going to take us a day to put together the traditional Victory Parade. Please feel free to celebrate (or mourn) and we’ll see you tomorrow.
PSA:
While #Zircon continues to have a strong lead, the ratios are shifting and we’re seeing an uptick in the proportion of #Perovskite votes. #MinCup23 is far from decided!
32 minerals have battled for your hearts, but only one can claim the Championship. Will it be #Zircon, the eternal timekeeper, or #Perovskite, the cubical rain on brown dwarf stars?
I don’t know what @vickyveritas is going to do when two of her favorite minerals come up against each other in the final battle for the #MinCup23, but let’s find out by quickly voting for #Perovskite before 4:00 Pacific Time!
It’s a near-tie with just 5 votes separating #Stibnite and #Perovskite with just 2.5 hours left in the match.
The last few #MinCup23 wins have been secured by direct electioneering through personal networks. You want your mineral in the Finals? Bring in new voters to your side!
Your vote for #Perovskite is a vote for the future and its infinite possibilities. #VoteTheFuture#MInCup23 (edited to add links to articles graphics were published in to ALT)
The non-detection of #perovskite in non-stars shows that it's there.
Cool red dwarf stars have deep absorption bands from TIO gas in their atmospheres. In yet cooler brown dwarfs those bands have disappeared: opaque perovsite dust has condensed, making the titanium invisible.
Almost halfway through the voting window for the second semi-final in this year's Mineral Cup and the Fortress of Solitude just has the lead over the Borg Cube, but the difference is so little as to be practically negligible.
How did I vote? Well, I like Star Trek, I like the Borg, but I also like to be contrary, so #Stibnite got my vote over #Perovskite in this case.
This #perovskite Borg-like crystal can have complex faces, In fact, perovskite has a wide range of morphologies. Perovskite rains from stars, and perovskite structure fuels brilliant new technologies. #VoteTheFuture#MinCup23
#Stibnite vs #Perovskite?
I know I'm supposed to care, but I really don't.
Pick one. Vote. Or not.
And #Zircon? Yawn, Whatever.
Yay....
All that's left are expansion teams. #MinCup23
#MinCup23 SF2 is a clash between two mysterious minerals!
Ancient eyeliner & antimony ore #Stibnite bewitches with its iridescent blades, while futuristic #Perovskite rains on stars & tantalizes technological possibilities.
