But why? The base materials are cheap and easily available, and the synthesis process seems rather straightforward. Why don't they have kilograms of this stuff by now?
- adastra22 3y agoThe synthesis process is not at all straightforward.
- lll-o-lll 3y ago> synthesis process seems rather straightforward They’ve been working on this for years. To me it looks like whatever their process is, they don’t have something that’s repeatable. So maybe a couple of small samples are all there are after 1000s of attempts doing more or less the same thing.
- p-e-w 3y agoSo the groups trying to replicate right now are basically wasting their time?
- lll-o-lll 3y ago> So the groups trying to replicate right now are basically wasting their time? If a few dozen groups all try and replicate, and there is something to replicate, then odds are good someone will get lucky (birthday paradox and all that). Each individual group is definitely wasting their time, but the aggregate time spent may not be a waste.
- sophiebits 3y agoBirthday paradox is about random draws coinciding with each other (hence the sqrt behavior), not a target.
- lIl-IIIl 3y agoThe birthday paradox would only apply if we are interested in one group replicating the result of any other group, not the result of the original paper. It's the difference between "do any people in this group share a birthday" vs "do any people in this group share my birthday".
- mrguyorama 3y agoNo, this still needs replication. A room temp and pressure superconductor being possible at all, verifiably, implies there are probably better versions to be discovered. This could really improve the funding in the area, and labs that attempt replication and fail could benefit from that.
- j16sdiz 3y agoThese are crystals. Getting large (millimeters scale), pure crystal of the required structure is not easy. You can't do superconducting experiments on powder.
