They say it's a picture of atoms, but what are the atoms: the glowing yellow balls or the entire meatball including the darker red? If it's the meatballs, then why do some have apparently two nuclei?...
These images are generated from processing many out of focus images while scanning across the area. They use the differences between the out of focus images to compute what must have caused those differences.
So this technique is pretty far from being able to capture real time events as it requires capturing hundreds of images to produce a single computed image. The paper talks about how thermal motion of the nuclei is what now dominates the limits of resolution for this method.
There are other ultrafast imaging techniques that can capture essentially real-time chemical reactions, but I believe those don't come close to this spatial resolution.
I could be wrong, but I think XRD requires very pure crystals of sufficiently large size. That can help you ascertain the structure and composition of something you can synthesize and crystalize, but I don't believe xrd can image specific regions of interest like single doping sites like this article talks about.
Synchrotron XRD also has a major drawback in having a very significant equipment requirement that requires being able send samples away for analysis at a dedicated facility. That puts limits on sample preparation and stability time, as well as sharing beam time with lots of other groups.
It's been a while since I've read up on synchrotron xray diffraction though, so there could be workarounds for some of those limitation or I could be misremembering details.
I suspect that what caused the failure is a lack of soft close. When closing a drawer, if the slide is smooth and doesn’t have a stop, then the drawer front gets a huge impulse when it collides with the cabinet body. Since the entire kitchen likely has the same craptastic quality, the first step is to instruct everyone to close the drawers as gently as possible. Then consider retrofitting soft close mechanisms to the drawers. And maybe even start saving up to replace the cabinets because more failures are likely.
You need to look this up specifically for the states involved. It varies. Some neighboring states have reciprocity agreements if they have a major city near a shared border. Frequently what happens is you’ll have to file in both states, but one will give you a non-refundable credit for the tax amount paid in the other.
I suspect that in your situation you’ll end up having to pay the full amount of income tax of the state your employer is in.
Whether that’s legal: states get to do whatever they want to collect taxes.
Can someone explain what the various parts of this picture of atoms are? ( lemmy.world )

If I'm legal resident of a state with no state income tax, but work a W-4 job in a different state that has a very high state income tax...
… is it normal/legal for the state I work in to withhold state income tax from my paychecks?
