A graph showing the process of single crystal diffraction analysis as a semicircle, starting from a crystal, and continuing with scattering data, Bragg intensities, average structure, and at the end average model.
Every now and then I might post important concepts on single crystal diffraction analysis from my recent review. Today, this wrapped-up version of figure 1 reminds us what we lose in the process, and what we actually gain at the end: a model 💎

Bright green transparent metal-organic framework crystals prepared with copper and a “multipronged” carboxylic acid ligand. The crystals formed blocky roughly rectangular pieces with some very large emerald-like chunks.
Pink/red transparent metal-organic framework crystals prepared with cobalt and a “multipronged” carboxylic acid ligand. The crystals formed as a mixture of long rectangular types and aggregated chunks.
Purple transparent metal-organic framework crystals prepared with cobalt and a “multipronged” carboxylic acid ligand. The crystals formed long slightly blocky needles.
Clear transparent metal-organic framework crystals prepared with zirconium and a “multipronged” carboxylic acid ligand. The crystals formed chunky hexagons.
I don’t think I’ve ever had more fun in the lab than when I was making MOFs myself (and trying to use them for small-molecule X-ray structure determination). So let me celebrate by posting a few of the MOF crystals I prepared:

Kirk was notable for practicing anti-LGBTQ+ and anti-trans extremism, racism, and violent rhetoric.
Among the yes votes was Trans Rep. Sarah McBride.

But the ban on entry appears to also apply to ANYONE with an H-1B currently, and says that petitions must be "supplemented" with a $100,000 fee, so who knows who pays that.

Calling campus police for updates, monitoring alerts, and later evacuating my building, feeling more exposed than before. Just a surreal fear limbo. Sure didn't feel like a false alarm with cops, ambulances, firetrucks, and swat on campus.

There is only one possible ending to this story, and sports aren't the last chapter. I guarantee that if you haven't lost five decades of rights in two weeks, you have no idea what this feels like, so I'm begging you: protect trans kids right now with everything you've got.

The Raghavan Lab will use synthetic + physical inorganic chem., and photochem./photophys., to study tunable metal-metal interactions. We hope to, through M-M bonding, explore opportunities in functional materials, small-molecule activation, (photo)catalysis, and energy storage/conversion. (2/3)

He ridiculed it b/c it was irrelevant to the present discussion, and functioned as a distractor that takes people's attention away from the actual issue.
If at a serious meeting at work someone asks "Is the surface of the sun hot?", is the presenter obligated to answer that stupid ass question?
