Spontaneous supercrystal discovered in switching metal-insulator
A supercrystal formation previously unobserved in a metal-insulating material was discovered by a Cornell-led research team, potentially unlocking new ways to engineer materials and devices with tunable electronic properties. The researchers showed that the atomic structure in the thin-film Mott insulator Ca2RuO4—part of a unique family of materials that can switch between being a metal and an insulator due to quantum effects—forms an anisotropic, organized pattern with multiple spatial periods below temperatures of 200 to 250-degrees Kelvin. The spontaneous supercrystal formation was detailed June 17 in the journal Advanced Materials. "This is a great example of complexity arising from simplicity," said Oleg Gorobtsov, postdoctoral fellow and lead author of the study.

Lost Light/Rodimus
Notes: No, I don’t mean the crew. Unedited bc I’ve already spent way more time on this crack fic than I meant to. Rated G, no warnings apply, 2K.
---
It wasn’t Brainstorm’s fault, entirely.
“How the hell did you make a metrotitan spark?”
Just mostly.
“Well, it’s actually an extremely complicated, delicate, precise procedure,” Brainstorm said as they ran for their lives through shifting, narrowing corridors, Rodimus’ engine gunning to keep up with the jet. “It’s something other scientists have been trying to crack since before the war started, but between the exact measurements of the photonic supercrystal and the pattern of coding charges, no one else ever managed to—”
“Okay, forget how!” Rodimus shouted. “I don’t care about how! Or why! Or even at what point you decided to make a massive t-cog to go with it—”
“Actually, Perceptor cracked that one.”
“—or how you got it past Riptide and the rest of security! I don’t care!” A wall appeared front of them; Rodimus swerved around it while Brainstorm pulled into a neat roll. A wingtip brushed Rodimus’ roof. “Assuming we survive this any other way than First Aid scraping our pancaked frames off a random corridor wall, you’re going to tell the whole story to Megatron, and he can use all the practice he’s had with me to tell you exactly how terrible an idea this was.”
“Pancaked?”
“Earth term. Watch out!”
The hallway to the shuttle bay disappeared behind two shifting plates, and Rodimus had just enough time to brake and avoid being crushed. Brainstorm pulled up and transformed, landing at Rodimus’ side.
“Oh, this isn’t good,” he said.
“No kidding?” Rodimus angled his mirrors to look around, but every glance just revealed fewer directions to escape to. “We’re trapped.”
“Not that,” Brainstorm said. “We’re in the abdomen.”
“Belly of the ship, sure.”
“In root mode, the Lost Light’s power core is situated in the lower decks, under multiple layers of plating and insulation to keep the heat from frying everyone around it.” Brainstorm traced a small circle on the plating just underneath his cockpit, then drew it up, toward his chest. “When Perceptor was designing the transformation sequence, though, we couldn’t quite work out how to transport the core with all its extra plating. So, we just, hm, put a pin in it.”
Rodimus stared.
“So, what you’re saying is—”
Brainstorm pointed to the ceiling.
“The power core is one level above us right now. As soon as the transformation sequence is completed, it’s going to come online. The Lost Light’s designed to handle that kind of output, but not standard Cybertronians.”
“So, right now, this moment, we’re standing in the smelter, waiting for it to come on.”
“More like in front of the smelter after the blast doors have malfunctioned, but yeah.”
“Okay!” Rodimus revved his engine. “Well, that’s no good! We’re getting out of here.” He glanced around again. The walls were thick, but there had to be a weakness somewhere. “Don’t you have a drill gun? Or a drill you reformatted into a gun that can still be used as a drill?”
“I have a regular gun.”
“You do not.”
“I do!” Brainstorm insisted, pulling the standard issue pistol from subspace. “I was just about to see if I could do something about the problem of a finite ammo capacity (spoiler, I could’ve) when Light’s t-cog started spinning. I have others on me, but nothing that’s gotten the Perceptor stamp yet.”
“Everything else you’ve got will kill us if we fire it?”
“Might,” Brainstorm corrected, “they might kill you. Percy just hasn’t had time to test them yet.”
“Okay, fine.” Rodimus glanced around once more, optics falling on one feature he’d thus far overlooked. “You know what? We can work with this.”
It’s a simple fact that if you’re desperate to have floor-to-ceiling windows along the vehicle-accessible corridors of your miles-wide spaceship, they’re going to need to be reinforced. Heavily. A full round of shots fired at point-blank from a non-infinite pistol might be enough to get a crack in it, but that’s about it.
Of course, if you then ram that crack with a Matrix-armored sports car dropped from the undercarriage of a speeding jet, you might get somewhere.
Rodimus hit the window bumper-first, vibrations from the impact traveling in both directions throughout his frame. Whatever he was feeling, though, the window was having a much worse time: the crack stretched and exploded, shards of glass whipping out into the empty density of space. Rodimus went with them, and for a brief second he feared he would never stop going, before strong arms and the sound of thrusters secured him.
::We’re alive!:: Brainstorm’s comm crackled to life in his audial. ::And assuming at least a couple people listened to Minimus’ instructions, we should be looking at a good—oh frag.::
::What? How bad is it?:: Rodimus tried to angle his mirrors, but two teal wings blocked his view.
::It’s fine! Don’t worry!::
::That’s my ship, Brainstorm, of course I’m going to worry!::
::It’s alright, Rodimus.::
::Who was—::
A white hand appeared in front of them, large enough that Rodimus could have done donuts on its palm, large enough to punch a moon clear through. Brainstorm’s thrusters were straining to slow them down while Rodimus’ emergency brake slammed on, but momentum seemed committed to mashing them like a reverse rustbug.
The hand shifted, flipping over so the palm was underneath Rodimus, scooping up until his tires were just skidding across the metal surface. Forgetting to release his brake, his swerved before he came to a stop, swinging around and taking in the full view of his ship as, with a final ripple, her plating shifted into place.
She glowed. From the fuel rods around the corona of her helm and the winding lanes of windows around her arms, legs, and sides, light streamed from her, but not so much that she hurt to look at. Her optic band was a solid magenta and, Rodimus suspected, unseeing, but even that gave off a light that drew the eye, even as Rodimus felt the increased pressure of the hand lifting them up. In their ascent, they passed her chestpiece, the bow of the ship, and through the viewscreen Rodimus saw a decent portion of his crew, staring back out at him.
They came to a halt in front of her faceplate, and from this distance Rodimus could see the wavering patterns of optical lights, perhaps attempting to generate an expression. Ratchet would demand a look at Perceptor’s coding, he thought, a moment before the Lost Light’s voice returned.
::Hello, Rodimus, Brainstorm.::
::You gave her a comm suite?:: Rodimus asked, glancing at Brainstorm.
::Didn’t you check the ident?:: Brainstorm returned. ::She’s using the communications hub.::
::Oh.:: He glanced at her again. ::Can you access all of our major systems like that?::
::Yes.::
::Cool. Neat.:: An independent Cybertronian with the ability to quantum jump. And they’d been doing so well staying off the bad side of this reality’s Galactic Council.
::Do you have a name?:: he asked.
The optic lights wavered, shifting without meaning.
::Of course,:: she said. ::Drift named me Lost Light.::
Rodimus spluttered.
::How do you know that?::
::I have complete access to all in-network records,:: she said. ::My ‘memories’ extend as far back as my registration five million years ago, though they become more comprehensive within the last several decades, starting with the commencement of your quest.::
::Anything anyone ever dispersed via in-house networks, saved to a private console, or was automatically logged by the systems is up for grabs,:: Brainstorm said. ::Makes introductions pretty simple, at least.::
::Sounds like a fancy way of saying she’s got the worst possible first impression of everyone, but sure, that’s an optimistic way of looking at it.:: Brainstorm had climbed off him, so he transformed and took two steps forward. ::I’m Rodimus, your co-captain. Though, you already seem to know that.::
::Yes. I know all of you.:: For a moment, Rodimus thought they were moving again, but it was the large helm tilting forward. ::Thank you, by the way, Brainstorm. Though I unfortunately agree with Minimus Ambus’ preliminary assessment of your actions, I do appreciate this opportunity to be alive.::
::Like creator, like creation, I guess!::
::Wait, you talked with Minimus?:: Rodimus asked.
::Of course. I’m speaking to everyone right now,:: Lost Light said. ::I’ve been looking forward to this.::
::Wow. You’re either going to be Swerve and Misfire’s missing trinemate, or their biggest competition.::
::I do not find either of those options appealing.::
::Oh, yeah, that’s fine!:: He waved his hands. ::Just a joke. You can do whatever you want, now, you’re your own bot. Well, within reason, I guess. We might need to make another new officer position for you, and then—::
::I will continue to perform my duties, Rodimus. You have no need to worry in that regard.::
::Oh, good.:: Rodimus’ spoiler sagged and a few bubbles of trapped air escape his vents. Brainstorm’s scheme hadn’t dehomed them, at least.
::If you wouldn’t mind hearing it, I do have a request.::
Rodimus’ spoiler twitched back up.
::Sure!:: he said. ::After everything we’ve put you through, we owe you, huh?::
::I would prefer you not consider it that way,:: she said. The connection crystalized and strengthened into a private transfer as Lost Light cleaved Brainstorm into his own channel. ::After reviewing the records, I find I admire you, Rodimus.::
He stared.
::Oh?::
::Despite what you call a poor first impression, I have observed a crew that cares for each other and looks after its most vulnerable, with you as the spark that inspires such communal behavior. You act for the good of others, you encourage selflessness and self-improvement. Does that sound correct?::
There was nothing to hide behind on the palm of her hand. That observation could not kill Rodimus’ instinct to flee.
::I, uh. I don’t know?::
A flicker around the optic band again.
::Oh. My apologies. I have only just started to engage in pattern recognition, and it is possible my assessment is—::
::It’s fine!:: Rodimus assured. ::Sorry, you did fine. Um, yeah, I guess you could say all those things about me. Not everyone would, but if that’s what the logs are telling you, you should trust your instincts. Maybe just like, make sure to update them with your own observations?::
::Acknowledged.:: There was a pause, and Rodimus imagined she was sorting the suggestion among her priority trees. ::I will maintain my assessments as an ongoing process. However, if I am utilizing my initial understanding of each crew member as a basis to form a more informed conception of their character, then it is logical to assume that there must be some element of validity to my initial evaluations, correct?::
::Uh, sure?::
::Excellent.:: Her whole visor brightened, a straightforward positive that must have been easier for her programming to calculate than the emotions it had been trying to convey before. ::Then it is not unreasonable for me to hold to my initial conviction that I admire you, Rodimus. If you have time, I would like to get to know you better.::
::Huh. Uh.:: He hated to make assumptions, but the way her visor sparkled seemed more coordinated now. ::Can you give me one moment?::
::Of course.::
He hopped into a channel so well worn it felt like sinking into his own thoughts.
::Rodimus? Are you okay?::
::I’m fine, Drift,:: he said. ::Just, uh, need some advice.::
::Just advice? Not a rescue? Rewind and Perceptor managed to map out a way down to the shuttle bay, if you need an out.::
::No, no,:: he insisted. ::I’m just… I really don’t want to assume anything, but I think it’s possible my ship just asked me out?::
::Oh, yeah.::
::Oh, yeah?::
::I mean, she did,:: Drift said. ::Before you and Brainstorm broke free, she commed everyone, introduced herself, told them her favorite thing she knew about them, then asked about you.::
::Do I… want to know what she asked about?::
::Depended on the person. Swerve got interrogated about whether you’re available.::
::Swerve?::
::The Lost Light Insider pegged him for a rumor monger and she ran with it.::
::Cool. Great.::
::Hey. Really, you okay up there? Tailgate’s halfway through the vents, we can come get you, if you need.::
Rodimus pointed his gaze down to the deck, though he was too far away to see anyone individually. It was possible the ship’s exterior cameras were still streaming to the command screens, in which case Drift would undoubtedly catch his disapproval.
::Please make sure Tailgate doesn’t get squished, I don’t need Cyclonus seeking vengeance against our ship.::
::Sure. But seriously, Rodimus, are you okay?::
Rodimus spun his wheels with a flick.
::I’m fine. I just… isn’t this, I don’t know, kind of taking advantage?::
::I mean, she asked you, and—wait, are you interested?::
His engine heated up and Rodimus started to pace.
::I don’t know! Maybe?::
::Aw, Rodimus!:: He could imagine Drift’s face: goofy smile, softly dimmed optics. ::Hang on, I’m patching Ratchet in.::
::No, hang on, you don’t have to—::
::You’re saying yes?:: Ratchet demanded as the new connection crackled through.
::I don’t know,:: Rodimus insisted. ::I could? She’s attractive. And she knows a lot about me and hasn’t decided I’m worthless slag.::
::Rodimus,:: Drift chided.
::Hey, look, I’m not saying that about myself,:: he countered. ::Just that it’s a conclusion she could have come to, but didn’t. And I guess I kind of like that?:: He shrugged. ::I wouldn’t mind getting to know her. First new Cybertronian we’ll meet for a long time, you know?::
::Sure,:: Ratchet said. ::Follow her lead, but be up front about your expectations.::
::Both of you will have bots looking out for you,:: Drift promised. ::Seems like she and Nautica are already hitting it off pretty well.::
::Alright.:: Rodimus smiled. ::Okay, thanks guys. I think I can handle it from here.::
::Sure you can,:: Drift said.
Rodimus cut the call and switched back to Lost Light’s channel. Brainstorm was wandering around behind him, still engaged in his own animated conversation with his creation.
::Still with me?:: he asked.
::Of course.::
::Great,:: he said, offering her a smile and a flicker of his headlights. ::So, yeah, I’m down to spend more time together.:: He leaned down until he was sitting, crosslegged, on her open palm, brushing the smooth metal with his own hand. ::You can tell me all about what it was like that time we were getting chased by space pirates.::
::I look forward to it,:: she said. The platform of her hand drifted closer, until Rodimus could have reached out and brushed his fingertips against his facemask. He could have felt afraid, then, but he didn’t. Instead, he felt a warm light in his spark as he regarded Light, the familiarity and comfort that came with meeting an old friend face to face for the first time.

Colloidal nanocrystals of metals, semiconductors, and other functional materials can self-assemble into long-range ordered crystalline and quasicrystalline phases, but insulating organic surface ligands prevent the development of collective electronic states in ordered nanocrystal assemblies. We reversibly self-assembled colloidal nanocrystals of gold, platinum, nickel, lead sulfide, and lead selenide with conductive inorganic ligands into supercrystals exhibiting optical and electronic properties consistent with strong electronic coupling between the constituent nanocrystals.

Super-strong magnetic supercrystals can assemble themselves
Verner Håkonsen works with cubes so tiny that nearly 5 billion of them could fit on a pinhead.
[...]
He cooks up the cubes in the Norwegian University of Science and Technology's (NTNU) NanoLab, in a weird-looking glass flask with three necks on the top using a mixture of chemicals and special soap.
And when he exposes these invisible cubes to a magnetic field, they perform a magical feat: they assemble themselves into whatever shape he wants.
"It's like building a house, except you don't have to build it," he says. The magnetic force along with other forces cause "the house to build itself -- all the building blocks assemble themselves perfectly under the right conditions."
