First 3D visualization of an aluminum nanocomposite for the auto industry

Manufacturing cars with strong, lightweight aluminum alloys rather than steel could improve fuel efficiency and extend electric vehicle range, but the material's instability at high temperatures has held the alloys back from widespread adoption. Creating tiny, reinforcing particles of titanium carbide (TiC) directly inside of molten aluminum results in a stronger, more temperature resistant aluminum-based material called a metal matrix nanocomposite. Up to this point, researchers have not understood how these nanoparticles form, or how they interact with other features in the microstructure, hindering production of the material on an industrial scale.

Today is Art Deco Day so all y'alls get a Tumblr formatted mega-post. My 2012 photos of Chicago's Carbide & Carbon Building (now The Pendry Hotel). As you can see from the extreme close up ones, the building is dark green, not black like some folks think. It was intentionally shaped & colored to look like a corked champagne bottle.

A very fun illustration I got to make for Schuttersgilde Kampen :)

The sturgeon comes from a local folktale, here there are two of them shooting carbide.

A young woman sticks her head out the window of a bus which had just arrived in Paducah, Kentucky. She was posing for LIFE magazine photographer Ralph Crane for a 1952 story on the town, which had been dubbed "The Atomic City": in 1950, the US government selected Paducah as the site for a large uranium enrichment facility which grew the town considerably during the Cold War.

A brittle interface with low modulus to improve the mechanical properties of multiphase ceramics

Barium strontium aluminum silicate (BaxSr1−xAl2Si2O8, BSAS) ceramics possess both phase stability and resistance to water vapor corrosion, making them ideal materials for radome technology and electronic packaging. To address the low tolerance of BSAS ceramics to damage and defects, the introduction of nano-reinforcements is an effective approach to enhance their strength and toughness. SiC nanowires (SiCnws) exhibit high strength and hardness inherited from SiC ceramics, along with the excellent toughness and elasticity characteristic of nanomaterials, making them ideal candidates for toughening BSAS ceramics. The reinforcing and toughening effects of nano-reinforcements are primarily related to their dispersion and interfacial bonding. Poor dispersion can result in the formation of closed pores during densification, while strong interfacial bonding can prevent effective crack deflection, thereby limiting the reinforcement and toughening effects of the nanomaterials.

Friends and Family #09

[for Maedhros and Maglor week, hosted by @maedhrosmaglorweek]

“Everybody,” Maedhros’ voice echoed through the cave. “Be quiet.”

Maglor put a hand over Caranthir’s mouth to muffle his whimpering. Fingon hushed the cousins nearest him, scooping sobbing Utrass up in his arms. Celegorm, bleeding from several scrapes courtesy of tumbling down the cliff the rest of them climbed down, held the old mining helmet aloft and tried to ignite the carbide lamp again. Everyone heard the fruitless clicking of the sparker. 

“We’re going to be fine,” Maedhros continued now that he had their attention. 

Six sets of eyes blinked at him in the dark, waiting. Caranthir sniffled again.

“Uncle Fingolfin knows where we went. If we can’t get out, the adults will come looking for us in a few hours. But–” He said, knowing Celegorm and Turgon opened their mouths to object to waiting for rescue– “we’ll get ourselves out before that happens. We didn’t go very far, and Maglor, Fingon, and I’ve all been down here on our own. Celegorm and Turgon, you two need to help us keep the littluns safe so we all stay together.”

“I’m not little!” Curufin objected. This was quickly followed by a thud as he tripped over something and fell.

“I got him!” Eiliaduin assured everyone.

“Thanks,” Maglor said, reaching out blindly with his free hand until he felt someone’s head.

Aredhel screamed. Everyone flinched.

He grabbed her arm. “It’s just me.”

“Oh, sorry.”

Maedhros sighed, long-suffering and already weary. “We’re all going to hold hands and go back the way we came.”

“What about the ledge we came down?” Turgon asked. The darkness did nothing to hide his worry. “I can’t climb back up in the dark.”

“Me neither,” Maglor admitted. He was still horribly short in his mind. Even Fingon was taller than him now, and he was 2 years younger. 

“I’ll help everyone get up,” Maedhros said. “Now, come toward my voice and find a hand to grab.”

With a fair amount of shuffling and bumping and narrowly avoiding falls, they came together. Maglor, Fingon, Turgon, and Celegorm caught hold of the younger cousins’ hands, helping everyone join into a line behind the oldest. Maedhros called off everyone’s name to make sure they were all accounted for, then started shuffling slowly forward.

It was rough at first, but with a little trial and error (and Celegorm telling Caranthir to stop stepping on his feet, which the slightly younger boy insisted he was not doing on purpose) they fell into a rhythm. Maedhros described where they should be at regular intervals, warning when the passage sloped down or up again or the ceiling closed in low enough that they had to crawl awkwardly onward.

Before long—though it felt like an eternity to Maglor, blindly following everyone else from his spot in the back of the line—they arrived in the cavern with the dripping stalactites. Splashing through the shallow pool of mineral-rich water, they found the way forward blocked by a rough wall. 

Maedhros felt his way along the stone, fingers searching for the opening they all slipped through earlier. He found it, a smooth hole at shoulder height, just as he began to worry that he wouldn’t be able to or that he’d accidentally led them into a different part of the cave. Relieved, knowing that it was just a bit further now before they’d see daylight, he said, “We’re almost there everyone. This is the last hard part.”

A cheer went up as they all gathered around him, eager to get out.

“Fingon?” He asked when things quieted down. “You go first and help everyone get reconnected up there. There’s a couple side passages up there, and I don’t want anyone to wander off.”

“Right,” Fingon agreed. “Can someone take Utrass?”

After handing the slightly calmer five-year-old off to Turgon, Maedhros hoisted him up and he scrambled into the mouth of the tunnel. 

“I’m ready,” He said.

Maedhros called for another cousin. 

Soon, Maglor was the last one waiting. He reached out for his brother’s hands. They were rough and strong against his own, confident as they cupped together, forming a step for his muddy foot. Maedhros helped him get up into the trees for years like this when the branches were too high for him to reach on his own. If he was climbing the tree to look for fruits or nuts, he always made sure to find a few extra just for Maedhros. He laughed a little at the bright memory.

“What?” His brother asked.

“I just thought about climbing trees.”

Maedhros chuckled under his breath. A private sound, just for the two of them. “I wish there were plums at the end of this.”

“Aunt Anairë brought lots of jams. Maybe she has plum.” 

In the dark, Maedhros grinned. “We’ll have to ask when we get back.”

With that, he lifted him up.

Maglor climbed over the edge, surprised by the relief he suddenly felt at making it out of the deep dark in the cavern. While it wasn’t much, he could just make out the tracest, tiniest hit of light here. It wasn’t visible from below, but now he could see Fingon’s vague silhouette.

“Come on up, Mae,” His cousin said, gesturing Maglor a few feet up the tunnel so there was plenty of room.  

Maedhros reached over the ledge. There wasn’t anything for him to grab onto, and though he jumped and tried to find a purchase for his feet against the stone, he couldn’t get enough leverage to climb up. He landed in the puddle with a splash and frustrated grunt after every try.

“Is he stuck?” Eiliaduin asked, trying to look back at what was happening from her new spot between Celegorm and Caranthir.

“No,” Maedhros insisted. “I’m not stuck.”

He jumped again.

“Wait,” Maglor said after the inevitable splash. “Grab Fingon and my hands this time.”

“I don’t want to pull you back down,” Maedhros worried.

“You won’t!” Fingon quickly interjected. To Maglor he said, “Sit down and press your feet against the wall.”

When they were wedged tightly into place, they asked him to try one more time. He did, and, grunting and straining, they managed to pull him up. The children clapped and the three of them fell together in a pile of relief and exhaustion. Maedhros hugged them both.

After a moment’s reprieve, they stood up and started the last leg of the journey out of the caves.
