Adding a small amount of solid carbon to copper boosts its conductivity

A common carbon compound is enabling remarkable performance enhancements when mixed in just the right proportion with copper to make electrical wires. It's a phenomenon that defies conventional wisdom about how metals conduct electricity. The findings, reported in the journal Materials & Design, could lead to more efficient electricity distribution to homes and businesses, as well as more efficient motors to power electric vehicles and industrial equipment. The team has applied for a patent for the work, which was supported by the Department of Energy (DOE) Advanced Materials and Manufacturing Technologies Office. Materials scientist Keerti Kappagantula and her colleagues at DOE's Pacific Northwest National Laboratory discovered that graphene, single layers of the same graphite found in pencils, can enhance an important property of metals called the temperature coefficient of resistance.

Understanding Conductivity Meters

Electrical conductivity is a measure of a material’s ability to conduct an electric current. In the context of solutions, it refers to the capacity of the solution to transmit electrical flow, which is directly related to the presence of ions in the solution. A conductivity meter, therefore, is an essential tool that measures the electrical conductivity in a solution, providing insights into its…

New, more biocompatible materials for bioelectronic applications

Bioelectronics is a field of research in which biology and electronics converge. In medicine, for example, an external electric current is used to cure or monitor diseases of the nervous system, and also to monitor biomarkers in situ. Devices made of conductive materials are used for these applications. The most widely used conductive polymer so far in energy and biomedical applications is PEDOT doped with PSS, known as PEDOT:PSS. Despite its exceptional properties, new conductive materials that can improve some of its limitations, such as biocompatibility, still need to be developed. A study conducted by CIC biomaGUNE's Biomolecular Nanotechnology group is proposing a mechanism for doping PEDOT using a robust engineered protein (PEDOT:Protein); the outcome is a hybrid material with ionic and electronic conductivity, which is quite similar to PEDOT:PSS in some cases. The paper is published in the journal Small.

I haven't had any time to draw this week between working extra hours at the gallery and musical tech week and I teach at a music camp next week! So instead I wanted to share what it looks like to be in an orchestra pit (especially for people who have never seen one before). The conductor is on a platform and the opening allows the conductor to see what's going on stage so they can cue both the pit ensemble and the cast ensemble on stage. I've had a little experience conducting the end of Handel's Alcina and it was SO NEAT seeing everyone and the stage so close up, while being able to work with the pit musicians. I always joked its the best seat in the house (also the most nerve-wracking)

tbh, this pit is one of the nicest I've been in, they're usually just concrete and dust 😭 the other one I usually play in also has a low ceiling so I can't pull my endpin out and use a stool for playing so I have to play like a literal gremlin 😂

This is what it's supposed to look like:

Here's me with the worst posture and hoping my professor doesn't come down to see this atrocious technique:

I've played in a lot of musicals, some of my favorites being Elf, Sound of Music, Ride the Cyclone, Newsies, and recently Beauty and the Beast! My favorite opera to play in was Puccini's Gianni Schicchi, which is an absolute riot of an opera (it's basically Weekend at Bernie's).

Y'all already know how much I adore Merlin but y'all also know how much I hate the Merlin writers. Just simply because they could have done more to add to the plot and they just didn't,

I'm not even talking about Morgana not being corrupted or Arthur not dying (although I want to.) because it really was necessary to the plot, what I am talking about is the plot holes,

The thing that upset me most when watching merlin, the thing that made me stare confusingly at my shitty laptop screen over and over,

The extreme lack of blood.

Now don't think I'm psychotic or anything please, it's merely logic.

Am I supposed to believe that this knight just stabbed a dude and the blade comes out completely clean? Am I supposed to believe that this one girl hit her head on a rock and didn't bleed AT ALL?? just like that??

Like there was a bit of it in the earlier seasons (bloody bandage over chainmail, what the fuck.) but then nothing??

Like I get it was supposed to be a family show (Harry styles reference) but come on. You already stabbed someone, at least make it a little bit more realistic.

COME ON PEOPLE SHOW ME SOME BLOOD

thank you all for listening to my rant<3

Whumptober day 4- Shock

Ok I did as much research on this as possible and idk if it is actually accurate but I tried. Some of the stuff that is inaccurate can be assumed because they don’t know what they’re doing lol. Anyways, king of the Gerudo stuff! Centered around Orman, Ammon, and Terrako! Important to note that Ammon has a Sheikah prosthetic. Also fair warning, there is an electrical shock. Lofty, you know what’s about to happen….

~~~~~~~~~~~~

Terrako sprinted across the ruins, hopping when he reached a strange looking pedestal on the other side. Orman and Ammon slowly followed the little guardian, cautious of their surroundings. They were investigating ruins found near the castle, and Orman was surprised at how unique the ruins were. He’s seen many Sheikah ruins, and even the legendary Zonai ruins, but they didn’t look anything like this. Inside the ruins, there were strange lights that lit up the place, and even though it was filled with debris, it was surprisingly empty, save for the pedestal Terrako was at.

“What is this place?” Ammon muttered underneath his breath. Orman shrugged and walked over to Terrako, noting an electric circuit near a door.

“What is that?” Ammon asked.

“Dunno. Looks like it keeps the door open.”

“How is it still working after all these years?”

“I don’t know.”

Ammon put his hands on his hips and gave Orman a teasing smile.

“Why don’t you know anything?”

“Because I like to remain blissfully ignorant. Now come on.”

Ammon stared at the door for a moment before catching up to Orman.

“What exactly are we looking for anyways?” He asked when he reached the pedestal.

“Dunno, we need to investigate this place and report back whatever we’ve found, so that’s what we’re doing.”

“Investigate… investigate what?”

“Investigate something, I don’t know. Didn’t you listen to Rhoam during the briefing?”

Ammon scoffed and crossed his arms, looking around for a moment. “Welp, there’s nothing here. We can go home now.”

“Hold on now, we haven’t seen everything.”

Ammon groaned and spun around, staring down the empty room. “It’s just an empty room.”

“An empty room with technology still working! I’m sure that’ll be useful information.” Terrako beeped in response and Orman rubbed his little head. “See? The guardian agrees with me!”

Ammon rolled his eyes. “Just get him to record everything so we can leave.”

“Sure thing,” Orman put his hands on his knees and looked at the little guardian. “Ok Terrako, be a good little guardian and record everything so Ammon doesn’t blow a fuse!”

“Hey!”

Terrako made some beeps that Orman assumed was giggling, and he chuckled while Ammon huffed.

“Just wait until Rhoam hears about this. Harassment while on the job is no joke, you know!”

Orman smiled and rolled his eyes while Terrako looked around at some debris. He himself stared at the pedestal, having to agree with Ammon that there was nothing special of note here. He watched Terrako while Ammon continued to complain, curious at what the guardian was doing. Terrako studied every piece of rubbish and debris left in the ruin, and the little guardian found itself near a wall with a strange mark on it. Orman titled his head and walked over to Terrako, eyeing the symbol.

“What is that?” Ammon asked, not moving from his spot. Orman knelt down and brushed his hand against the symbol.

“You ask a lot of questions, Ammon.” He pulled back his hand to look at the dust on his gloves. Ammon scoffed and turned back around.

“I ask a lot of questions you don’t know the answers to apparently,” he grumbled to himself.

“It’s a mysterious ruin that has stuff we don’t understand, how do you expect me to know everything?”

“I don’t know, why don’t you know?”

“I’ve never seen it before!”

“Sounds like a weakness to me…”

“You’re a weakness to me.”

“No you are!”

Orman burst out laughing and Ammon did the same. Such ridiculous banter, what were they? Children? Terrako made a beep noise and Orman rested his hand on his head.

“What is it, little one?” He asked, and Terrako continued beeping, staring at the symbol on the wall. Orman narrowed his eyes as Terrako’s beeping got strange.

Suddenly, a bright light appeared, and electricity burst out from the symbol, hitting Terrako. Orman yelped and jumped back from the guardian as electricity spewed out of him. The lights in the ruin went out one by one, and all the technology started to spew out electricity and shutting down. Including…

Orman gasped as he spun around and saw Ammon’s prosthetic arm spew out electricity. His whole body convulsed and he collapsed to the ground, his muscles continuing to spazz.

“AMMON!” Orman cried, running to his friend. He grabbed his spear and brought it down on the emergency release button on the prosthetic, releasing it from Ammon’s arm. He ripped Ammon’s sleeve off and threw the prosthetic far away from both of them. “Ammon,” his voice shook as his hand hovered over his friend. His eyes fluttered open, and he stared up at the ceiling, dazed. He wasn’t unconscious, that was good, but it didn’t mean that the injury wasn’t serious. Orman listened closely to his breathing as he checked Ammon’s nub, cringing at the burns on where the skin was in contact with the prosthetic. That looked painful.

“Ok,” he whispered, “what do I do, what do I do?” He stared at the arm for a moment, then reached into his pouch and grabbed a bright bloom seed, smacking it on the ground to light up the area he was in.

“Ammon,” he said as calmly as he could, and Ammon looked over at him. “Are you feeling alright?”

Ammon frowned, taking in a shaky breath. “I—I can't feel my arm…”

Orman stared at him for a moment, then pursed his lips. “Which one? You’re kind of missing one of them.”

Ammon glared at him and Orman looked down.

“I guess you still have some of it…”

Ammon took in another shaky breath. “It feels… numb…”

“Well, I’m not surprised. Just focus on breathing alright? I’ll take care of this.”

Ammon nodded slightly, and Orman listened to his struggled breaths. That wasn’t good that he was struggling to breathe, but he could worry about it when it got concerning. He pulled out his canteen and began pouring it onto his burns. When his water emptied out, he grabbed Ammon’s canteen and emptied that as well. He then grabbed bandages he had in his pouch and gently laid them over his burned nub. He checked Ammon’s breathing again, and it seemed to have evened out.

“Ammon? How are you feeling now?” He asked.

Ammon shuddered and squeezed his eyes shut. “Like sh—“

Orman jumped when he heard a loud beep coming from Terrako, and he spun around to see the little guardian beginning to wake up. He sighed, and looked down at Ammon who was beginning to sit up.

“It’s just Terrako,” he muttered, and Ammon nodded.

“Ok… we should get out of here before something like that happens again,” Ammon said, laying back down when he wasn’t strong enough to sit up

Orman looked at the door that they came through and sighed.

“I don’t think that’s gonna happen any time soon.”

“What do you mean?”

Orman stood up and walked over to the door. “The door is shut.”

Ammon groaned. “Are you serious?”

“All the technology here shut down, including the door that you showed no interest in earlier.” He looked over at Terrako who was beeping slowly and barely moving. “I doubt he could open up this door in his state.”

“Wonderful… we’re stuck here…”

Orman walked over to Ammon and watched him carefully. He looked exhausted, and his expression was pinched in pain.

“You alright?”

“No…”

Orman rested his hand on his shoulder. They needed to find a way out, Orman would feel much better if an actual doctor took a look at him. Maybe princess Mipha or Queen Kailani would be able to help him. But he couldn’t do anything while stuck in here. He looked over at Terrako who began to crawl towards them, and he hummed.

“Terrako, do you have enough energy to call for help?”

Terrako beeped and Ammon sighed. “Shouldn’t he… save his energy… to open up the door?”

“It might take too long to do that. If we could call for help on the Sheikah slate, maybe someone can come for us?”

“Will that… even work?”

“I don’t know! Technology is weird, so it might!”

“Ah… well… let’s hope… so…”

Orman looked at Ammon worried as he began to drift off. He panicked for a moment and shook him gently.

“Hey, I don’t know if it’s safe for you to sleep, Ammon.”

Ammon groaned and kept his eyes closed, and Orman shook him again.

“Come on Ammon, please don’t fall asleep. I—I don’t know if I’ll be able to wake you up.”

Ammon opened his blue eyes and gave Orman a blank look. Orman sighed.

“I’m sorry, I’m sure you’re tired, but I’m not taking any chances until we can get out…”

Ammon sighed, annoyed and rested his head back, staring at the ceiling. Orman smiled slightly, then looked back at Terrako, who was barely moving. He didn’t know what the right thing to do was. They needed to get out to help out Ammon, but Terrako seemed to have used up all his energy on crawling towards them. Waiting for him to be strong enough to send a signal or to open the door would take too long, but what else was he supposed to do? And which one would be the fastest option? Orman groaned and leaned back against the rock, feeling his mouth drying up. Just great. He used up all of his and Ammon’s water to deal with the burn. They really couldn’t stay for long. Terrako beeped and began crawling to a wall, examining it.

“Hey, don’t send another electric shock through the building,” Orman warned. Terrako beeped again and clawed at the wall, and Orman gasped when some of it crumbled away. He shot up and knelt at the wall, pushing some of the rocks away. He felt a draft from a gap in the rocks and he cheered. “I think I found a way out!” Terrako made an offended beep and Orman chuckled. “Sorry. Terrako found a way out.”

Ammon cheered tiredly as Orman began moving the rocks out of the way, feeling the fresh air hit his face as the wall crumbled away, and soon there was a big enough hole for Orman to crawl through. He jogged over to Ammon who had his eyes closed, and Orman’s heart skipped a beat.

“Hey,” he shook him, a little too aggressively, and Ammon groaned. “I’m sorry, but I need you to stay awake.”

Ammon glared at him, lifting himself up shakily. Orman helped him sit up and he pointed to the hole.

“Do you think you could crawl through that hole?”

“Yeah, yeah I can do that,” Ammon muttered, slowly standing up with Orman’s help. But when he took a step, his knees buckled, and Orman nearly yelped when he caught him.

“Ok, just wait here…” Orman gave Ammon a pat on the shoulder before standing up and grabbing Ammon’s arm. He then took his belt and Ammon’s belt and strapped the exhausted Terrako to his chest. He swung Ammon’s arm over his shoulders and walked over to the hole.

“I’m fine, Orman. I can crawl through on my own,” Ammon said, sounding more sure of himself this time. Orman nodded, figuring Ammon needed to get used to his legs a little more. Orman went in first, sighing with relief when he was outside, and helped Ammon crawl out. He stood up, helping Ammon on his feet and looked at the castle.

“How are we gonna explain this?” Orman muttered to himself, thinking about what they found at the ruins. “The weird electrical shock, the symbol that caused all this… all of it…”

“Just tell Rhoam Terrako did it,” Ammon said, causing Terrako to make an offended beep. “Hey, I’m not technically wrong.”

Orman chuckled at the two and pulled Ammon’s arm slightly.

“Well, we have time to figure it out, come on, you need help.”

Ammon nodded and stuck close to Orman’s side as they began walking towards castle town. Orman kept a close eye on his dear friend, the feeling of worry never really going away even as he walked along the field. But he supposed that there was not much else he could do except to make sure he was well enough to make it to a healer. Until then, all he could do was worry.
