A team of researchers from the URV and the RMIT University (Australia) has designed and manufactured a surface that uses mechanical means to mitigate the infectious potential of viruses. Made of silicon, the artificial surface consists of a series of tiny spikes that damage the structure of viruses when they come into contact with it. The work is published in the journal ACS Nano. The research has revealed how these processes work and that they are 96% effective. Using this technology in environments in which there is potentially dangerous biological material would make laboratories easier to control and safer for the professionals who work there.

Two-faced solar panels can generate more power at up to 70% less cost

Researchers have built a new kind of two-faced (bifacial) panel. They used single-walled carbon nanotubes as both front and back electrodes. These tubes are just 2.2 nanometers across. That is slightly thinner than a strand of human DNA. A piece of paper is thicker than 45,000 nanotubes stacked on top of each other. The study is published in the journal Nature Communications, and the team included Surrey scientists working with colleagues at the University of Cambridge, the Chinese Academy of Sciences, Xidian University, and Zhengzhou University, China. Dr. Jing Zhang, research fellow at Surrey's Advanced Technology Institute, said, "Our bifacial cells can harvest sunlight from both front and back panels. This generates more energy and depends less on which angle the light hits them.

Long post ahead! (It got out of hand, this is very wordy)

So! I've mentioned his second prosthetic. I've spent a while trying to draw some sort of visual aid to my explanations since I'm not the best with words lol-

I also might have burned myself out a bit but anyway-

Here's what i came up with!

Individuals, backstory, and info under the cut!

Backstory - prosthetic - random notes

How about a little storytime then?

Leo was 23. He and raph were leading a supply run, and everything was fine until they bumped into sister krang, and she brought backup. How lucky amirite?

Lets fast forward a bit towards the end of the battle, troops were fighting hounds, zombies, tech - you name it, they fought it. And while that's happening, Raph had taken on sister krang herself in an attempt to stall for everyone to escape, and leo was trying to make a path through the chaos for the troops.

But no matter his size, raph wasn't strong enough to take on sister krang alone. Leo knew this, raph knew this, She knew this. Leo started making his way over to raph, sprinting and teleporting left and right, getting glimpses of that stable red and her sadistic smile.

When he was almost there, leo got knocked back a few hundred feet by a sudden explosion, knocking him out for a minute or so

Miraculously he was fine when he came to and started his mad dash towards raph once again, but before he could reach him, sister krang reeled her hand back and plunged it straight into his construct, dead center.

Leo screamed when his construct started falling apart, but raph only smiled at him before it fizzled out completely. Then sister krang finally noticed leo, her smile turning to a sneer. This unlocked something in leo, giant blue portals opening under all the troops, sending them anywhere else while he reached his older brothers mangled corpse.

While he was mourning, krang knocked him away. All he managed to grab was raph's mask as he flew across the battlefield and passed out on impact.

Sadistic as she was, sister krang decided to have fun with him. He woke to his odachi laying broken, just out of reach. While she was slowly breaking his right arm off before tossing it to a hound as a treat, then she started slowly, excruciatingly carving away at his leg, from his hip to his knee, all the way to his femur.

She then grabbed his femur and twisted it out of its socket as slowly as she could, laughing. He managed one more burst of ninpo, teleporting himself, his severed leg, and his odachi out of harms way.

Onto the prosthesis!

Here he is! My favorite middle-aged turtle

What you see here is his uncovered prosthetic since he took off the sleeve for this (more on that later), the majority of his thigh had been too damaged to save from sister krangs little torture session, and instead of just doing something like a rotationplasty and calling it a day

(Image taken from google)

Donnie decided to just remove the damaged tissue and replace it with nanotechnology instead.

Since his femur was left with krang, donnie made him a new one out of some sort of metal as well. It's hollow because why not. but let's talk nanotech, yeah?

I'm not the best at explaining these things (and i only have a surface level understanding of it), but I'll try.

If you've ever watched endgame and watched when Iron Man tapped his chest and his suit built itself on the spot, that's nanotech. Teeny tiny pieces of metal that make something bigger! Or, if you've watched Big Hero 6, it's kinda like the nanobots. The gist is that you just have to program the tech to do what you want. In this case, it's been programmed to act as muscle tissue.

The tech formed individual muscle strands that interlocked with his remaining muscle. That way, it had a pretty straightforward connection. Why make something complex when the body is a perfectly functional mechanism in and of itself?

So, as you might assume with an injury this severe, it took months upon months to heal, even with their impressive healing factor, this is a lot. And to avoid oberwhelming Leo's body and mind too much while he's healing, donnie decided to manually keep the severed leg alive in a machine that simulates the body, providing oxygen and nutrients, and of course, doing physical therapy on a set schedule.

Let me tell you, leo did not like this at all. He was forced to look at the bloody remnants of his leg constantly, always reminded of everything he lost in that last battle for months.

Donnie installed the ports separately and let them heal before reattaching the limb months later. This was especially rough for leo as he had literally lost an arm and a leg and was forced to look at the bloody proof 24/7. When his leg was finally back on his body, he hated it. It felt weird and unnatural at first, but soon enough, he refused to take it off at all.

Present day, he forgets it's a prosthetic half the time, he's just so used to it that it's become part of him, the only time the realisation hits that yes, his leg is gone now, is when he has to do maintenance on it. (lil more on that later, not much, tho)

The prosthetic was designed to function just like an ordinary leg would, and it was a success! It acts just like it did before the injury.

You might be wondering how his reattached leg is still alive, right? Since, y'know, there's nothing but tech connecting it to his body now. Remember how the femur is hollow? There are actually teeny tiny pipes running through the walls of his femur that provide blood to his leg!

At first i thought i could make blood pass through the metal muscle like it would with flesh, but i quickly realised a major flaw in that, were he to, say, get stabbed or something, the muscle would rebuild in moments sure, but there would be blood in the prosthesis and he might get some deadly blood disease from it so-

I decided it would be more practical for it to pass through the femur, since it would take some very severe damage to the prosthetic for it to cause any actual issues, even if he did get stabbed or slashed he would be stunned, but over-all fine when the tech retakes its shape

Now, you might be thinking 'well it can't possibly be removable! It must be permanent' jokes on you. It's completely detachable!

Kinda rushed these drawings, lol, but you get the gist

This whole 'secondary prosthetic' idea is something i actually thought of while drawing these! Since it would be pretty flawed if he was suddenly bedridden or reliant on someone strong enough to carry him if they suddenly needed to escape, lol (my boy weighs like 200+ kg, sure, it's doable, but it's better if he can handle himself in emergencies)

So! His leg can, in fact, be removed! It'll sustain itself for upwards of 12 hours with the built-in mechanism that circulates and provides oxygen and nutrients to the blood in his leg, i won't go into too much detail about that whole process since i already wrote down the gist of it in the picture itself.

What i didn't mention is that the secondary prosthetic is optional, so he can choose to just go legless if he feels like it. He never really went without it in the apocalypse, usually choosing to keep up his everyday work instead of taking a break for once in his miserable life. but now that he's safe and all, he usually just hangs out on the couch or something. Actually, there's some emotions here

When he does take it off, mainly for maintenance, he gets hit with the realisation that he had, in fact, lost most of his leg, followed by depressive episodes where he refuses to leave his room - the couch - or any space he percieves as safe until it's back on. Usually, he ends up moping on the couch bundled up in at least two blankets until his leg is returned to him or, more commonly, he usually does maintenance on it himself, and yes, he mopes the entire time. He will mope for hours on end without saying a single word at times

Donnie, ever the tech enthusiast, invented a whole new fucking metal for this prosthetic, it's specifically made so that normal x-rays pick it up as bone and flesh instead of metal, he also designed a special x-ray that sees the prosthetic as metal, of course. But they usually just used the regular ones just in case something got caught in the tech

Since leo is, well.. leo. He did sometimes store raph's mask in the hollow space in his femur, donnie highly discouraged it but jokes on him. His mask was also stored in there at some point. It wasn't a common occurrence, of course. Just mainly when he wanted to hide them from someone who would have otherwise seen them on the handle of his (very historically inaccurate btw, i did some research), custom nagamaki blade, it's more based on a nagamaki blade than it is an actual nagamaki blade, leo wanted it that way lol

Onto the sleeve!

As you might have noticed, he's missing some skin, right? Not to worry! Donnie designed a protective cover out of a silicon like material. It's like artificial skin!

Showing you his most commonly worn sleeve while standing like the gayest middle-aged turtle you ever did see

When i draw him in colour, his sleeve will most likely be black, as it's my favorite colour on him lol.

His two main ones are black and green, the green one is a bit off in colour, a bit too saturated compared to his scales, it matched his skintone better when he was younger since his scales have dulled with age. And as of right now, none of his sleeves have his markings on them. They're all pretty plain

And as you can see, the sleeve makes his leg look completely normal in shape! You wouldn't even know it's fake if he wore full lenght pants! (Don't tell him i called it a fake leg, he'd smack me lol) anywho, the green sleeve is more discreet if he wants to wear shorts out in public without catching everyones attention, y'know?

He 100% has like three of these just laying around. We all know he's gonna get stabbed, donnie knew, at least

(Sidenote, remember how he lost his arm at the same time? And how raph died? He begged donnie to model his new arm after raph for a very special reason. 'So he and raph could still fight side by side', sappy, i know)

I definitely missed something, and i might add it later if i remember what it is, but here it is! My own prosthetic design

Thank you vv much for reading!

Have nice day

Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precisely at the microscale, in intricate architectures, these ordinary materials can take on extraordinary properties.

With the help of computer simulations, engineers can play with any combination of microstructures to see how certain materials can transform, for instance, into sound-focusing acoustic lenses or lightweight, bulletproof films.

But simulations can only take a design so far. To know for sure whether a metamaterial will stand up to expectation, physically testing them is a must. But there’s been no reliable way to push and pull on metamaterials at the microscale, and to know how they will respond, without contacting and physically damaging the structures in the process.

Now, a new laser-based technique offers a safe and fast solution that could speed up the discovery of promising metamaterials for real-world applications.

The technique, developed by MIT engineers, probes metamaterials with a system of two lasers — one to quickly zap a structure and the other to measure the ways in which it vibrates in response, much like striking a bell with a mallet and recording its reverb. In contrast to a mallet, the lasers make no physical contact. Yet they can produce vibrations throughout a metamaterial’s tiny beams and struts, as if the structure were being physically struck, stretched, or sheared.

The engineers can then use the resulting vibrations to calculate various dynamic properties of the material, such as how it would respond to impacts and how it would absorb or scatter sound. With an ultrafast laser pulse, they can excite and measure hundreds of miniature structures within minutes. The new technique offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials, for the first time.

“We need to find quicker ways of testing, optimizing, and tweaking these materials,” says Carlos Portela, the Brit and Alex d’Arbeloff Career Development Professor in Mechanical Engineering at MIT. “With this approach, we can accelerate the discovery of optimal materials, depending on the properties you want.”

Portela and his colleagues detail their new system, which they’ve named LIRAS (for laser-induced resonant acoustic spectroscopy) in a paper appearing today in Nature. His MIT co-authors include first author Yun Kai, Somayajulu Dhulipala, Rachel Sun, Jet Lem, and Thomas Pezeril, along with Washington DeLima at the U.S. Department of Energy’s Kansas City National Security Campus.

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the Earth drives evaporative processes. Since 2017, researchers have been working to harness the energy potential of evaporation via the hydrovoltaic (HV) effect, which allows electricity to be harvested when fluid is passed over the charged surface of a nanoscale device. Evaporation establishes a continuous flow within nanochannels inside these devices, which act as passive pumping mechanisms. This effect is also seen in the microcapillaries of plants, where water transport occurs thanks to a combination of capillary pressure and natural evaporation.

Harvesting human motion energy: The promise of wearable triboelectric nanogenerators

There is a lot of mechanical energy in human activities, but human activities are low frequency and irregular. As such, traditional electromagnetic power generation mode cannot efficiently collect this energy without affecting the normal activities of the human body. A new energy harvesting method, called triboelectric nanogenerator (TENG), can efficiently collect low-frequency and irregular mechanical energy such as mechanical vibration, sound waves, raindrops, and so on. But there's a catch: Achieving the flexibility, stretchability, and wearability of the TENG is a prerequisite for harvesting energy from the human body. Therefore, the scientists' mission is to make the TENG wearable. Current methods for achieving TENG flexibility and stretchability mostly rely on the properties of the material itself.

The origins of nanotechnology predate Bawendi, Brus and Ekimov’s work on quantum dots – the physicist Richard Feynman speculated on what could be possible through nanoscale engineering as early as 1959, and engineers like Erik Drexler were speculating about the possibilities of atomically precise manufacturing in the the 1980s. However, this year’s trio of Nobel laureates were part of the earliest wave of modern nanotechnology where researchers began putting breakthroughs in material science to practical use. Quantum dots brilliantly fluoresce: They absorb one color of light and reemit it nearly instantaneously as another color. A vial of quantum dots, when illuminated with broad spectrum light, shines with a single vivid color. What makes them special, though, is that their color is determined by how large or small they are. Make them small and you get an intense blue. Make them larger, though still nanoscale, and the color shifts to red.
