First 3D real-time imaging of hydrogen's effect on stainless steel defects opens the way to a safer hydrogen economy
A study led by University of Oxford and Brookhaven National Laboratory researchers has uncovered how exposure to hydrogen atoms dynamically alters the internal structure of stainless steel. The findings reveal that hydrogen allows internal defects in steel to move in ways not normally possibleāwhich can lead to unexpected failure.
This discovery offers vital insights that could help make hydrogen fuel systems safer and more reliable, from aircraft and fusion reactors to pipelines and storage tanks. The study is published in Advanced Materials.
In a world-first experiment, the team used an advanced X-ray imaging technique to track how tiny defects inside stainless steel (called dislocations) respond to hydrogen exposure. This is crucial to understand how hydrogen can cause metals to weaken or fail, and could guide the design of next-generation alloys for a growing hydrogen economy.

Whumpee clamped a hand over their mouth, stifling the heavy wet breaths that shoved in and out of them in a desperate ache.
They kept their back to the table leg, hoping the monster of a thing tromping around the room wouldnāt see them from this angle.Ā
They shifted minutely as the giant moved, tracking their footsteps and shuffling to the side.
āWhere are you hiding, little pest?ā rumbled the voice. It was so deep. It made sense it would be. Sound reverberates deeper in a larger throat. But. but it was so unnatural, grinding against Whumpeeās little ears.
The monster stopped making sound. Stopped walking. Stopped breathing. Stopped speaking. Whumpee trembled, holding completely still. Their lungs screamed for air they refused to give. They wouldnāt bring it in silently. They couldnāt. Theyād be foun-
They sucked in a gasp of air only to scream it out again as a hand slapped down around the table leg, crushing them against it and shoving the rest of the air from their lungs.
Pain crochet down their spine and one of their legs, immediately turning to a searing wrongness as fingers curled and scrambled around them to trap them in completely. Whumpee managed to wrestle one arm free of the grip before it closed completely, but flailing to try to beat the hand away from them, but it did no good. The giant hoisted them up high regardless, twisting and turning them to look them over.
āAha-! Not as quick as you think you are, huh~?ā
Whumpee squirmed as agony traveled up their femur. āYy-yyyou broke m-ā
āOh nooooo, did I hurt you, little thief~?ā The grip tightened, forcing wheezing air from their chest yet again.
Whumpeeās one arm shoved and battered against a knuckle, but it didnāt give. Not even a bit.
āHow about that, huh? You stopped screaming, so this is probably better, yeah?ā
Whumpee gasped for air, breaths impossibly shallows in their panic and confines. Their head shook back and forth.
āNo? Maybe a little more, then-ā
Something popped. Something popped. Then something else snapped.
Their ribs exploded in pain, crushed under the giantās grip and splintering toward their lungs. Tears streaked hot down their face and neck as they tried to squirm free, but it was useless. Pain ripped through them like a wildfire takes a desolate field of dry grass. Rapid, formless, and all-consuming in its hunger.
āThere we go. That seems like enough.ā Whumper gave them one more squeeze before dropping them down to the ground. āStay out of the cupboards next time, pest.ā
Whumpee wheezed and gasped for breath, trying to shove themself up to hands and knees. Their shoulder gave out, hanging wrong and strange.
āGet out of my kitchen,ā the giant huffed, kicking them half across the floor in a flurry of tumbling hits.
Fear alone made it possible for them to shunt their broken and screaming body to the little crack in the wall, pulling themself inside it and into safety.
Then whumpee collapsed to the dusty floor within the wall, trembling so hard they could feel the bonesā edges grinding together. Their eyes blurred, falling out of focus as they heard the footsteps blessedly retreating to a different part of the house.
Someone would find them.
Someone would come by and find them.
They just had to wait.

Researchers in Purdue University's College of Engineering have developed and validated a patent-pending method that could expand the industrial applications of ceramics by making them more plastically deformable at room temperature.
Plasticity or plastic deformability is a material's ability to be deformed by compression, tension or shear into a specific shape or geometry without breaking. Typically, ceramic materials exhibit very limited plastic deformability under room temperature.
I took a wilderness first aid course in college, and I remember that you can reduce one type of shoulder dislocation in the field, and one you absolutely cannot, but i can't for the life of me remember if it's an anterior or a posterior.
Can you tell me which is which? (at this point I wouldn't try to do it without getting recertified, but it's just frustrating to not remember).
It's anterior.
You can reduce anterior shoulder dislocations in the field because the way that it dislocates means it is less likely that other bones in the shoulder are broken. Meanwhile, with posterior dislocations, its a lot more likely that the clavicle or scapula or the humerus itself is fractured in a way that would make reducing the dislocation dangerous.

sometimes i feel the people in my life donāt see me or care that much.
iāve been constantly flared up, in a heightened state of my baseline, since August, and no one seems that worried or really realizes what that means for me.
my mom and my sibling assume that that means i can continue to do lots of things, and yes, i may flare up, but iāll be okay in the end. they donāt realize that that flare up may last me weeks, instead of just a couple of days.
they donāt really realize that that flare up could make everything worse more permanently again.
iām just waiting for one of these days to go by where i have a really bad flare up like i had in August, and i donāt get better, like how i didnāt get better that time.
and whatās that gonna look like for me?
iāve only improved slightly in some ways since my flare up in August, and thatās just because iāve adjusted to this new level of misery. i continue through, because thatās what i HAVE to do.
but itās just infuriating because they donāt realize that i have to be more careful now. that i SHOULDNāT do these things, as much as i may want to.
at this point, iām just teetering on the edge of not giving two fucks about my health, and doing anything and everything, and mask what happens to me.
i just feel ignored, not seen, not heard. i know they do see it somewhat, they understand somewhat, but also, not entirely.
and i think they donāt realize that i donāt wanna be like this either. if it were my choice, iād be well 24/7. iād go to places, iād have fun the whole time, iād not have to be so self-aware of my body. if i had a choice, i WOULD.
i āhold myself backā a lot, because i donāt wanna end up worse. thatās all. end of story. iām not āholding myself backāāIāM MAKING SURE I DONāT END UP WORSE.
iād like for them to understand that too. to realize just how easy that could be for me. one day, whether i have what i need or not (mobility aids, braces, etc.), i could still get massively flared up, and not get that much better ever again.
i just wanna be seen entirely. heard entirely.
and yes, with the timing of things, it could be the weather; but i donāt think so. i donāt think it is. this was happening before the weather went to shit. and iām pretty damn sure itāll continue through the time that winterās over. i donāt think iām ever gonna bounce back from that flare up in August.
Hello! I loved all the 3 parts of the Leonor fic š can i request one where the reader is the doctor at barca and Gavi gets seriously injured during a match and basically her being very worried about the whole thing?
Omg, I read the request wrong first and wrote a completely different scenarioš
But yeah, I redid it, and here ya go <33
"He's not responding!"
The moment he fell to the ground, I saw my entire world crumble right before my eyes. It wasn't like any fall he, or anyone else here, ever had before. This one was brutal. "Y/N, what are you doing? We need you man!" Enrique, my co-worker shook me vigorously, beads of sweat forming on his forehead as he too realized the severity of the situation.
I instantly snapped myself back to reality, and ran to the middle of the field as fast as I could, pushing past the players who had assembled there, surrounding the whimpering boy who sobbed into the ground, not facing anyone, just clutching his leg that was twisted at an unnatural angle.
"EVERYONE OUTTA THE WAY!" Xavi yells, making more room for me as I kneeled down next to the struggling boy. "I need backup!" I shout, and within a few seconds, other medics joined me too, helping me place the boy on the stretcher. He groans in pain, his face covered with blood due to a nasty cut.
"M-my leg-" He whispers. "It'll be alright." I gulp, freaking out but not showing it. "I promise, everything's gonna be alright." I kick the doors open, and Enrique and Thomas take him to the medical room. "Quick, get the kit." I tell Thomas after helping them place Pablo on the bed. "Help me clean his wounds." Enrique commands, fetching the materials.
I just nod and comply, washing his bloody face gently, but firmly. Pablo hisses in pain, shaking uncontrollably due to the pain and the shock. What happened to him out there was nothing less than pure savagery. "I'm sorry, mi amor. It'll all be over soon." I assure. cleaning his cuts now. Enrique applies some ointments on them, and Pablo screams in pain.
"Hey hey hey, it's okay. Just relax. Breathe!" I panic at the way he reacted. This was bad. So very bad. I give Thomas and Enrique a look, and they instantly realize what it conveyed, and nodded, pinning Pablo down as I sterilized his wounds. By the time I was done treating his face, tears began streaming down my own.
I hated seeing him like this.
He didn't deserve it. None of it! He's too pure to suffer like this, and for what? Scoring a goal? How petty can someone be to just mindlessly attack him like that?! "Pablito, no matter what happens, you hold on now, okay?" I then hold his face gently, staring into his innocent, chocolate brown eyes welled with tears.
He just nods a minute later, calming down a little, trusting me wholly, and unquestioning my actions. I just run my hand through his hair, getting them outta his face, and place a soft his on his forehead to reassure him, before moving on to his twisted leg. One glance and I could tell that it was more than just twisted.
It was dislocated!
"Oh boy-" I wince at the knee, knowing exactly what I had to do. "Y/N? Don't fucking do it." Thomas realizes what was up. "Y/N no way, we're gonna have to call the ambulance now." Enrique backs him up. "We don't have time for that now..." I mumble, knowing exactly how to fix it, but not necessarily being good at it.
I took in a deep breath, and with a rough tug or two, I popped it back in place, earning an ear piercing scream from my suffering boyfriend, tears rolling down his now red face as he squirmed around helplessly. "Hold on!" I cry, spotting another dislocation in his ankle. A minor one this time though. I quickly slid off his shoe, and pinned both his thighs down.
Examining some more, I quickly rushed my hands over to the spot, and with another yank, popped that back in place too. Pablo screams some more, but not as much as before. "It's all good now." I then rush over to him, waving the other two boys off as they decided to leave us alone, and call the ambulance.
Pablo continues wiggling and squirming and crying and shouting, but I just sit down, on the bed, beside him. "Oh Y/N..." He sobs now, burying his face into my thigh, wrapping his arms around my waist, pulling me closer to him. "I am so so sorry this happened to you mi amor..." I wipe my tears, kissing his cheek.
"You have no idea how much it hurts me to see you like this." I sniffle, running my hand through his dark brown, fluffy hair as he continues sobbing in my lap. "Everything's gonna be alright, okay?" I repeat, kissing his cheek again, checking my watch for the time, wondering when the ambulance is gonna reach. "Promise?" He sniffles, in a lotta pain.
