Because carboxylic acid salts are water soluble, we can convert water-insoluble carboxylic acids to water-soluble alkali metal or ammonium salts and then extract them into aqueous solution.

Science Can Be Cool

There was no denying it. Professor Johnson was an extremely attractive man. After graduating with his master's degree, he came directly to your school to teach chemistry. While you despised science, you loved to watch your 26-year-old teacher. His shirt was always tight around his chest and biceps and his pants always fit him just right, showing off his ass and a sizable bulge. Whenever he was teaching about titration or the periodic table or whatever, you were never looking at the whiteboard, you were always looking at him.

He was everything you wanted to be in life: smart, attractive, and charismatic. All of the girls (and some of the boys, you included) in your class had a massive crush on him. And who wouldn’t? He was incredible. You wished you could be like him.

It was Friday afternoon and Professor Johnson’s class was your last of the day. You had spent the rest of the day just anticipating another wonderful day of staring at this beautiful man, daydreaming about what he looked like under those tight clothes. After another pleasurable class of ogling and admiration, Professor Johnson explained and assigned a new project due Monday. Everyone in the class had to make an “aqueous solution” and bring it in to present on Monday. Although you spent most of the time staring at his big ass and arms, Professor Johnson was a good teacher, and you had learned that basically, he just wanted you to dissolve something and bring it in. Easy enough!

As you left school, you decided to get the project over with and took a slightly different route to get home, taking you past some of the shops on Main Street. You thought about maybe getting some sugar to dissolve, but that would be too easy and everyone would do it. Maybe you could get some artificial sweetener like Splenda or Equal and talk about how it dissolved differently than regular sugar. That would be creative! Maybe Professor Johnson would think you were smart. Your body shuddered at the thought of him patting you on the back and saying “Good job.”

Splenda it is. Walking down the street, looking at the stores, you paused. There was a sign you didn’t recognize. Aunt Sally’s Mystical Emporium. Glancing at your watch, you saw that you had plenty of time before dinner, so you decided to take a step in. Maybe there was something interesting here you could use for the project. As you opened the door, you heard the chime of the bell above to alert the attendant of your arrival. Glancing around, you saw aisles and aisles of shelves adorned with random objects, bottles, and clothes. Following the velvet carpet, you found the counter, where the woman behind was already staring at you. She was old, probably in her late 80s. She had this strange grin on her face, exposing her yellowed teeth. 

“What can I help you with?” She croaked.

Taken aback slightly at the harshness of her voice, you explained.

“I need something to dissolve in water for a school project. Something really cool.”

Her grin widened, exposing more of her yellow teeth. Without saying a word, she lifted her gaunt hand and motioned for you to follow her. Stepping from behind the counter, she began to move at an alarming pace for a woman her age through the maze of aisles and shelves. Struggling to keep up, you found yourself breaking into a sprint. She stayed composed though. How was she moving so goddamn fast?

Suddenly she stopped. You nearly tripped over yourself trying to stop in time to not trample her. You panted, trying to catch your breath as she slowly reached onto one of the shelves, pulling off a small clear vial of white powder. Holding it out to you, she said “This is magic. It will grant your deepest wish.” 

Oh, so she was insane.

Before you could even open your mouth to say you weren’t interested in some fake powder, the old woman interjected. “I can sense you have a wish in your heart, so for you, it is free.” Her face contorted into that awful grin again. So uncomfortable around this strange woman, you mumbled a thanks, grabbed the vial, and made your way rapidly toward the exit. You felt her gaze follow you until you had pushed open the door, the bell once again chiming, and turned the corner.

Finally, out of sight of the woman, you had a chance to breathe. What the hell was that?! This weird woman gave you some fake powder for free? Overwhelmed, you decided to head home for the night. You would deal with the project later. Once you arrived home, you put the weird vial on your nightstand, took a shower, ate dinner, played some video games, and went to bed. The rest of the weekend, you played some more video games, ate some more, and slept. It was a very relaxing weekend, all things considered.

When you woke up on Monday morning to get ready for school, you had barely put your pants on before you realized that you had forgotten all about the project. Professor Johnson was going to be so angry at you. You couldn't disappoint him. The thought of him shaking his head at you, or god forbid yelling at you... no. You had to figure something out. Scrambling around your room to find something to dissolve in your water bottle, you rediscovered the weird white powder. It was all you had, and honestly, it had a story behind it. Biting the bullet, you headed to the bathroom to fill your water bottle. Pouring the white powder into your bottle, you closed the lid and shook it aggressively, trying to get the powder to dissolve more quickly. As you opened the lid and looked inside, you were astounded. It was clear! The powder dissolved! As you lifted the bottle closer to your face to inspect further, your nose was enraptured by a strange, sweet smell. It was like caramel and flowers and cotton candy and every single fruit all at once. It smelled so good. This powder was incredible. You thought for a moment: maybe it tasted as good as it smelled. You lifted the bottle to your lips, and as soon as the liquid entered your mouth, your chest was filled with a raging pain.

Oh my god, the old crazy woman had poisoned you. Dropping the bottle into the still-running sink, you panicked. Your throat tightened and you couldn’t scream for help. You grabbed your phone, trying to call 911, but your vision blurred. Stumbling blindly, you slipped backward on the mat and landed flat on your back, your phone still in hand, knocking the wind out of you. In shock and still panicking, the pain abated, but the blurriness remained. Taking deep breaths, trying to calm yourself, you slowly lifted yourself off of the ground, clutching your phone, still ready to call 911 for help. You reached around on the counter and finally found a pair of glasses you assumed were your dad’s. Placing them on your face, you were astounded.

In the mirror, looking back at you, was Professor Johnson. The firm pecs, the bulging biceps, the washboard abs. All of it. He was right in front of you. Fuck, he was even hotter underneath those clothes. No longer were you scared, you were aroused. You had wished to become your hot professor, and here you were! Taking out your phone, you took your first (of many) hot selfies in his hot body.

As you took this picture, you saw your dick swelling up in your pants, which stretched with your new thick legs in them. You were always curious about what Professor Johnson was packing. Heading back into your room, you went to your mirror, slowly lowered your pants, and tossed them to the side, exposing your underwear which strained at the pressure coming from within.

Staring at yourself in the mirror, you admired every crevice of your new body. Your feet had grown several sizes pushing your socks to their limit. Your calves had grown and stretched the socks even more. Your thighs were monstrous, covered in veins and leading up to your monstrous dick, which was barely confined within your underwear. Your ass had grown massive and muscular, with the backside of your underpants riding up between your cheeks. Your arms had become enormous: your hands were meaty, your forearms had become covered in thick veins, and your biceps swelled like mountains, barely covering the forest of armpit hair you now had. Your stomach was covered by a thick set of washboard abs, leading up to your pecs which jutted forward from your body like a shelf. You matched your own gaze. Your face was a replica of Professor Johnson’s. You had his manly facial hair and sharp features. You had gotten everything you wished for. You snapped another picture. You were going to love your new body.

Dressing in your loosest clothing, as you now needed a whole new wardrobe, you grabbed your water bottle and left your house, and began the walk to school, ready to show Professor Johnson your aqueous solution and explain how much you loved chemistry.

Cryptography Enthusiasts Requested

As promised, a post about... something. Secret codes!

Several of the blog posts begin with "TRANSMISSION// [something here] // AURORA." The middle section is different in each of these-- one is text in Chinese, another one is Morse Code, and one is what Travis identified as shorthand for elements of the periodic table. I believe all of them probably have some kind of code, but I do not know enough about cryptography to begin with most of them.

Which is where we could use a hand! If anyone has any insight or ideas on any of these (as transcribed below), and would be willing to help us decode them, that would be fantastic!

From January 13, 2013:

TRANSMISSION // 032::3834K::00003 // AURORA

From February 11, 2013:

TRANSMISSION // 0002/02/00002012 // AURORA之動得？違言語？何意味？待・之押that should fix it.

Google Translate says the text here is Chinese (Traditional) and reads, "Can it move? Breaking the rules? What does it mean? Wait and pledge". However, Google translate is obviously not the greatest source, so confirmation or correction would be welcome.

From March 12, 2013:

TRANSMISSION // 052::9JU324::00005 // AURORA

From April 13, 2013:

TRANSMISSION//AURORA//RANDOMGIBBERISHFILTERMALFUNCTION07 RESTARTY/N?

This one seems pretty straightforward, but I'm including it in case others have additional insights.

From May 6 2013:

TRANSMISSION//AURORA//890::E6::FREQ–GK10//–./../…-/.//..-/…//–/—/-././-.–//SEND

The morse code here translates to "give us money".

From June 17 2013:

TRANSMISSION // UUDD::LRLR::BARTN // AURORA

From September 25 2013:

TRANSMISSION // AqPArT::GCaLeV::LiScSaCa // AURORA

Travis translated the elements here as: AqPArT: Aq: aqueous solution is a solution in which the solvent is water, Phosphorous, Argon, Titanium

GCaLeV: Gallium, Calcium, Lanthanum, Vanadium

LiScSaCa: Lithium, Scandium, Samarium, Calcium

For reasons I lack the chemistry knowledge to understand, he took these as numbers, or dates, and translated it as such: X/31205723/3216220.

So that what we've got so far! Thoughts?

[metastablephysicist]

in 1944 don mastick broke a vial containing 10 mg of Pu in solution. it is estimated that 10 μg Pu ended up on his face and in his mouth. there was a post floating around claiming that plutonium has a sweet and sour taste, but reliable sources say he tasted acid, and/or they say tasted something metallic. he probably just tasted the dilute acid (probably aqueous hydrochloric acid, which tastes like vomit) and the metallic taste is probably from the radiation (it occurs in radiation therapy patients receiving doses near the face). but i was curious if there was enough plutonium chloride for him to taste it. taste is based on molecules, and since this wasn't elemental plutonium, we don't know what just plutonium would've tasted like. but as for PuCl3:

according to the DOE archives the solution was "sealed in a glass vial several inches long and about a quarter inch in diameter" which i'll interpret as ~2.5 mL. i'm gonna say we had a half-full vial, but we don't really know. if that volume is on the mark, that means the concentration of plutonium was 0.0334728 mol/L. for a full vial, 0.0167364 mol/L.

from a quick internet search, the lowest measured taste threshold (bitter tastes, specifically quinine) is at 0.0000015432 mol/L. for sweet tastes, specifically sucrose, it was 0.01462 mol/L.

so yeah, okay, it's possible he did taste it!

post in question under the cut:

the other details aren't quite right either—he worked in a different lab after the war; his breath wasn't forever radioactive (but his urine was for 30 years). but whatever.

rantaro has you for pre - dinner coming from that kaito and rantaro pregame smut request! this is the rantaro one. <D kaito one is in the making!

cw: ns/fw content, publicity, eating out, f! parts, cursing

a/n: gotta love that pre - game rantaro smut. Instead of giving my own definition cause I’m dumb I went on Google for the scientific words. yeah

“Aw, come on. You’ve been so stressed lately. I think it’s time you let me help you unwind a bit.”

Those words were a foreshadow of something that started a very, very bad idea. At least, to most people.

You covered your mouth while you continued writing. You felt his tongue flick up as a response.

Rantaro was - no sugarcoating it - eating you out during your last period class. He was under your desk, which the model was one that could obscure him from everyone else in the busied class.

He attacked your nerves again, his mouth slowly wrapping around your bud as he used his hands to good use - fingering you at a teasingly slow pace. Fuck, it was almost too much.

You could vaguely hear the professor saying, “What is produced at the anode in electrolysis of aqueous solution? I should see everyone knowing this.”

Fuck, fuck, fuck.

You shakily raised your hand to match everyone else’s aloft ones, praying that he wouldn’t call on you.

“Shuichi, tell me the answer.” The professor gestured to the dark haired figure to answer.

You breathed out a small sigh of relief, quickly retrieving your hand from the air. You gripped at the side of the desk.

Rantaro, meanwhile after you’d shot your hand down to hold onto the wooden table, sped up his movements to more sensual, passionate gestures. Your legs shivered. You were unbearably close.

You could practically feel his lustful expression as he devoured you piece by piece, the thought almost making you groan out while the professor continued his lecture.

Sensing that you were just dancing over the edge, Rantaro slowed down and pulled back away from your sex - a string of saliva mixed with your own essence connecting him with it.

You kicked him lightly in return as if to say, “Don’t you dare stop. Fucking continue.” He stifled a laugh as a response.

As you kicked him in the arm, this time harder, he dove back into you.

Your face was crazily hot, which made you glad that it was just as hot outside. Then maybe you could use that as an excuse, given that the air conditioning in the classroom wasn’t exactly the best.

You whimpered quietly at your seat, one of the only sounds you’ve made during the session.

You felt his tongue lick around your bud before he took out his fingers from your hole and replaced it with the tender muscle. He felt so perfect to you.

You felt your climax approaching, sweat running down your temple. You wrapped your thighs around his head, squeezing him closer to you. He merely smirked and continued at this.

“Y/n. Tell me what is the difference between electrolysis of molten and aqueous solution.” You heard the professor echo out, making you shoot your head up to look at him. Fuck.

You sighed quietly as you felt your face heat up more. Your mind was a complete mess as of now. Still … “It’s …” you faltered, “E - Electrolysis of aqueous solution g - gives chlorine gas at anode and hydrogen gas a - at cathode. Electrolysis of molten sodium chloride yields chlorine gas at anode but liquid sodium mm - metal at cathode!” You slurred and smooshed your words together, somewhat comprehensible.

“ … Good.” Your professor simply raised an eyebrow, before looking somewhere else in the room to continue. “Now … ”

You zoned out again, looking down at Rantaro. You kicked him in the thigh for speeding up while you were talking. He ‘innocently’ smiled back up at you. Or, as innocent as you can get when you’re busy eating out your lover.

Fuckfuckfuck! You were so close!

The feeling of his tongue inside your walls made your head spin. It’s like he knew all your sweet spots, those spots that’d almost make you mewl on the spot.

You pushed him even closer to you, making sure that he couldn’t pull back and escape. He ravaged hungrily like nothing short of a monster, his tongue lapping at your wetness as the edge approached quickly.

You gripped onto his hair, almost suffocating him in the plush of your skin.

After one last thrust of his tongue, you came into his awaiting mouth; his tongue gratefully licking up all of your juices spilling into his throat. You coughed into your elbow to cover up a lewd moan, the sight being so erotic seeing his eyes inhabited by mischievous glints.

Nothing got on the ground, nothing to accuse the two of you of what had just happened. You slouched back on your chair, Rantaro moving back after he’d swallowed everything; making a show of it by opening his mouth to you and sticking his tongue out.

Fuck, he looked so perfect …!

“That’s it. Class dismissed. Test tomorrow.” The professor clapped his hands as a horde of students went to exit the room, you being slow to stand.

You took your chance to let Rantaro out from under the desk when the professor left to go settle a small scuffle in the halls, his smirking grin never leaving his face.

“I’ll get my payment back at my dorm, yeah?”

Precise chemical doping of organic semiconductors in an aqueous solution

A research team consisting of NIMS, the University of Tokyo and the Tokyo University of Science has developed the world's first technique capable of precisely doping an organic semiconductor in an aqueous solution without requiring a vacuum or a nitrogen atmosphere using special equipment. This technique—which uses water, previously unexploited for this purpose—could bring about a breakthrough or even a paradigm shift. The study is published in the journal Nature. Chemical doping is a crucial process in semiconductor device production. Doping organic semiconductors involves the use of redox agents. Because effective redox agents are prone to react with water and/or oxygen, they need to be handled in a vacuum or a nitrogen atmosphere created using special equipment. In addition, these doping methods do not allow precise, consistent adjustment of doping levels.
