Putting a new spin on 1T phase tantalum disulfide: Scientists uncover a hidden electronic state

Research often unfolds as a multistage process. The solution to one question can spark several more, inspiring scientists to reach further and look at the larger problem from several different perspectives. Such projects can often be the catalyst for collaborations that leverage the expertise and capabilities of different teams and institutions as they grow. For half a century, scientists have delved into the mysteries of 1T phase tantalum disulfide (1T-TaS2), an inorganic layered material with some intriguing quantum properties, like superconductivity and charge density waves (CDW). To unlock the complex structure and behavior of this material, researchers from the Jozef Stefan Institute in Slovenia and Université Paris-Saclay in France reached out to experts utilizing the Pair Distribution Function (PDF) beamline at the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Brookhaven National Laboratory, to learn more about the material's structure.

Pollution Powers AU Fiddleford manifests his power while he's out working in the fields on the farm. He walks into the house and is immediately told to go shower, because he reeks and is filthy. Which is expected after working the fields.

But when he's done showering, Ma McGucket scolds him for not washing properly. He still smells and has dirt on him! Fiddleford is confused, given he scrubbed like usual. But he goes to shower again.

When he emerges, his skin is rubbed raw from how hard he was scrubbing, but he still smells, and as Ma McGucket watches, patches of dirt form on his freshly washed face.

And she realizes that something strange and possibly serious is going on.

#Fidds' odor isn't dismissed as just ''teen boy in puberty'' bc it is a v different smell from that #no he smells like shit. like literal shit. #sometimes he smells a bit different #like ammonia or hydrogen sulfide #but mostly he smells like animal poop #eventually he's able to tone down the odor as I've said before #but when his power first shows up it is VERY overwhelming #Pollution Powers AU #speecher speaks #(I just realized I posted a Fiddle centric post on Fiddleford Friday #I did it!

Doodledex - #705-A Hisuian Sliggoo

While there's no outward change to the Goomy that lived in Hisui, the same can't be said for their evolution! Thanks to exposure to high concentrations of iron in the water there, Hisuian Sliggoo are Steel/Dragon types and have developed a large, round, metallic shell! (And yeah, this technically makes them snails instead of slugs.)

However, unlike normal snails that only keep their organs in their shell, Hisuian Sliggoo holes its entire body up in there, with only its head and arms sticking out! It seems like this would make it awkward to move around... but when it needs to go fast it will retract all the way into its shell, stand itself up on its side and roll away!

#pokemon #doodledex #sliggoo #hisuian sliggoo #while iron kinda exists in the bodies of most organisms #(vertebrates especially: it's what makes our blood red!) #an iron shell isn't actually all that strange! #the scaly-foot gastropod is a kind of deep sea snail that really does have iron in its shell! #(and as its name implies in the scales on its foot as well!) #these guys live around hydrothermal vents... which also happens to be where they get their iron! #well more specifically they wind up releasing iron sulfides released by the special bacteria in their bodies that help them process the uh. #vent soup? as the scales and the outer layer of their shell. because apparently snails usually can't handle sulfur all that well #but thanks to this the snail doesn't die of sulfur poisoning AND gets armor out of it! #(one of these iron sulfites is pyrite! there are snails with fool's gold in their bodies and that's pretty darn neat!)

is there an age where wine is supposed to taste good. i'm in my early 20's and i can't get past the rotting fruit taste enough to drink it

So the way i learned to like it was trying a wine class in college when i was twenty something, cause I wanted to learn to drink it for gallery openings. It taught me how to drink it properly and notice how much it changes according to what you pair it with or how warm/cold it was, and after that first tasting I pretty much got to a point where even drinking it quickly i could notice a lot more of the flavors then i did before, and it became a really exciting and interesting thing! And for me personally, I found that more sugary wines tasted much less pleasant to me than drier wines.

Like yeah, drinking it with something and doing the little swirl and scenting it really does change how it might taste to you!! And once that happens you really do start noticing stuff like “hey this tastes like crisp pears if you removed the sugar!!”

Also don’t buy the cheap stuff at walmart, that actually does taste like paint thinner (but you don’t have to get the most expensive either! Usually a twenty dollar bottle from you local liquor store is going to be pretty tasty.)

And like i suppose warning, i generally like stuff that actually tastes like what it is. Like the sugary cocktails that are essentially a milkshake or slushie with a dash of vodka tastes like cough syrup to me. So my pallet might be more geared to it.

#my favorite cocktails are the gimlet #the french 75 #and the ramos gin fizz #all amazing very citrusy cocktails #but yeaj genuinely you do kinda have to learn how to #but onceyou do you really can taste it #anon #answers #also i can drink it much any more cause i react to the sulfides rip #wine

Nucleophilic substitution is one of the most important reactions of haloalkanes and can lead to a wide variety of new functional groups, several of which are illustrated in table 18.1.

Note the following points from table 8.1.

While the symbol Nu:- is used to represent any nucleophile, not all nucleophiles are negatively charged.

If the nucleophile is negatively charged, as for OH- and RS-, the atom donating the pair of electrons in the substitution reaction becomes neutral in the product.

If the nucleophile is uncharged, as for NH3 and CH3OH, the atom donating the pair of electrons in the substitution reaction becomes positively charged in the product. Often, the product then undergoes a second step involving proton transfer to yield a neutral substitution product.

I AM SO CURIOUS ANT YOUR TAGS ON THAT POST. Permafrost clothes smelling like rotting mammoth??? What do you DO for a living???

I'm a geologist! Still in school at the moment, but for one of my classes we've gone to the Permafrost Tunnel. I'm pretty sure there's only the one, but for Reasons I won't say specifically where it is tho it's not too hard to find if you look it up. A lot of field geology ends up getting pretty smelly, but the Permafrost Tunnel in particular is notably Foul and messy because the permafrost is made of loess, which is very very fine and gets everywhere. And since there's also a lot of organics in there, and since its thawing a little bit just from human body heat from activity in the tunnels, the organics are rotting, so it Stinks.

If you ever have the chance to visit, absolutely wear a mask, or you will be blowing loess-filled snot out of your nose for hours.

#hopefully what ill do for a living is work at a mine. which is ALSO smelly. but for other reasons #the mill STINKSSSSS. sulfides and arsenic baybeeeeee

fucking hell, fact-checking ANYTHING on the history channel is fucking wild.

bermuda triangle theory involving the sargasso sea bc of sargassum seaweed: claims it gets caught in propellers & rudders, claims it then grows on the ship, claims that it then rots in massive clumps that lets off hydrogen sulfide which can apparently trigger depressive symptoms and/or psychosis. their evidence is 1 guy who went sailing around the world but lied abt it & hid in the atlantic ocean before documenting his mental decline before apparently falling overboard on accident or on purpose.

fact checking?

sargassum seaweed is a misnomer, it's a macroalgae. apparently the sea (in the atlantic ocean) is notable for its beautiful blue water that are super calm--the sargassum grows bc the currents & streams circle around the sea, creating perfect conditions.

it is a non-issue for boats & sailors. it's not a threat.

it doesn't rot en masse, most likely. it's mostly a problem if/when it washes ashore on the beach, THEN it releases some hydrogen sulfide which IS toxic. but in open air on the water or on a beach? you gotta be hanging around huffing it to suffer anything besides system irritation.

this would be supported by the fact that sargassum supports MULTIPLE lifeforms BREEDING HABITS, including eels (remember that whole thing? THAT is true lol) & loggerhead turtles.

finally, the guy who lied in the round the world sailing comp? he stayed off the coast of south america, not in/around the sargasso sea.

he suffered a mental break that was clearly from 9 months of isolation and lying, facing the consequences of that lying, etc. he had planned to just finish last, hoping they wouldn't scrutinize his logs. then 2/4 other guys bailed out of the race, one of whom only fucked up his boat by pushing it too hard bc he thought the lying guy was ahead of him.

when he disappeared on july 1, he was still near south america, i'm p sure.

so all the PIECES of their claim are technically true, except for the seaweed causing boating issues.

but together? total fabrication.

perfect reminder to FACT CHECK EVERYTHING. including (especially) bullshit on the history channel 🙄

#me listening to the theory: oh wow that's interesting! the proof of hydrogen sulfide seemed light j should double check it #me reading everything afterwards: jfc 🙄😒

Team develops transistors with sliding ferroelectricity based on polarity-switchable molybdenum disulfide

Over the past few years, engineers have been trying to devise alternative hardware designs that would allow a single device to both perform computations and store data. These emerging electronics, known as computing-in-memory devices, could have numerous advantages, including faster speeds and enhanced data analysis capabilities. To store data safely and retain a low power consumption, these devices should be based on ferroelectric materials with advantageous properties and that can be scaled down in terms of thickness. Two-dimensional (2D) semiconductors that exhibit a property known as sliding ferroelectricity have been found to be promising candidates for realizing computing-in-memory, yet attaining the necessary switchable electric polarization in these materials can prove difficult. Researchers at National Taiwan Normal University, Taiwan Semiconductor Research Institute, National Yang Ming Chiao Tung University and National Cheng Kung University recently devised an effective strategy to achieve a switchable electric polarization in molybdenum disulfide (MoS2). Using this method, outlined in a Nature Electronics paper, they ultimately developed new promising ferroelectric transistors for computing-in-memory applications.
