out on a first date. she asked me "are you artistic?" but i misheard and replied "i've never been diagnosed"

I did a double take when I read "Hydrogen Reduction Reaction (HRR)" for the first time. You mean like Hydrogen Oxidation Reaction (HOR), right? Or Hydrogen Evolution Reaction (HER)?

nope! they reduced molecular hydrogen to hydride!!
jmelville.science
electrochemistry is kickass because it gives us a continuous lever to modulate [electro]chemical potential — something that is normally pinned to discrete & arbitrary reduction potentials in pure thermochemical systems.

in this case, HX and Hye Won quantitate hydricity — so cool!

Congratulations to Hye Won Chung and Dr. Hai-Xu Wang!

Using hydrogen reduction reaction (HRR), where H2 interconverts w/ hydrides, they developed a potentiometric method to quantify molecular hydricity, applied it to substrates including formate & borohydrides, and investigated solvent-dependence.
Reversible Interfacial Hydride Transfer as a Complementary Tool To Measure Molecular Hydricity
Hydride transfer is an essential elementary reaction across the chemical value chain, but there are limited methods available for quantifying thermodynamic hydricity (ΔGH–), particularly among main gr...

i actually know the guy who caused this "small explosion". you are correct to note "many chemistry grad students have accidentally blown something up". you don't want to know how many have intentionally blown something up.

building a reverse film scanner box that uses my camera to take pictures of arbitrary digital images from an external display in order to put deepfaked photos on the blockchain

lol this actually is a use case, every time your camera takes a photo it uploads a statement to a public blockchain that phone ID X took a picture with a hash of Y at timestamp Z, then if you want to use it as evidence you would show that your phone had ID X and the image matched the hash perfectly.

to save you the trouble of googling:

"Seawaymax" is the largest size that can traverse the St Lawrence Seaway connecting the American Great Lakes to the Atlantic Ocean

"Q-max" is the largest LNG carrier that can dock in Qatar

"Neopanamax" ships are bigger bc the Panama Canal got bigger in 2016
jmelville.science
in naval architecture, a "Panamax" cargo ship is one that is designed to the maximum dimensions to traverse the Panama Canal. similar designations exist for the Baltic Øresund ("Baltimax"), Straits of Malacca ("Malaccamax"), etc.

Gen Z maritime engineers may refer to this as e.g. "Suezmaxxing"

1962 is when the efficiency curve of the steam turbine began to flatten out. The entire lifetime of the electricity system had coincided with continuous gains in the design of this technology, and when there weren't more physical gains to be had, the for-profit business model started to crack apart.

too tired to write a concise and unambiguous post in <300 chars but yes I see how it comes off as "ackchually did you know this guy who wrote a poem you like was a nazi"

yes, I agree — my takeaway is less an indictment of Niemoller and more that a popular front against fascism makes strange bedfellows (including avowed former fascists)

lots of dogwhistles here for those with ears to hear them. the one that stuck out to me (and I don't see anyone else mentioning) is Mac Tonight / Moon Man. real old school 4chan white supremacist shit:

[Interior, FBI Crime Lab, Scully & Mulder look over The Grinch's corpse in the autopsy room]

Scully: Odd, his heart appears to have been 3 sizes larger than normal, but there's stretch marks on his aorta, as if it grew suddenly. What could've done this?

Mulder: Not what, who. Cindy Lou Who.

Method 1:

Surviving an Actual Tiger Attack

It's just a bunch of atoms and biochemical reactions...

 Remember that tigers are simply made up of atoms and various biochemical reactions. The tiger's appearance and behavior may be scary, but do not let your fear get the best of you! Decades of research into biology and physics has shown that tigers are actually composed of very small units called atoms, as well as many biochemical reactions such as the Krebs cycle. Things that initially feel scary can often turn out to be harmless upon closer inspection!

If the tiger attempts to eat you, remember that you yourself are simply composed of atoms, and it is simply attempting to rearrange some of them for you

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

graphic designers are fujoshi. "graphic designer" is an oppressive class, like demiromantic people or Floridian people.
