Now we need to figure out how and why
You're missing the part where you try over and over again to replicate the result and it keep failing. Looks like the first time was the only time, too bad. Then, as you clean out the freezer six months later, you find a leftover vial from the experiment in the back that randomly formed perfect single crystals that you excitedly diffract only to be disappointed because despite everything it's somehow triphenylphosphine oxide because it's always triphenylphosphine oxide. Even though there was supposedly no phosphorus of any kind in the original experiment. Turns out, the undergrad intern has been double-dipping pipettes in your special personal cache of NaK-dried THF and cross-contaminated it, and that contaminant TPP stabilized your experiment---phosphine stabilization is well known, after all, which is why you were trying something new and different without phosphine to begin with. Oh well, sucks to be you, the undergrad graduated already and is gone.
My vigour returned and in truth I thrived, and to think I take up sugar now! Banting and co shared a Nobel Prize and their work saved north'ard of a million lives, Nobel them all!
I was lost to cruel disease when a miracle cure saved mother her son. Dried her tears, now I'm a croakin' man but I'll never more fear the last of Banting's imparted years!
I don't know much about this, but I can't help but think that "complete" and "consistent" are doing a lot more work in that sentence than my current understanding of the terms would lead me to believe.
I resent that. Here in the good ol' US of A we have severe disdain for ki- wait goddammit.
THIS COMMENT SECTION IS NOW PROPERTY OF THE FEDERAL REPUBLIC OF wait
and get rid of my one kitchen crutch? absolutely not
For those who did a search only to get back pages of less-than-useless SEO slop that just recites the number line, here is something that better describes some of the grammatical insanity.
also, czterydzieści cztery is imo one of the less pronounceable words (well, two of them) in Polish.
Sure, there may be a maximal element, but not necessarily a maximum (there might be multiple people of equal and maximal gayness, not just one person).
Also, not relevent to the logic here per se, but last time this went around the conclusion was that a spectrum implies a total order, not just partial.
Yes, on the rare occasion I cook meat. Too unpracticed otherwise. I originally got one because I'm colorblind and was scared of undercooking red meat and tired of eating leather. As a bonus, I used it to get the temperature right when I got into fancier teas and inadvertently trained myself to judge the temperature of water pouring into my mug by the sound it makes within a couple °C, which is kinda neat. Now, if I could figure out how to do something similar so I stop overcooking food, that'd be grand...
I know that this is partially a joke, but I was trying to figure out what kind of lab would be done to produce chloroform that would be appropriate for students (recent OSHA crackdown on chloromethanes notwithstanding)... haloform reaction I suppose? Is that a common teaching lab experiment?
My mom took my little brother to participate in a child psych study like this when he was a toddler (mom had some ties to the university). It was a very similar experiment with skittles as the prize. My brother sat staring glumly at the candy the whole time. The test administrator was increasingly enthusastic with praise after each round right up until the end when she congratulated him and said that he could have the whole bag. He said "no thanks" and ran back to mom crying because he was told there would be candy but they only had skittles, which he very much did not like (and for that matter still doesn't). The administrator was apparently embarrassed and told my mom that she thought that all kids liked skittles....

I realize (and you mentioned) that sugar is not a well defined term, but calling degradation products of ethanol in gas "sugars" is still a bit of a stretch. Ethanol by itself usually forms some combination of acetaldehyde, acetic acid, 2-carbon peroxides, and CO2 (i.e. not sugars) upon autoxidation, though those species can react with other components of gasoline to form the precipitated "gum". The structure of gum in the literature is pretty hand-wavy (high MW materials kinda just be like that sometimes) but tends to be much more more oxygen-deficient than conventional "sugars" (polysaccharides) even for ethanol blends and contains a wider variety of substructures. Though, I have seen some papers talking about certain microbes that can ferment the ethanol in gasoline, possibly via sugars, but I don't think that's the common degradarion pathway for a mower.
According to my buddy who worked for Dow, part of these "savings" apparently was taking a hatchet to their R&D segment with a bunch of spray-and-pray layoffs (apparently a common happening these days). I realize Dow is mostly commodity chemicals these days which is much more preservative in nature than other segments of the chemical industry, but even so it sounds like they are killing any hope of competing with new technologies and moving to the "squeeze as much as possible out before it goes tits up" stage.
On the other hand having a manager willing to yell at/stonewall the MBAs when they deliberately lie about misinterpret your recommendations and timelines is a godsend.
Rent. Probably could buy if I got my shit together, but I'm skeptical that my employer won't go down the toilet in the next few years with the "pricing pressures" and the fact that they just laid off like 60% of their non-preservative R&D staff.
A bunch of electrons? Nah F only ever wants just one more than its natural allotment. But it is extremely, violently jealous of that electron.
Off during the day and between 17 and 20 °C when sleeping depending on the season.
Apparently this particular catalyst is pitched as an H2 evolution catalyst by oxidizing alcohols... can anyone with access to the article tell me where that energy comes from (thermo- or electrocatalytic)? IIRC alcohol dehydrogenation is endothermic by like 15-20 kcal/mol. A 1->2 reaction has an entropy change of ~30 eu, so quick math and dirty looks from p-chemists gives an operating temperature somewhere around 300 °C. That's quite a bit better than conventional crackers but still requires significant thermal encouragement...
