We've already got a molecule that is evidence there is no such thing as a kind and loving god, let's cram some extra oxygens on the ends of it and see what happens One of my favourites from TIWWW is the updates from Klapötke, like the merely (hah) ridiculously explosive C2N14. Yup. Fourteen loving nitrogen atoms in a single molecule, with a couple of carbons acting like nightclub bouncers between two armoured divisions. It explodes if you so much as look at it funny. As in, "The sensitivity of C2N14 is beyond our capabilities of measurement. The smallest possible loadings in shock and friction tests led to explosive decomposition." It explodes if you try to get an infrared spectrum of it. Naturally, as eating a tube of Pringles on the next planet over will cause it to go "boom", its main use is in the field of getting rid of spectrometers you didn't like anyway.

His reverence for the sacred work of Klapötke is endearing. They have to have their labs either underwater or in a hollow volcano, because they're clearly Bond villains.

That's the nitrogen-cage abomination mentioned earlier. http://pipeline.corante.com/archives/2011/11/11/things_i_wont_work_with_hexanitrohexaazaisowurtzitane.php quote:Not that it's what you'd call a perfect compound in that regard - despite a lot of effort, it's still not quite ready to be hauled around in trucks. There's a recent report of a method to make a more stable form of it, by mixing it with TNT. Yes, this is an example of something that becomes less explosive as a one-to-one cocrystal with TNT. Although, as the authors point out, if you heat those crystals up the two components separate out, and you're left with crystals of pure CL-20 soaking in liquid TNT, a situation that will heighten your awareness of the fleeting nature of life.

There are untold numbers of combinations of atoms and then we get into the insane math of their structure and pairing. Once you've put together something you can check and see if it's viable with some math, but marking off all the failures takes a lot of time. It's why protein folding crowdsourcing was popular a few years back, there's just so much stuff that any one thing could not possibly sift through it all with today's tech in any reasonable length of time.

The whole article is a good read, and his metaphors are exceptional as always. That's where "bored silly by something trying to kill you" showed up, at least. http://pipeline.corante.com/archives/2013/05/08/things_i_wont_work_with_dimethylcadmium.php quote:The general rule is, if you're looking for the worst organic derivatives of any metal, you should hop right on down to the methyl compounds. That's where the most choking vapors, the brightest flames, and the most panicked shouts and heartfelt curses are to be found. Methyl organometallics tend to be small, reactive, volatile, and ready to party. quote:If you have a nice wide spill of it, with a lot of surface area, you fool, it'll probably still ignite on its own, giving off plenty of poisonous cadmium oxide smoke. If for some reason it doesn't do that, you will still regret your decision: the compound will react with oxygen anyway and form a crust of dimethyl cadmium peroxide, a poorly characterized compound (go figure) which is a friction-sensitive explosive. I've no idea how you get out of that tight spot; any attempts are likely to suddenly distribute the rest of the dimethylcadmium as a fine mist. e: it was his article on metal azides. http://pipeline.corante.com/archives/2014/06/16/your_metal_azide_worries_are_over.php quote:And before making the metal azide in the first place, naturally, you need to ask "Do I want to blow myself to pieces?" That's because this isn't one of those set-it-and-forget-it Crock-Pot azide reactions.

There is a way to get into the reactor pools to as a job. It involves scuba diving in the reactor vessel itself...where you've got all the normal hazards of diving (faulty air lines, decompression illness, etc), technical diving (underwater welding and working in general doesn't sound terribly appealing, though I hear the pay is decent) on top of the hazards of being near an active nuclear core. My buddy who works in a nuclear plant says these guys get their yearly allowable radiation dose within the first or second job of the year, depending on how long those jobs last and how often they're diving. http://www.popsci.com/science/article/2012-03/swimming-hot-side (Yes, this is a job I would consider applying to, at the nuclear plant not too far from here).

There's at least one, and I assume quite a few, pool-type reactors that are secured by all of a receptionist having to buzz you in. I've been through my university's research reactor building a few times and the main security checkpoint for it is the front desk where you leave your cell phone and pick up a visitor dosimeter badge. Their big security upgrade post-9/11 was to obscure it slightly by removing most of the blatant "Nuclear Reactor" signing and referring to it by a building number or acronym all the time.

To be fair, that's probably a fairly effective security measure for the cost of its implementation. Can't hit it if no one knows it's there.

So, if an actual emergency happens, the firefighters get confused by the maps and everyone will die? Good security. At my university there was, to my knowledge, no research reactor (there used to be a particle accelerator, though). Funny thing was that the doors of the laboratory buildings with real expensive equipment were closed off. You either needed a key, or ring up a receptionist to open the door for you. Or simply use the elevated walkway from a next door building, the doors in those were always unlocked. Carbon dioxide has a new favorite as of 13:42 on Jan 25, 2015 |
