Polynitro[60]fullerene has 14 nitros. I wonder if they could add more nitros to it. Or perhaps a few azides.

There are a lot of situations in radiation science where particles that are identical are classified differently based on source. Beta particles are distinct from electrons fired from an accelerator and both are distinct from delta rays which are secondary electrons knocked off by charged particle collisions. They're all free electrons moving at high speeds but they're classified differently due to the source. Same deal for ionized hydrogen versus ejected protons and ionized helium versus alpha particles.

Should there then be a different distinction/classification on the Electromagnetic Spectrum than X-Ray/Gamma Ray for certain frequency ranges? Like, we don't care if radar is coming from a human contraption or the night sky, it's still radar waves.

I think a lot of these distinctions came about before people knew they were the same thing, like how alpha particles were discovered via study of radioisotopes and helium was discovered via spectral analysis of the sun and they were only determined to be the same thing later. Or how delta rays were named during visual observations of cloud chambers before they were known to necessarily be electrons. I don't know the history of x-rays versus gamma rays but I wouldn't be surprised if the distinction was far more solid before high-energy particle physics experiments happened or before weak gamma emitters were discovered. edit: there's actually a lot of stuff in this field that was grandfathered in from early science that never got superseded when new discoveries were made, but no one is in a rush to update things because everyone knows what you mean when you use the terminology or concepts and they're good enough in any case BattleMaster has a new favorite as of 21:04 on Oct 28, 2016 |

Here's something for somebody bored with access to lit databases, or maybe being familiar with off hand considering this thread. Synthesizing buckyballs with things inside seems to have become something of a trend. Has anyone gotten something explodey inside one and exploded it?

There was something upthread about a buckyball of nitrogens instead of carbons if that is sufficient to terrify you?

Yeah beryllium is in the class of materials that have all sorts of useful scientific properties (in this case for use as a neutron shield/moderator/reflector or as a window for x-ray tubes or proportional detector tubes), but are also so nasty to humans that you need a really good reason to justify the use. Lead is kind of in that category but isn't quite as "gently caress you up for life" as beryllium dust is.

I feel like putting something explosive inside a buckyball of nitrogens would probably make it *more* stable, because if there's anything I've learned about chemistry and physics from this thread, it's that the universe is a twisted loving entity.

It's only a danger if you chip the beryllium ceramic insulator on the antenna, but given their nihilistic regard for safety I'm kind of worried for them.

Lead is kind of in that category but isn't quite as "gently caress you up for life" as beryllium dust is. My dad probably got hosed up by beryllium dust, but it was for a good reason.. he made some wheel part for a lunar rover. The tolerances were so tight that he had to pour liquid nitrogen on it to get it out of the die. That shrank the part enough to pull it out, but he only had a few seconds before the mold shrank too and he'd have to wait for the whole thing to warm up and try it again. The next Apollo mission was stressful for him, because if the rover busted a wheel it might be his fault. He was a tool & die maker in the 70s and 80s and I'd planned on posting some of his stories in the OSHA thread. The beryllium probably wasn't even a major culprit.. at the end of every shift he and his co-workers would gather around a big bucket of "methyl" to wash their hands, which I assume was methanol, but might have been something worse. He nearly passed out a few times from methyl ethyl ketone fumes, they used it a lot. He brought home a small jar to use as model glue, it worked great and smelled kinda nice, fruity, and probably gave me some brain damage too. I'd like to see what other stories he has involving alarmingly toxic metals and compounds. In old machine shops, all the fear was directed towards the machines themselves, some of which were still powered by open belt drives, but that's for the OSHA thread.

I seem to recall there are tools made of beryllium (or an alloy?) for use around large magnets... not toxic enough to prefer to lose fingers between your wrench and your experiment I guess.

Every morning when I wake up, I say a quick prayer to the aviation gods to thank them for finally allowing carbon brake disc technology to mature. The Navy planes I worked on back in the early 90s all had beryllium discs. Yeah, no dust hazard there at all! *cough*

Beryllium has to get into your body first to do any harm. Dusts really easy to breathe in but it's going no where stuck in any alloy.

Beryllium copper hammers are non-magnetic and sparkless, so they're used in environments with flammable hazards.

Beryllium copper tools aren’t uncommon. They’re not that bad as long as you know what they are and don’t grind on them. Beryllium oxide insulators are found in a lot of vacuum tubes, by the way, it’s just that microwave ovens contain the only vacuum tubes you’re likely to find in a modern home.

MEK really isn't all that bad for you, the reason it's been phased out is because of limits on VOC emissions as pollutants causing ground-level smog and ozone . In terms of its toxicity, workplace exposure, etc, it's pretty benign.

Beryllium-aluminum alloys are super awesome for motorsports parts as well but are generally not allowed anymore (and are really expensive). I think mostly due to safety issues with manufacturing, but when you blow a beryllium piston out the exhaust pipe it's probably not good for anyone in the area.

I still want to know how the gently caress they still have an intact TGA (a very accurate balance inside a controlled furnace). I would imagine that they have to buy a new one every year at least. Kinetica has a new favorite as of 06:59 on Oct 29, 2016 |

Soviet factories put it seemingly everywhere, like this Nixie tube:  Those strike at 170 V, so I can’t imagine why it would be necessary. You’re probably right about Western consumer electronics, though. I’m going to be honest; those aren’t as interesting.

Golfers are as bad as audiophiles. It’s all about that soft “feel”, apparently. Beryllium is, completely coincidentally I’m sure, the material of choice for high‐end tweeters.
