well it looks like the video title includes the reaction (NH4)2Cr2O7 + Hg(SCN)2

so

Mercury (II) thiocyanate and Ammonium dichromate


make some Tannerite instead... its legal to posses the components because we're at war with terrorists or something...

The oxidizer is a mixture of 85% 200-mesh ammonium nitrate and 0–15% ammonium perchlorate...the catalyst is a mixture of 90% 600-mesh dark flake aluminium powder, 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydroxide... ammonium nitrate and aluminium powder work too.

thanks to Amazon.com and Google.com, you too can blow up many things.

"Science! Fire! LEARN!!"

oh, half saltpeter and half sugar when lit makes a rockin' smoke bomb....add some oxide of copper to it for some color-fun and cheap!

The most popular "Things I won't work with" article is on this very substance - Sand won't save you this time, and with good reason, it's a good read. The compound itself is described as "much more difficult to handle than fluorine gas" and a stronger oxidizing agent than oxygen itself.

p.s. Oops, should've followed the link in your description first, since the article is linked there already.

What?! When I get a dose of ["can ya turn it up a smidge please"] nitrous oxide at the dentist visit it's really a byproduct of ... cow doo-doo? Say it ain't so

I might be able to *frontpage now... yes bot? (I have many oxidizing chemicals handy if you refuse me again.)

Air! In the Ancient world air was considered one of the elements.

Much later, but before the discovery of Oxygen and oxidation, it was suggested that phlogiston was emitted by burning, and that air had a limited capacity to absorb this substance... so they proposed a situation close to the exact opposite of what we now know to be the case. I think I saw mention of "dephlogistated air" in the video, which would have been air which had extra capacity to absorb phlogiston (because it was pure Oxygen, of course!).

Whats its application?


Many new reactors are experimenting with new fuel types. This has a higher fissile density because of the structure, so you can pack more fuel into a given space, it also has better thermal transfer and less susceptible to radiation damage that traditional uranium oxide. Hyperion Power Generation plans to use a uranium nitride compound in their Gen4 reactor. Gen4 reactors are a whole new breed of reactor, the infusion of modern computer modeling and materials development. While we still have a shitty regulatory system in the US as to not allow newer safer reactors to come online here, they will be launching in places like China, the UAE, and Korea in the future. America is poised to fall behind in the technology it invented, as it has with many other areas that aren't wall street or the technology sector.

It is generally understood that acetaminophen/paracetemol binds and reduces oxidized, 'highly active' COX-2 enzymes... this chills out the COX-2 activity until it is oxidized again and cranks back up. So imagine in this animation acetaminophen kind-of causing that active COX binding site to close up a little for a while, and preventing it from working in that way.

Acetaminophen also doesn't appear to have a lot of anti-inflammatory action near the actual site of inflammation, but rather more globally throughout the body; folks hypothesize a lot about the reason for this, but I like the simple answer that acetaminophen itself can't reduce oxidized COX enzymes in an injured area surrounded by high levels of oxidative species.

But what about paracetamol? That's different, because you can take the allowed dosage of that and the allowed dosage of ibuprofen at the same time without interaction... but how does it work?

Paracetemol is the major painkiller here in Thailand, which annoys me because I believe that I am essentially immune to it. I took paracetemol (tylenol) often when I was in my pre and early teens for migraines. At some point, I found that it just wouldn't do anything for me anymore. Ibuprofen and Aspirin both work great, so I always use those when I have a choice -- but the default is always Paracetemol here.

The actinides are, generally, "safe" to handle, like those Uranium Oxide pellets. You are more likely to damage the pellet with your nasty human oils than the uranium will you...unless you eat the whole thing, but its chemical toxicity will do you more harm that its radioactive toxicity. Uranium oxide just isn't that radioactive, that is why none of the containers or work areas were shielded in this lab.



Now, if they were dealing with a "hot" substance, one that has hard gammas (like when you do MOX fuel recycling), you have to take even greater precautions because then the radioactive problems really do start to show their heads. Not only will it damage your cells faster than they can repair, but it can start to take out unshielded electronics. This is generally only true for fission products, and a few actinides like protactinium which is highly radioactive AND chemically toxic, and generally only man-made (normal occurrences are less than a few parts per trillion in the crust).



These complications are pretty good generalization to why normal LWRs are not the best way to do nuclear, they just generate far to much waste compared to alternatives. You burn less than 1% of the mined uranium in current reactor tech and fuel cycle choices. With a thorium cycle in a molten salt reactor, you can burn greater than 90%, pushing up to 99% or higher if you try real hard. This means you generate an order(s) of magnitude less waste, and that waste generally is safe after about 300 years (radiation is about the same as naturally occurring radiation). There are also other alternates that use uranium in a faster spectrum that perform better than current tech.



A second age of the atom is fast approaching. Unfortunately, those great pioneers which made this industry in the shadow of "the bomb" failed to realize the full potential of e=mc^2. If nuclear power was developed along side the Apollo instead of the Manhattan project, we might already be in that future, alas...it was not to be.



Radiation is fascinating though! I used to believe what I read in the fear news about any radiation leading to death..turns out that isn't so true after all. The planet is a far more radioactive place then you normally consider, and FAR more radioactive when our primordial ancestors evolved. In fact, there are many people living today in what are dubbed High Background Radiation Areas that seem to suffer no ill effect, and some suggest, have lower rates of cancer than other groups. More studies need to be done, but initial findings fly in the face of the notion of radiation I grew up with (that it all is bad and it all kills you!) Some have even suggested that the creator of the entire model used for evaluating radiation risk knowingly lied about it. The entire basis for today's evaluation of radiological risk is evaluated by Muller's findings as supported by the National Academy of Sciences’ of the time. And in fact, might just be based in fear instead of evidence.



Perhaps ancient man went through the same struggles as he tried to adopt fire, some impassioned move against the dangers of fire prevented some groups from using fire and advancing their way of life. Fire, though, allowed the groups that adopted it to improve their life dramatically. The energy released from a fission event is over a million times more energy rich than any energy tech we currently use, imagine what that could mean for mankind. Fusion is over 4 times that of fission (but much harder), and antimatter over 2000x that of fission (and MUCH MUCH harder). Yes, the age of the atom has only just begun, and who knows were man will be a result? Don't settle for solar dandruff, the power of the atom will reign supreme.

This will forever be a discussion between people who work with colours.
In the print industry, the photographic industry or the artists of the world.

The truth is it's different for what ever your process is.
RGB for Light
CMYK for Print
& RYB for artists
I work in all three industries and need to switch my brain back and forth between them constantly.

What they are showing here at the most primary level is the RYB colour wheel that kids learn first. It's basic paints and crayons. These are the base pigments used in paints; Cadmium Yellow & Red, Phthalocyanine (Phthalo) Blue or Cobalt Blue. The closest paint colour to magenta would be a Quinacridone.
The primary colours are the ones all others are made from. These are the ones you can't make by adding something else. We use the chemicals that are the absolute most pure to create these pigmants. They are the highest level of purity and intensity a colour can be. Once you start mixing them, the intensity can only be reduced.
Of course these would be balanced using a titanium white, Iron Oxide Black (plus Umber & Sienna).

As we get older, science class points out that light works differently and is a process that works in subtractive colour. Light being white and the other colours being made by adding filters to block various parts of the spectrum.A blue surface isn't so much blue as it just holds on to all wavelengths of the spectrum but reflects the part of the spectrum that is blue. (Etc.)

In indusry, (and most people still don't under stand this process), the printing process uses Cyan, Magenta, Yellow and Key (Black) (in a transparent or dot)layered fashion to simulate a full colour image.

And don't forget Hexachrome (CMYKOG) which also ads the Orange and Green coloured inks (because simple CMYK cannot simulate every colour).

The CMYK colour system is a simulation of colour and are NOT primary colours. Cyan, Magenta, Yellow and Black are the primary colours within that system only.

ROY G BIV
R Y B are more accurately the Primary Colours in the light and colour spectrum. The coulours between them OG(I)V are all Secondary colours.

*Sidenote: Magenta is an odd coulour which comes from that one man out theory. Indigo is the invisible colour in the spectrum that breaks the rule. That's why in order to create a Cyan colour in paint, we use a Quinacridone pigment. Quinacridone is a transparent colour only and can't be made opaque without mixing it with another pigment and loosing it's purity. It's a damm expensive pigment so it's rarely used.

>> ^robbersdog49:

Primary colours of light are Red Green and Blue.
Primary colours of pigment are Cyan, Magenta, Yellow and Black.
I'm a geeky printer so this bugs the hell out of me. Blue is a mix of Cyan and Magenta, so it's not primary. It's a mix. Red is a mix of Magenta and Yellow.
Maybe they just weren't clever enough to find rhymes for Magenta or Cyan. It's just a shame they had to be wrong.
