  1. Does anybody know of a good transparent material to store lithium metal under? I need a sample for an element collection. I take apart coin cells for the dollop of lithium on them, and I want to store it so it doesn’t oxidize. I don’t want to waste another coil cell on testing, so could somebody please give some insight on the efficiency of the following materials? They work in theory, but I have not tested them in practice. Also, does anybody know of a good type of oil? And yes, I have tried petroleum jelly (Vaseline).

    -Glycerol 

    -Types of mineral oil?

      Mineral oil seems to be the norm or in argon gas. People who TIG weld use it.

  2. Don’t bother keeping it cold. Just put the oxygen under very high pressure.
  3. If you use pure H2O2, it’s much much much much more dangerous than liquid oxygen or hydrogen. You would probably be better off using just both, and even if you are only using this system to simplify the whole oxidizer/fuel setup to make a rocket more efficient, it’s not going to work. Just like doing algebra a bit differently to get a different answer doesn’t work, this is only causing more trouble than it is fixing. You need just the right ratio of fuel to oxidizer, and the most common problem in early liquid fuel rockets were the fuel mixers. You need to get it going in a perfect proportion, and that proportion is not 1/1 like you would get from splitting H2O2. Besides, the proportion changes throughout the rocket flight for different thrust adjustments. You’re only causing more problems if you want to split it on the spot like in a rocket. And like I said, it’s a much more volatile fuel anyway.
  4. A shame I don’t have a girlfriend, because currently I have to do science stuff alone. It really sucks because I keep seeing pictures of people hanging out and asking each other to dances and I keep thinking “Why didn’t they invite me? How did this new kid that just came here get invited and I didn’t? I barely have any friends, and I can’t seem to get a girl. I don’t really have any male friends, but I’m friends with a lot of girls, but none of them ever want to even consider taking it to the next level. I always feel left out, and I can never fit in.

      Phi for All

      If you always feel left out, you may be looking at everything as a single circle. Life is really about multiple circles of inclusion, and you look for overlapping borders of similarity. It's more like a Venn diagram than some kind of barricaded building, or a dance you aren't invited to. 

      I think the best relationships start with a good understanding of the first level. Sometimes we try to push things to the next level because it's expected, and that's when it can appear insincere or forced. If you already have lots of friends who are women, find even more that overlap with your interests and desires. I think if you work on the first level of any relationship, the next levels have a better chance. 

      Actually, in every story I've heard about great relationships, the people weren't looking for it, it just happened. You never hear someone say, "I really wanted a girlfriend, so I searched and searched and dated a ton of girls, and one of them was Sally and I decided she was the one for me." It's usually more like you spend time with lots of people, but eventually realize that when you have something exciting to share, one person stands out as the first one you call to talk to. A person like that normally starts out as a friend.

  5. Manganese dioxide (MnO2) is a useful catalyst that can break down H2O2 continuously forever (I am conducting in depth research on this reaction, so I have a system that has been running for a very long time now on only a little nugget of MnO2.
  6. Many artists call glaze “liquid glass”, but I can’t quite understand the chemistry that this statement references. Glaze is essentially a liquid mixture of metal oxides, such as silica (silicon dioxide) and, in the 1940’s, uranium oxides.
  7. Well all that I mean is that inside the battery it might be a rather clumsy setup and would be very hard to hook up the contacts without an internal short. If the reaction does do much at all, you would have to have a very clever internal setup. If the battery punctured or suffered even a tiny blow then all hell would break loose and the battery would likely stop working and would be impossible to fix.
  8. Essentially, yes. The human mind is a complex electrochemical balance system that can very easily be shifted simply by your own willpower. If the group puts auxiliary pressure on you to do those good habits it helps as well. All you have to do is say to yourself "Self! I want to be like these people! Lets do this!" It's actually quite a clever and mature way to set a goal for yourself, one that makes you one of the most mature users I have ever encountered before on this site. Hope you got your answer!

  9. I meant that 50% of asteroids with precious metals contain iridium. If you had enough iridium to make 1,000 pounds of it, it would be worth 15.5 million dollars. I phrased it funny sorry.
  10. Asteroids are also unusually rich in iridium, and all of the iridium on earth was deposited by asteroids. A tiny chunk of iridium is incredibly expensive, and since most asteroids that contain metal contain about 50% iridium, imagine a thick 1-ton asteroid made of 1,000 pounds of iridium and 1,000 pounds of other stuff. It would be worth 15.5 million dollars on today's market price.
  11. Hey guys, I tried to perform the hydrogen peroxide splitting reaction that is catalysed by manganese dioxide but I noticed some really unusual results. I had a small beaker with 25 mg of 3%H2O2 and 97%H2O and added 2 1/2g chunks of manganese dioxide I obtained from splitting open a lithium battery. Everything looked fine, and I even got the hydrogen and oxygen gas into an ideal little airtight jar for my element collection. After I obtained sufficient hydrogen and oxygen and made a cool little film of the reaction I left it in a cool ventilated area to prevent the flammable gas mixture from leaking into the house. I must confess I forgot about it for 3 or so hours and when I came back I found the reaction taking place at the same rate, with more hydrogen peroxide splitting around the manganese dioxide every minute without ever appearing to decrease. And now, to bring us to the second oddity I noticed- The 2 separated manganese dioxide chunks were doing an odd sort of dance. They always seemed to be bumping into each other in what appeared to be a very weak positive-negative repulsion. I know the manganese present in MnO2 has ionic properties, but I fail to see why they would both attract rather than repel. What's more, I repeated this in pure H2O and they did not do this at all. Tomorrow I intend to set out the reaction all day to see how long it will last, but until then I would like an explanation to why the reaction catalyst (the MnO2) behaves this way, and why it does this only in this reaction. Does anybody have a theory or answer explaining the phenomena I discovered in my experimental data? Also, if anyone can repeat this reaction finding the same results please let me know your procedures and other data so I can put together a few more pieces of the puzzle. Thanks! -RadioChemist
  12. Hello everybody! I prefer not to reveal my name (nothing personal, just a policy of mine) so I go by Cloud Variable, a nickname given to me by my friends for my understanding of quantum computing and other electronic tomfoolery. I have always been interested in the way things work, and I know a lot about philosophical physics, electroplasmaic engineering (building fusion reactors) and chemistry. I really like the site so far and am looking forward to answering questions and asking a few myself. Sincerely -Cloud Variable (RadioChemist)
  13. I had a similar theory to this which also explains the matter/antimatter asymmetry. I shared it on physics forums, but it got banned by admin because they didn't like theories. I'm not going to post it here, but I definitely think you are on to something, and perhaps we can work together to explain a possible split in the dimensions of our universe. Also, although I am a chemistry know-it-all, I still have a large background knowledge in nuclear and particle physics, as well as a huge knowledge of fusion research and electroplasmaic engineering. -RadioChemist
  14. Hello Andre! The manganese would convert into a black, chunky, powdery, sometimes pastlike oxide known as manganese dioxide (MnO2). The iron would form a red, metallic, flaky oxide which will quickly fall of the metal exposing it to further oxidation. Eventually the iron will all be turned into this iron oxide (rust). The aluminum needn't get that far. It doesn't need water to oxidize, it forms an oxide in air. It forms a very thin and very tough ceramic layering of oxide that is only about one bond thick. It prevents further oxidation so well that you can keep it on the water for billions of years without much of a change. However, pure aluminum oxide is usually a powder. It is a ceramic material with very good heat resistance. To completely oxidize the aluminum, you need to make atom-thick shavings out of the aluminum rod which is essentially impossible. Bottom line: iron would rust away, manganese would convert into a loose chunky black pigment, and the aluminum would go through no visible reaction. Thanks for asking! -RadioChemist
  15. A good electrolyte might be Manganese dioxide, but that is usually used with an ionic fuel such as lithium ions. I think the entire mixture is simply too safe and inert to do much at all. Designing and speculating a more efficient and safe battery is a very noble and fun thing to do, but sadly there is a barrier. A perfectly safe battery would never work. The whole purpose is to be slightly dangerous, and while I commend your work here I think that the reaction would be rather messy and the battery hard to produce. But keep working! Battery technology is improved every day, and you might just be the one to find the right combo of efficiency and safety.
  16. Negative mass just seems really weird to think about. I'm sure quantum mechanics gives it a bit of leverage, but it doesn't seem to be understandable. Yes, quantum theory is really really weird, but you can still basically understand what is going on and why, but negative mass has no sense of logic whatsoever. It just seems so hard to comprehend.
  17. Hydrogen- Thryrotron switch, electrolysis on saltwater Helium- Balloon filling tank Lithium- Battery Beryllium- Old missile gyroscopes (or eBay) Boron- Boric acid, you can easily extract boron from it Carbon- Pencil graphite Nitrogen- liquid nitrogen is commonly available for cooling things Oxygen- Disposable oxygen tanks are commercially available, or use electrolysis to make your own from saltwater Fluorine- Special types of bleach Neon- Neon sign made with ACTUAL NEON Sodium- You can order this through amazon, or you can separate it from salt if you are a particularly skilled chemist Magnesium- Powder is commonly available for burning, solid blocks are available for shaving into ribbons for fire starters Aluminum- Aluminum foil, or solid blocks are commonly available for light weight testers Silicon- Computer chips and laser diode filament Phosphorus- MATCHES!!! Sulfur- 90% sulfur is available in garden centers for fertilizers Chlorine- See Sodium, or make your own from bleach, or if you work in a pool you might have a powder based form of nearly pure chlorine Argon- Wine oxidation preventives. Contact me for more element info
  18. Zinc forms quite a few oxides and hydroxides under these described conditions, and nearly all of them are toxic.
  19. That would be unlikely. Remember, in the ionic bond formed by salt, the sodium gives the chlorine an extra electron, and then they are attracted to each other immediately. If they are disassociated, the electron configurations still remain stable. It would have a filled shell, and therefore be, in a way, a sort of noble gas. But, as it is positively charged, it would still behave like a sort of single atom magnet. But, bottom line, it would barely be volatile at all.
  20. If you do it right, you could possibly use the energetic oxidation of white phosphorus into red form, but it will be extremely dangerous, unreliable, and possibly toxic if broken. The real tricky part is trying to coax the red phosphorus back into white form without spontaneously igniting it. This could work if you only released oxygen into the tube AFTER the conversion is complete, but it would require fancy pumping mechanisms and gas canisters. The fuel would only need to be a bit of power for the pumps, a tube full of phosphorus powder (better to make it red and THEN convert it into white in the chamber), and a few small oxygen canisters. Of course, this is completely hypothetical and a complete waste of time, but I am bringing it to the table. Also, look into the reactions provided by fluorescein. This chemical is extremely easy and hassle free to obtain, and even in it's usual state it produces a green-yellow glow under a UV light. Also research SrAl2O4, (strontium aluminate).
  21. Remember however that uranium content is dropping exponentially , NOT at a linear rate. And the rate of loss does not change because of human interference, we can only decrease the amount of uranium that exists, not the rate at which is does decay. The rate is still an exponential half loss every x amount of years, no matter how much uranium has been taken out. I also happen to be a radiochemist, so i might be able to help with problems that involve radioactive elements and their chemical properties.
