  1. Tea contains as much if not more caffeine than coffee
  2. It is already available Wikilink I dont think bioluminescent pait is feasible as the luminescence is a byproduct of a chemical reaction. If you could add the reactants to paint they would not take long to deplete.
  3. Start at the Wikilink then expand your search from there.
  4. National Post Article Seems to be based on hysteria not actual science
  5. I do believe Penn & Teller covered this particular little gem on one of their shows (season 1 Ep 13), they collected several hundred signatures on a banning petition at an environmentalist rally.
  6. Having seen this post on another forum, I say again: Others are much further ahead of you in the development of this as a therapeutic agent and you may be entering a patent minefield. company link
  7. I suspect you will need the strongest acids you can get, HNO3 is available at >90% and HCl at >37%
  8. Ideas re removing silver nitrate stains
  9. An oldie from my High School Days Kipp's Apparatus
  10. a ) phenylmethanal b ) Benzene carboxylic acid, carboxybenzene acid. Dracylic acid c ) Anisole d ) 0-Xylene

    Ethanol from hemp?

    http://www.oilgae.com/energy/sou/ae/re/be/bd/po/hem/hem.html "Hemp plants can produce about half a ton of seeds per Acre but such production is currently relatively expensive. Hemp seeds contain 30% oil, compared to 18% for soybeans, 30% for canola, and 40% for flax. Thus hemp’s Oil content is comparable to that of any other common oil crop. But hemp oil has its problems—the oil degrades even more quickly than other vegetable oils and it is much more expensive than current oil crops. Hemp Biodiesel theoretically can a source of energy. However, it does not appear to offer any significant advantages over other biodiesel sources" Also, here in Canada, there is a huge regulatory aspect. Only certain (Low THC)varieties can be grown, and then only under Govt license, Moving viable seed requires bot shipper and receiver to be licensed. If you are processing it you need a license.
  12. Sometimes Wiki is your friend http://en.wikipedia.org/wiki/Cracking_(chemistry)
  13. http://www.mobitec.de/probes/docs/sections/0201.pdf - Page 2 "The thiol-reactive functional groups are primarily alkylating reagents, including iodoacetamides, maleimides, benzylic halides and bromomethylketones. Arylating reagents such as NBD halides react with thiols or amines by a similar substitution of the aromatic halide. Reaction of any of these functional groups with thiols usually proceeds rapidly at or below room temperature in the physiological pH range (pH 6.5–8.0) to yield chemically stable thioethers." It's not that they don't react below pH 6.5 just probably not very quickly.
  14. If propane were to be broken down into propene (C2H6 to C2H4), is that cracking or dehydrogenation, or both? Its a dehydrogenation. If "cracking" is defined as "the breaking down of large hydrocarbons into smaller ones", then: In the reaction you have listed, which is actually ethane to ethene and not propane to propene (that would be C3H8 to C3H6). You start off with a 2-carbon hydrocarbon and finish with a 2-carbon hydrocarbon which is not "smaller" as it has the same number of carbons. It is the number of carbon atoms which defines the size of the hydrocarbon, not the hydrogens.
  15. Work's really well on Star Trek (or if you borrow H Potter's cloak)
