Now
Slashdot has this: http://science.slashdot.org/story/09/10/20/2240207 /Element-114-Verified I saw the story and wondered if you had a part in it, Mitch!

Well I've found it, Dowex-50 is used, if anyone was interested. Haha, unfortunetly I plan stick around here, so this may not be last you'll see of me. Hopefully my next topic may go somewhere.

Why are you confused? Most nuclear chemistry reactions use the
conservation of mass-energy not the law of conversation of mass.

I like to think of it in terms of the velocity the reaction progresses through a material. Anything that propagates faster than 1000
Mps probably makes a decent explosive. http://en.wikipedia.org/wiki/Explosive_material#Ve locity_of_detonation

Seems quite simple. What have you got so far.

The GSI claim for element 112 has finally been accepted. Figured once they sorted out the issues with the
decay products of 277 112 (e.g 265 Sg & 261 Rf, it was only a matter of time. No proposed name has been submitted yet. Names based on GSI's location has already been used up (Hassium, Darmstadt). Most likely they will find another scientist to honor. Geiger is still available, but "...

A
free neutron, not proton, is usually used to cause fission. The 235 U atom captures the neutron, forming a highly excited form of 236 U that usually immediately splits (fissions) into 2 smaller atoms and a few neutrons. The 235 U is temporarily (for a fraction of a second) converted to 236 U THEN it fissions.

I suppose Mitch will be much better at answering this question, but my bet would be on coprecipitation - whatever you want to separate is in small quantities, but it will coprecipitate with some other substance - one that can be prepared in much larger quantities and as such will be much easier to oeprate with. That means carrier must be similar enough. But that's just a guess.

I have been interested in Chalk River and all the talk about shutting it down and the the this is the place that produces the worlds largest quantities. But there are
nuclear reactors everywhere in the world and anyone can produce and purify and sell these things, no? http://www.aecl.ca/Science/CRL/NRU/Isotopes.htm
