An examination of this video

reveals that the collapse of WTC 7 started at second 17 and completedat
second 23. That is a total of 6 seconds.

Instead of using an equilibrium reaction like 3H2 + N2 <=> 2 NH3 to
heat a boiler maybe there are fast reacting chemicals you could feed to
the intake of what would otherwise be an internal combustion engine.
Eliminate the large heat transfer surface areas of vapor power cycles.

Neutronium is an element consisting of more than one neutron, w/out any
protons or electrons. How do I generate it?

Can anyone recommend a liquid with a low boiling point (Between 35-45
degrees F) that would not be environmentally destructive or dangerous
if spilled into the ground?

Anyone knows anything about this area (Cheminformatics)?

Yes. Nanotech is the cure for almost everything. It can make life
eternal and can keep each and every portion of the brain eternally
active at peak metabolic rate.
GO NANO!!!!!!!

Have a look at the block diagram of a null fluorometer and my question

What I do not understand here is that we are comparing two different

I am having problems passivating several parts manufactured out of 303
Stainless Steel.  The parts are grit blasted and then moved to our
passivation process which has clean, rinse, passivate (Nitric Acid),
rinse, and dry cycles.  We are seeing what appear to be water marks

See the original text.
We use the following special terminology in this article:
{} indicates superscript (including the power).
[] indicates subscript.

I came across the wikipedia article on tetraoxygen (O4) and it
mentioned that at 96 GPa, "oxygen undergoes another phase transition
and becomes metallic."  What exactly does that mean?  If you compress

I'm new here, so this may be a stupid question or in the wrong group,
but can anyone help with the following.....

There is gas in my house and if I don't leave the windows open, I start

this problem?

Sorry about the previous empty post. Stupid ENTER key!!!!!
I am puzzled about something I observed the other day. I took 2g of
CaH2PO4 (0-48-0  fertilizer) and dissolved it in 100g of water. So far,
so good. I expected this to yield CA+ H3O+ and PO4-3 ions in solution.
