I am searching for the Standard Gibbs free energy of formation in
water at infinite dilution of the ion of ammonium carbamate (NH2COO-)
at 25°C. I would be grateful for your information (About literature as
well).

Price of copper metal has increased from .75/lb in 2004 to 3.00/lb for 2007 and
is expected to increase in the future. An interesting article from The Austin
American-Statesman newspaper in Texas details the increasing number of copper
thefts across central Texas.

I know that you can use salt to decrease the aqueous solubility of
organic solutes, but does it also affect the partition coefficient?  I
assume that you would promote solubility in the organic phase as you
decrease the solubility in the aqueous phase, but I haven't found this

I think it is possible to mass produce Gold. Using Seaborg's
techniques (particle accelerator) and the new solar energy generators
11Mghz power. The only ongoing material expense would be water and
lead. I suppose there would be more embodied energy in the mining of

There are multitudes of known and commercially used
aliphatic- or aryl-nitro compounds,
say, RH + HNO3 --> R-NO2 + H2O.
Are there also such organic Fluo-Nitrogen analogs,

I am looking into the difference between application of SCADA (HMI) on
Windows or Linux platform.
Can anyone direct me to an article about this?
Are there HMI systems running on Linux?

Watch that and you'll feel pretty stupid. Volcanoes produce more CO2
annully than humans.

Anyone have web links to manufacturers of continuous process
centrifuges (in the USA)?  I'm hoping to centrifuge out polar
compounds from oil.

Awl--
I seem to remember the demo, where H2 was collected over one electrode, and
O2 over the other.
One tube went "pop" with a match, the other lit a burning ember.
