I’ve been asked to set up a demo of an oscillating reaction to "wow" some
visiting high school students.  I’d appreciate it if anyone out there can
pass on a reference to a staight-forward method.  Thanks in advance.

We have an HP1090M hplc setup with a diode array detector running from a
prehistoric Pascal based data acquisition and analysis software package.  I
know that I can replace my ancient HP216S computer with a PC clone and plug
in an HP-IB interface card.  The question is: am I locked into having to
purchase the data acquisition card and software (>$4,000 from HP excluding
the computer!).  One of their engineers tells  me that no other options are
available for *controlling* the chromatograph.  I dislike the idea of being
locked into an expensive one-vendor situation.  Any solutions or ideas will
be appreciated in either e-mail or posted form.  Thanks!

To whom it may concern:
        I am in need of a database (ftp preferred or gopher) that can be used to download
Material Safety Data Sheets.  I have found only a few and they are usually quite limited in
number of compounds available.  If you have any information please post to this newsgroup or
send and email message to tbr…@students.wisc.edu

Thanks in advance for any advice you may have,

> What’s wrong with Carbon-12?

  There are no coincidences in a superdeterministic universe. Carbon
atomic number is 6 and in math the number 6 is absolutely perfect since
1+2+3=6 and 1x2x3=6 and -1+-2+-3=-6 and -1x-2x-3=-6. And organic
chemistry is primarily the study of carbon compounds which form the
basis for life. All is interrelated, interconnected.

   I have a problem on understanding the complex number used almost everywhere
in physical chemistry. For example,

   refractive index = n + ik

   What is the phsical meaning of the imaginary part?
   Could someone answer my question?

   Thanks in advance.

We observe that acid has an affinity for glass.  We hear tales of
people getting acid burns or being disinterated with acid, such
as an old superman series where a criminal tried to use the Statute of
Limitations law to avoid prosecution by sealing himself in a concrete
chamber that could only be breached by the application of an acid.

I am guessing that bases (hydroxides) are much more caustic than acid.
We know of many ways that people expose themselves to acid without
harm.  People drink lemonade and enjoy it immensely.  Can you get Real
Lemon on your skin without harm?  People are known to have highly
acidic stomachs without melting down.

I propose that perhaps acid becomes caustic in glass because the stray
hydrogen ions are absorbed by the glass, leaving more caustic
chemicals in solution.  -David-

Hi everybody!

        This may be a FAQ, but I would like to know if somebody has
the new (February-March 1994) forms for submission of grant proposals
to NSF. We got a while ago some for MS-Word (for Mac), and if some
like these are avialable, could you please give that info? I’ll really
appreciate it. And yes, I looked into STIS, but could only get the
PostScript files, what we would like is something more "friendly"
than having to edit .ps files.

        Thanks in advance for any help/info/pointer/suggestion you
could give. If possible please answer to my e-mail address:
                cstgn…@acfcluster.nyu.edu
because I read the news once a week usually. I will summarize the
info in a future posting.

        Greetings.

I have been asked to monitor buckyballs in the air in one of our research
labs.  Does anyone have experience in sizing the clusters (I will be using a
Coulter Multisizer and gentle sonification to remove the material from a
filter), or know much about their pulmonary toxicity?  I think some of the
balls may be doped, which would have to change their chemistry somewhat.  I
have not seen anything published in this area.

        I’m doing a report on the chemical formaldehyde. What a need more
information on though is the manufacturing process that is used in
industry for it. (the gas, formalin, paraformaldehyde etc…) Could anyone
help me out here or point me somewhere? Thanks.

I am looking for a process/procedure for producing a hard anodize coat on
 titanium, niobium and zirconium sheet metal. The anodize layer must be
a strong dielectric to prevent electrical shorting in an electrochemical
cell.

This request is for a co-worker, but please send any responses via e-mail
to me at HSD…@UTRC.UTC.COM.  Your help is greatly appreciated.
