I remember hearing a few years ago about a study comparing
publication rates by discipline of the members of the National
Academy of Sciences. I’ve been unable to locate that study,
or anything similar. Does anyone know of such a thing or have
any pointers?

I need to solve an arguement.

I have a pair of thinsulate gloves while my rommate has a pair of
Goretex gloves. Through the course of the winter he repeatedly knocked
me for having "cheap" gloves, until I noticed the little "thinsulate"
tag on the side of one of his gloves. Im wondering what’s the difference
between the two materials. I know that the Goretex gloves cost about
$40 more than my "cheap" thinsulate. Is there some sort of hoax?

Thanks to anyone who could answer.

I was asked by an art teacher what liver of sulfur was. I had never heard of
it. I have discovered it a formed by heating potassium carbonate and sulfur and
is liver colored.

Anyone know what the compound is?

I’ve been working on ZINDO, a semiempirical MO program, but with
its older version. Can anybody tell me how I can get the newest
version of ZINDO? Maybe it’s possible to contact some person who
is working at Prof. Zerner’s labo with e-mail, but I have no
information. Thanks in advance!

How can i start the polymerization of formaldehyde in an 37% aqueous
solution so that i have a good yield of paraformaldehyde ?

What book would be a good introduction to spectroscopy
particularly CD especially if one has a mol. bio.
background?

Thanks.

As a colleague found out:

  In the latest solicitation, they (SBIR) provided a telnet
  address where we can browse the solicitations.  The address
  is iron.nttc.edu (this is at Wheeling Jesuit College and
  their phone is 800-678-6882).  The login is visitor (all
  lower case).  Then, once you provide your email address,
  you can mark any item that interests you by following
  the directions within the menu and it will be mailed to you.

  Help me I am finding the first excited state of caffeine by
spectrophotometry but I can’t find literature values for this.

I am getting  7.3 E-27 or so is this close? What is the correct
  answer?  Does anyone know what I am talking about.  Please
Help me.

Thanks

Fellow chemists,

   A small question.  I am synthesising copper(II) meso-tetra(4-aminophenyl
)porphyrin and I need a good way to seperate it from the uncopperated
porphyrin.  I have tried various techniques with columns (alumina, silicon
gel) and I have tried to filter and recrystalize in may different solvents
(THF, DMF, toluene, CHCl3, EtOH, MeOH, and a couple of others that I can’t
think of right now).  For reference the porphyrin (either) is not soluable
in water, EtOH, or MeOH; it is soluble in DMF, CHCl3, toluene, and THF.

   The other question is: Is it possible that the porphyrins are
polymerizing through the amino groups.  I ahve heard that it can happen
when it(the porph) is placed on an electrode with a current, but can it
happen with olny heat in a reflux.  The two refluxs that have worked for
me are DMF+Cu(OAc)2+porph and the same, but with toluene instead of DMF.
I have also tried a mix of CHCl3 and MeOH and it didn’t react (to
kinetically slow at this temp).

   Any help on either of these questions would be greatly appreciated.
   Thanks.
