Problem Definition :
Penetration of molten bath and Sodium in  cathodically polarized Carbon samples which are exposed to 
molten cryolite + Aluminum Fluoride + Alumina + Calcium Fluoride,is under investigation.
Molten bath penetrates the carbon matrix through voids and pores after Sodium is 
absorbed in.
It is reason to believe that some compounds such as AlN formed during the penetration process
enhance the wettability of carbon and thus lead to faster penetration and deterioration of carbon.
XPS/ Auger analysis of wall surfaces where frozen salt has filled the voids/pores
can determine whether certain compounds at these surfaces exist.
The samples are cylindrical; Breaking or cutting the samples will result in rough surfaces which
need polishing befire Auger/XPS analysis. However polishing destroys or contaminates the
frozen salt in the pores.
Do you have any experience with samples preparation and analysis by means of XPS
or Auger spectroscopy?

Hi,

I am going to be a new user of autoCAD.
I intend on using the TABLET MENU with a digitizer and a puck.
I have a few questions maybe you could help me.


1) Does the TABLET MENU come with the autoCAD softwear?
   So if I have a digitizer then I can use the TABLET MENU?  True/False?

2) There is such a thing as a template, is it simply a piece of paper
   that I can color photocopy?

3) I have asked around in the computer stores around Spadina and College.
   The prices are $475 for a large digitizer with puck, no template
		  $450 Summasketch II plus 12x12 digitizer, no template
		       with puck
		  $239 9x6 inch digitizer with template.

   How do these prices sound?


All comments and suggestions are greatly appreciated.
I intend on using autoCad to do mechanical drawings.

Is there a 1-800 number I could call about autoCad?  Customer service?

Thank you.

Lab-ware grade Teflon is inert at room temp to almost everything except very

on metal may be "attacked" when the underlying metal is destroyed by the

Teflon is attacked by aromatic radical anions such as naphthalene, biphenyl,

ethers like THF or glyme. A teflon coated stir bar will be turned brown then  
black by this reagent. [probably (CF2)n + e- -> C (amorph) + F- ] I don't know  
about frying-pan Teflon, though the arene radical anion would be killed by air  
unless you did the operation in a glove bag. Liquid NaK alloy also chews up  
Teflon but if you have the skills and equipment to handle NaK, the radical  
anion solutions are probably better.

Isn't the lead PbO2? Will this be reduced to Pb(+2) to form PbI2? (Will other  
oxidants give a false positive by making tri-iodide?) And if the lead based  
paint is between non-lead layers or waterproof enamel, it probably wouldn't  
show up very well. Grinding the chips in mortar & pestle would fix this  
problem, maybe.

As I pointed out in a earlier posting (which may not have made it to the 
net), lead dioxide (PbO2) is available commercially.  Just check the catalogs 
of suppliers like Baker.  It is a *mild* oxidizing agent and without 
significant stability problems (from what I saw).  I guess there's still a 
place for experimental science even though theoretical science is possible.  
Aluminum isn't supposed to be stable in air either, but we are certainly 
using a lot of it.

It is indeed nasty stuff.  I used to make it alot in highschool and it's
a wonder I never lost a limb from it.  It should never be made in large
quantities and never dried on or in anything except a piece of filter
paper.  Depending on the temperature and humidity, it becomes explosive
whenever it likes.  Usually it will become explosive when just a little
of it dries and will send the remaining wet "mud" all around to dry and
become explosive.  In the scores of times I made it, I never found it to
be predictable and once you've made it, it's pretty hard to change your
mind to get rid of it after a very short time.  If you're really bent on
making it, make no more than a gram and make sure you keep any
unsuspecting person away from it until it's exploded, and it will
explode.  It often explodes spontaneously with no help.  If it manages
to dry thoroughly and you want to see how mechanically sensitive it is,
put your goggles on and tape a feather to the end of a broom handle and
touch the feather to it.     Paul (PKJAMES@UKCC.UKY.EDU)

The CFC nitpickingly spoken do not contain hydrogen. Those are the 
HCFC (hydrogenchlorofluorocarbons). They have a much lower ozon depletion
potential, but still are (well may be) hazardous to the environment. The
most environmentfriendly are the HFC (hydrogenfluoro carbons) which do not
contain any chlorine at all, and thus have no ozone depletion potential.

The chlorodifluoromethane (often referred to as R22) is a HCFC, and at
present generally thought to be _the_ replacer for R11 and R12, which 
were used up to now for CFC applications. As R22 still has an ozone
depletion potential of 0.22 (versus 1.00 for R11 and R12) is is considered
to be a temporary solution only.

Let's take the simple approach:  sodium hypochlorite + sulfuric acid.  Both
oxidizers, so we're probably safe in saying sodium sulfate and
hypochlorous acid, HOCl, which would decompose to HClO4, Cl2, and O2.  Then,
you'd have chlorine (toxic) and perchloric acid, which would oxidize the

Hi everybody.
I have a question about Mercuric Oxide.
Therefore I think I must tell you somewhat more about why I wanted to
know something about this chemical.
A few days ago a friend of mine came to me with an unidentified sample.
He said that he got it from a friend and wanted to know what it was.
The only thing he could tell me was that the formula should look something
like SBOHg, but since he is not a chemist he didn't knew what he was talking
about.
I started getting worried since it is strange that someone has a sample of
a chemical of which he doesn't know what it is. Moreover, the friend is from
Zaire. I knew that in Zaire it is forbidden to take mercury (liquid) across
the border because some keen smugglers had found that it was easy to
dissolve gold in it, bring the mercury out of the country, and then destill
the liquid to recover the gold.
Is there anybody who knows to make something out of this misterious SBOHg,
or can give me more info on relations between gold and mercury compounds ?
I don't want other people to miss-use my or other peoples knowledge of
science for underground practices, so please if you can help me, do so.
Thanks in advance.

DeJean.

I can assure you that PbO2 (lead dioxide) does exist at STP.  It is a brown
solid that can be purchased commercially.  I used it extensively in my 
graduate work as a mild oxidizing agent for making hydrazyl radicals from the 
corresponding hydrazides.  It was particularily nice since I could separate 
the solution containing the radical from the oxidant by decanting or 
filtering.

I once got nitrogen triiodide in a 3rd year inoganic unknown prac as

That is just personal preference though. I suggest you use what ever colors
best display the message or information that you are interested in. Perhaps
you would want to use different colors for tertiary nitrogens or C=C bonds
vs C-C bonds.

The information is what is important, not color coordination. (If you doubt
that I have some lecturers for you to see.)

I mean no offense to anyone in the buckyball field with this, but Smalley and 
the guys should wait a few years before collecting the Nobel.  Certainly their 
work in the field is excellent, that I do not doubt, but there are many more 
deserving canidates right now.(Sharpless is my dark-horse vote...).  For all we
know C60 may turn out to be a passing novelty with no true practical 
applications.  But this is just my opinion, maybe they will win, but I would be
suprised.
