GAS-L: Re: Introducing Mike Antal - and Activated charcoal

[Michael Antal <antal@wiliki.eng.hawaii.edu>]

Dear Tom: thanks for your kind words.  I am happy to mail reprints of our
papers to anyone who is interested.  Best regards, Michael.  P.S.  I often
receive requests to post such papers on the web.  This is a very
complicated matter with serious copyright issues (that are well defined by
the ACS in the case of ACS publications).  At least for the time being, I
will only supply hard copies by mail or fax.
