IN MEMORY OF DR. GABRIEL ENRIQUE ASTURIAS-SOBERANIS

The group recognizes the contributions of Dr. Gabriel Asturias in the polyaniline area. He obtained his Ph.D. from the University of Pennsylvania under the guidance of the late Professor Alan G. MacDiarmid. Unfortunately, he passed away prematurely in 1996 before his work could get proper recognition.

Gabriel Asturias showed for the first time that aniline could be polymerized in the presence of polymeric acids, like polystyrenesulfonic acid or polyvinylsulfonic acid to yield water soluble doped polyaniline that remains conducting even at high pH. Collaborative research with Professor Howard Reiss showed that this was related to Donnan equilibria. This very important work (often forgotten) was published in 1991. See also J. Chem. Phys., 98(3), 1 1993 (see ref 1,2). Several groups have expanded on this concept of using polymeric dopants in conducting polymers.

Gabriel was a friend and colleague of Dr. Manohar. They were fellow graduate students in 1987-1992.
