One can deconstruct the term "SiGNa" to derive Si (symbol for silicon), G (gel), and Na (symbol for sodium, a popular alkali metal). SiGNa chemistry was pioneered by Michael Lefenfeld, a PhD student at Columbia University with the help of Dr. James Dye of Michigan State University. ==References== *Dye, James L., Kevin D.
