- SiGNa chemistry
SiGNa chemistry is a type of
chemistry in whichalkali metals are encapsulated into porous oxides ofsilica gel in order to reduce their pyrrophoric and highly combustible properties while preserving the desirable reduction reactivity of the metals (Dye, et al). 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
