SUMMARY:Complex Materials\, Calorimetry\, and Energy Landscapes\, R. G
. Herb Condensed Matter Seminar\, Alexandra Navrotsky\, University of
California - Davis
DESCRIPTION:Freed from the "tyranny of equilibrium"\, modern synthetic
solid state chemists are producing nanomaterials\, metastable phases\
, cluster compounds\, and mixed organic-inorganic materials in a wealt
h of structures with amazing properties. Calorimetric studies have sho
wn that many of these polymorphs or closely related materials are in f
act very similar in energy\, tracing out "energy landscapes" as a func
tion of density\, crystallinity\, hydration\, or other parameters. Thi
s talk focuses on new experimental thermodynamic results in three clas
ses of materials: (1) amorphous and crystalline carbonates in the CaC
O3 - MgCO3 - H2O system\, (2) zeolite
s\, mesoporous silicas\, and metal organic frameworks (MOF)\, and (3)
polynuclear cluster compounds in aluminum and uranium based systems.
