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
 O<sub>3</sub> - MgCO<sub>3</sub> - H<sub>2</sub>O system\, (2) zeolite
 s\, mesoporous silicas\, and metal organic frameworks (MOF)\, and (3) 
 polynuclear cluster compounds in aluminum and uranium based systems.
