RESEARCH
Stay Updated
Regents Professor Alexandra Navrotsky's research interests have centered on relating microscopic features of structure and bonding to macroscopic thermodynamic behavior in minerals, ceramics, and other complex materials. She has made significant contributions to mineralogy/geochemistry and solid-state chemistry/materials science in the fields of ceramics, mantle mineralogy, deep earth geophysics, melt and glass science, nanomaterials, and porous materials. She has developed unique high-temperature calorimetric techniques and instruments and her laboratory the Peter A. Rock Thermochemistry Laboratory, collaborates with scientists worldwide.
RESEARCH INTERESTS
NUCLEAR ENERGY MATERIALS
Understanding the thermostability of the materials in
nuclear reactors, including molten salt reactors.
Safe disposal of nuclear materials to decrease
harm to the environment.
ENERGY MATERIALS
Energy materials have a wide range of
applications such as fuel cells, batteries, and
water splitting. Understanding their
thermodynamics is needed to improve
performance under operating conditions and reduce
decomposition and other unwanted reactions.
ZEOLITES
Zeolites are aluminosilicates that can
be used as catalysts for a variety of
organic chemical reactions, with
current uses in several catalytic and
sieving applications.
MATERIAL STABILITY ON PLANETS
Material stability on Earth and other planets
constrains their formation and evolution and has
environmental ramifications to understand
mineral decomposition and dissolution that
may release nutrients like iron or
contaminants like nickel.
HYBRID MATERIALS
Organic/inorganic compounds such
as hybrid perovskites and metal
organic frameworks (MOFs) which
contain large organic cations or
linkers have various technological
applications.
