Laboratory for Extreme and Energy materials (LEEM) is focused on developing fundamental processing-structure-property relationships in materials for extreme environments and energy applications. The primary interest is to uncover the microstructural phenomena occurring at different length and time scales through sophisticated measurements, and understand how those mechanisms can be utilized to dictate material design and performance.

Research Interests:

  • Spark plasma sintering (SPS) of structural and functional ceramics.
  • High-strain rate (dynamic) deformation of advanced materials.
  • Micro-mechanisms of deformation and failure in extreme environments.
  • Microstructural characterization and structure-property relationships.
  • Time-resolved diffraction measurements of lead-free piezoelectric ceramics.

Materials of Interests:

  • Advanced nanoceramics and composites for high-temperature aerospace components, impact protection and lightweight structures.
  • Lightweight cellular solids for automotive bumpers, personal protective gears, kinetic energy absorption and shockwave mitigation.
  • Dielectric, piezoelectric and ferroelectric materials for actuators, capacitors, sensors, sonar, ultrasounds, and energy harvesting.

Facilities:

  • Material processing facilities
  • Split-Hopkinson pressure bar (SHPB)
  • Dynamic indentation hardness tester (DIHT)
