The Sigmund Group focuses on interdisciplinary development, synthesis, and characterization of novel materials. Particular interest is placed on developing materials that can benefit mankind including: improving the environment, increasing energy efficiency, and improving health.

1. Investigation of Surface Forces

Surface forces for materials from micron to nanometer size including nanomaterials, such as carbon nanotubes, ceramic nanoscale and micron sized particles in collaboration with the Particle Engineering Research Center.

See the surface forces section for further information.

2. Nanomaterial Synthesis

Synthesis techniques include: electrospinning, sol-gel processing, gel combustion, chemical vapor deposition. This research is conducted in collaboration with Dr. Nino and Dr. Marijnissen.

3. Processing

Processing of submicron and nanoscale particles based on principles developed from the understanding of the powder/liquid interface and surface forces including: temperature induced forming, joining of ceramics, colloidal processing, slip, tape, and direct casting.

See the processing section for further information.

4. Nanoparticle Research

  1. Nanoparticle based solid state sensors for combustion engines in collaboration with US-DOE High Temperature Electrochemistry Center.

  2. Electrode materials with catalytic function in low temperature solid oxide fuel cells,
    in collaboration with US-DOE High Temperature Electrochemistry Center.

  3. Smart particles in the purification of drinking water and remediation of flue gas from power plants in collaboration with Drs. Wu and Mazyck, Environmental Engineering, EPA, and NASA.

  4. Multifunctional particles with advanced photocatalytic properties for homeland security in collaboration with the Particle Engineering Research Center.

  5. Enhancement of signal to noise ratio in biomedical and cell functions in medical applications in collaboration with the Juvenile Diabetes Research Foundation Gene Therapy Center.

  6. Investigation into toxicity and medical uses of nanoparticles in collaboration with the Center for Research at the Bio/Nano Interface.

  7. Plastron effect for clean surfaces in collaboration with Dr. Spatz, Max Planck institute für Metallforschung, Stuttgart, Germany.
