Harry J. Ploehn
ProfessorAssociate Dean for Research and Graduate StudiesResearch in the Ploehn group explores the
relationships among structure, properties, processing, and performance
of materials and processes dominated by phase interfaces, especially in
nanoscopic and colloidal materials. The group specializes in the use of
light scattering techniques and atomic force microscopy for
nanoparticle characterization. Current research projects include (1)
dendrimer-mediated synthesis and characterization of bimetallic
nanoparticles for use in heterogeneous catalysis; (2) characterization
of clays and other platelet materials, as well as platelet exfoliation
in polymer matrix nanocomposites, by dynamic light scattering, AFM, and
electron microscopy; and (3) mathematical modeling of transport
phenomena in electrochemical systems, including batteries, polymer
electrolytes, and supercapacitors. These projects are continually
moving forward toward the goal of developing new chemical and
biomedical applications of nanostructured materials.
