Harry J. Ploehn

Professor and Graduate Director


Research 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.
