Harry
J. Ploehn
Professor
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.
