Collaborates with Process Intensification and Innovation Center
at the University of Newcastle in the UK
CAMP is collaborating on nanoparticle precipitation
and coating projects with the Process Intensification and Innovation
Center (PIIC), led by Professor Roshan Jachuck of the Department
of Chemical and Process Engineering at the University of Newcastle
in the United Kingdom.
This Process Intensification and Innovation Center
has pioneered a process for continuous production of nanoparticles
using thin highly sheared films which can be generated on a rotating
surface. Precipitation of barium sulfate has been studied by reacting
barium chloride and sodium sulfate at high supersaturation using
a spinning cone. Excellent micromixing was achieved. It led to very
high crystal nucleation rates, resulting in nanoparticles with tight
size distribution. The spinning cone produces particles roughly
ten times smaller than those made in a conventionally agitated batch
reactor. Potential industrial applications for this process include
pharmaceuticals, paints/pigments, fillers, coatings, CMP, electronics,
the food industry, polymerization, and household products. This
technology is currently being developed and managed by Protensive
distributions of product crystals show that the cone produces
particles roughly ten times smaller than in a conventionally
agitated batch reactor.

Professors Mueller and Markowski Pursue Biomedical Research
Professors Anja Mueller (of Clarkson University's Department of
Chemistry) and Maciej Markowski (of Clarkson University's Physical
Therapy Department) are involved in biomedical research. The objective
of their project entitled "Biochip Olfactory System" is to develop
a bioelectronic device that can detect chemicals with high sensitivity.
One of the most sensitive receptors in nature is the dog's olfactory
system. They plan to take advantage of the sensitvity of these cells
and use them in a biochip device. In addition, they are collaborating
on a coating project for intravascular devices. This involves the
use of hyperbranched polymer coatings to eliminate the need for
anticoagulation therapy. These coatings can be used for mechanical
heart valves, intravascular catheters, vascular prosthesis, and
wires for heart stimulators.
Senior University Professor Richard Partch Offers Short Courses
Senior University Professor Richard Partch offered a number of short
courses. In February of 2001, he taught a three-day short course
on "Bioparticles" in the ERC at the University of Florida. During
the month of March, he gave a short course on "Particle Surface
Modification" at the Particles 2001 Conference in Orlando, Florida.
In addition, Professor Partch served as coorganizer of Symposia
for the Fall 2001 MRS meeting on "Nanoparticulate Materials" and
for the October 2001 conference on "Composites" at Lake Louise in
Calgary, Canada.. He also offered a one-day short course on "Particle
Surface Modification" at the conference in Lake Louise.
