Biographical
Sketch:
James
H. Adair is Director of Penn State’s Particulate
Materials Center and a Professor in Materials Science
and Engineering. His research and teaching interests
include biological-nanoscale particulates and phenomena,
colloid and interfacial chemistry, material chemistry,
particle characterization, and ceramic and metal powder
processing. Included among his activities is Director
of the NSF Industrial/University Cooperative Research
Center on Ceramic and Composite Materials organized
in collaboration with Rutgers and the University of
New Mexico.
Dr. Adair is the author or co-author of over 175 publications,
seven patents, and several copyrights on computer software.
He has been chair or co-chair of multiple symposia related
to materials chemistry and colloid and powder processing
science at American Ceramic Society and American Chemical
Society meetings. He is also the co-editor of nine books
including the Handbook of Characterization Techniques
for the Solid-Solution Interface. |

Areas
of research:
Underpinning our research
are the concepts and principles embedded in colloidal
and interfacial chemistry. Our
objectives in student education at both the undergraduate
and graduate level is to integrate a fundamental understanding
of materials science with colloid and interfacial chemistry. There
are currently two research thrusts in the Particulate Materials
Center, both with an aim toward nanomedical applications. The
underlying science for both technologies resides in our
currently unique ability to colloidally manipulate and process
nanoscale (sub-50nm) particulates for drug/bioimaging applications
and producing bulk nanograin materials and devices with
focus toward reducing the scale of surgical instruments
to the sub-100 micron regime. To put the latter effort
in perspective, a conventional heart biopsy instrument
via catheterization has a scale of 5mm. The drug
delivery systems consist of bioresorbable calcium phosphate,
nanoporous silica or titania, or calcium phosphosilicate
particulates into which medically active substances including
drugs, genetic material, peptides, proteins, and fluorescent
molecules have been captured. The 2 to 50 nm particulates
have been suspended in suspension up to 20 weight percent
with resistance to aggregation obtained for up to 36 months. We
are utilizing the colloidal understanding of the nanocomposite
particles for applications ranging from the delivery of
medically active agents to the fabrication of nanograin
components and devices. Typical grain sizes produced in
our zirconia ceramics are 50 70 nanometers while some of
the nanograin metals have grain sizes at the 20 to 40nm
scale. Thus, our research directed toward nanocolloids
is yielding benefits across a broad spectrum of medical
applications. |
