                                 number of universities that have

                                    Why is such a program necessary?

   Any college would be delighted
when one faculty member is selected
to receive a National Science
Foundation (NSF) Faculty Early Career
Development Award (CAREER).
However, five members of the PAMS
faculty earned this prestigious honor
this year—and by coincidence, one in
each department.
   “The odds of getting five in a sin-
gle year are pretty low, and receiving
one in each department is amazing,”
said Dean Daniel Solomon. “But it

     A work of fine art?
         Actually, it’s a photograph of
     a new liquid crystalline material
     developed by Dr. James D. Martin
     and his team of undergraduate
     and graduate students in the
     Department of Chemistry.
         Most liquid crystals, like those
     in a digital watch or calculator,
     are based on organic molecules.
     However, at NC State, we have
     developed the ability to control
     the structure of inorganic materi-
     als in the crystalline, glass and
     liquid states.
         This results in the creation of
     new liquid crystalline materials
     with the highest known metal
     content. The high metal content
     is important because it enables us
     to produce materials with unique
     optical, magnetic and electronic
     properties.
         The liquid crystals in this
     image are the circular and fan-
     shaped objects on the black
     background. The photograph is
     entitled, “The Visitors,” by James
     D. Martin.
