Dr. Feng Li, a Postdoctoral Research Associate at Department of
Chemistry and Advanced Materials Research Institute at University of New
Orleans, gave audiences of Physics Department of UTA a
seminal. The talk is titled "Functional Nanomaterials with
Controlled Structures". The abstract of the seminar is as follows:
Our current research activities are focused on the
chemical-electrochemical fabrication of new classes of materials with an
emphasis on understanding of fundamental issues of nanostructure control
and growth based on templates, self-assemblies and directed assemblies
that will enable the efficient manipulation of material composition,
micro/nano-structure, property and functionality. Such fabricated
materials include nanorings and nanodisks; nanowires (e. g.,
zigzag metal nanowires, porous metal nanowires, core-shell nanowires,
coaxial nanowires and hollow tip nanowires); nanotubules (e. g.,
metal nanotubules, oxide nanotubules, nano-whisker nanotubules and
multi-walled nanotubules); 2-D free-standing nanowires arrays and
nano-networks; 3-D nanosheets, colloid crystal wires and their
peapod-like structures; and metal nanobeads array. Depending on the
design of the nanostructures, the properties of fabricated materials may
be tuned efficiently which leads to their potential applications as
photonic crystals, chemical sensors and data storage media.
