List of ongoing research projects are now
available for graduate students:-
Superoleophobic Surfaces
(27 Feb 2009) 
Disinfection and Catalysis of Ag Nanoparticles
(27
Feb 2009)

of Chemistry, FoS)
Many
surfaces in nature, such as lotus leaves and water strider legs, are
superhydrophobic. Over the past decade, materials with
superhydrophobicity have received a great deal of research interest
in designing self-cleaning surfaces, water-repelling textiles, and
for many other applications. However, superoleophobic surfaces that
repel oils have hardly been studied (perhaps partially due to that
the surface tension of oils is generally much lower than that of
water, making it theoretically difficult to create an
oil-non-wetting surface). This project aims to design and fabricate
superoleophobic surfaces. While the project mainly involves
experimental work on creating superoleophobic surfaces, theoretical
considerations using both the Wenzel and Cassie models are
important. Thus, a student with background in surface science,
polymers, and materials physics is strongly desired.

The use of silver to control putrefaction of liquids and as a
mitigate to the incursion and spread of disease can be traced to
ancient times. In recent decades, studies have revealed the
biochemical reactions of ionic silver that result in the
inactivation of bacteria, fungi, protozoa, spirochetes, viruses,
etc. not protected by proteinaceous membranes. The unique
chemisorption of atomic oxygen on the surface of silver in both
gaseous and aqueous media combined with freedom of movement of
oxygen throughout the crystal lattice of the silver provides a
reservoir of oxygen and thus sets silver apart in its catalytic
activity. However, the broad use of silver as a powerful clinical
tool and cost-effective catalyst is still in the future because its
full range of activity remains to be elucidated. This project aims
to understand the unique antibacterial and catalytic behaviors of
Ag.
