Summary of Activities/Interests
The interests of our research group lie in the connections between the synthesis, processing and structure of materials and their performance. In particular, directed research programs in corrosion inhibition of aluminum alloys has lead to a family of environmentally benign corrosion inhibitors that self-catalyze protective film growth and significantly improve corrosion resistance. Electrochemical methods are used to fabricate ordered templates with nano-meter sized features directly on silicon wafers for use in the fabrication of sensitive IR detectors and selective bacterial sensors. Other electrochemical studies of pulsed plated and photochemically produced catalysts and carbon nano-tube coated gas diffusion layers have yielded very effective PEM fuel cell electrodes.

Nanotechnologies for the Life Sciences, Wiley-VCH, 8:208-238, 2007. This chapter describes a quick method for bacteria detection using a gold
nanowire based biosensor and electrochemical impedance measurements. Detection methods have been developed with the use of gold nanowire (GNW) substrates attached to a C11 linker arm in turn attached to the specific E. coli antibodies . Preliminary results indicate that the GNW biosensor can detect as few as 50 E. coli cells with a sensor area of 0.178 cm2. Although this report gives the initial results for
this novel procedure it can be used in wider applications. The specificity of detection
of any cell depends on the availability of a specific antibody directed to the cell surface macromolecules or antigens . This method would be applicable to
detect any cancer cells based on the antigens present on cell surfaces, such as
human colon and breast cancer cells containing LeX and Sialo-LeX . Antibodies
against these antigens are available commercially.
Juan Jiang, Timotlhy Hall, Loukas Tsagalas, Davide A. Hill, Albert E. Miller. Photographic production of metal nano-particles for fuel cell electrodes. Journal of Power Sources, In Press, xx:xx-xxx, 2006. A photographic Pt printing process has been used to prepare catalysts for fuel cell applications. Ferric oxalate was used as a UV sensitizer, absorbing UV energy and converting Fe3+ to Fe2+, which then reduces metal catalyst ions, such as Pt or Pd ions to metals in the presence of a developer, such as ammonium citrate. Transmission electron microscope (TEM) and scanning electron microscope (SEM) studies revealed that Pt particles smaller than 5 nm were formed, however, the particles tended to aggregate and form clusters up to 300 nm. A deposition efficiency of 16% was obtained when Pt was printed on Nafion membranes. The catalytic performance of the photo-printed Pt was evaluated using a single H2 fuel
cell. The mass-specific electrochemical area of the catalyst, H2 crossover rate through the Pt-printed membrane and the membrane resistance were measured. At 60 •C, a peak power density of 75mWcm-2 was obtained with a MEA consisting of photo-printed Pt (0.12 mg cm-2) on a Nafion membrane as the catalyst. Cyclic voltammetry measurements in solutions containing methanol or formic acid showed that a mass-specific methanol oxidation current of 197mAmg-1 Pt could be achieved and that the co-deposition of Pd with Pt lowered the formic acid oxidation potential in
addition to reducing the formation of the "poisonous" intermediate COads.
