1226 Tailoring Material Properties through DefectEngineering

Harry L. Tuller* and Sean R. Bishopdoi:10.1246/cl.2010.1226

Many advanced materials today derive their function from precise control of point defects. Through manipulation of pointdefects, the electrical, optical, mechanical, and other properties of materials can be systematically modified and optimized. Thisfeature paper illustrates the type of progress that has been made in understanding the often complex equilibria exhibited by manymaterials and shows, by use of examples, how this knowledge can be applied to tailor materials’ properties through defectengineering. Examples which highlight key points of defect engineering include: dark conductivity of radiation detectors,chemomechanics and nanoionics of solid oxide fuel cell materials, sensitivity of high frequency resonators for high-temperaturemass measurements, and emission lifetime and luminescence intensity of phosphor materials.

1251 Lignin Gasification over Charcoal-supportedPalladium and Nickel Bimetal Catalysts inSupercritical Water The mixture of Pd(NH3)4(NO3)2/C and Ni(NO3)2/C is more active for the lignin gasification than

the individual monometal catalysts. EXAFS and XRD show the formation of small Pd−Ni alloy particles, which are the active sites for the lignin gasification.

Band gaps and absorption profiles of water-soluble π-conjugated polymers, which were prepared by the addition−condensation of pyrrole with sodium o-formylbenzenesulfonate, changed with changing their molecular weights and conformations in different solvents. The band gaps were changed from less than 0.19 eV in a solid to 0.59 eV in a solution.

Butanol solution was able to be concentrated to 80 wt % or more from a 1 wt % butanol solution on silicone-rubber-coated silicalite membranes. The butanol concentration process was simplified greatly by the development of this separation membrane. The energy needed to refine the butanol from 1 wt % butanol solution was equal to 13% of the energy of the butanol.

Crystallized thin TiO2 films were successfully prepared via the high-pressure crystallization (HPC) process. Comparing to conventional heating process, the crystallized temperature for thin TiO2 films was significantly decreased. The IPCE values of the crystallized films were significantly increased by the UV-irradiation after the HPC treatment.
