Atomic Layer Deposition of Undoped TiO2 Exhibiting p-Type Conductivity. The catalytic performance was measured using as little as 1 cycle of Pt ALD, which corresponded to a surface mass loading of 10 ng/cm(2). This observation is consistent with the formation of oxide ion vacancies on the oxide surface.

However, generally only a small fraction of solar energy absorbed by photosynthetic organisms is converted to a form of energy that can be readily exploited. The calculations attribute the catalytic activity changes primarily to changes in the workfunction and secondarily to the d-band structure of supported Pt particles.

Proton Transport Membranes for Fuel Cells: Polymeric versus Dense Ceramic". We attribute the superior cell performance to significant reduction in both the ohmic and the polarization losses due to the combined effects of employing an ultrathin film electrolyte, enhancement of effective area by 3-D architecture, and superior catalytic activity by the ceria-based interlayer at the cathode. The flame reduction method has unique advantages of a high temperature (>1000 C), ultrafast heating rate, tunable reduction environment, and open-atmosphere operation, so it enables rapid formation of oxygen vacancies (less than one minute) without damaging the nanowire morphology and crystallinity and is even applicable to various metal oxides. These cells have great promise for many clinical applications, including that of regenerative medicine. Bai, S., Fabian, T., Prinz, F. B., Fasching, R. J. Previous studies of osteogenic potential in ASCs have focused on chemicals, growth factors, and mechanical stimuli. It took five years of experimentation to find it, Singh said, and five more to .

Comparison of the experiments to the simulated results identified that the variation of micro-geometry influenced also the volume-dependent degradation rate and induced the osmotic pressure. Electron energy loss spectroscopy measurements with scanning TEM indicated increased oxide-ion vacancy concentration at the grain boundary core. A fabricated nanotubular SOFC theoretically attains a 20-fold increase in the effective surface, while projections indicate the possibility of achieving up to 40-fold.

Atomic Layer Deposition (ALD) Co-Deposited Pt-Ru Binary and Pt Skin Catalysts for Concentrated Methanol Oxidation. The addition of the 1 nm film led to an increase of the maximum power density of a low-temperature solid oxide fuel cell (LT-SOFC) by a factor of 1.50 at 400 degrees C. The enhanced performance can be attributed to an increased oxide ion incorporation rate on the surface of the modified electrolyte. Sample scaffolds were constructed for purposes such as channel-directed cell growth and size-based cell sorting. However, existing doping methods face the challenge of simultaneous control over the morphology, crystallinity, dopant distribution and concentration at the nanometer scale.
