Sol-Gel Processed Multilayer Thin Film Design For Solid Oxide Fuel Cell Applications

Sol‐gel silicate thin‐film electronic properties

Organic Thin Film Transistors with Polyvinylpyrrolidone / Nickel Oxide Sol-Gel Derived Nanocomposite Insulator

Polyvinylpyrrolidone  /  Nickel  oxide  (PVP/NiO)  dielectrics  were fabricated  with  sol-gel  method  using  0.2  g  of  PVP  at  different working  temperatures  of  80,  150  and  200  ºC.  Structural  properties and surface morphology of the hybrid films were investigated by X- Ray  diffraction  (XRD)  and  Scanning  Electron Microscope  (SEM) respectively. Energy dispersive X-ray spec...

Thin-film silica sol-gel coatings for neural microelectrodes.

The reactive tissue response of the brain to chronically implanted materials remains a formidable obstacle to stable recording from implanted microelectrodes. One approach to mitigate this response is to apply a bioactive coating in the form of an ultra-porous silica sol-gel, which can be engineered to improve biocompatibility and to enable local drug delivery. The first step in establishing th...

Cerium silicate-based thin-film apatites: high conductivity and solid oxide fuel cell application

We report on the intermediate-temperature synthesis (973 K) and operation (<750 K) of Ce4.67(SiO4)3O-based thin-film oxy-apatites. The apatite thin films show the high conductivity of ∼0.05–0.5 S/cm and excellent stability in reducing atmosphere (<10−17 atm), which makes promising these materials as anodes for intermediate-temperature solid oxide fuel cell (SOFC) application. The proto-type SOF...

Investigation of surface Sr segregation in model thin film solid oxide fuel cell perovskite electrodes

While SOFC perovskite oxide cathodes have been the subject of numerous studies, the critical factors governing their kinetic behavior have remained poorly understood. This has been due to a number of factors including the morphological complexity of the electrode and the electrodeelectrolyte interface as well as the evolution of the surface chemistry with varying operating conditions. In this w...
