A reverse configuration, lithium thin film battery ( ) having a buried lithium anode layer ( ) and process for making the same. The present invention is formed from a precursor composite structure ( ) made by depositing electrolyte layer ( ) onto substrate ( ), followed by sequential depositions of cathode layer ( ) and current collector ( ) on the electrolyte layer. The precursor is subjected to an activation step, wherein a buried lithium anode layer ( ) is formed via electroplating a lithium anode layer at the interface of substrate ( ) and electrolyte film ( ). The electroplating is accomplished by applying a current between anode current collector ( ) and cathode current collector ( ).

One nanostructured actuator embodiment includes an actuation region between electrical contacts. The actuation region includes an elastic matrix with embedded nanocomposite layered structures, which have inorganic material layers with pillared organic material structures between the inorganic material layers responsive to the surface acidity of the inorganic material layers. The elastic matrix allows transport of species for changing the surface acidity. A separator region is between the electrical contacts. A proton generation region capable of reversible electrochemical production and elimination of protons is provided, which may be a hydrogen storage material located on a side of the separator region opposite the actuation region, which may include metal hydride, or metal hydroxide. Alternatively, it may include an electrolytic solution and conductive particles within the elastic matrix for in situ electrochemical generation of an acid/base. The conductive particles may include carbon nanotubes, metal fibers, and/or metal nanoparticles.

In one embodiment, a solid state actuator is provided having a solid state lithium storage material and a solid state volume changing material having a metal capable of changing volume in response to lithium insertion and removal. A solid state lithium ion transport material is located between the lithium storage material and the volume changing material. A pair of electrodes are connected so as to be capable of providing an actuation voltage across the lithium storage material and the volume changing material. In some embodiments, the volume changing material has active material particles comprised of metal contained in an inactive matrix. The active material particles may be aligned so that when the active material particles expand the volume changing material expands substantially in one direction. In some embodiments the volume changing material is a metal alloy and the lithium transport material is a high stiffness material. In some embodiments, multiple actuators are stacked, interleaved, or pillared.

Photo-oxidation catalysts and methods for cleaning a metal-based catalyst are disclosed. An exemplary catalyst system implementing a photo-oxidation catalyst may comprise a metal-based catalyst, and a photo-oxidation catalyst for cleaning the metal-based catalyst in the presence of light. The exposure to light enables the photo-oxidation catalyst to substantially oxidize absorbed contaminants and reduce accumulation of the contaminants on the metal-based catalyst. Applications are also disclosed.
