An ionic liquid composition comprising a complex of a trihalo aluminum (III) species with at least one organic uncharged ligand comprising a ring structure having at least three ring carbon atoms and at least one ring heteroatom selected from nitrogen and sulfur, wherein the complex is a liquid at a temperature of 100 C. or less. Methods of electroplating aluminum onto a metallic substrate using the above-described ionic liquid composition are also described.

An cicctrodcposited nickel-chromium-aluminum (NiCrAl) composite including nickel- chromium alloy and aluminum, and alloys or compounds formed by Al, Cr and Ni applied on turbine components comprises from 2 to 50 wt % chromium, from 0.1 to 6 wt % aluminum, and a remaining balance of nickel, wherein the NiCrAl composite is heat-treated to form an aluminum compound and to restore materials lost during repair processes of the turbine components.

A nickel-chromium (NiCr) alloy and a method for electrodepositing the NiCr alloy on a turbine engine component for dimensionally restoring the engine component are described. The engine component is restored by rebuilding wall thickness with the NiCr alloy including from 2 to 50 wt % chromium balanced with nickel. The turbine component coated with the NiCr alloy is heat-treated at a high temperature to homogenize composition of the alloy to mimic the base alloy and to restore materials lost during repair of the turbine component.

Systems and methods for generating return journey notifications include obtaining a request for navigational directions to a target destination. An outbound journey route from an initial location to the target destination can be determined, wherein the outbound journey route includes an estimated outbound journey time. A return journey route from the target destination to a return destination can be determined, wherein the return journey route includes an estimated return journey time. The outbound journey route and/or return journey route can be determined at least in part from one or more of current traffic conditions or historical traffic conditions. One or more notifications regarding the return journey route can be generated when comparing the estimated outbound journey time to the estimated return journey time results in a determination that one or more predetermined criteria are met.

Disclosed is a method for activating a surface of metals, such as self-passivated metals, and of metal-oxide dissolution, effected using a fluoroanion-containing composition. Also disclosed is an electrochemical cell utilizing an aluminum-containing anode material and a fluoroanion-containing electrolyte, characterized by high efficiency, low corrosion, and optionally mechanical or electrochemical rechargeability. Also disclosed is a process for fusing (welding, soldering etc.) a self-passivated metal at relatively low temperature and ambient atmosphere, and a method for electrodepositing a metal on a self-passivated metal using metal-oxide source.

Photoactive silicon films may be formed by electrodeposition from a molten salt electrolyte. In an embodiment, SiO.sub.2 is electrochemically reduced in a molten salt bath to deposit silicon on a carbonaceous substrate.

A method of making property modulated composite materials includes depositing a first layer of material having a first microstructure/nanostructure on a substrate followed by depositing a second layer of material having a second microstructure/nanostructure that differs from the first layer. Multiple first and second layers can be deposited to form a composite material that includes a plurality of adjacent first and second layers. By controlling the microstructure/nanostructure of the layers, the material properties of the composite material formed by this method can be tailored for a specific use. The microstructures/nanostructures of the composite materials may be defined by one or more of grain size, grain boundary geometry, crystal orientation, and a defect density.
