A method of in-situ electrolyte preparation in a flow battery includes providing a vanadium-based electrolyte solution having vanadium ions of predominantly vanadium Vto a first electrode and a second electrode of at least one cell of a flow battery. The vanadium Vat the first electrode is converted to vanadium Vand the vanadium Vat the second electrode is converted to vanadium Vby providing electrical energy to the electrodes. A reducing agent is then provided to the vanadium Vat the second electrode to reduce the Vto vanadium V. The vanadium Vat the first electrode is then converted to vanadium Vand the vanadium Vat the second electrode is then converted to vanadium Vby providing electrical energy to the electrodes. A simple method to produce predominantly vanadium Velectrolyte from a Vsource, such as VO, is also taught.

In-situ electrolyte preparation in flow battery

Disclosed herein is a process for coating a component, comprising applying a bond coat on a substrate of a component; applying a thermal barrier material to the bond coat; and applying a coating containing polynuclear aluminum oxide/hydroxide clusters, to the thermal barrier material. Disclosed herein too is a gas turbine engine component, comprising a superalloy substrate; a bond coat on the substrate; a thermal barrier material on the bond coat; and a coating containing polynuclear aluminum oxide/hydroxide clusters on the thermal barrier material.

A nanocellular single crystal nickel based material is provided having a thermal diffusivity in the range of 0.0002 cm{circumflex over (&#x2003;)}2/s to 0.02 cm{circumflex over (&#x2003;)}2/s and a thermal conductivity in the range of 0.024 W/mK to 9.4 W/mK. The nanocellular single crystal nickel based material may be used to form turbine engine components. The nanocellular single crystal nickel based material may be produced by providing a first solution containing a nickel precursor and deionized water, providing a second solution containing a structure controlling polymer/surfactant and an alcohol, mixing the first and second solutions into a solution containing a reducing agent to form a third solution, and processing the third solution to create the nanocellular single crystal based material.
