Systems and methods for the treatment of materials with an alkali metal such as lithium for the manufacturing of batteries and capacitors. In one illustrative embodiment, a liquid lithium composition may be formed by dissolving metallic lithium in a solution that includes a suitable organic agent, a suitable solvent and suitable film forming agent. Each component of the solution may be present in an effective amount to perform its desired function. The lithium may be dissolved into the solution to obtain a lithium to organic agent molar ratio of from 1:1 to 10:1. The liquid lithium composition may then be dispensed onto a suitable substrate material and allowed to remain thereon for a suitable time for a prelithiation reaction to proceed, followed by drying. Dispensing may be performed by spraying the liquid lithium composition and drying may be performed at a relatively low temperature and a reduced pressure.

This disclosure relates to a method for obtaining superhydrophobic corrosion-resistant coatings. State-of-the-art approaches involve etching methods with elevated temperatures and/or longer duration which are complex and use high concentration of combination of acids, alkali, and salt solutions in etching process to obtain a roughness which makes it difficult to handle usage of chemicals and controlling process. The method of the present disclosure has addressed this issue by selection of optimum concentrations of combinations of one or more type of acids, oxidizing agents which are safe, easy to handle and provide better control over the process. The method of the present disclosure is easy, inexpensive, and environmentally friendly. The superhydrophobic corrosion-resistant coatings possess water contact angles greater than 151° and coating efficiency more than 85 percent arrived at by using corrosion currents from polarization studies.

A method of forming an implant to be implanted into living bone is disclosed. The method includes the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further includes forming a nanoscale roughened surface on the microscale roughened surface. The method further includes the act of depositing discrete nanoparticles on the nanoscale roughened surface though a one-step process of exposing the roughened surface to a solution including the nanoparticles. The nanoparticles have a material having a property that promotes osseointegration.
