Abstract: A non-destructive examination (NDE) system for use on a structural element comprises nano-energetic actuators configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element. The NDE system further comprises sensors configured for measuring the vibrations induced in the surface of the structural element and generating vibration data. An applique comprises a planar substrate, nano-energetic actuators affixed to the planar substrate, each configured for creating controlled combustions in response to thermal energy, and an adhesive affixed to the planar substrate, such that the applique can be adhered to a structural element. A means of transportation having an accumulation of ice comprises a structural element, and nano-energetic actuators, each configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element great enough to generate cracks in the ice.

Abstract: A method of fabricating a part includes stacking sheets of fusible material to form a stack. The method also includes directing a laser beam through at least one sheet of the stack. The method also includes transferring energy from the laser beam to multiple locations on at least one interface between adjacent sheets of the stack, according to a predetermined pattern corresponding with a design of the part, to form corresponding multiple molten regions. The molten regions are conjoined together to form a fused portion of the adjacent sheets. The fused portion of the adjacent sheets defines the part.

Abstract: A Zn—Al layered double hydroxide (LDH) composition is added to a solution including a corrosion inhibitor and stirred, and a precipitate of the solution is collected, washed, and dried to form a corrosion inhibiting material (CIM), in which the LDH composition is intercalated with the corrosion inhibitor. An inorganic CIM and/or an organic CIM may be formed. The organic CIM may be added to a sol-gel composition to form an organic CIM-containing sol-gel composition, and the inorganic CIM may be added to a sol-gel composition to form an inorganic CIM-containing sol-gel composition. Further, the organic CIM-containing sol-gel composition may be applied on a substrate (e.g., an aluminum alloy substrate) to form an organic CIM-containing sol-gel layer and cured by ultraviolet (UV) radiation, the inorganic CIM-containing sol-gel composition may be applied on the substrate to form an inorganic CIM-containing sol-gel layer and cured by UV radiation, and the sol-gel layers may be thermally cured.

Abstract: An example lightning strike protection system of an aircraft includes: (i) a capacitor having a predetermined capacity to hold a predetermined quantity of electric charges provided to the capacitor; (ii) a voltage generating device coupled to the capacitor, where as a quantity of electric charges provided to the capacitor exceeds the predetermined capacity of the capacitor, the voltage generating device converts the electric charge stored in the capacitor into a voltage to generate a lightning leader from the aircraft; and (iii) a conductive path embedded in the aircraft to channel a lightning strike induced by a connection of the lightning leader with an oncoming lightning leader therethrough to be discharged away from the aircraft.

Abstract: A layered tetravalent metal phosphate composition (e.g., a layered zirconium phosphate composition) and a first corrosion inhibitor (e.g., cerium (III), a vanadate, a molybdate, a tungstate, a manganous, a manganate, a permanganate, an aluminate, a phosphonate, a thiazole, a triazole, and/or an imidazole) is dispersed in an aqueous solution and stirred to form a first solution. A precipitate of the first solution is collected and washed to form a first corrosion inhibiting material (CIM), which includes the first corrosion inhibitor intercalated in the layered tetravalent metal phosphate composition. The first CIM is added to a first sol-gel composition to form a first CIM-containing sol-gel composition. The first CIM-containing sol-gel composition is applied on a substrate to form a CIM-containing sol-gel layer, cured by UV radiation, and thermally cured to form a corrosion-resistant coating. One or more additional sol-gel composition may be applied on the substrate.

Abstract: An electrolyte solution for iron-tungsten plating is prepared by dissolving in an aqueous medium a divalent iron salt (e.g., iron (II) sulfate) and an alkali metal citrate (e.g., sodium citrate, potassium citrate, or other alkali metal citrate) to form a first solution, dissolving in the first solution a tungstate salt (e.g., sodium tungstate, potassium tungstate, or other potassium tungstate) to form a second solution, and dissolving in the second solution a citric acid to form the electrolyte solution. An iron-tungsten coating is formed on a substrate using the electrolyte solution by passing a current between a cathode and an anode through the electrolyte solution to deposit iron and tungsten on the substrate.
