摘要: Embodiments of nanostructures comprising metal oxide and methods for forming the nanostructure on surfaces are disclosed. In certain embodiments, the nanostructures can be formed on a substrate made of a nickel titanium alloy, resulting in a nanostructure containing both titanium oxide and nickel oxide. The nanostructure can include a lattice layer disposed on top of a nanotube layer. The distal surface of the lattice layer can have a titanium oxide to nickel oxide ratio of greater than 10:1, or about 17:1, resulting in a nanostructure that promotes human endothelial cell migration and proliferation at the interface between the lattice layer and human cells or tissue. The nanostructure may be formed on the outer surface of an implantable medical device, such a stent or an orthopedic implant (e.g. knee implant, bone screw, or bone staple).

摘要: A discrete metallic particle having a metallic material, and a coating covering at least a portion of the metallic component. The discrete metallic particle has a thickness from 50 nm to 1000 nm, and the discrete metallic particle has a skin depth δ of greater than or equal to 1.0 μm in a frequency range from 20-40 GHz. The skin depth δ is calculated by: δ = 2 ρ ( 2 π f ) ( μ 0 μ r ) ≈ 503 ρ μ r f Where δ is skin depth in meters (m); ρ is resistivity in ohm meter (Ω·m); f is frequency of an electromagnetic radiation in hertz (Hz); μ0 is permeability; and μr is relative permeability of the metallic material.

摘要: Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

摘要: A method of increasing corrosion resistance without leveraging toxic hexavalent chromium uses partially oxidized graphene particles mixed into primer applied on metallic alloy surfaces. Graphene is effective as an anti-corrosion primer additive because it acts as a physical barrier and has electrochemical properties that change potentials needed to induce corrosion.

摘要: The invention relates to a method and system for preventing corrosion of at least one metallic structure in an electrolyte medium, comprising applying a superimposed time-varying frequency electromagnetic wave to the structure, the method comprising the steps of generating a superimposed time-varying frequency electromagnetic wave (DAC wave) where an AC driving signal with time-varying frequency is riding on a DC output with a predefined DC bias voltage, transmitting the DAC wave current to one or more emitters, emitting the DAC wave via the one or more emitters, placing the one or more emitters at a spaced distance from the metallic structure, subjecting the metallic structure to the DAC wave current, controlling the negative return current of the DAC wave from the metallic structure, such that the DAC wave is distributed across the structure surface and directly excites a target region of the metallic structure, and wherein the excitation induces a flow of ionic current having a DC component travelling in a pulsating and time-varying manner in the target region and effects induced vibration of electrons and molecules in the target region. The method and the system of the invention significantly reduce capital costs and require very low energy, they avoid environmentally unfriendly final products, and are able to result in effective corrosion protection of metallic structures in different surrounding conditions.
