Abstract: A titanium dioxide micro-nanocontainers, corrosion-resistant waterborne epoxy coatings and preparation method thereof, including preparation steps as follows: TiO2 micro-nano spheres are synthesized by applying hydrothermal method; a polyaniline layer doped with molybdate ions is deposited on the surface of TiO2 micro-nano spheres by adopting the method of in-situ chemical polymerization, TiO2/PANI-MoO42? micro-nano-spheres are obtained, then, polydopamine is encapsulated on the surface of TiO2/PANI-MoO42? micro-nano spheres to obtain titanium dioxide micro-nanocontainers; next, antirust filler, defoamer, dispersant and thickener are added into waterborne epoxy emulsion, then titanium dioxide micro-nanocontainers are added in the waterborne epoxy emulsion for dispersing and grinding, filtering and encapsulating to obtain component A; the waterborne epoxy curing agent and deionized water are mixed in proportion to obtain component B; component A is stirred, then it is mixed with the component B in proportion,

Abstract: Data storage systems having barriers that may reduce erasure flux and increase write-ability are provided. Data storage systems include a writing element. The writing element has a write pole with a flare region. A magnetic flux barrier is located along the write pole flare region. The magnetic flux barrier is illustratively made from an in-plane magnetically anisotropic material that has an easy plane of magnetization. In another embodiment, a data storage system includes a writing element having an air bearing surface and a shield at the air bearing surface. The shield has a magnetic permeability of approximately zero. The shield illustratively includes alternating layers of positive and negative permeabilities. The shield optionally includes a plurality of shields that may include top, bottom, and side shields.

Abstract: An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell.

Abstract: A method is provided for protection switching in an optical network. The method may include communicating a switch request for initiation of protection switching in response to a determination that at least a minimum frequency of interrupts indicating failure of an optical signal has occurred over a first period. The method may also include communicating a switch request for cessation of protection switching in response to a determination that no more than a maximum frequency of interrupts indicating failure of an optical signal has occurred over a second period.
