Abstract: Forming a ferrite thin film laminate includes heating a layered assembly to form a laminate. The layered assembly includes a first coated substrate having a first ferrite layer opposite a first thermoplastic surface and a second coated substrate having a second ferrite layer opposite a second thermoplastic surface to form a laminate. Each coated substrate is formed by forming a ferrite layer on a surface of a thermoplastic substrate. The coated substrates are arranged such that the first ferrite layer contacts the second thermoplastic surface. Heating the layered assembly includes bonding the first coated substrate to the second coated substrate such that the first ferrite layer is sandwiched between a first thermoplastic substrate and a second thermoplastic substrate. The ferrite thin film laminate may include a multiplicity of coated substrates.

Abstract: Functionalized titanium nanotubes can be utilized to detect compounds of interest, for example peroxide-based explosives. The nanotubes may desirably be coated, for example with a silicon oxynitride coating, in order to improve detection performance and/or functionality in the presence of moisture, saline, or other conditions typically unfavorable to titanium nanotube detection devices and methods. Inexpensive, compact, reusable, and responsive sensors may be fabricated from the coated nanotubes.

Abstract: A ferrite layer having a columnar structure is formed, and ferrite flakes are separated from the ferrite layer. The ferrite flakes include a metal oxide having a spinel cubic crystal structure with a stoichiometry represented by AB2O4, where A and B represent different lattice sites occupied by cationic species, and O represents oxygen in its own sublattice.
