A system for fabricating anisotropic magnetic nanowire composites includes a chamber for containing an ionic fluid. A hole in a wall of the chamber allows for the ionic fluid to be in contact with a porous template outside of the chamber, and a cathode and an anode provide an electric field across the ionic fluid and porous template. The electric field causes ionic materials in the ionic fluid to migrate into the pores of the porous template, therefore plating nanowires in the porous template. Constant distances and positions of the anode, cathode, a reference probe, and a stirring element allow for the fabrication of longer, more uniform nanowires, and for the generation of consistent magnetic nanowire composites across multiple fabrication sessions.

Method and system for preparation of a nanowire composite based on electroplating

Reusable filters for personal protective equipment (PPE) may prevent shortages of PPE and save fabrication time, resources, and money. Disclosed is a method and system for fabrication of nanofiber filter media for PPE. The method includes positioning a substrate to receive nanofibers thereon, providing a voltage gradient in a region of the substrate, and electrospinning nanofibers onto the substrate. The methods and associated systems allow autoclaving of the filter medium at temperatures of up to 300 degrees for sanitizing the filter medium. Additionally, the methods and associated system allow for the inclusion of an anti-pathogen agent in the nanofiber filter media.

A cathode for a multilayer solid-state electrochemical cell is described herein. The cathode comprises nanofibers of a cathode active material; particles of the cathode active material; and nanofibers of a cubic phase lithium lanthanum zirconium oxide (c-LLZO); all of which are dispersed in a polymeric matrix. Electrochemical cells comprising a solid-state electrolyte and the cathodes comprising the nanofibers of c-LLZO are also described herein.

Magnetic nanowire components may be used in passive radio-frequency device allowing for smaller size devices, lower power consumption, and on-chip packaging potential across a wide range of technologies. A method for fabricating magnetic nanowire component electronic devices include depositing a conductive device pattern and transmission lines onto a substrate, aligning and securing a magnetic nanowire component to the device pattern, packaging the device with an insulation layer. Alternatively, the conductive device pattern and transmission lines may be deposited on the magnetic nanowire component, and the magnetic nanowire component may then be attached to a substrate.

A solid-state electrolyte for a multilayer solid-state electrochemical cell is described herein. The electrolyte comprises a lithium electrolyte salt and nanofibers of a cubic phase lithium lanthanum zirconium oxide (c-LLZO), and a polymer interspersed with the nanofibers and electrolyte salt. Electrochemical cells comprising the solid-state electrolyte, and solid-state cathodes comprising the nanofibers of c-LLZO are also described herein.

A method for fabricating, and curing, nanocomposite adhesives including introducing nanoheater elements into a heat-curing adhesive to fabricate a nanocomposite adhesive, and providing a radio-frequency (RF) electromagnetic wave to the nanocomposite adhesive to heat, and cure the nanocomposite adhesive. The nanocomposite adhesive is physically applied to first and second materials to bond the first and second materials upon curing of the nanocomposite adhesive, and the RF electromagnetic wave has a frequency in the radio-frequency range, having energy that is transferred to the nanoheater elements by electromagnetic wave interactions with permanent and induced dipoles, intrinsic photon-phonon interaction, or interactions with nanoheater defects and grain structures.

A hybrid permanent magnet includes a first magnet (M1) having a first magnetic material and a second magnet (M2) having a second magnetic material different from the first magnetic material. The M2 magnet is deposited or assembled on a north pole surface and/or a south pole surface of the M1 magnet and the volume of the M2 magnet is less than or equal to the volume of the M1 magnet.
