Techniques are described for infiltrating a nanofiber yarn with an infiltration material and removing a surface layer of the infiltration material on at least a portion of the infiltrated nanofiber yarn. This enables an infiltration method by which the infiltration material is selectively disposed within an interior of a nanofiber yarn and not disposed on an exterior surface of at least a portion of a nanofiber yarn. Electrical connection can be established by mechanically connecting an electrode (e.g., a conductive clamp or fitting) directly to the exposed surface of the nanofiber yarn.

A coating composition which imparts antifog, antireflective, easy-cleaning, and/or antistatic properties to substrates coated therewith. The coating compositions utilize nanoparticles functionalized with amine groups and/or protected amine groups, and amine-reactive groups.

The present invention provides processes for producing porous silk fibroin scaffold material. The porous silk fibroin scaffold can be used for tissue engineering. The porosity of the silk fibroin scaffolds described herein can be adjusted as to mimic the gradient of densities found in natural tissue. Accordingly, methods for engineering of 3-dimensional tissue, e.g. bone and cartilage, using the silk fibroin scaffold material are also provided.

Micro-nano hybrid composites exhibiting desirable thermal conductivity levels due to the presence of specific ratios of graphite to graphene that have been found to reduce the overall thermal interface resistance. The composites are preferably epoxy matrix composites in some embodiments. Devices including the composites and methods of preparing the composites are also disclosed.

The disclosure describes composite fibers reinforced with inorganic nanostructures of high aspect ratio with homogeneous dispersion and alignment along the fiber axis and a process for producing said composite fibers.

A single crystal yttrium aluminum perovskite scintillator has a minimum thickness of at least 5 mm and a transmittance of at least 50% at a wavelength of 370 nm. A method for fabricating the yttrium aluminum perovskite scintillator includes acquiring a yttrium aluminum perovskite single crystal boule, annealing the yttrium aluminum perovskite single crystal boule in an oxygen containing environment to obtain a partially annealed crystal, and annealing the partially annealed crystal in an inert environment or a reducing environment to obtain the yttrium aluminum perovskite single crystal scintillator.

The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.

The present invention pertains to: a powder mixture for powder magnetic core obtained by mixing a lubricant, a solid lubricant, and a soft magnetic powder coated with an insulating coating, wherein a lubricant content is 0.1% by mass or more and 0.8% by mass and a solid lubricant content is 0.01% by mass or more and 0.2% by mass or less; and a powder magnetic core in which the powder mixture is used.
