Abstract: Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.

Abstract: A metal microparticle coated with metal hydride nanoparticles is disclosed. Some variations provide a material comprising a plurality of microparticles (1 micron to 1 millimeter) containing a metal or metal alloy and coated with a plurality of nanoparticles (less than 1 micron) containing a metal hydride or metal alloy hydride. The invention eliminates non-uniform distribution of sintering aids by attaching them directly to the surface of the microparticles. No method is previously known to exist which can assemble nanoparticle metal hydrides onto the surface of a metal microparticle. Some variations provide a solid article comprising a material with a metal or metal alloy microparticles coated with metal hydride or metal alloy hydride nanoparticles, wherein the nanoparticles form continuous or periodic inclusions at or near grain boundaries within the microparticles.

Abstract: We describe a new approach to fabricate polymeric materials with surface structures for applications as anti-reflective, anti-icing, superhydrophobic, superhydrophilic, de-wetting, and self-cleaning coatings. In some variations, a surface-textured layer comprises first microdomains and second microdomains each containing polymerized cross-linkable photomonomer, where the first microdomains have a higher average cross-link density than that of the second microdomains. The first microdomains and the second microdomains are in a peak-valley surface topology, providing surface texture with no filler particles. In some variations, a method to fabricate a surface-textured layer comprises: applying a cross-linkable photomonomer layer to a reflective substrate; exposing the photomonomer layer to a collimated light beam with no spatial variation, to initiate polymerization in first microdomains; and polymerizing other regions of the photomonomer layer to form second microdomains that are spatially separated from the first microdomains. The first microdomains have a higher average cross-link density compared to the second microdomains.
