A skeletal composite material includes an internal skeleton structure surrounded by a matrix material. The skeleton structure and the matrix are made of different materials having different properties. It should be appreciated that the skeleton structure and the matrix can be made of any suitable material including metal, ceramic, carbon, polymers, or combinations of these materials. Preferably, the skeleton structure and/or the matrix are made primarily of metal or ceramic. The skeletal composite material can be made by filling a skeleton structure with powder, compacting the skeleton structure and powder to form a preform, and consolidating the preform to form the skeletal composite material.

Disclosed is a method for manufacturing a metallic nanowire transparent electrode, including generating a metallic nanowire and chemically reducing the metallic nanowire to connect adjacent metallic nanowires.

Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.

A composition includes a carbon nanotube (CNT)-infused metal fiber material which includes a metal fiber material of spoolable dimensions, a barrier coating conformally disposed about the metal fiber material, and carbon nanotubes (CNTs) infused to the metal fiber material. A continuous CNT infusion process includes: (a) disposing a barrier coating and a carbon nanotube (CNT)-forming catalyst on a surface of a metal fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the metal fiber material, thereby forming a carbon nanotube-infused metal fiber material.

A high quality porous aluminum body, which has excellent joint strength between the porous aluminum body and the aluminum bulk body, and a method of producing the porous aluminum complex, are provided.

Some embodiments of the present disclosure relate to an additively manufactured transport structure. The transport structure includes cavities into which components that use an external interface are inserted. A plurality of components are assembled and integrated into the vehicle. In an embodiment, the components and frame are modular, enabling reparability and replacement of single parts in the event of isolated failures.

A fine metal linear body is provided in which the sintering temperature is lower than that in conventional examples. The fine metal linear body has a length of 0.5 to 200 m and a thickness of 30 nm to 10 m. When a length of a crystal of a metal constituting the fine metal linear body, in a direction in which the fine metal linear body extends, is taken as X, and a length thereof in a direction orthogonal to the direction is taken as Y, an X/Y value, which is a ratio of the X to the Y, is 4 or less, in three boundary regions when dividing the length of the fine metal linear body into four equal parts along the extending direction.
