In one embodiment, a magnet includes a plurality of layers, each layer having a microstructure of sintered particles. The particles in at least one of the layers are characterized as having preferentially aligned magnetic orientations in a first direction.
In one embodiment, a magnet includes a three-dimensional structure with nanoscale features, where the three-dimensional structure has a near net shape corresponding to a predefined shape.
A metal boride aerogel includes a three-dimensional aerogel structure comprising metal boride particles having an average diameter of less than one micron. A method is disclosed for forming a metal boride aerogel including dispersing boron nanoparticles in a solution of a metal salt, forming a boron-loaded metal oxide precursor gel using the dispersed boron nanoparticles in the solution of the metal salt, drying the boron-loaded metal oxide precursor gel to form a boron-loaded metal oxide precursor aerogel, and heating the boron-loaded metal oxide precursor aerogel to form a metal boride aerogel. The metal boride aerogel is essentially free of metal oxide.
