Article Synopsis
- Incorporating boride nanocrystals into aluminum alloys enhances their mechanical properties, particularly strength and hardness.
- Using molten salts synthesis, researchers created superhard hafnium diboride nanoparticles that remain stable during the manufacturing of aluminum nanocomposites.
- Structural analysis shows strong interactions between the nanoparticles and aluminum matrix, resulting in reduced grain size and improved hardness, indicating potential for lightweight applications.
Most existing methods for additive manufacturing (AM) of metals are inherently limited to ~20-50 μm resolution, which makes them untenable for generating complex 3D-printed metallic structures with smaller features. We developed a lithography-based process to create complex 3D nano-architected metals with ~100 nm resolution. We first synthesize hybrid organic-inorganic materials that contain Ni clusters to produce a metal-rich photoresist, then use two-photon lithography to sculpt 3D polymer scaffolds, and pyrolyze them to volatilize the organics, which produces a >90 wt% Ni-containing architecture.

Case Reports: We describe here three cases of polymyositis with trigeminal or facial neuropathy. Patients had muscular weakness, myalgia, rhabdomyolysis, endomysial infiltration with necrosis and regeneration at biopsy of muscle and, for two of them, a myopathic pattern at electromyogram.
