The LLNL method is based on freeze‐casting of aerosolized and pressurized metal salt solutions and subsequent thermal processing. This method generates both porous particles with sizes down to one micron and macroscopic monoliths with nanometer scale ligaments/struts. The material's density can be controlled during the freeze‐dried stage. Compared to conventional approaches, this method…

By combining 3D printing and dealloying., researchers at LLNL have developed a method for fabricating metal foams with engineered hierarchical architectures consisting of pores at least 3 distinct length scales. LLNL’s method uses direct ink writing (DIW), a 3D printing technique for additive manufacturing to fabricate hierarchical nanoporous metal foams with deterministically controlled 3D…

LLNL researchers have conceived and performed studies relevant to the development of AM powders synthesized from asteroidal or meteoritical sources and the use of the powder as the feed source for additive manufacturing systems deployed in space. The method includes the steps of locating an asteroid or meteorite, making contact with the asteroid or meteorite, harvesting material from the…

LLNL has developed a new class of nitrogenous ligands for metals and their complexes chosen for their known propensity to chelate metal ions. Further chemical modifications of this scaffold were performed to furnish a novel series of ligands that are capable of coordinating different metal ions.

LLNL has developed a method for electroplating nickel oxide/hydroxide electrode materials with very high energy- and power density onto a current collector. The method is especially suitable for coating porous current collectors with high surface areas.
