LLNL’s researchers use physical vapor deposition (sputter deposition or electron beam deposition) to coat an inert gasket material (i.e. PTFE) with a conductive metal (i.e. copper). The gas diffusion electrode overlaps onto the copper coated gasket to allow for electrical conductivity between the catalyst surface and the flow field/current collector of a CO2 electrolyzer. The coated gasket…

Using their computational design optimization, LLNL researchers have developed copper-based dilute alloy catalysts (contains <10 at.% of the minority metal alloy component) and demonstrated these novel catalysts have improved energy efficiency and selectivity of the methane conversion reaction. By alloying copper with a small amount of the electropositive minority metal element, the…

LLNL researchers have developed a novel simulation methodology using slow growth thermodynamic integration (SGTI) utilizing spliced soft-core interaction potential (SSCP). The approach to filling the molecular enclosures is a nonphysical one. Rather than filling the pores from the open ends this method creates steps in the algorithm that allow molecules to pass through the pore wall and…
![Graphite](/sites/default/files/styles/scale_exact_400x400_/public/2023-09/graphite.jpg?itok=2CQBn1ca)
LLNL’s innovation offers an alternate synthetic route to graphite at lower cost using a molten salt mixture of CaCl2-CaCO3-CaO. The synthetic production of graphite and other high-value carbon materials is accomplished in molten salt media via electrochemical reduction and transformation of the carbon from the carbonate ion. The broad electrochemical window of molten salts enables the…

The novel LLNL approach is to use projection microstereolithography (LAPµSL), starting with a photocurable methacrylate resin formulation consisting of a combination of a photoinitiator, photoabsorber, inhibitor, solvents, and other additives. Prior to use, the resin is pretreated to control viscosity for easier handling. The resin is fed to a LAPµSL printer which employs a near UV light…

The inventors have developed a 3% Yttria partially-stabilized Zirconia (3YZ) ceramic ink that produces parts with both nano and microporosity and is compatible with two AM techniques: DIW and projection microstereolithography (PμSL). The 3YZ nano-porous ceramic printed parts had engineered macro cavities measuring several millimeters in length, wall thicknesses ranging from 200 to 540 μm, and…
