LLNL uses the additive manufacturing technique known as Electrophoretic Deposition to shape the source particle material into a finished magnet geometry. The source particle material is dispersed in a liquid so that the particles can move freely. Electric fields in the shape of the finished product then draw the particles to the desired location to form a “green body”, much like an unfired…

LLNL has developed a liquid-free method that increases the overall mechanical resistance of self-supported, carbon nanotube assemblies through nanoscale reinforcement by gas-phase deposition of a thermally cross-linkable polymer. Polymer-reinforcement increases the strength of CNT yarns after crosslinking. For example, a minimal amount (<200 nm) of poly-glycidyl metacrylate (PGMA) deposited…

LLNL researchers have developed an alternative route to protective breathable membranes called Second Skin technology, which has transformative potential for protective garments. These membranes are expected to be particularly effective in mitigating physiological burden.

For additional information see article in Advanced Materials “Ultrabreathable and Protective Membranes with Sub-5…

The nanosphere synthesis process works when a nanostructured substrate is heated above a critical temperature in the presence of a small amount of metal on the nanostructured surface. The metal acts as a particular type of catalyst for nanowire formation. It is periodically segregated within the nanowire in a thermodynamically well-defined process as nanowires grow. The result is…
