LLNL researchers have introduced the use of a kirigami inspired substrate to act as a mechanical transducer, which converts macroscale stretching motion into localized bending.  The performance of photo-piezocatalysts made with aligned arrays of photocatalytic nanomaterials on the kirigami shaped substrate yields significant enhancements (~250%) in the degradation of dyes.

To address these challenges and explore the scale-up science of MXene, LLNL researchers have developed a scalable solution-phase synthesis method to generate MXene with over 70% production yield via top-down exfoliation approaches with non-aqueous solvents and salts.  The novel method is a dramatic improvement compared to conventional approaches (10-20%). Furthermore, the shielding…

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.
