By introducing twist during spinning of multiwalled carbon nanotubes from nanotube forests to make multi-ply, torque-stabilized yarns, we achieve yarn strengths greater than 460 megapascals. These yarns deform hysteretically over large strain ranges, reversibly providing up 48% energy damping, and are nearly as tough fibers used for bulletproof vests. Unlike ordinary these not degraded in strength by overhand knotting. They also retain their flexibility after heating air at 450 degrees C an...

The development of an earth-abundant, first-row water oxidation catalyst that operates at neutral pH and low overpotential remains a fundamental chemical challenge. Herein, we report the first nickel-based robust homogeneous catalyst, which can electrocatalyze in phosphate buffer. results DFT calculations verify O-O bond formation catalytic prefers HO-OH coupling mechanism from cis-isomer catalyst.
Challenges in fabricating all-perovskite tandem solar cells as modules rather than single-junction configurations include growing high-quality wide-bandgap perovskites and mitigating irreversible degradation caused by halide metal interdiffusion at the interconnecting contacts. We demonstrate efficient using scalable fabrication techniques. By systematically tuning cesium ratio of a methylammonium-free 1.8-electron volt mixed-halide perovskite, we improve homogeneity crystallization for...
Micro-/nanocapsules have received substantial attention due to various potential applications for storage, catalysis, and drug delivery. However, their conventional enclosed non-/polycrystalline walls pose huge obstacles rapid loading mass diffusion.
