Single-Walled Nanotubes TRIZ Cases

Near-monodisperse refractory metal aerosol catalysts enable in-growth chirality control of SWCNTs without damaging purification steps.

This case uses molecular oxygen, metal cations, and a reducing agent to create luminescent SWNT defects under mild, scalable conditions.

Divalent functional groups stabilize single-walled carbon nanotubes for near-infrared photon emission.

ATP-dependent DNA-ligase catalyzes phosphodiester bonds between functionalized nanotubes, resolving solubility and scalability constraints.

A dual polymer system selectively disperses semiconducting carbon nanotubes via centrifugation.

Diazotization creates sp3 defects on carbon nanotubes, resolving shallow exciton traps that cause dim photoluminescence in biosensing.

A magnet module attracts ferromagnetic impurities from carbon nanotubes using a tubular pipe and spherical magnets.

Limiting BET surface area to 100 m2/g prevents aggregation while maintaining dispersibility, resolving the trade-off between stability and ease of operation.

Specific redox potential dopants resolve the trade-off between semiconducting purity and production yield in conjugated polymer extraction.

Ball milling disperses nanotubes in metal powder to prevent aggregation, while spark plasma sintering densifies the mixture for high strength.

Segmented polymers resolve selectivity versus spacing contradictions to align nanotubes.

Silicon oxide particles in metal catalyst targets enable high-purity single wall carbon nanotube synthesis, resolving furnace clogging and yield loss.
