Quali sono le principali applicazioni dei nanotubi di carbonio?
I nanotubi di carbonio sono stati recentemente impiegati nella progettazione della memoria meccanica, nei motori elettrici in nanoscala, nonché nello sviluppo di un sensore di idrogeno e di display flessibili e display touchscreen.
What is the shortest and thinnest carbon nanotube?
- The shortest carbon nanotube is the organic compound cycloparaphenylene, which was synthesized in 2008. The thinnest carbon nanotube is the armchair (2,2) CNT with a diameter of 0.3 nm. This nanotube was grown inside a multi-walled carbon nanotube.
What are the different types of carbon nanotubes?
- Types of carbon nanotubes and related structures. There is no consensus on some terms describing carbon nanotubes in scientific literature: both "-wall" and "-walled" are being used in combination with "single", "double", "triple" or "multi", and the letter C is often omitted in the abbreviation; for example, multi-walled carbon nanotube (MWNT).
How do you make carbon nanotubes with CVD?
- In the CVD process, manufacturers can combine a metal catalyst (such as iron) with carbon-containing reaction gases (such as hydrogen or carbon monoxide) to form carbon nanotubes on the catalyst inside a high-temperature furnace. Schematic view of CNT growth on catalyst particles during CVD.
What are the benefits of using carbon nanotubes for biological applications?
- Carbon nanotubes can also be chemically modified to present specific moieties (e.g., functional groups, molecules, and polymers) to impart properties suited for biological applications, such as increased solubility and biocompatibility, enhanced material compatibility and cellular responsiveness.
