A highly sensitive and selective formaldehyde sensor was successfully fabricated using hybrid materials of nitrogen-doped double-walled carbon nanotubes (N-DWCNTs) and polyvinylpyrrolidone (PVP). Double-walled carbon nanotubes (DWCNTs) and N-DWCNTs were produced by high-vacuum chemical vapor deposition using ethanol and benzylamine. respectively. Purified DWCNTs and N-DWCNTs were drop... https://bxxrnqd57cnjl.theisblog.com/35130279/epimerization-of-ergot-alkaloids-in-feed
