Unleashing the potential of carbon nanotubes in …

2012-6-27 · Thanks to the very small diameter of carbon nanotubes, they cause far less damage. If the density of the tubes is too high, they cannot penetrate the cell, so researchers in the Technotubes project have developed a process to form nanotubes on an array of titanium columns spaced about 2 µm apart.

Detectors 4a and 4b are at the same level but on opposite sides: the aim is to survey any axial asymmetry in the velocity profile. Detectors 6 and 7 survey the gas behaviour from the end of the riser to the outlet of the FCC unit, while detectors 5–11 survey alyst recycling. The FCC unit is thus divided into sections of interest.

Hydrogen fluoride gas detector, Hydrofluoric acid, HF

2019-4-20 · Hydrogen fluoride effects on health. Hydrogen fluoride (HF) is a colorless gas featuring a pungent smell.This gas is very toxic by inhalation (R26), if swallowed (R28) or in contact with the skin (R27). It reacts with water to form hydrofluoric acid, which is very corrosive and extremely dangerous for the environment – it changes water pH.
