Table 1 Summary of physicochemical properties of AO nanowhiskers and generated aerosol

From: Murine pulmonary responses after sub-chronic exposure to aluminum oxide-based nanowhiskers

 

AO nanowhiskers

Structure

Crystalline

Phases

Al(OH)3 and Îł-AlOOH

Primary diameter1

3 ± 0.6 nm

Length1

~ 50 – 300 nm

Surface functionalization

O, O-H and H2O

BET surface area

320 ± 4 m2/g

Aerosol size distribution in whole-body exposure chamber2

GM = 150 nm GSD = 1.6 

Exposure concentration

3.3 ± 0.6 mg/m3

  1. 1 Primary diameter and length as measured by TEM in our laboratory. The length of the nanowhiskers could not be measured precisely since they appeared as tangled bundles. The length reported by manufacturer was 2800 nm.
  2. 2 Geometric mean mobility diameter (GM) and geometric standard distribution(GSD).
