It is concluded that in down-flow units (FCC particles of 70 μm) catalyst particles evolve as particle strings with a relatively large size distribution: average cluster size ranging between 2.0 and 6.3 times of the average particle diameter with most of the particles strings having between 2.9 and 5.5 times of the average particle diameter.
The average particle size ranges between 15- and 500 nm.
In summary, the average particle diameter was between 40 nm with < 8% of Ag existing as dissolved Ag+ (Additional file 1: Table SI.1 for complete NP characterisation) [44].
Between the 28th frame and the 130th frame, the average particle shift per frame remained constant at 0.2 Å, and 95% of the measured particle shift stayed between 0.4 Å and 0.54 Å per frame.
For CdSe, the average particle density was found to vary between 2.5 g/mL for 10.61 Å particles and 2.9 g/mL for 20.15 Å particles.
The average particle size of as-prepared samples ranged between 0.5 and 1.5 μm.
The average particle size, obtained by transmission electron microscopy, ranged between 4 and 20 nm.
The average particle size of unprocessed attapulgite particles was about 15 µm, while the average particle size of the ultrafine precipitated attapulgite particles was between 0.1 µm and 1.35 µm based on different experimental conditions.
On the other side, for higher AgNO3 concentration (5 10-2 M), despite the increase of the average particle size and of the Ag coverage, the gap distribution between the particle protrusions and its average value are almost unaffected by the ink amount reacting with the porous silicon substrate (i.e., the number of printhead passes).
From the position of the absorption edge, the average particle size can be determined using Henglein's empirical relation between particle size and the absorption wavelength [30, 31].
