At increased nozzle diameter, (i) the particle mean diameter increases (from about 3.5 to 10.5 nm), (ii) higher ordering of the crystallographic network seems to occur, (iii) the dominance of the α-Fe and iron carbide phases is revealed.
Indeed, at a low PLA amount (40 mg), the particle mean diameter increases with increasing drug amount (see F9 versus F10, P < 0.0001).
Its intensity decreases and the mean diameter increases with increasing height above the burner due to coagulation and surface growth as the particles rise in the flame.
The geometric mean diameter increased from 24.03 to 24.70 mm and the sphericity varied between 0.82 and 0.83 as moisture content increased from 7.97% to 23.33% d.b., respectively.
Kernel length, width, thickness, and effective mean diameter increased from 6.24 to 6.66 mm, 3.65 to 4.22 mm, 3.43 to 3.85 mm, and 4.19 to 4.75 mm, respectively.
In the moisture range, seed length, width, thickness, arithmetic mean diameter, and geometric mean diameter increased linearly from 4.27 to 4.64 mm, 2.22 to 2.38 mm, 0.85 to 0.88 mm, 2.45 to 2.63 mm and 2.00 to 2.12 mm respectively with increase in moisture content.
In the moisture range, kernel length, width, thickness, arithmetic mean diameter, and geometric mean diameter increased linearly from 8.18 to 9.14 mm, 5.71 to 6.32 mm, 3.65 to 4.90 mm, 5.85 to 6.79 mm and 5.54 to 6.55 mm respectively with increase in moisture content from 8.95% to 17.12%.
In the moisture range, seed length decreased linearly from 4.74 to 4.61 mm, and width, thickness, arithmetic mean diameter, and geometric mean diameter increased linearly from 3.67 to 3.93 mm, 3.39 to 3.54 mm, 3.93 to 4.03 mm and 3.88 to 3.99 mm respectively with increase in moisture content.
The grain length, width, thickness and effective geometric mean diameter increased with increasing moisture content irrespective of millet varieties, while aspect ratio (which relates kernel width and length and determines whether grains will slide or roll on their flat surfaces during handling and processing) decreased with increase in moisture content.
The bright patches represent Ge nanoclusters whose density and mean size noticeably change after annealing (the mean diameter increasing from 2.5 to 7.5 nm).
The mean diameter increased from 61.3 ± 18.6 (s.d).
