Microscopy analysis using Transmission Electron Microscopy (TEM) was performed to obtain morphological descriptors such as envelop diameter, open area, aspect ratio, and projected area diameter.
TEM analysis showed that projected area diameter of MWCNTs appears to be in reasonable agreement with mobility diameter in the size range from 100 to 400 nm.
From equation (4), the projected tree diameter ( d ^ 2, i j ) was adjusted (Cao [2010]) so that the resulting stand basal area matches the prediction from the whole-stand model (equation 2): d ˜ 2, i j 2 = d 1, i j 2 + β d ^ 2, i j 2 − d 1, i j 2 (6).
Two shape factors calculated with the results of image analysis, circularity and projected area equivalent diameter (Heywood diameter), as well as span value for size distribution, were chosen as responses for analyses of variance.
Whereas the estimated crystallite diameter from XRD represents the volume average of the exposed sample (some mg), the TEM data for the mean (or median) particle diameter refers to the diameter projected value for a limited number of particles (~500).
It was found that the mobility equivalent diameter determined by the DMA is equivalent to the projected area equivalent diameter determined by the TEM for particles below 150 nm.
Groups of mono-area particles were visualized before and after the oxidation process and oxidation rates were determined from the change in projected area equivalent diameter by image-processing a series of TEM images.
AMF usually notably increases RSA traits (taproot length, total length, average diameter, projected area, surface area, volume, and number of first-, second-, and third-order lateral roots) of only PA-treated seedlings.
Image analysis system was used to provide geometric parameters of legume seeds, which are important for designing of engineering processes such as drying, milling, germination etc. Measured features of bean and lentil seeds were projected area, equivalent diameter, MaxFeret, MinFeret and thickness.
